RECOMMENDED LOCATION OF ALARMS

  •  Locate the first smoke alarm in the immediate area of the bedrooms. Try to protect the escape route as the bedrooms are usually farthest from an exit. If more than one sleeping area exists, locate additional smoke alarms in each sleeping area. If a hall is more than 40 feet (12 meters) long, install a smoke alarm at each end.
  •  Locate additional smoke alarms to protect any stairway as stairways act like chimneys for smoke and heat.

If more than one sleeping area exists, locate additional smoke alarms in each sleeping area. If a hall is more than 40 feet (12 meters) long, install a smoke alarm at each end.
  •  Locate additional smoke alarms to protect any stairway as stairways act like chimneys for smoke and heat.
  •  Locate at least one smoke alarm on every floor level.
  •  Locate a smoke 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 smoke 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 smoke alarm on the ceiling, locate it a minimum of 4″ (10cm) from a side wall or corner (see Diagram A).
  •  When mounting smoke 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

Existing Homes:
The NFPA requires a smoke alarm 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 in any new construction home.

Sloped Ceilings (Peaked Ceilings):
Smoke alarms or smoke detectors 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 smoke detectors 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 smoke detectors 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. Manufactured Home Construction Safety Standards, Title 24 CFR, Section 3280.208 and Section 3282. For additional protection, see Single Story Residence smoke alarm requirements/recommendations for Existing Homes and New Construction Homes.
Note: For mobile homes built before 1978, install smoke alarms on inside 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 a smoke alarm inside each bedroom and in the hallway outside each separate sleeping area.

AVOID THESE LOCATIONS

  •  the garage – products of combustion are produced when you start your vehicle.
  •  near appliances or areas where normal combustion regularly occurs (kitchens, near furnaces, gas hot water heaters). Use smoke alarms with U.S.S.T.® or photoelectric sensors, or smoke alarms with Silence Feature for these areas.
  •  in areas with high humidity, like bathrooms or areas near dishwashers or washing machines. Install at least 3 feet (0.9 meters) away from these areas.
  •  in areas of turbulent air such as air returns or heating and cooling supply vents, smoke alarms shall not be located where airflow prevents smoke from reaching the alarms.
  •  in extremely dusty, dirty or insect-infested areas. Loose particles interfere with smoke alarm operation.
  •  in areas where temperature may fall below 400F (4.40C) or rise above 1000F (37.80C).
  •  closer than 1 foot (0.3m) from fluorescent lights, electrical “noise” and flickering may affect the alarm’s operation.
  •  closer than 3 feet (0.9m) horizontal path from the tip of the blade of a ceiling suspended (paddle) fan.
  •  on a poorly insulated ceiling or exterior wall (mount smoke alarm on an inside wall).

This alarm will not work 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 battery power to operate. If the battery is dead, the alarm cannot operate. The sealed battery cannot be replaced.

Early warning fire detection is best achieved by the installation of fire detection equipment in all rooms and areas of the household as follows: A smoke alarm installed in each separate sleeping area (in the vicinity of, but outside of, the bedrooms); and, as appropriate, heat or smoke alarms in living rooms, dining rooms, kitchens, hallways, attics, furnace rooms, closets, utility storage rooms, basements and attached garages. Test the alarms weekly to assure proper operation.

HOW TO INSTALL

IMPORTANT: Read all instructions before using this product. This smoke alarm is sealed. The cover is not removable.

  1.  A mounting bracket is provided on the back of the alarm. Remove the mounting bracket from the back of the alarm by holding the mounting bracket and twisting the alarm in the direction indicated by the “TWIST TO REMOVE” arrow on the side of the alarm base.
  2.  Attach the mounting bracket in the proper location on the wall or ceiling (screws and anchors provided.
  3.  Activate the Permanent Power battery feature by removing and discarding the battery pull tab. The alarm will sound one long beep to confirm it is powered up. Once activated, the alarm cannot be turned off without permanent deactivation. The alarm will remain on for the next ten years (under normal operating conditions).
  4.  Press the Test/Silence button. The alarm will sound 3 beeps, 2-second pause, 3 beeps, and the red power LED will blink in sync with the cycle of 3 beeps and turn off.
  5.  Push and twist the alarm clockwise onto the mounting bracket.
  6.  The red LED will blink on approx. every 2 minutes to indicate proper operation.
  7.  Refer to the Locking/Tamper feature to utilize the optional alarm tamper-resistant feature.

WARNING: Failure to properly install and activate this alarm will prevent proper operation of this alarm and will prevent its response to fire hazards. Test the alarm following installation and weekly thereafter. The built-in test switch accurately tests the alarm operation as required by ANSI/UL217 Standards for Safety. If, at any time, you test the alarm and it does not perform as described, replace it immediately. CAUTION: Due to the loudness of the alarm, we suggest that you place your fingers over the sounder opening while testing your alarm. Continuous exposure to the high sound level of this alarm over an extended period of time may cause hearing loss.

