This Carbon Monoxide Relay Module can be used to activate auxiliary warning devices such as external bells and sirens, hallway or stairwell lighting. It provides isolated, (no internal connection to 120 volts AC) normally open, and normally closed contacts.
This relay module is only activated by a Kidde Carbon Monoxide Alarm interconnect signal. And will only activate when it receives a CO interconnect signal from a compatible device. When in the activated mode (as a result of a CO signal), this device will deactivate if it receives a smoke interconnect signal from a compatible device.
