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 interconnect- ed 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 inter- connect up to a total of 6 remote signaling devices and/or relay modules.

•When mixing models which have battery backup (1275, 1276, 1285, 1296, i12040, i12060, i12080, PE120, PI2000, KN- COSM-IB, HD135F, KN-COB-IC, KN-COP-IC, RF-SM-ACDC) with models without battery backup, (1235, i12020, KN-COSM-I, 120X, SM120X, CO120X, SL177i) be advised that the models without battery backup will not respond during an AC power failure.

•The maximum wire run distance between the first and last unit in an interconnected system is 1000 feet.

•Figure 4 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.
