Reset/Silence Switch - 3M Macurco Directives D'utilisation

The CM-E1 will automatically come out of alarm once the air clears. The time to stop alarming will depend on the CO
exposure time and the CO level.

Reset/Silence Switch

The switch on the front of the CM-E1 labeled "TEST/RESET," performs three functions.
1.) A short press of switch, less than 5 seconds, will place the unit into self test mode with no alarm relay activation. The
buzzer will sound for two complete alarm cycles, the status light will turn red for 5 seconds and then it will alternate
slowly between green and amber while the self-test executes. The controlling software simulates a 3000 ppm CO
environment and causes the unit to alarm after approximately one minute has elapsed. When this happens, the status
light turns red and the buzzer will sound two complete alarm cycles. The unit will then return to normal operation.
2.) A long press of switch, 5 or more seconds long, will place the unit into self-test mode with alarm relay activation.
Pressing and holding the switch will cause the buzzer to sound for two complete alarm cycles and status light to
turn red for 5 seconds and then switch to solid amber. The alarm relay will then be activated and the switch can be
released. After about 5 seconds, the alarm relay will turn off and the status light will alternate slowly between green
and amber while the self test executes. The controlling software simulates a 3000 ppm CO environment and causes
the unit to alarm after approximately one minute has elapsed. When this happens, the status light turns red and the
buzzer will sound two complete alarm cycles. The unit will then return to normal operation.
3.) If the CM-E1 is in an alarm condition due to the detection of carbon monoxide, one push of the switch will cause the
alarm buzzer to mute for five minutes. After the five-minute period, if CO is still present, the status light will again
switch to RED, the alarm relay will close and the buzzer will sound. If after the five-minute period, the detected CO level
has dropped below 70 ppm, the CM-E1 unit will reset.
