Kidde HD135 - Manual (Page 5)

• In an area where the temperature may fall below -20ºF or rise above 100ºF.
• Near fluorescent lights – electronic "noise" may cause nuisance alarms.
• Heat alarms are not to be used with detector guards unless the combination
(alarm and guard) have been evaluated and found suitable for that purpose.
4. 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 AC 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 or modified square wave inverter. These type 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 AC 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.
• When alarms are interconnected, all interconnected units must be powered
from a single circuit.
• A maximum of 24 Kidde/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.
