PLEASE READ AND SAVE!
THANK YOU for purchasing this 3-in-1 Smoke + Fire + Carbon Monoxide Smart Alarm.
This alarm contains a 10 year permanent power sealed battery to provide continuous protection–even in the event of a power outage. The sealed battery will last for approximately 10 years. This manual includes important information regarding where to install the alarm, how to operate, maintenance, testing and product features. It also includes tips and information which could help protect you and your family.

ALARM TECHNOLOGY & FEATURES

This 3-in-1 combination smoke + fire + carbon monoxide (CO) alarm requires constant 120 VAC power to operate properly. The 10 year sealed battery provides continuous protection in the event of a temporary power outage.

There are three basic smoke alarm types: Universal Smoke Sensing Technology®, Ionization and Photoelectric.
Universal Smoke Sensing Technology® is an ionization alarm containing patented Smart Alarm Technology. Alarms containing Universal Smoke Sensing Technology are effective at detecting fast flaming fires faster than the maximum allowable alarm limit, and are effective at detecting slow smoldering fires.
Ionization smoke alarms are typically more effective at detecting fast flaming fires—fires which consume combustible materials rapidly and spread quickly. Sources of these fires may include paper burning in a wastebasket, or kitchen grease fires.
Photoelectric smoke alarms, on the other hand, are typically more effective at detecting slow smoldering fires—fires which burn for hours before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
Installing alarms containing Universal Smoke Sensing Technology ensures maximum detection of both types of fires from a single alarm, while eliminating the need for a combination of ionization and photoelectric smoke alarms.

The enclosed alarm is a 3-in-1 Universal Smoke Sensing Technology®
Smoke + Fire + Carbon Monoxide Smart Alarm.

KEY PRODUCT FEATURES

Smart Alarm Technology virtually eliminates nuisance alarms caused by non- hazardous sources such as every day cooking smoke and steam
Permanent Power battery backup provides continuous protection—even in the event of an AC power outage. Eliminates low battery chirps. Never replace batteries.
Lithium Free 10 Year Sealed Power Supply features Duracell® Duralock Power Preserve™ Technology alkaline batteries providing a safer, greener alternative

ALARM LIMITATIONS AND FUNCTIONS

IMPORTANT: ALARMS WILL NOT WORK WITHOUT POWER. Therefore, installing an alarm with a sealed battery or an alarm powered from two different power sources can give an extra measure of protection. A hardwired alarm with backup battery power will provide protection in the event of an AC power failure. Battery operated alarms cannot work if the batteries are missing, disconnected or dead. If you are concerned about the limitations of the battery or AC power, install both types of alarms.
PROPERLY LOCATE THE ALARM TO AVOID NUISANCE ALARMS. Using an ionization smoke alarm without Universal Smoke Sensing Technology in a smokey area, such as a kitchen, or in a high humidity area near a shower, can cause nuisance/false alarms. Also, humid areas near a shower can cause nuisance false alarms.
DO NOT TURN OFF THE AC POWER OR DEACTIVATE THE BATTERY TO QUIET A NUISANCE/FALSE ALARM. The alarm will not provide protection if it is not receiving power. Properly locate the alarm to avoid nuisance/false alarms.
SMOKE, CO OR GAS ALARMS MAY NOT ALWAYS WARN ABOUT DANGERS CAUSED
BY CARELESSNESS. Safety hazards such as smoking in bed, violent explosions, escaping gas, improper storage of flammable materials, overloaded electrical circuits, children playing with matches, natural causes such as lightning and arson. Prevention and appliance maintenance is the best safeguard.
INSTALLING ALARMS MAY MAKE YOU ELIGIBLE FOR LOWER INSURANCE RATES, BUT ALARMS ARE NOT A SUBSTITUTE FOR INSURANCE. Home-owners and renters alike should continue to insure their lives and properties.
SMOKE ALARMS CANNOT DETECT FIRES IF THE SMOKE DOES NOT REACH THEM. Smoke from fires may not reach the sensing chamber and set off the alarm. Do not obstruct airflow around the smoke alarm or place in areas of obstructed airflow.
SMOKE ALARMS MAY NOT BE EFFECTIVE IN VARIOUS AREAS. For example: (1) Fires where the victim is intimate with fire due to a person’s clothes catching fire while cooking;
(2) Fires where the smoke is prevented from reaching the alarm due to a closed door or other obstruction; (3) Incendiary fires where the fire grows so rapidly that an occupant’s egress is blocked even with properly located alarms.
SMOKE ALARMS MAY NOT DETECT FIRE ON ANOTHER FLOOR OR AREA OF THE HOME. Recommended minimum protection is at least one smoke alarm inside every bed-room, outside every sleeping area and on every level of the residence. Interconnected alarms may provide earlier warning than stand-alone alarms since all alarms will sound when the initiating alarm sounds.
SMOKE ALARMS CANNOT PREVENT OR EXTINGUISH FIRES.
ALARMS CAN ONLY SENSE CO WHICH REACHES THE ALARM SENSOR. Carbon monoxide may be present in other areas of the dwelling without reaching the alarm. CO may be present on one level of the dwelling and not reach the alarm installed on a different level. For example, CO in the basement may not reach an alarm on the second level, near the bedrooms. For this reason, we recommend you provide complete coverage by placing a combination alarm on every level of the dwelling.
ALARMS MAY NOT BE HEARD. The horn in this alarm meets or exceeds current standards, but it may not be heard if: (1) The alarm is located outside a closed or partially closed door; (2) Residents recently consumed alcohol or drugs; (3) The sound of the alarm is drowned out by noise from stereos, TV’s, air conditioners or other appliances; (4) Residents are hearing impaired or (5) Residents are sleeping. Current studies have shown alarms may not awaken all sleeping individuals and that it is the responsibility of individuals in the household who are capable of assisting others to provide assistance to those who may not be awakened by the alarm sound or to those who may be incapable of safely evacuating the area unassisted.
ALARMS ARE NOT FOOLPROOF. Test alarms weekly to ensure continued protection.
ALARMS HAVE A LIMITED PRODUCT SERVICE LIFE. This alarm should be replaced immediately if it is not operating properly. If the self-diagnostic test reveals a malfunction, the service signal will warn it is time to replace the alarm.
Alarms should always be replaced after 10 years.
DO NOT PAINT THE ALARM. Paint may clog the openings to the sensing chambers and prevent the alarm from operating properly.
DO NOT STAND TOO CLOSE TO THE ALARM WHEN IT IS SOUNDING. It is loud to wake occupants in an emergency. Exposure to the horn at close range may harm your hearing.
DO NOT TAMPER WITH THE SEALED RADIOACTIVE SOURCE. This alarm contains an extremely small amount of a radioactive element in the ionization chamber—less than 1 mi-crocurie (37 kilobecquerel), of a radioactive element, Americium 241. This element is used to detect combustion products. The source is manufactured and distributed under license from the U.S. Nuclear Regulatory Commission; and meets or exceeds government standards. The consumer is exempt from any licensing requirements.

