WIRING INSTRUCTIONS FOR AC 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 detector,
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).
• The following models can be interconnected using the standard AC
wiring interconnect: i12020CA, i12020ACA, i12040CA, i12040ACA,
i12060CA, i12060ACA, i12010SCA, i12010SCOCA, KN-SMFM-I-CA,
KN-COB-ICB-CA, KN-COSM-IBCA, KN-COB-IC-CA, KN-COSM-ICA,
KN-COP-IC-CA, KN-COPE-ICA, P12040CA, Pi2000CA, Pi2010CA,
SM120X, CO120X, SLED177iCA, P4010ACLEDSCA.
• The maximum wire run distance between the first and last unit in an
interconnected system is 305 m (1000’).
