• 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) 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 intercon-
nected 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) avail-
able at all electrical supply stores and most hardware stores.