INSTALLATION INSTRUCTIONS

WARNING!
IMPORTANT CONSIDERATIONS THIS ALARM HAS BEEN DESIGNED WITH A PRODUCT END-OF- SERVICE LIFE SIGNAL WHICH WILL SOUND AFTER APPROXIMATELY 10 YEARS OF OPERATION FROM INITIAL POWER UP.
NOTE: Manufacturer recommends replacement of this alarm 10 years after date of installation.

WHERE THIS ALARM SHOULD BE INSTALLED
This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure compliance with Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical problems may consider using warning devices which provide audible and visual warnings for carbon monoxide concentrations under 30 ppm.
IMPORTANT: This alarm must be mounted on a ceiling or a wall.
It is not designed for use as a tabletop device.
For maximum protection, install an alarm inside every bedroom, outside every sleep area, and on every level of the home including basements and finished attic spaces.

Temperature limits for proper operation are 40ºF to 100ºF (4.4ºC to 37.8ºC).
Install an alarm in each room where the occupant closes the door while sleeping.
Install an alarm in every family living unit containing a fuel-burning appliance, fireplace, or an attached garage.
Alarms should be centrally located outside of each separate sleeping area in the immediate vicinity of the bedrooms. Where bedrooms are separated and audibility of the alarm to occupants within the bedroom area could be seriously impaired, more than one alarm may be needed.
Protect the escape route, as the bedrooms are usually farthest from an exit. If more than one sleeping area exists, locate additional alarms in each sleeping area. If a hall is more than 40 feet (12 meters) long, install an alarm at each end of the hallway.
Add additional alarms to protect any stairway, as stairways may act like chimneys for smoke and heat.
Locate at least one alarm on every floor level.
Locate an alarm in any area where a smoker sleeps or where electrical appliances are operated in sleeping areas.
Smoke, heat and other combustion products rise to the ceiling and spread horizontally. Mounting the alarm on the ceiling in the center of the room places it closest to all points in the room. Ceiling mounting is preferred in ordinary residential construction. However, in mobile homes, wall mounting on an inside partition is preferred to avoid the thermal barrier that may form at the ceiling.
When mounting the alarm on the ceiling, locate it a minimum of 4” (10cm) from a side wall or corner (see Diagram A).
When mounting the alarm on a wall, if local codes allow, use an inside wall with the top edge of the smoke alarm a minimum of 4” (10cm) and a maximum of 12” (30.5cm) below the ceiling/wall intersections (See Diagram A).

