6.Model KN-COPP-B-LPM (with digital display)

Operating Characteristics

When the unit is first powered up, the green Operate LED flashes once every 30 seconds and the digital display will show three “eights”

–indicating the alarm is in the start-up mode. The three “eights” will remain for approximately 30 seconds. Then, the alarm will display “0” and begin monitoring the air for CO and will continue to do so as long as it receives power.

This alarm will display a “0” if CO concentrations between 0 and 30 PPM have been detected within the last 15 seconds.
