Features
Digital Display
The continuous digital display shows you the level of carbon monoxide (if any) the
unit is sensing. The unit updates the digital display every 15 seconds .
Note:
If the unit does not sense any CO, the reading is zero (0). In most homes,
the unit reads “0” all the time. Areading of “0” is expected under normal conditions.
The blinking dot after the number shows the unit is operating.
Test/Reset Button
The Test/Reset button has three functions:
1. Press this button to test the unit weekly (see page 16 for further
details).
2. Press this button to silence the alarm. This will reset the unit and it
will then start monitoring for CO. If the CO concentration is above 70
ppm the alarm will again sound within 6 minutes.
3. Press the Test/Reset button to reset peak level memory. (See page
19).
Peak Level Button
By pressing this button, you can see the peak CO level recorded by
the alarm since it was last cleared or unplugged. This Carrier feature
allows you (or a heating contractor or a fireman) to see exactly how
serious the CO problem you have so you can react accordingly.
Sensor
The sensor is a highly sensitive, electrochemical sensor that is CO-
specific to help avoid false alarms.
Sounder Alarm
This is the loud 85 decibel pulsing alarm that will sound to alert you to
a potential problem. An alarm condition is 4 quick “chirps” – followed
by 5 seconds of silence – followed by 4 quick “chirps”. This pattern
repeats until the alarm is silenced or a high level of CO is no longer
present.
Caution:
Continuous exposure to this sound level at close range
over an extended period of time may cause hearing loss. We recom-
mend you cover the sounder with your finger or thumb while testing
the alarm.
Keyholes
When the alarm is mounted to the wall, the keyholes slide onto the
screws mounted in the wall.
