Kidde Combination Smoke and Carbon Monoxide Alarm KN-OOSM-IB - Manual (Page 13)

Step 2
Wiring Instructions:
WIRING REQUIREMENTS
• This smoke alarm should be installed on a U.L. listed or rec-
ognized 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
jurisdiction 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.
• Smoke alarms are not to be used with detector guards unless
the combination (alarm and detector guard) have been evalu-
ated and found suitable for that purpose.
• WARNING: The alarm cannot be operated from power
derived from a square wave, modified square wave or modi-
fied sine wave, inverter. These types of inverters are some-
times used to supply power to the structure in off grid instal-
lations, 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.
