5. Alarm Characteristics
Carbon Monoxide Alarm Indicator
When the alarm senses a dangerous level of CO, the unit will emit a
loud alarm pattern. The alarm pattern is 4 quick beeps followed by 5
seconds of silence. This cycle repeats as long as a dangerous CO
conditions exist. The red Alarm LED will flash the same pattern (and the
PPM will be displayed on alarms with digital displays).
WARNING: When powered by battery backup only; after four
minutes, the alarm will sound and flash only once every minute, until
the alarm is reset or the CO is eliminated.
If the battery is low or missing, or if the unit malfunctions, it will display
other readings (and alarm differently) to alert you of specific conditions.
Please familiarize yourself, and other family members, to the difference
between a CO reading and and indication signifying a problem with the
unit itself.
WARNING: If at any time you test the alarm and it does not
perform as described, have it replaced immediately.
Whenever the alarm is operating, the digital display will display “0” to
indicate the unit is monitoring for CO. If the alarm senses dangerous levels of
CO, 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.
