WIRING/GENERAL (7139CS ONLY)

1. Use ANSI/UL listed cable with Class 1 insulation.

2. Observe local code requirements. Use box connector to anchor cable to outlet box.

3. Metal outlet boxes must be grounded to earth ground.

4. NOTICE: USE ONLY DURACELL® MN 1604 BATTERY WITH THE 7139CS SERIES

SMOKE ALARMS. AVAILABLE AT MANY RETAIL STORES.

CAUTION: Turn off electricity to prevent SHOCK and damage to smoke alarm. Be sure the

power line to device is not controlled by any on/off switch, or other type of switch, other than

a fuse or circuit breaker.

IMPORTANT: Insure that all fluorescent lighting fixtures are properly grounded or on

separate circuits.

NOTICE: THE WIRING TO BE USED SHALL BE IN ACCORDANCE WITH THE

PROVISIONS OF ARTICLE 210 OF THE NATIONAL ELECTRICAL CODE, NFPA 70. WIRE

INSTALLATION SHOULD BE PERFORMED ONLY BY A LICENSED ELECTRICIAN.

MOUNTING OUTLET BOX (7139CS ONLY)

Use a 2" x 3" switch box or a 4" square or octagon junction box. Mount a box for each

smoke alarm. If wall mounting is desired, be sure the box screws are oriented to upper right

and lower left corners. Be sure to use supplied mounting plate.

NOTICE: FOR TROUBLE AREAS WHERE THERE CAN BE A LARGE VOLUME OF AIR

BLOWING OUT THROUGH THE ELECTRICAL JUNCTION BOX. YOU MUST FIRST

ATTACH AN ADHESIVE BACKED FOAM GASKET, WHICH HAS BEEN PACKED WITH

YOUR SMOKE ALARM, TO THE BACK SIDE OF THE MOUNTING BRACKET BEFORE

IT'S SECURED TO THE JUNCTION BOX.

WIRING ONE SMOKE ALARM (7139CS ONLY)

1. Run a minimum of 16 gauge, 2-conductor cable, plus ground (3 wires) to the device

junction box from a power supply. Smoke alarms should be run on their own dedicated

circuit. Use ANSI/UL listed Class 1 wire.

NOTICE: THE WIRING TO BE USED SHALL BE IN ACCORDANCE WITH THE

PROVISIONS OF ARTICLE 300.3(B) OF THE NATIONAL ELECTRICAL CODE, NFPA 70,

AS WELL AS ARTICLE 210.

2. Make wire connections to the supplied plug-in connector as follows: black to black, white

to white, and connect the ground wire to the metal outlet box.

WHERE SMOKE ALARMS SHOULD BE PUT IN MOBILE HOMES

In mobile homes built after about 1978 that were designed and insulated to be energy-

efficient, smoke alarms should be installed as described in the section above. In older mobile

homes that have little or no insulation compared to today's standards, uninsulated metal

outside walls and roofs can transfer heat and cold from outdoors, making the air right next to

them hotter or colder than the rest of the inside air. These layers of hotter or colder air can

prevent smoke from reaching a smoke alarm. Therefore, put smoke alarms in such units

only on inside walls, not more than 12 inches (30 cm) from the ceiling. If you are not sure

about the insulation level in your mobile home, or if you notice that the walls or ceiling are

unusually hot or cold, put the smoke alarm on an inside wall.

Minimum protection requires one smoke alarm as close to the sleeping area as possible.

For better protection, put one smoke alarm in each room, but first read the "LOCATIONS TO

AVOID."

LOCATIONS TO AVOID

This smoke alarm must be installed within 16 feet of the pillow

Any location outside of 16 feet will cause this alarm to be less effective and not meet

code requirements.

Nuisance alarms are caused by placing smoke alarms where they will not operate

properly. To avoid nuisance alarms, do not place smoke alarms:

w In or near areas where combustion particles are normally present such as kitchens;

in garages where there are particles of combustion in vehicle exhausts; near furnaces,

hot water heaters, or gas space heaters. Install smoke alarms at least 20 feet

(6 meters) away from kitchens and other areas where combustion particles are

normally present.

w In air streams passing by kitchens. FIGURE 7 shows how a smoke alarm can be

exposed to combustion particles in normal air movement paths, and how to correct this

situation.

w In damp or very humid areas, or next to bathrooms with showers. The moisture

in humid air can enter sensing chamber as water vapor, then cool and condense

into droplets that cause a nuisance alarm. Install smoke alarms at least 10 feet

(3 meters) away from bathrooms.

w In very cold or very hot environments, or in unheated buildings or outdoor

rooms, where the temperature can go below or above the operating range of the

device. Temperature limits for proper operation are 40° to 100°F (4.4° to 37.8°C).

w In very dusty or dirty areas. Dust and dirt can build up on the smoke alarm's

sensing chamber and can make it overly sensitive, or block openings to the

sensing chamber and keep the smoke alarm from sensing smoke.

w Near fresh air inlets or returns or excessively drafty areas. Air conditioners,

heaters, fans, and fresh air intakes and returns can drive smoke away from smoke

alarms, making the devices less effective.

w In dead air spaces at the top of a peaked roof or in the corners between ceilings

and walls. Dead air may prevent smoke from reaching a smoke alarm.

w In insect-infested areas. If insects enter a smoke alarm's sensing chamber, they may

cause a nuisance alarm. Get rid of bugs before installing devices where bugs are a

problem.

w Near fluorescent light fixtures. Electrical "noise" from nearby fluorescent light fixtures

may cause a nuisance alarm. Install smoke alarms and fluorescent lights on

separate electrical circuits.

Never remove power from smoke alarm to silence a nuisance

alarm. Open a window or fan air around device to remove the smoke. The smoke

alarm will automatically turn off when the smoke in the air is completely gone. Do not

stand close to device. The sound produced by the smoke alarm is loud because it is

designed to awaken you in an emergency. Prolonged exposure to the horn at a close

distance may be harmful to your hearing.

NOTICE: RED-YELLOW WIRE: THE RED-YELLOW WIRE FROM THE SMOKE ALARM IS

FOR TANDEM CONNECTION ONLY. DO NOT USE, AND DO NOT REMOVE INSULATION

CAP UNLESS CONNECTING ANOTHER SMOKE ALARM.

WIRING TWO OR MORE SMOKE ALARMS (7139CS ONLY)

Tandem Installation

NOTICE: ALL SMOKE ALARMS IN TANDEM INSTALLATION MUST BE CONTROLLED

BY THE SAME FUSE OR CIRCUIT BREAKER. OTHERWISE TANDEM UNITS WILL NOT

OPERATE. TANDEM WILL OPERATE IN THE EVENT OF AC POWER FAILURE IF

BATTERY IS CONNECTED TO THE SMOKE ALARM.

LIMITATIONS: A maximum of six (6) smoke alarms of model 7139CS or models with the

relay option (F, HF, TF) may be tandem interconnected. Do not exceed 1125 feet between

first and last smoke alarm.

Wire used for interconnecting shall be in accordance with the latest edition of Article 760

of the National Electrical Code (NEC) and NFPA 70, and must not exceed a resistance of

10 ohms.
