Whenever the alarm is operating, the green Power LED is illuminated
and the digital display will display “0” to indicate the unit is monitoring
for CO. If the alarm senses dangerous levels of CO, the red Alarm LED
will flash, the digital display will indicate the CO concentration in parts
per million (PPM), and the alarm will emit an audible alarm pattern.
This alarm will display a “0” if CO concentrations between 0 and 30
PPM have been detected within the last 15 seconds.
When the unit is first powered up, the digital display will show three
“eights” – indicating the alarm is in the start-up mode. The three
“eights” will remain for approximately 20 seconds. After 20 seconds,
the alarm should display “0” and begin monitoring the air for CO and
will continue to do so as long as it receives power.