Existing Homes:
The NFPA requires smoke alarms or combination alarms on every level and outside each sleeping area in existing construction. An existing household with one level and one sleeping area is required to have one smoke alarm.

New Construction Homes and Manufactured Homes:
The NFPA requires AC-powered, interconnected smoke alarms to be installed inside each bedroom, outside each bedroom area, and on every level of the home. They also require a minimum of two AC-powered, interconnected smoke alarms or combination alarms in any new construction home.

Sloped Ceilings (Peaked Ceilings):
Smoke alarms or combination alarms mounted on a peaked ceiling shall be located within 36 in. (914 mm) horizontally of the peak, but not closer than 4 in. (102 mm) vertically to the peak.

Sloped Ceilings (Shed Ceilings):
Smoke alarms or combination alarms mounted on a sloped ceiling having a rise greater than 1 ft. in 8 ft. (1 m in 8 m) horizontally shall be located within 36 in. (914 mm) of the high side of the ceiling, but not closer than 4 in. (102 mm) from the adjoining wall surface.

Tray-Shaped Ceilings:
Smoke Alarms or combination alarms shall be installed on the highest portion of the ceiling or on the sloped portion of the ceiling within 12 in. (305 mm) vertically down from the highest point.

Mobile Home Installation:
For minimum protection, smoke alarms should be installed in compliance with H.U.D. Manu-factured Home Construction Safety Standards, Title 24 CFR, Section 3280.208 and Section 3282. For additional protection, see Single Story Residence smoke alarm requirements/rec-ommendations for Existing Homes and New Construction Homes.
Note: For mobile homes built before 1978, install smoke alarms or combination alarms on in-side walls between 4” and 12” from the ceiling (older mobile homes have little or no insulation in the ceiling). This is especially important if the ceiling is unusually hot or cold.
Install smoke alarms or combination alarms inside each bedroom and in the hallway outside each separate sleeping area.

RECOMMENDED PLACEMENT:

NOTE: For any location, make sure no door or other obstruction could prevent the smoke or carbon monoxide from reaching the alarm.

WHERE THIS ALARM SHOULD NOT BE INSTALLED

Installation in an improper location can affect the sensitive electronic components in this alarm.
This alarm is not suitable for installation in hazardous locations as defined in the National Electrical Code.

To avoid causing damage to this alarm, to provide maximum protection, and to prevent unnecessary alarms, DO NOT LOCATE THIS ALARM:

In extremely humid areas. This alarm should be at least 10 feet (3m) from a bath or shower, sauna, humidifier, vaporizer, dishwasher, laundry room, utility room or other source of high humidity.
In very cold or very hot environments or in unheated buildings or outdoor rooms where the temperature can go below or above the operating range of the alarm.
In garages, crawl spaces and unfinished attics.
In turbulent air, such as near ceiling fans, heat vents, air conditioners, fresh air returns or open windows. Blowing air may prevent smoke or CO gas from reaching the sensors.
In extremely dusty, dirty or greasy areas. Installation in these areas could lead to nuisance alarms, may damage or contaminate the alarm.
In the garage, vehicle exhaust can contain some carbon monoxide. These levels are higher when the engine is first started. Within hours of starting a vehicle and backing it out of the garage, the levels present over time can activate the alarm and become a nuisance.
Within 5 feet (1.5m) of heating or cooking appliances. To reduce nuisance alarms, we recommend 15 feet.
Less than 12 inches (306mm) away from fluorescent lights. Electrical noise can interfere with the operation of the alarm.
In the kitchen, some gas appliances can emit a short burst of CO or gas upon startup. This is normal. If this alarm is installed too close to these appliances, it may sound often and become a nuisance.
Less than 20 feet (6m) from the sources or combustion particles such as a stove, furnace, water heater, non-electric space heater. In areas where a 20 foot (6m) distance is not possible i.e. modular, mobile or smaller homes, it is recommended the alarm be placed as far from these fuel-burning sources as possible.
Where heavy furniture drapes or other objects will not block the sensor.
Peaks of vaulted ceilings, “A” frame ceilings or gabled roofs.
Alarms are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.
Do not install this alarm into an electrical circuit controlled by a dimmer or switch or ground fault circuit interrupter.

NOTES: Good ventilation is recommended when household cleaning supplies or similar contaminants are used.
Excessive spillage or reverse venting of fuel-burning appliances caused by outdoor ambient conditions, such as: (1) Wind direction and/or velocity, including high gusts of wind; (2) Heavy air in the vent pipes with cold/humid air with extended periods between cycles; (3) Negative pressure differential resulting from the use of exhaust fans; (4) Simultaneous operation of several fuel-burning appliances competing for limited internal air; (5) Vent pipe connections vibrating loose from clothes dryers, furnaces or water heaters; (6) Obstructions in or unconventional vent pipe designs which can amplify the above situations.
These placement recommendations are intended to keep alarms at a reasonable distance from a fuel-burning source and reduce unwanted/nuisance alarms. Nuisance alarms may occur if an alarm is placed directly next to a fuel- burning source. Ventilate these areas as much as possible.

