Firex Smoke Alarm i4618 - Manual (Page 7)

• A maximum of 24 Kidde and/or FireX devices may be interconnected in a mul-
tiple 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 possi-
ble to interconnect up to a total of 6 remote signaling devices and/or relay
modules.
• When mixing models which have battery backup (i12040, i12060, i12080,
i4618, 1275, 1276, 1285, 1296, PE120, PI2000, KN-COSM-IB, RF-SM-ACDC,
HD135F, KN-COB-IC, KN-COP-IC) with models without battery backup, (i1220,
1235, KN-COSM-I, KN-COB-ICB, KN-COP-ICB, 120X, SM120X,CO120X,
SL177i) be advised that the models without battery backup will not respond
during an AC power failure.

ality in an interconnect system, visit our web site at: www.Kidde.com
• The maximum wire run distance between the first and last unit in an intercon-
nected system is 1000 feet.
• Figure 5 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.
