CM-E1 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 CM-E1 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.
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 CM-E1TROUBLE 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
the problem persists, your detector requires repair; contact the alarm panel installer or Macurco Tech Support
for advice. If repair is required, return the unit to Macurco to comply with warranty.
CM-E1 TESTING
The CM-E1 should be tested by pushing the TEST/RESET switch; see TEST/RESET switch in CM-E1
ERRORS section above. Normally this will be the only test required for the CM-E1 and is the recommended
way to test the unit or units after installation. All CM-E1 units are factory calibrated and 100% tested for proper
operation. The unit also has the ability to automatically self test and does so every 2 1/2 minutes. If the unit
detects an improper voltage or inoperable component it will default into Trouble mode. See CM-E1 TROUBLE
INDICATOR above. Check that the CM-E1 status indicator light is illuminated, Green continuously. If not, do
not proceed with the tests.