MOUNTING INSTRUCTIONS

WIRING INSTRUCTIONS

Caution! Read Carefully DANGER! ELECTRICAL SHOCK HAZARD
Before beginning installation, turn off main power to the circuit controlling the area where of this alarm will be wired—at the circuit breaker or fuse box. Failure to turn off the power before installation may result in serious electrical shock, injury or death.

WARNING! Make sure the alarm will not receive excessively noisy power.
Examples of noisy power could be major appliances on the same circuit, power from a generator or solar power, light dimmer on the same circuit or mounted near fluorescent lighting.
Excessively noisy power may cause damage to the alarm.

WARNING! This alarm cannot be operated from power derived from a square wave, modified square wave or modified sine wave
inverter. These types of inverters are sometimes used to supply power in off- grid installa-tions, such as solar or wind derived power sources. These power sources may produce high peak voltages which will damage the alarm.

Installation of this alarm must conform to the electrical codes in your area;
Article 760 of the National Electrical Code, NFPA 72, 101; SBC (SBCCI); UBC (ICBO); NBC (BOCA): OTFDC (CABO), and any other local or building codes that may apply. Wiring and installation must be performed by a licensed electrician. Failure to follow these guidelines may result in injury or property damage.

This alarm must be powered by a 24-hour, 120V AC 60 Hz circuit, 100mA maximum. Be sure the circuit cannot be turned off by a switch, dimmer or ground fault circuit interrupter. Failure to connect this alarm to a 24-hour circuit may prevent it from providing constant protection.

IMPORTANT: Do not subject this alarm to megger, high voltage or high-pot tests. Remove the alarm(s) before high-potting tests occur on the circuit or system. (Ref. Section 550-17, National Electrical Code, 2014 Edition).

IMPORTANT: Improper wiring to the AC connector will cause failure to operate, damage to the alarm, or shock hazard; and will lead to a non- functioning alarm. Never connect the hot or neutral wires to the yellow interconnect wire. Never cross hot and neutral wires between interconnected alarms.

STAND ALONE INSTALLATION

IMPORTANT: Read all instructions before using this alarm.
For alarms used as a single, stand-alone, non-interconnected installation, the yellow wire will not be used. Do not connect the yellow wire to anything. Insulate/tape the end of the wire to ensure the yellow wire cannot contact any metal parts or junction box.

Turn off AC power to the circuit before wiring the AC quick connector
There are three pigtail wires (black, white and yellow) in the AC quick connector

tabs on the connector snap securely into place.
Push the excess wire back into the electrical junction box.
CAUTION: The AC power should still be turned off at this stage.
Position the base of the alarm over the mounting bracket and turn it clockwise until the alarm snaps securely into place.
Activate the Permanent Power sealed battery by removing the battery pull tab. The alarm will sound one long beep to let you know it is powered.
NOTE: Once activated, the alarm cannot be turned off without permanent deactivation.
The alarm will remain on for approximately ten years.
If you are only installing one alarm, turn on the AC power. The green LED should be on to indicate power. The red LED should flash on once approximately every two minutes.
NOTE: It is best to “reset” the alarms before initial test is performed. The reset instructions can be found on page 11.
Test the alarm. The alarm will sound 3 beeps, followed by a 6 second pause, then 4 beeps. The green LED will be on and the red smoke LED will blink in sync with the 3 beeps and the red CO LED will blink in sync with the 4 beeps. If the alarm does not test properly, turn off power. Recheck your wiring and connections and confirm the battery pull tab has been removed. Restore power and re-test. If there is still a problem, call customer service. Do not attempt to fix the alarm.

WARNING! ELECTRICAL SHOCK HAZARD. Do not restore power until all alarms are completely installed. Restoring power before installation is complete may result in serious electrical shock, injury or death.

Repeat steps 1-10 above for installation of multiple alarms.
INTERCONNECTED ALARMS INSTALLATION

WARNING!
The wiring to be used shall be in accordance with the provisions of Articles 210 and 300.3(B) of the National Electrical Code, ANSI/NFPA 70, NFPA 72 and any other local building codes that may apply. Wiring should be performed by a licensed electrician.

Turn on the AC power. The green LED should be on to indicate power. The red LED should flash on once approximately every two minutes.
NOTE: It is best to “reset” the alarms before initial test is performed. The reset instructions can be found on page 11.
Test the alarm. IMPORTANT: All interconnected alarms in the interconnected system should sound. This test is only testing the interconnect signal between each alarm. It will not test the operation of each alarm. To verify all alarms are operating correctly, press the test button on each alarm individually.

