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.

 

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.

 

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, or fires caused by violent explosions resulting from escaping gas.

 

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.

 

The unit should be replaced immediately if it is not operating properly. 

It is recommended you replace a smoke alarm after 10 years from date of manufacture. See back of smoke alarm 
for manufacture date.

 

The intensity of the strobe light 
gradually lessens as the angle 
increases. In other words, the light 
is brightest directly in front of the 
strobe light and is progressively 
less bright to either side. As 
required by Underwriters 
Laboratories Inc. (UL), the 
following illustrations show how the strobe light is dispersed. Use them to help you choose where to locate units 
for the hearing impaired.

 

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˚C) and 100˚F (38˚C). 
Make sure no door or other obstruction could keep smoke from reaching the smoke alarms.

 

Minimum coverage is one unit on every level of 

the home, plus one unit inside each bedroom/sleeping areas and in the hallway between them. For additional 
protection, additional units should be installed in family rooms, dens, or other rooms your family uses often.

More specifically, install smoke alarms:

•

On every level of your home, including finished attics and basements.

•

Inside every bedroom, especially if people sleep with the door partly or completely closed.

•

In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit in each. 
If a hall is more than 40 feet long (12 meters), install a unit at each end.

•

At the top of the first-to-second floor stairway, and at the bottom of the basement stairway.

 

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. If you install AC or AC/DC units, 
it is recommended they be interconnected for added protection.

 

For minimum security install one smoke alarm as close to each sleeping area as possible. For more security, put 
one unit in each room. Many older mobile homes (especially those built before 1978) have little or no insulation. 
If your mobile home is not well insulated, or if you are unsure of the amount of insulation, it is important to install 
units on inside walls only. Smoke alarms should be installed where temperatures normally remain between 40˚F 
(4˚C) and 100˚F (38˚C).

 

This equipment should be installed in accordance with the National Fire Protection Association’s Standard 72.

2-2.1.1.1 Smoke alarms shall be installed outside of each separate sleeping area in the immediate vicinity of the 
bedrooms and on each additional story of the family living unit, including basements and excluding crawl spaces 
and unfinished attics. In new construction a smoke alarm shall also be installed in each sleeping room. Chapter 2 
also reads as follows: 2-2.2.1: In new construction, where more than one smoke alarm is required by 2-2.1, alarms 
shall be so arranged that operation of any one alarm shall cause the operation of all alarms within the dwelling. A-
2.5.2.1 Smoke Detection-Are More Smoke Alarms Desirable? The required number of smoke alarms might not 
provide reliable early warning protection for those areas separated by a door from the areas protected by the 
required smoke alarms. For this reason, it is recommended that the householder consider the use of additional 
smoke alarms for those areas for increased protection. The additional areas include the basement, bedrooms, 
dining room, furnace room, utility room, and hallways not protected by the required smoke alarms. The installation 
of smoke alarms in kitchens, attics (finished or unfinished), or garages is not normally recommended, as these 
locations occasionally experience conditions that can result in improper operation.

 

Early warning 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, but outside 
bedrooms), and heat or smoke alarms in the living rooms, dining rooms, bedrooms, kitchens, hallways, finished 
attics, furnace rooms, closets, utility and storage rooms, basements, and attached garages.
