nect 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, i12040A, i12060, i12060A, i12080, i12080A, i4618, i4618A, PE120,
P12040, PI2000, PI2010, KN-COPE-i, KN-SM-FM-i, KN-COSM-IB,
KN-COSM-IBA, HD135F, KN-COB-IC, KN-COP-IC, i12010S, i12010SCO,
RF-SM-ACDC) with models without battery backup, (1235, i12020, i12020A,
KN-COSM-I,120X, SM120X, CO120X, SL177i, SLED177i) 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.