Repeat steps 1-10 above for installation of multiple interconnected alarms.
ELECTRICAL SHOCK HAZARD. Do not restore power until all alarms are completely installed. Restoring power before installation is complete may result in serious electrical shock, injury or death.
If any alarm in the series does not sound during testing, turn off power, recheck connections and wiring and confirm the battery pull tab has been removed. Restore power and re-test. If there is still a problem, call customer service. Do not attempt to fix the alarm.

INTERCONNECTION & COMPATIBILITY

Interconnected alarms can provide earlier warning than stand-alone alarms, especially the hazard occurs in a remote area of the dwelling. When alarms are interconnected, all alarms will sound when one alarm first sounds.

WARNING! To prevent damage, do not connect this alarm to any other type of alarm or auxiliary device. Connecting incompatible devices or alarms may damage this alarm or prevent it from operating properly.
This alarm may be interconnected with a total of not more than 24 interconnected devices, i.e., as many as 11 other USI Electric or Universal Security Instruments model smoke alarms or combination smoke and carbon monoxide or smoke and carbon monoxide/natural gas alarms; 6 other initiating alarms which may be a combination of USI Electric or Universal carbon monoxide alarms and heat alarms; and 6 other non-initiating devices such as USI Electric relay modules.
This alarm can be interconnected with the following models: MDSCN111, MICN109, MCN108, USI-1103, USI-1203, USI-1204, USI-1208, USI-1209, USI-1213, USI-5204, USI-3204, 5304, MI106, MDS107, MP117, USI-2430, USI-960, MI106S, MIC1509S, MPC122S, MP116S.
When any one of these interconnected models sounds, it will trigger the corresponding alarm within the interconnected system with respect to their sensing capabilities. Natural gas detection is only present in models MDSCN111, MICN109 and MCN108, therefore a natural gas alarm will NOT trigger the alarm of non-natural gas sensing models within an interconnected system.

The following alarms can trigger Quick Find® Alarm Origination, but will not indicate Alarm Origination on an interconnected system: USI-1103, USI-1203, USI-1204, USI-1208, Part USI-1209, USI-1213, USI-5204, USI-3204, USI-7795, USI-2430.
The following alarms cannot be reset through an interconnected system: USI-1103, USI-1203, USI-1204, USI-1208, USI-1209, USI-1213, USI-3204, USI-2430, USI-7795.
NOTE: Alarms without battery backup will not respond during an AC power failure.
Interconnected CO alarms or CO alarm circuit of combination smoke and CO alarms will only respond if a CO alarm/event initiates the alarm. All other alarms remain silent.
Interconnected smoke alarms, heat alarms and relay modules will only respond if a smoke alarm/event or heat alarm/event initiates the alarm. All CO alarms remain silent.

IMPORTANT: The USI relay module model USI-960 will not respond if a CO or gas alarm/event initiates the alarm and it will not respond during an AC power failure.

BATTERY-BACKUP MODE: The green light is off. The red LED blinks on once approximately every two minutes. The horn is silent. The battery backup is designed to provide continuous power to the alarm in the event of an AC power outage.
CAUTION! This combination smoke & fire & carbon monoxide alarm has separate alarm sounds. This alarm is not designed to detect any other gas. Carbon monoxide and smoke may be present in other areas. The alarm will only indicate the presence of CO or smoke which reaches the sensor

TEST SEQUENCE: The horn beeps 3 times with a 6 second pause and then beeps 4 times and continues until the air is cleared. The green LED is on. The red smoke LED blinks on in synch with the 3 beeps. The red CO LED blinks in sync with the 4 beeps.

This alarm incorporates the NFPA recognized horn signal for evacuation.
LOCAL ORIGINATING SMOKE ALARM CONDITION: The horn beeps 3 times with a 2 second pause and continues until the air is cleared. The green LED is on. The red smoke LED blinks on in synch with the 3 beeps. The red CO LED is off.

NON-ORIGINATING SMOKE ALARM CONDITION: Another interconnected alarm has sensed smoke, causing all the other interconnected alarms to sound. The horn beeps 3 times with a 2 second pause and continues until the air is cleared. The green LED is on. The red smoke LED is off. The red CO LED is off.

LOCAL ORIGINATING CO ALARM CONDITION: The horn beeps 4 times with a 5 second pause and continues until the air is cleared. The green LED is on. The red smoke LED blinks on every two minutes. The red CO LED blinks on in sync with the 4 beeps.

NON-ORIGINATING CO ALARM CONDITION: Another interconnected alarm has sensed CO, causing all the other interconnected alarms to sound. The horn beeps 4 times with a 5 second pause and continues until the air is cleared. The green LED is on. The red smoke LED blinks on approximately every two minutes. The red CO LED is off.