OPTIONAL ALARM TAMPER-RESISTANT FEATURE:
The tamper-resistant locking feature for this model deters someone from removing the alarm from the mounting bracket. The breakaway locking pin is clearly marked and molded into the mounting bracket. Refer to Figure 1.

TO ACTIVATE THE ALARM LOCKING FEATURE:
Do not activate the locking feature until you have activated the battery, mounted the smoke alarm to the bracket and tested the smoke alarm. Refer to OPERATION, TESTING & MAINTENANCE instructions on Page 5.

  1.  Detach the breakaway alarm locking pin from the mounting bracket.
  2. Insert the pin into the hole in the side of the alarm after the alarm has been installed on the mounting plate. Refer to the diagram below for correct placement.UNIVERSAL-SECURITY-INSTRUMENTS-MI3050S-2-In-1-Smoke-and-Fire-Alarm-FIG-4

TO DEACTIVATE THE LOCKING FEATURES: To remove the smoke alarm for cleaning or servicing, you must first remove the locking pin, if it has been installed.

OPERATION, TESTING & MAINTENANCE

OPERATION:
The smoke alarm is operating once the battery power is connected by removing the pull tab. When products of combustion are sensed, the alarm sounds a loud alarm which continues until the air is cleared.
This alarm incorporates the NFPA recognized horn signal for evacuation. During alarm mode, the horn produces three beeps followed by a two-second pause and then continually repeats. READY/ACTIVE CONDITION: The red LED blinks on once approx. every 2 minutes to indicate the alarm is properly functioning.
ALARM CONDITION: The alarm emits a loud, pulsating alarm sound and the red LED blinks on in sync with the horn.

NUISANCE ALARMS: The smoke alarm is designed to minimize nuisance alarms. Smoking will not normally set off the alarm unless smoke is blown directly into the smoke alarm. Combustion particles from cooking may set off the alarm if the smoke alarm is located close to the kitchen cooking surface. Large quantities of combustion particles are generated from spills or broiling.
If the smoke alarm does sound, check for fires first. If a fire is discovered, get out and call the fire department. If no fire is present, check to see if one of the reasons listed above may have caused the alarm. Use the Silence Feature if it is a nuisance alarm, or reset the alarm by pressing and holding the Test/Silence button for ten seconds. Refer to RESET below.
NOTE : It is best to “reset” the alarms before initial test is performed. See below for Reset procedures.

TESTING: Test by pressing the Test/Silence button on the smoke alarm cover until the alarm sounds, then release. The alarm sounds if all electronic circuitry, horn and battery are working. If no alarm sounds, the alarm may have a power supply failure. Test the smoke alarm weekly to assure proper operation. IMPORTANT: Under normal conditions, the test button should sound the alarm immediately after it is pressed. There are special conditions that, when you press the Test/Silence button, you will experience a delay of approx. 10-15 seconds before the alarm sounds. This delay occurs if the Test/Silence button is pressed during a self-diagnostic period. This may occur after initial power up. Retest after 10-15 seconds.
ALARM ORIGINATION: The QUICK FIND® feature will allow you to immediately locate the originating alarm (once the alarm has stopped sounding). To initiate QUICK FIND®, press the Test/Silence button on each alarm. After releasing the button, the originating alarm will continue to sound for 60 seconds. It is necessary to test each alarm to determine the originating alarm.
RESET: To reset the QUICK FIND® Alarm Origination condition, press and hold the Test/Silence button on any alarm for at least 10 seconds and then release. This will clear alarm origination indicator. Reset after each alarm activation.
END-OF-SERVICE LIFE NOTIFICATION: A majority of home fire deaths are a result of no smoke alarms or no working smoke alarms. In addition to the “replace by date” stamped on the back of your alarm, your alarm contains a unique audible end-of-service life notification feature. When it is time to replace your alarm, which is after approximately 10 years of operation from initial power up, the alarm will sound 2 chirps approx. every 60 seconds and the red LED will blink on once approx. every 2 minutes. The alarm should be replaced immediately.

IMPORTANT CONSIDERATIONS
YOUR ALARM HAS BEEN DESIGNED WITH A PRODUCT END-OF-SERVICE LIFE WARNING 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. NOTE: NUMEROUS ALARMS OR PROLONGED ALARMING IS NOT TYPICAL AND WILL CONSUME THE BATTERY CAPACITY, SHORTENING THE LIFE OF THIS PRODUCT.

