Power Up; Operation - 3M Macurco Directives D'utilisation

Power Up

When the unit is turned on it performs a self-test, which activates the audible and visual alarms. If the self-test fails,
or all the alarms do not activate, do not use. Failure to do so may adversely affect product performance and result in
sickness or death.
When the detector is first powered, the status light will alternate between RED and GREEN as the unit performs a 2-1/2
minute warm-up cycle and self-test procedure. The buzzer on the CM-E1 will cycle once, emitting its characteristic 4-chirp
tone. At the end of this 2-1/2 minute cycle, the status light will turn GREEN to indicate normal operation and safe air. The
alarm relay is not energized during the 2-1/2 minute warm-up cycle.

Operation

The CM-E1 continuously monitors the ambient air at the sensor. If the CM-E1 measures levels of CO greater than the danger
level, the RED light will turn on, the Alarm Relay will switch to actuate the alarm circuits in the control panel, and the buzzer on
CM-E1 units will sound. The CM-E1 is programmed to alarm if the danger levels of carbon monoxide are exceeded, which are
time and concentration-related. The alarm points are: 70 ppm of CO after 60 to 240 minutes, 150 ppm of CO after 10 to 50
minutes, and 400 ppm of CO after 4 to 15 minutes, in accordance with the provisions of UL Standard 2034.
