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.
