Wiring Instructions
CAUTION! Turn off the main power to the circuit 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 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.
CAUTION! Kidde alarm 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.
• 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.
