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.
On Initiating Alarm Red LED Flashes Once per
Second
On All Other Alarms Red LED Shines Continuously
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.
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.
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 BRK Electronics® carbon
monoxide alarms CO5120B, and CO5120PDB be
interconnected.
