2. 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:

• 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.
