Product Information

Product Name: Smoke Alarm
Model: SMI100
Power Source: Battery Operated

Product Usage Instructions

Introduction:
The Smoke Alarm is designed for marine or RV use.

About Smoke Alarms:

Battery (DC) operated Smoke Alarms provide protection even during power failures, as long as fresh batteries are correctly installed. They are easy to install and do not require professional installation. However, they do not offer interconnected functionality.
AC powered Smoke Alarms can be interconnected, so if one unit detects smoke, all units will sound the alarm. However, they do not operate during power failures.
AC with battery (DC) back-up Smoke Alarms will operate during power failures, as long as fresh batteries are correctly installed. These units must be installed by a qualified electrician.
Smoke Alarms for Solar or wind energy users and battery backup power systems should only be operated with true or pure sine wave inverters. Using other types of inverters may damage the Alarm. Consult with the manufacturer if unsure about your inverter or UPS type.
Special purpose Smoke Alarms for the hearing impaired should be installed. These units include both visual and audible alarms, meeting the requirements of the Americans with Disabilities Act. They can also be interconnected.
Smoke Alarms should not be used with detector guards unless the combination has been evaluated and found suitable.
Ionization technology is more sensitive to small particles produced by flaming fires, while photoelectric technology is more sensitive to large particles produced by smoldering fires. For maximum protection, it is recommended to use both types of Smoke Alarms on each level and in every bedroom.

Installation:
Specific requirements for Smoke Alarm installation may vary. Check with your local Fire Department for current requirements in your area. It is recommended to interconnect AC or AC/DC units for added protection.

Recommended Placement:

Smoke Alarm: One on every level and in every bedroom
Carbon Monoxide Alarm: One on every level and in every bedroom
Fire Extinguisher: One on every level, plus kitchen and garage

Where Not to Install This Alarm:
For best performance, avoid installing Smoke Alarms in the following areas: [Specify areas where Smoke Alarms should not be installed]

ABOUT SMOKE ALARMS

TYPES OF ALARMS
All these Smoke Alarms are designed to provide early warning of fires if located, installed and cared for as described in the user’s manual, and if smoke reaches the Alarm. If you are unsure which type of unit to install, refer to NFPA (National Fire Protection Association) 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National Fire Protection Association, One Batterymarch Park, Quincy, MA 02269-9101. Local building codes may also require specific units in new construction or in different areas of the home.

Battery (DC) operated Smoke Alarms: Provide protection even when electricity fails, provided the batteries are fresh and correctly installed. Units are easy to install, and do not require professional installation. They do not, however, provide interconnected functionality.
AC powered Smoke Alarms: Can be interconnected so if one unit senses smoke, all units Alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided the batteries are fresh and correctly installed. AC and AC/DC units must be installed by a qualified electrician.
Smoke Alarms for Solar or wind energy users and battery backup power systems: AC powered Smoke Alarms should only be operated with true or pure sine wave inverters. Operating this Smoke Alarm with most battery powered UPS (uninterruptible power supply) products or square wave or “quasi sine wave” inverters will damage the Alarm. If you are not sure about your inverter or UPS type, please consult with the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke Alarms should be installed for the hearing impaired. They include a visual Alarm and an audible Alarm horn, and meet the requirements of the Americans with Disabilities Act. These units can be interconnected so if one unit senses smoke, all units Alarm. Smoke Alarms are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.

All First Alert® Smoke Alarms conform to regulatory requirements, including UL217 and are designed to detect particles of combustion. Smoke particles of varying number and size are produced in all fires.

Ionization technology is generally more sensitive than photoelectric technology at detecting small particles, which tend to be produced in greater amounts by flaming fires, which consume combustible materials rapidly and spread quickly. Sources of these fires may include paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles, which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.

For maximum protection, use both types of Smoke Alarms on each level and in every bedroom of your home.

INSTALLATION

WHERE TO INSTALL THIS ALARM
The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC powered and interconnected. See “Agency Placement Recommendations” for details. For additional coverage, it is recommended that you install a Smoke Alarm in all rooms, halls, storage areas, finished attics, and basements, where temperatures normally remain between 40˚ F (4.4˚ C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the Smoke Alarms.

IN GENERAL, INSTALL SMOKE ALARMS:

On every level of your home, including finished attics and basements.
Inside every bedroom, especially if people sleep with doors closed.
In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit in each. If a hall is over 40 feet (12 meters) long, install an Alarm at each end.
At the top of the first-to-second level stairway, and at bottom of basement stairway.

IMPORTANT!
Specific requirements for Smoke Alarm installation vary from state to state and from region to region. Check with your local Fire Department for current requirements in your area. It is recommended AC or AC/DC units be interconnected for added protection.

