INTERCONNECTING MULTIPLE
CO ALARMS
Interconnecting Multiple CO Alarms
Interconnected units can provide earlier warning
of a CO problem than stand-alone units,
especially if the problem starts in a remote area
of the dwelling. If any unit in the series senses
CO, all units will alarm. To determine which CO
alarm initiated an alarm, refer to the table:
All wiring must conform to all local electrical
codes and Article 760 of the National Electrical
Code. Refer to NFPA, Chapter 2 and/or your
local building code for further connection
requirements.
WARNING!
AC and AC/DC CO alarms can be
interconnected. Under AC power, all units will
alarm when one senses CO. When power is
interrupted, only the AC/DC units in the series
will continue to send and receive signals.
AC powered CO alarms will not operate.
IMPORTANT!
Interconnect units within a single family residence
only. Otherwise all households will experience
unwanted alarms when you test any unit in the
series. Interconnected units will only work if they are
wired to compatible units and all requirements are
met. It is recommended only
