The KCO-R is a two-stage CO sensor with a relay output for each stage. There are three status LEDs: amber for warning, red for alarm, and red/green for microprocessor status.

If the CO level rises above the warning stage setpoint for over 30 seconds, the warning relay, amber warning LED, and a three-minute minimum 'on' timer will activate. Once below the set point, the relay and LED will reset. If the concentration continues to rise and exceeds the alarm stage set point for 10 minutes, the alarm stage relay and red LED will activate.

The KCO-R has a two-color LED to indicate its operating status. After the sensor stabilizes, the LED flashes green, indicating operation is normal and not in alarm. When the LED is flashing red, the unit is sensing CO above its warning (50 ppm standard) setting. A continuous red or green indicates a failure of the unit. The LEDs are off during power failure.