SENSOR TROUBLE: This alarm contains multiple self-diagnostics. If a sensor fault is detected, the horn chirps 3 times approximately every 60 seconds. The green LED is on. The red smoke LED blinks on once approximately every two minutes. The red CO LED is off. The trouble signal cannot be silenced. Reset the alarm. If this does not clear this trouble signal, deactivate the alarm. Refer to the “alarm deactivation section.” Replace alarm immediately.

RESET ALARM: Press the test/silence button for 10-15 seconds, then release. This will clear the alarm origination. Be sure to reset alarms after every alarm event.

QUICK FIND® ALARM ORIGINATION FEATURE: To quickly identify the originating alarm (the first alarm to sound in an interconnected system) after all the alarms have stopped sounding

Press and release the test/silence button on any interconnected alarm. After releasing the button, the test sequence will sound on all the interconnected alarms and last for approximately 5-20 seconds.
Once the test sequence ends, the originating alarm will continue to sound for approximately 60 seconds which provides ample time to locate the originating alarm.
Remember to reset the originating alarm in order to clear the Quick Find® and return the system to normal operation
NOTE: In a non-interconnected installation, it is necessary to test each alarm by pressing and releasing the test/silence button to determine the originating alarm.

PRODUCT END-OF-SERVICE LIFE ALARM/LOW BATTERY WARNING: When it is time to replace this alarm, which is approximately 10 years of operation from initial power up, the alarm will provide audible and visual warnings. The product end- of-service life warning cannot be silenced. The horn chirps 2 times approximately every 60 seconds. The green LED is on. The red smoke LED blinks on approximately every 2 minutes. The red CO LED is off. Deactivate the alarm. Refer to the “alarm deactivation section.” Replace alarm immediately.

USING THE SILENCE FEATURE

WARNING! NEVER ignore any alarm. If the alarm sounds and it is not being tested, it is warning of a potentially dangerous situation which requires immediate attention.
NEVER disconnect the power to your alarm to silence the horn—use the Silence feature.
Disconnecting the alarm removes your protection!

IMPORTANT! The Silence feature is intended to temporarily silence the alarm warning.
It will not correct a smoke or CO problem.

This alarm will not operate until it is activated and properly installed. This alarm should be tested immediately after installation and then tested weekly after that. If the alarm ever fails to test correctly, have it replaced immediately. If the alarm is not working properly, it cannot alert you to a problem. This alarm must have 120 Volt AC and activated sealed battery power to operate properly. If the battery is dead or deactivated, the alarm will not operate properly. The sealed battery cannot be replaced. The cover of this 10 year permanent power tamper proof alarm is sealed, and cannot be removed.

In the event of a smoke alarm, do not use the Silence feature until the source of the alarm has been identified and safe conditions exist.
The Silence feature is intended to temporarily silence the horn while identifying and correcting the problem. To use the Silence feature, press and release the test/silence button until the horn is silent if it was the initiating alarm. If the test/silence button is pressed while the alarm is in the silence mode, the alarm will start sounding again.

The CO alarm Silence feature can be activated by a press and release of the test/silence button on the initiating alarm while in alarm condition. The alarm will remain silent for approximately 5 minutes, depending on the level of CO detected. The red CO LED will blink on approximately every 10 seconds. If CO levels drop below the alarm levels, the alarm will remain silent and return to normal operation. If CO levels remain constant or increase, the alarm will sound again. This indicates a potentially dangerous situation. Ventilate the area.

The smoke alarm Silence feature can be activated by press and release of the test/silence button on the initiating alarm while in alarm condition. The alarm will remain silent for approximately 8-12 minutes, depending on the level of smoke detected. The red smoke LED will blink on approximately every 10 seconds. If smoke levels have not cleared during the silence period, the alarm will sound again. This indicates a potentially dangerous situation. Ventilate the area. If the alarm remains silent, the smoke levels have dropped and the alarm will return to normal operation. If smoke levels remain constant or increase, the alarm will sound again.

TESTING INSTRUCTIONS

WARNING!
NEVER use an open flame of any kind to test this alarm. You may accidentally damage or set fire to the alarm or to your home.

NEVER use vehicle exhaust to test the alarm! Exhaust may cause permanent damage and voids the warranty.

NEVER use a gas range or an open flame of any kind to test this alarm. You might accidentally damage or set fire to the alarm or to your home.
CAUTION: Continuous exposure to the high sound level of this alarm over an extended period of time may cause hearing loss. Due to the loudness, we suggest that you place your fingers over the sounder opening, or step back from the alarm while testing.
NOTE: The alarm horn loudness meets or exceeds current UL standards of 85 dB at 10 feet (3 meters).

