Installation
• 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 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, heat,
carbon monoxide, etc.) With 18 alarms interconnected,
it is still possible to interconnect up to a total of 6
remote signaling devices and/or relay modules.
IMPORTANT: Kidde alarms and accessories CAN ONLY BE interconnected
with other Kidde alarms and accessories as well as specified brands and
models of interconnect compatible alarms. Connection of Kidde products
to a non-specified manufacturer's interconnect system, or connection with
non-specified equipment from another manufacturer into an existing Kidde
system could result in nuisance alarming, failure to alarm, or damage to
one or all of the devices in the interconnect system. Refer to the User's
Guide supplied with each Kidde product for interconnect compatible
models, brands, and devices.
• When mixing models which have battery backup with
models without battery backup, be advised that the
models without battery backup will not respond during
an AC power failure.
• For more information about compatible interconnect
units and their functionality in an interconnect system,
visit our web site at: www.kidde.ca
• The maximum wire run distance between the first and
last unit in an interconnected system is 305 m (1000').
• Image 3 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 CSA listed
household wire (as required by local codes) available at
all electrical supply stores and most hardware stores.
