wiring instructions for aC quick Connector 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 hardwire interconnected, all interconnected units must be powered from a single circuit.
•
A maximum of 24 Kidde Safety 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, CO, Smoke/ CO Combination, heat, etc.). With 18 alarms interconnected, it is still possible to
interconnect up to a total of 6 remote signaling devices and/or relay modules (see below for details on
interconnecting Kidde devices).
•
Figure 9-B 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 (as required by local codes) available at all electrical
supply stores and most hardware stores.
