Installation
Interconnecting
This CO Alarm is interconnectable with other multiple-
station Kidde and Nighthawk products (refer to list on
page 4). It is not designed to be interconnected with any
other manufacturer's products.
• When compatible Kidde smoke alarms and heat alarms
are interconnected to your CO alarm, they will only
respond to a smoke or heat related event.
• When mixing Kidde alarms which have battery back-up
with models without battery back-up, be advised that
the models without battery back-up will not function
during an A.C. power failure.
• For alarms that are being used as single station alarms,
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.
• All interconnectable alarms should be installed on a UL
Listed or recognized junction box. All connections
should be made by a qualified electrician and must
conform to article 760 of the U.S. National Electrical
Code, NFPA 72 and/or any other codes having
jurisdiction in your area.
• The appropriate power source is 120 Volt AC Single-
Phase supplied from a non-switchable circuit, which is
not protected by a ground fault interrupter.
• 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, CO,
smoke/CO combination, heat, etc.)