WHERE NOT TO INSTALL THIS ALARM
FOR BEST PERFORMANCE, IT IS RECOMMENDED YOU AVOID INSTALLING SMOKE ALARMS IN THESE AREAS:

Where combustion particles are produced. Combustion particles form when something burns. Areas to avoid include poorly ventilated kitchens, garages, and furnace rooms. Keep units at least 20 feet (6 meters) from the sources of combustion particles (stove, furnace, water heater, space heater) if possible. In areas where a 20-foot (6-meter) distance is not possible – in modular, mobile, or smaller homes, for example – it is recommended the Smoke Alarm be placed as far from these fuel-burning sources as possible. The placement recommendations are intended to keep these Alarms at a reasonable distance from a fuel-burning source, and thus reduce “unwanted” Alarms. Unwanted Alarms can occur if a Smoke Alarm is placed directly next to a fuel-burning source. Ventilate these areas as much as possible.
In air streams near kitchens. Air currents can draw cooking smoke into the sensing chamber of a Smoke Alarm near the kitchen.
In very damp, humid or steamy areas, or directly near bathrooms with showers. Keep units at least 10 feet (3 meters) away from showers, saunas, dishwashers, etc.
Where the temperatures are regularly below 40˚ F (4.4˚ C) or above 100˚ F (37.8˚ C), including unheated buildings, outdoor rooms, porches, or unfinished attics or basements.
In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the stove or range. Keep laundry room Smoke Alarms free of dust or lint.
Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow smoke away from the unit, preventing it from reaching the sensing chamber.
In insect infested areas. Insects can clog openings to the sensing chamber and cause unwanted Alarms.
Less than 12 inches (305mm) away from fluorescent lights. Electrical “noise” can interfere with the sensor.
In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching the Smoke Alarm.

AVOIDING DEAD AIR SPACES

“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To avoid dead air spaces, follow the installation recommendations below.
On ceilings, install Smoke Alarms as close to the center of the ceiling as possible. If this is not possible, install the Smoke Alarm at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke Alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first Smoke Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional Smoke Alarms may be required depending on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for details on requirements for sloped or peaked ceilings.

HOW TO INSTALL THIS ALARM

This unit is designed to be mounted on the ceiling, or on the wall if necessary.
Tools you will need: pencil, drill with 3/16″ (5 mm) drill bit, standard flathead screwdriver, hammer.

FIRE SAFETY TIPS
Follow safety rules and prevent hazardous situations:

Use smoking materials properly. Never smoke in bed.
Keep matches or lighters away from children;
Store flammable materials in proper containers;
Keep electrical appliances in good condition and don’t overload electrical circuits
Keep stoves, barbecue grills, fireplaces and chimneys grease- and debris-free;
Never leave anything cooking on the stove unattended
Keep portable heaters and open flames, like candles, away from flammable materials;
Don’t let rubbish accumulate. Keep Alarms clean, and test them weekly. Replace Alarms immediately if they are not working properly. Smoke Alarms that do not work cannot alert you to a fire. Keep at least one working fire extinguisher on every level, and an additional one in the kitchen. Have fire escape ladders or other reliable means of escape from an upper level in case stairs are blocked;
Have an escape plan and practice it regularly.

IF THIS SMOKE ALARM SOUNDS

RESPONDING TO AN ALARM
During an Alarm, you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.

WARNING!

If the unit Alarms get everyone out of the house immediately.
If the unit Alarms and you are not testing the unit, it is warning you of a potentially dangerous situation that requires your immediate attention. NEVER ignore any Alarm. Ignoring the Alarm may result in injury or death.
Never remove the batteries from a battery operated Smoke Alarm to stop an unwanted Alarm (caused by cooking smoke, etc.). Removing batteries disables the Alarm so it cannot sense smoke, and removes your protection. Instead open a window or fan the smoke away from the unit. The Alarm will reset automatically.

WHAT TO DO IN CASE OF FIRE

Don’t panic; stay calm. Follow your family escape plan.
Get out of the house as quickly as possible. Don’t stop to get dressed or collect anything.
Feel doors with the back of your hand before opening them. If a door is cool, open it slowly. Don’t open a hot door. Keep doors and windows closed, unless you must escape through them.
Cover your nose and mouth with a cloth (preferably damp). Take short, shallow breaths.
Meet at your planned meeting place outside your home, and do a head count to make sure everybody got out safely.
Call the Fire Department as soon as possible from outside. Give your address, then your name.
Never go back inside a burning building for any reason.
Contact your Fire Department for ideas on making your home safer.

WARNING!
Alarms have various limitations. See “General Limitations of Smoke Alarms” for details.

USING THE SILENCE FEATURES

The Silence Feature can temporarily quiet an unwanted Alarm for up to 15 minutes. To use this feature, press the “Test/Silence” button. The Alarm remains functional. The LED will flash 3 times every few seconds (for up to 15 minutes) to remind you the Alarm has been silenced. The flashing LED will stop when the unit returns to normal operation..

WARNING!
The Silence Feature does not disable the unit—it makes it temporarily less sensitive to smoke. For your safety, if smoke around the unit is dense enough to suggest a potentially dangerous situation, the unit will stay in Alarm or may re-Alarm quickly. If you do not know the source of the smoke, do not assume it is an unwanted Alarm. Not responding to an Alarm can result in property loss, injury, or death. If the unit will not silence and no heavy smoke is present, or if it stays in silence mode continuously, it should be replaced immediately.