WEEKLY TESTING: This alarm is designed to act as a monitor, not for use as a short-term testing device, or to perform a quick check for the presence of CO or smoke. The built-in test switch accurately tests the alarm operation as required by ANSI/UL 2034/UL 217 Standards for Safety. If at any time the alarm does not perform as described when tested, replace it immediately. Weekly testing is required to ensure proper operation.

This will discharge the alarm battery and stop the alarm chirping after approximately on minute. The alarm is now ready for disposal.
The deactivation key cannot be removed and the alarm cannot be re-attached to the mounting bracket.
Be sure to install a new alarm immediately.

Once this alarm has been deactivated/turned off:
WARNING!

The alarm cannot be re-activated
The alarm cannot be re–attached to the bracket
The alarm will no longer detect smoke or carbon monoxide
The alarm contains no serviceable parts

WHAT YOU SHOULD KNOW ABOUT CO

Carbon monoxide (CO) is an insidious poison. It is a colorless, odorless, tasteless gas. It is a cumulative poison. Even low levels of CO have been shown to cause brain and other vital organ damage in unborn infants with no effect on the mother.
The following symptoms are related to CARBON MONOXIDE POISONING and should be discussed with ALL members of the household:
MILD EXPOSURE: Slight headache, nausea, vomiting, fatigue (often described as “flu-like” symptoms).
MEDIUM EXPOSURE: Severe throbbing headache, drowsiness, confusion, fast heart rate.
EXTREME EXPOSURE: Unconsciousness, convulsions, cardiorespiratory failure, death.
Many cases of reported CARBON MONOXIDE POISONING indicate that victims are aware they are not well, but they become so disoriented that they are unable to save themselves by either exiting the building or calling for assistance. Young children and household pets may be the first affected.
Your combination alarm is designed to detect the toxic CO fumes that result from incomplete combustion, such as those emitted from appliances, furnaces, fireplaces and auto exhaust.
What Levels of CO Cause an Alarm?
Underwriters Laboratories Inc. UL2034 defines three specific alarm points by which all residential CO alarms must alarm. They are measured in parts per million (ppm) of CO over time (in minutes).

UL2034 Required Alarm Points:

If the alarm is exposed to 400 ppm of CO, it must alarm between 4 and 15 minutes.
If the alarm is exposed to 150 ppm of CO, it must alarm between 10 and 50 minutes
If the alarm is exposed to 70 ppm of CO, it must alarm between 60 and 240 minutes.
This alarm is designed to act as a continuous monitor. It is not designed for use as a short-term testing device to perform a quick check for the presence of CO.

WHAT TO DO IF CARBON MONOXIDE IS DETECTED

WARNING!
Never ignore the alarm sound. If you hear the alarm horn sounding a continuous horn pattern of 4 beeps, 5 second pause, carbon monoxide has been detected. Evacuate everyone from the dwelling.

Never disconnect the power from the alarm to stop a nuisance alarm. Doing so will disable the alarm and remove the protection. In the case of a true unwanted alarm, use the silence feature. The silence feature is intended to temporarily silence the alarm while the problem is identified and corrected. Open a window or fan the CO away from the alarm. The alarm will reset automatically when it returns to normal operation. . The alarm will stop sounding automatically

WARNING!
Actuation of your CO Alarm indicates the presence of **carbon monoxide (CO), which can kill you.** In other words, when your CO Alarm sounds, you must not ignore it! Some individuals are more sensitive to CO than others, in-cluding people with cardiac or respiratory problems, infants, unborn babies, pregnant mothers and elderly people can be more quickly and severely affected by CO. Members of sensitive populations should consult their doctors for advice on taking additional precautions.

WARNING! IF THE CO ALARM SOUNDS:

Operate the Silence button.
Call your emergency services, fire department or 911. Write down the number of your local emergency service here: __
Immediately move to fresh air—outdoors or by an open door or window. Do a head count to check that all persons are accounted for. Do not reenter the premises or move away from the open door or window until the emergency services responder has arrived, the premises have been aired out, and your alarm remains in its normal condition.
After following steps 1-3, if the alarm reactivates within a 24 hour period, repeat steps 1-3 and call a qualified appliance technician to investigate for sources of CO from fuel-burning equipment and appliances and inspect for proper operation of this equipment. If problems are identified during this inspection, have the appliances and equipment serviced immediately.

