LOCATIONS TO AVOID

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

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

· 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. In-

stall alarms at least 20 feet (6 meters) away from kitchens and other

areas where combustion particles are normally present.

· In air streams passing by kitchens. Figure 6 shows how an alarm can

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

to correct this situation.

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

sure the power line to the alarms 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.

WARNING: Alarm installation must conform to the electrical codes in your

area and to Article 760 of the U.S. National Electrical Code. Wire installation
should be performed only by a licensed electrician.

MOUNTING OUTLET BOX

Use a 2” x 3” switch box or a 4” square or octagon junction box. Mount a box

for each alarm. If wall mounting is desired, be sure the box screws are ori-

ented to upper right and lower left corners. Be sure to use supplied Mounting

Plate.

NOTE: 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 packaged with your alarm, to the back side of the
mounting bracket before it is secured to the junction box.

WIRING ONE ALARM

1.

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

the alarm junction box from a power supply. Use UL Listed Class 1 wire.

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 box.

WIRING TWO OR MORE ALARMS

Tandem Installation

CAUTION: All alarms in a tandem installation must be controlled by the

same fuse or circuit breaker. Otherwise tandem units will not operate. Tan-

dem will operate in the event of AC power failure if battery is connected to the

alarm.

NOTE: A maximum of six (6) alarms may be tandem interconnected.

Figure 6

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

moisture in humid air can enter the sensing chamber as water vapor, then

cool and condense into droplets that cause a nuisance alarm. Install alarms

at least 10 feet (3 meters) away from bathrooms.

· In very cold or very hot environments, or in unheated buildings or

outdoor rooms, where the temperature can go below or above the operat-

ing range of the alarm. Temperature limits for proper operation are 40

°

to

100

°

F (4.4

°

to 37.8

°

C).

· In very dusty or dirty areas. Dust and dirt can build up on the alarm’s

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

sensing chamber and keep the alarm from sensing smoke.

· Near fresh air inlets or returns or excessively drafty areas. Air condi-

tioners, heaters, fans, and fresh air intakes and returns can drive smoke

away from smoke alarms, making the alarms less effective.

· In dead air spaces at the top of a peaked roof or in the corners be-

tween ceilings and walls. Dead air may prevent smoke from reaching an

alarm. See Figures 4 and 5 for recommended mounting locations.

· In insect-infested areas. If insects enter an alarm’s sensing chamber,

they may cause a nuisance alarm. Get rid of the bugs before installing

alarms where bugs are a problem.

· Near fluorescent light fixtures. Electrical “noise” from nearby fluorescent

light fixtures may cause a nuisance alarm. Install alarms at least 5 feet

(1.5 meters) away from such light fixtures.

WARNING: Never remove power from the alarm to silence a nuisance alarm.

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

alarm will automatically turn off when the smoke in the air is completely gone.

Do not stand close to the alarm. The sound produced by the 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.

BATTERY INSTALLATION

1. Remove alarm from mounting plate by turning counterclockwise.

2. Remove AC power connector and unsnap power leads from the top of the

old battery. Snap new battery onto snaps and reinsert battery through hole

in the back of the alarm. WARNING: Units with battery back-up will not

provide power or transmit an alarm to AC only units in the event of an AC

power failure. All battery backup units in tandem with good batteries will

operate normally during an AC power failure.*

*Strobe will not operate during AC power failure.

WIRING/GENERAL

1. Use 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. Use only Duracell MN 1604 or Eveready 522 battery with the 517TCSB

Series smoke alarms.

NOTE/RED-YELLOW WIRE: The red-yellow wire from the alarm

is for tandem connection only. DO NOT USE, AND DO NOT RE-

MOVE INSULATION CAP UNLESS CONNECTING ANOTHER

ALARM.