NEVER use an open flame of any kind to test this smoke alarm. You might accidentally damage or set fire to the smoke alarm or to your home. The built- in test switch accurately tests the smoke alarm’s operation as required by Underwriters Laboratories Inc. (UL).

If you choose to use an aerosol smoke product to test the smoke alarm, be certain to use one that has been Listed to Underwriters Laboratories, Inc. Safety Standards and use it only as directed. Use of non-UL Listed products or improper use of UL Listed products may affect the smoke alarm’s sensitivity.

NUISANCE ALARM SILENCE FEATURE: This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the smoke alarm. The smoke alarm Silence Feature is activated by pushing and releasing the Test/Silence button on the smoke alarm cover while in alarm condition. The smoke alarm will automatically reduce sensitivity and the red LED will blink on approx. every 10 seconds to indicate the alarm is in the Silence mode. The smoke alarm will gradually regain normal sensitivity and sound the alarm if particles of combustion are still present. The approx. 10 minute Silence feature may be used repeatedly until the air has cleared, by pushing and releasing the Test/Silence button again. Resetting the smoke alarm after a nuisance alarm is recommended.
NOTE: If the Test/Silence button is pressed and held during the Silence mode, the smoke alarm will be tested normally. Upon the release of the Test/Silence button, the Silence mode will be restarted.
Before using the alarm Silence Feature, identify the source of the smoke and be certain that safe conditions exist.

REGULAR MAINTENANCE: Test the alarm at least once per week to verify it is operating properly.
Clean this alarm at least once a month to remove dust, dirt, insects, and debris. Using a soft brush or wand attachment to a vacuum cleaner, vacuum all sides and cover a smoke alarm. Be sure all the vents are free of debris.
DO NOT use spray cleaning chemicals or insect sprays directly on or near the alarm. DO NOT paint the alarm. Doing so may permanently damage the alarm and interfere with the alarm’s ability to sense smoke. The outside can be wiped with a damp cloth. DO NOT use any household cleaning agents, solvents, or sprays including compressed gas dusters or any other chemical on or near your alarm. DO NOT disassemble or attempt to clean inside the alarm. This alarm contains no serviceable parts.
If the alarm becomes contaminated by excessive dirt or grease, and cannot be cleaned, it should be replaced immediately. Alarms have a limited life and should always be replaced 10 years from the date of purchase.
AFTER CLEANING, REINSTALL YOUR ALARM AND TEST YOUR ALARM BY USING THE TEST BUTTON

BATTERY AND ALARM DEACTIVATION
This alarm uses a sealed battery. The battery should last for approximately 10 years under normal operating conditions. The smoke alarm has a low battery indicator which is 2 chirps approx. every 60 seconds. The red LED blinks on once approx. every 2 minutes.
Due to the loud 85 decibel alarm, stand at arm’s length away from the alarm or use ear protection when testing. Weekly testing is required to ensure proper operation. Irregular or low volume sound may indicate a defective alarm and it should be returned for service. Follow instructions to prepare an alarm for shipment or disposal.

Deactivation of the alarm is permanent.
Do not attempt to open the alarm for any reason.
Place this alarm into shut-down mode at the end of its useful service life. Once the smoke alarm has entered end-of-service-life mode, it is necessary to deactivate the alarm operation. This will stop the product end-of-service-life warning signal and also discharge the remaining capacity of the battery to render it safe for disposal.

  1.  Remove the alarm from the mounting bracket by rotating it in the direction shown by the arrows on the rim of the base.
  2.  The alarm deactivation key is located in the mounting bracket of the alarm. See Figure2.
  3.  Use a small flat blade tool to remove the deactivation key (breakaway) from the mounting bracket.
  4.  Push the tip of the key into the deactivation slot (keyhole) outline on the label and insert fully.
  5.  Turn the key clockwise to the “off” position slowly until you feel the switch actuate and the key stops turning.
  6.  This will discharge the alarm battery and stop the alarm chirping after approximately one minute. The alarm is now safe for disposal.
  7.  The deactivation key cannot be removed and the alarm cannot be attached to the bracket.
  8.  Be sure to install a new alarm.

Once this alarm has been deactivated:

  •  The alarm cannot be reactivated
  •  The alarm cannot be reattached to the bracket
  •  The alarm will no longer detect smoke

REPAIRS AND SERVICES

These smoke alarms contain less than 1 microcurie (37 kilobecquerel) of Americium 241, a radioactive material. The distribution of these ionization- type smoke alarms is licensed by the U.S. Nuclear Regulatory Commission; the consumer is exempt from any licensing or requirements. If the smoke alarm is defective in any way, do not tamper with the smoke alarm. Return the smoke alarm for servicing. (See warranty for instructions or in-warranty returns.) There will be a service charge for repairing out-of-warranty smoke alarms.
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.