SILENCING THE LOW BATTERY WARNING
This Silence Feature can temporarily quiet the Low Battery Warning “chirp”. Press the Test/Silence button on the Alarm. The Green light flashes normally, once every minute, during Low Battery Warning silence. After time, the low battery “chirp” will resume. Replace the battery immediately.

SILENCING THE END OF LIFE SIGNAL

This Silence Feature can temporarily quiet the End of Life warning “chirp” for up to 2 days. You can silence the End of Life warning “chirp” by pressing the Test/Silence button. The horn will chirp, acknowledging that the End of Life Silence Feature has been activated.
After approximately 2 days, the End of Life “chirp” will resume. The timer shall not be able to be reset after 14 days following the initial end-of-life signal.

IF YOU SUSPECT A PROBLEM

Smoke Alarms may not operate properly because of a dead, missing or weak batteries, a build-up of dirt, dust or grease on the Smoke Alarm cover, or installation in an improper location.
Clean the Smoke Alarm as described in “Regular Maintenance” and install fresh batteries, then test the Smoke Alarm again. If it fails to test properly when you use the test button, or if the problem persists, replace the Smoke Alarm immediately.
If you hear 3 or 5 chirps every minute or so, replace the Smoke Alarm.
If you experience frequent non-emergency Alarms (like those caused by cooking smoke), try relocating the Smoke Alarm.
If the Alarm sounds when no smoke is visible, try cleaning or relocating the Smoke Alarm. The cover may be dirty.

Do not try fixing the Alarm yourself — this will void your warranty!
If the Smoke Alarm is still not operating properly, and it is still under warranty, please see “How to Obtain Warranty Service” in the Limited Warranty.

GENERAL LIMITATIONS OF SMOKE ALARMS

Smoke Alarms have played a key role in reducing deaths resulting from home fires worldwide. However, like any warning device, Smoke Alarms can only work if they are properly located, installed, and maintained, and if smoke reaches them. They are not foolproof.
Smoke Alarms may not waken all individuals. Practice the escape plan at least twice a year, making sure that everyone is involved – from kids to grandparents. Allow children to master fire escape planning and practice before holding a fire drill at night when they are sleeping. If children or others do not readily waken to the sound of the Smoke Alarm, or if there are infants or family members with mobility limitations, make sure that someone is assigned to assist them in fire drill and in the event of an emergency. It is recommended that you hold a fire drill while family members are sleeping in order to determine their response to the sound of the Smoke Alarm while sleeping and to determine whether they may need assistance in the event of an emergency.
Smoke Alarms cannot work without power. Battery operated units cannot work if the batteries are missing, disconnected or dead, if the wrong type of batteries are used, or if the batteries are not installed correctly. AC units cannot work if the AC power is cut off for any reason (open fuse or circuit breaker, failure along a power line or at a power station, electrical fire that burns the electrical wires, etc.). If you are concerned about the limitations of battery or AC power, install both types of units.
Smoke Alarms cannot detect fires if the smoke does not reach the Alarms. Smoke from fires in chimneys or walls, on roofs, or on the other side of closed doors may not reach the sensing chamber and set off the Alarm. That is why one unit should be installed inside each bedroom or sleeping area—especially if bedroom or sleeping area doors are closed at night—and in the hallway between them.
Smoke Alarms may not detect fire on another level or area of the home. For example, a stand-alone unit on the second level may not detect smoke from a basement fire until the fire spreads. This may not give you enough time to escape safely. That is why recommended minimum protection is at least one unit in every sleeping area, and every bedroom on every level of your home. Even with a unit on every level, stand-alone units may not provide as much protection as interconnected units, especially if the fire starts in a remote area. Some safety experts recommend installing interconnected AC powered units with battery back-up (see “About Smoke Alarms”) or professional fire detection systems, so if one unit senses smoke, all units Alarm. Interconnected units may provide earlier warning than stand-alone units since all units Alarm when one detects smoke.
Smoke Alarms may not be heard. Though the Alarm horn in this unit meets or exceeds current standards, it may not be heard if: 1) the unit is located outside a closed or partially closed door, 2) residents recently consumed alcohol or drugs, 3) the Alarm is drowned out by noise from stereo, TV, traffic, air conditioner or other appliances, 4) residents are hearing impaired or sound sleepers.
Special purpose units, like those with visual and audible Alarms, should be installed for hearing impaired residents.
The Alarm may not have time to Alarm before the fire itself causes damage, injury, or death, since smoke from some fires may not reach the unit immediately. Examples of this include persons smoking in bed, children playing with matches, when a person’s clothing catches fire while cooking, fires caused by violent explosions resulting from escaping gas, or incendiary fires where the fire grows so rapidly that an occupant’s egress is blocked even with properly located Smoke Alarms.
Smoke Alarms are not foolproof. Like any electronic device, Smoke Alarms are made of components that can wear out or fail at any time. You must test the unit weekly to ensure your continued protection. Smoke Alarms cannot prevent or extinguish fires. They are not a substitute for property or life insurance.
Smoke Alarms have a limited life. The unit should be replaced immediately if it is not operating properly. You should always replace a Smoke Alarm after 10 years from date of purchase. Write the purchase date on the space provided on back of unit.
