Trouble Indicator; Errors - 3M Macurco Directives D'utilisation

Do not cover or obstruct audible alarm opening or visual alarm LED. Doing so may adversely affect product performance
and result in sickness or death.

Trouble Indicator

Internal failure of the CM-E1 will cause an open circuit in the normally closed (NC) Trouble Relay to provide for actuation
of the control panel circuits. The status LED will flash AMBER and the CM-E1 buzzer will emit a short "chirp" every 50
seconds. See ERRORS below. The CM-E1 microprocessor continuously monitors various detector parameters. Failure
of the CM-E1's internal power supply or a lack of power to the detector will result in the status light remaining OFF (not
illuminated). In this case, the most common cause of detector trouble would be a break in the wiring between the control
panel and the CM-E1.

Errors

The CM-E1 continuously monitors various internal operating parameters. If a problem is found, the unit will switch to
Trouble mode. See TROUBLE INDICATOR above. To reset the unit for normal operation, press the TEST/RESET switch, or
remove power to the unit, wait a few seconds, then re-apply unit power. If this problem persists, your detector requires
repair; contact the alarm panel installer or 3M Macurco Tech Support for advice. If repair is required, return the unit to
manufacturer to comply with warranty.
