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 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.). This Smoke/CO combination alarm
must be counted as a smoke alarm when determining the
number of units on an interconnect line. With 18 alarms
interconnected, it is still possible to interconnect up to a total
of 6 remote signaling devices and /or relay modules (see page
15 for details on interconnecting Kidde devices).
• The maximum wire run distance between the first and last unit
in an interconnected system is 1000 feet.
