RECOMMENDED LOCATIONS FOR SMOKE ALARMS, Continued

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.

INSTALLING SMOKE ALARMS IN MOBILE HOMES &

RVS

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 insula-

tion. 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). WARNING: Test units used in

RVs after the vehicle has been in storage, before every trip, and

once a week while in use. Failure to test units used in RVs as

described may remove your protection.

This equipment should be installed in accordance with NFPA (National Fire

Protection Association) 72 and 101. National Fire Protection Association,

One Batterymarch Park, Quincy, MA 02269-9101. Additional local build-

ing and regulatory codes may apply in your area. Always check com-

pliance requirements before beginning any installation.

AGENCY PLACEMENT RECOMMENDATIONS

NFPA 72 (National Fire Code)

Smoke Alarms shall be installed in each separate sleeping room, outside

each sleeping area in the immediate vicinity of the bedrooms and on each

additional story of the family living unit, including basements and exclud-

ing crawl spaces and unfinished attics.

In new construction, Alarms shall be so arranged that operation of any one

Alarm shall cause the operation of all Alarms within the dwelling.

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 base-

ment, 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 nor-

mally recommended, as these locations occasionally experience condi-

tions that can result in improper operation.

California State Fire Marshal (CSFM)

Early warning detection is best achieved by the installation of fire detec-

tion 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.

ABOUT SMOKE ALARMS

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.

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 visu-

al 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.

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 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.

SPECIAL COMPLIANCE CONSIDERATIONS

This unit alone is not a suitable substitute for complete fire detec-

tion systems in places housing many people—like apartment build-

ings, condominiums, hotels, motels, dormitories, hospitals, long-

term health care facilities, nursing homes, day care facilities, or

group homes of any kind—even if they were once single-family

homes. It is not a suitable substitute for complete fire detection

systems in warehouses, industrial facilities, commercial buildings,

and special-purpose non-residential buildings which require special

fire detection and alarm systems. Depending on the building codes

in your area, this unit may be used to provide additional protection

in these facilities.

The following information applies to all four types of buildings listed

below:

In new construction, most building codes require the use of AC or

AC/DC powered Smoke Alarms only. AC, AC/DC, or DC powered

Smoke Alarms can be used in existing construction as specified by local

building codes. Refer to NFPA 72 (National Fire Alarm Code) and NFPA

101 (Life Safety Code), local building codes, or consult your Fire

Department for detailed fire protection requirements in buildings not

defined as "households."
