fire detection systems, so if one unit senses smoke, all units alarm. Interconnected units may provide earlier warning than
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.
Smoke alarms 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, or fires caused by violent explosions resulting from escaping gas.
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.
It is recommended you replace a smoke alarm after 10 years from date of manufacture. See back of smoke alarm for manufacture date.

INSTALLING SMOKE ALARMS IN SINGLE-FAMILY RESIDENCES
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.
Interconnected AC powered units for the hearing impaired. 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.

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

INSTALLING SMOKE ALARMS IN MOBILE HOMES
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).
AGENCY PLACEMENT RECOMMENDATIONS
IMPORTANT!
This equipment should be installed in accordance with the National Fire Protection Association’s Standard 72. National Fire Protection Association, One Batterymarch Park, Quincy, MA
NFPA Standard 72 Section 2-2.1.1.1
2.5.2.1Smoke
California State Fire Marshall
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.