Note any combustion equipment not inspected by the technician and consult the manufacturers’ instructions or contact the manufacturer(s) directly for more information about CO safety and this equipment. Make sure that motor vehicles are not, and have not been, operating in an attached garage or adjacent to the residence. Write down the number of a qualified appliance technician here:

NOTE: A qualified appliance technician is defined as “a company engaged in and responsible for the installation, testing, servicing, or replacement of heating, ventilation, air conditioning (HVAC) equipment, combustion appliances and equipment, gas fireplaces or other combustion equipment.”
Because carbon monoxide may dissipate by the time a first responder or investigator arrives, it may be difficult to locate the source of CO. USI Electric/Universal Security Instruments shall not be obligated to pay for or reimburse the user of this alarm for any carbon monoxide investigation or service calls. Fire departments, HVAC contractors and most utility companies will perform CO inspections. Some may charge for this service. It is advisable to inquire about any applicable fees prior to having the service performed

POTENTIAL SOURCES OF CARBON MONOXIDE

Carbon monoxide (CO) is a colorless, invisible, odorless, tasteless, poisonous gas produced when fossil fuels do not burn completely, or are exposed to heat, usually fire. This alarm is not designed to detect any other gas. This alarm will only indicate the presence of CO or smoke which reaches the sensor. Carbon monoxide and natural gas may be present in other areas.
Fossil fuels such as wood, charcoal, coal, natural gas, oil, gasoline, propane and kerosene produce CO.
Household appliances may be sources of CO and include the gas kitchen range, cook top, gas clothes dryer, heater, furnace, water heater, wood-burning stove, certain pool heaters, fireplaces and portable space heathers. When they are not properly maintained, are improperly ventilated, or malfunction, CO levels can rise quickly.
Electrical appliances typically do not produce CO.
Energy efficient homes. CO is a real danger now that homes are more “air- tight”, with added insulation, sealed windows, and other weatherproofing can trap CO inside.
Damaged or insufficient venting such as; corroded or disconnected water heaters, vent pipes, leaking chimneys, pipes or flues or cracked heat exchangers, blocked or clogged chimney openings.

Vent pipe connections improperly designed or becoming loose.
Improper use of appliances by operating a barbeque grill, using charcoal, gas or wood pellets, hibachi in an enclosed area such as a garage or screened porch.
Vehicles and portable generators operating in a garage or any area too close to the living space.
Transient CO problems also known as on-again/off-again CO problems, can be caused by outdoor conditions and other special circumstances.
Excessive spillage or reverse venting of fuel-burning appliances.
Outdoor ambient conditions and temperature inversions which can trap exhaust and pollutants close to the ground.
Wind direction or wind velocity pushing heavy air in the vent pipes back in to the dwelling.
Negative air pressure caused by simultaneous operation of multiple fuel burning appliances competing for limited internal air.

HOW CAN I PROTECT MY FAMILY FROM CO POISONING?

This alarm is an excellent means of protection. It monitors the air and sounds a loud alarm before (CO) levels become threatening to the average, healthy adult.
An alarm is not a substitute for proper maintenance of home appliances. To help prevent CO problems and reduce the risk of CO poisoning:
Clean chimneys and flues yearly. Keep them free of debris, leaves and nests for proper air flow. Have a professional check for rust and corrosion, cracks or separations. These conditions can prevent proper air movement and cause backdrafting.
Never “cap” or cover a chimney in any way that would block air flow.
Test and maintain all fuel-burning equipment annually. Many local gas or oil companies and HVAC companies offer appliance inspections for a nominal fee.
Make regular visual inspections of all fuel-burning appliances. Check appliances for excessive rust and scaling. Check the color of the flame on the burner and pilot lights to ensure they are burning properly. They should be blue. If the flame is orange or yellow, it is a sign the fuel is not burning completely and a repair technician should be contacted.
Teach every member of your home about the sounds and operation of this alarm. Proper response is key to survival.

DEVELOP AND PRACTICE A PLAN OF ESCAPE

BASICS OF ESCAPE PLAN

Make a floor plan indicating all doors and windows and at least two escape routes from each room. Second story windows may need a rope or chain ladder.
Have a family meeting and discuss your escape plan, showing everyone what to do in case of fire.
Determine a place outside your home where all of you can meet if a fire occurs.
Familiarize everyone with the sound of the smoke alarm and train them to leave your home when they hear the sound.
Identify children’s bedrooms with red stickers placed in the upper left corner of the windows. They are available from your local fire department.
Practice a fire drill at least every six months. Practice allows you to test your plan before an emergency. You may not be able to reach your children. It is important they know what to do!

WHAT TO DO WHEN THE ALARM SOUNDS

Leave immediately by your plan of escape. Every second counts, so don’t waste time getting dressed or picking up valuables.
In leaving, don’t open any inside door without first feeling its surface. If hot, or if you see smoke seeping through cracks, don’t open that door! Instead, use your alternate exit. If inside door is cool, place your shoulder against it, open it slightly and be ready to slam it shut if heat and smoke rush in.
Stay close to the floor if air is smoky. Breathe shallowly through a cloth, wet if possible.
Once outside, go to your selected meeting place and make sure everyone is there.
Call the fire department from your neighbor’s home – not from yours!
Don’t return to your home until fire officials say that it is all right to do so.
