In dusty areas. Dust particles may cause nuisance alarm or failure to alarm.
In very humid areas (greater than 85% R.H.). Moisture or steam can cause
nuisance alarms.
In insect-infested areas.
Smoke alarms should not be installed within 3 ft (.9m) of the following: the
door to a kitchen, the door to a bathroom containing a tub or shower, forced
air supply ducts used for heating or cooling, ceiling or whole house ventilating
fans, or other high air flow areas.
Kitchens. Normal cooking may cause nuisance alarms. If a kitchen alarm is
desired, it should have an alarm silence feature or be a photoelectric type.

3. INSTALLATION INSTRUCTIONS
WIRING REQUIREMENTS
This smoke alarm should be installed on a U.L. listed or recognized junction
box. All connections should be made by a qualified electrician and all wiring
used shall be in accordance with articles 210 and 300.3(B) of the U.S. National
Electrical Code ANSI/NFPA 70, NFPA 72 and/or any other codes having jurisdic-
tion in your area. The multiple station interconnect wiring to the alarms must
be run in the same raceway or cable as the AC power wiring. In addition, the
resistance of the interconnect wiring shall be a maximum of 10 ohms.
The appropriate power source is 120 Volt A.C. Single Phase supplied from a
non-switchable circuit which is not protected by a ground fault interrupter.
WARNING: This alarm cannot be operated from power derived from a square
wave, modified square wave or modified sine wave inverters. These types of
inverters are sometimes used to supply power to the structure in off grid
installations, such as solar or wind derived power sources. These power
sources produce high peak voltages that will damage the alarm.
WIRING INSTRUCTIONS FOR A.C. QUICK CONNECT HARNESS
CAUTION! TURN OFF THE MAIN POWER TO THE CIRCUIT BEFORE WIRING
THE ALARM.
For alarms 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.
