2.LOCATIONS TO AVOID
Alarms
must not
be located within 3 feet of the following:
• Supply and return registers used for forced air heating and air conditioning.
•Ceiling fans and other high air flow areas.
•Bathrooms which contain a tub or shower.
In general, alarms should not be located:
•In the garage. Products of combustion are present when you start your automobile.
•In an area where the temperature may fall below 40ºF or rise above 100ºF.
•In dusty areas. Dust particles may cause nuisance alarms or failure to alarm.
•In very humid areas or near a bathroom. Moisture or steam can cause nuisance alarms.
• Near fluorescent lights. Electronic “noise” may cause nuisance alarms.
3.INSTALLATION INSTRUCTIONS
WIRING REQUIREMENTS
• This smoke alarm should be installed on a U.L. listed or recognized junction box. All connec-
tions should be made by a qualified electrician and must conform to article 760 of the U.S.
National Electrical Code, NFPA 72 and/or any other codes having jurisdiction in your area.
• The appropriate power source is 120 Volt A.C. Single Phase supplied from a non-switchable cir-
cuit which is not protected by a ground fault interrupter.
WIRING INSTRUCTIONS FOR A.C. QUICK CONNECT HARNESS
CAUTION! TURN OFF THE MAIN POWER TO THE CIRCUIT BEFORE WIRING THE ALARM.
• For units that are used as single station, DO NOT CONNECT THE RED WIRE TO ANYTHING.
Leave the red wire insulating cap in place to make certain that the red wire cannot contact any
metal parts or the electrical box.
•When alarms are interconnected, all interconnected units must be powered from a single circuit.
•A maximum of 24 Lifesaver devices may be interconnected in a multiple station arrangement.
The interconnect system should not exceed the NFPA interconnect limit of 12 smoke alarms
and/or 18 alarms total (smoke, heat, carbon monoxide, etc.) With 18 alarms interconnected, it is
still possible to interconnect up to a total of 6 remote signaling devices and/or relay modules.
•When mixing models which have battery backup (1275, 1275H, 1285, HD135F) with models
without battery backup (1235, 120X, SL177i, FYCO 31) be advised that the models without bat-
tery backup will not respond during an AC power failure.
• The maximum wire run distance between the first and last unit in an interconnected system is
1000 feet.
•Figure 1 illustrates interconnection wiring. Improper connection will result in damage to the
alarm, failure to operate, or a shock hazard.
•Make certain alarms are wired to a continuous (non-switched) power line. NOTE: Use standard
UL listed household wire (18 gauge or larger as required by local codes) available at all electri-
cal supply stores and most hardware stores.

BATTERY INSTALLATION
See MAINTENANCE (Section 6) for battery installation.
CAUTION! IF THE BATTERY REMINDER FINGER IS NOT HELD DOWN IN THE BATTERY
COMPARTMENT BY THE BATTERY,THE BATTERY DOOR WILL NOT CLOSE,THE A.C. QUICK
CONNECTOR WILL NOT ATTACH TO THE DETECTOR, AND THE DETECTOR WILL NOT ATTACH
TO THE TRIM RING (SEE SECTION 6,FIGURE 6).
MOUNTING INSTRUCTIONS
CAUTION:THIS UNIT IS SEALED. THE COVER IS NOT REMOVABLE!
1. Remove the trim ring from the back of the alarm by holding the trim ring and twisting the alarm
in the direction indicated by the “OFF” arrow on the alarm cover.
2. After selecting the proper smoke alarm location as described in Section 1 and wiring the A.C.
QUICK CONNECT harness as described in the WIRING INSTRUCTIONS, attach the trim ring to
the electrical box (see Figure 2).
3. Use a screwdriver to punch out only the pair of holes in the trim ring that match your type of
electrical box or plaster ring. Mount the trim ring to the electrical box, using the appropriate
holes. NOTE: Use the circle, square and octagon markings near each mounting hole in the trim
ring to help you select the correct mounting holes (see Figure 2).
4. Pull the A.C. QUICK CONNECTOR through the center hole in the trim ring and mount the ring,
making sure that the mounting screws are positioned in the small ends of the keyholes before
tightening the screws (see Figure 2).
5. Plug the A.C. QUICK CONNECTOR into the back of the alarm (see Figure 3), making sure that
the locks on the connector snap into place. Then push the excess wire back into the electrical
box through the hole in the center of the trim ring.
6. If you have finished all the WIRING, BATTERY INSTALLATION AND TRIM RING MOUNTING
STEPS, you can install the alarm on the trim ring. Alignment marks are provided on the side of
the alarm and on the trim ring (see Figure 4).
7. Install the alarm on the trim ring with the indicating marks aligned and rotate the alarm in the
direction of the “ON” arrow on the cover until the alarm snaps in place (see Figure 4).
