User Manual

Seven years after the CM-E1 is installed the end-of-life signal will be activated indicating that the CM-E1 has reached the

end of its service life and needs to be replaced. The end-of-life signal will cause an open circuit in the normally closed

(NC) Trouble Relay to provide actuation of the signal circuits. The status LED will flash alternate AMBER and OFF every

2 seconds and the CM-E1 buzzer will emit a short "chirp" every 50 seconds. The end-of-life buzzer can be silenced for 48

hours by pressing the "TEST/RESET" button. The silencing of the buzzer also resets the Trouble Relay to the Normally

Closed (NC) position. The silence function will continue to be available for 29 days after the CM-E1 initiates an end-of-life

signal. After this 29 day period the CM-E1 can no longer be silenced and must be replaced.

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 section. 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 Macurco Tech Support for advice. If repair is required, return the unit

to manufacturer to comply with warranty.

MAINTENANCE

Do not disassemble unit or attempt to repair or modify any component of this detector. This detector contains no user serviceable

parts, and substitution of components may adversely affect product performance and result in sickness or death.

The CM-E1 has a highly linear electrochemical sensor. The CM-E1 has an expiry function associated with the

installation date which will cause the unit to indicate “end-of-life” when the sensor has expired. See section "End-

of-life Indicator"

All maintenance and repair of products manufactured by Macurco are to be performed at the

Macurco Service Center. Macurco does not sanction any third-party repair facilities.

TESTING

The CM-E1 should be tested monthly by pushing the TEST/RESET switch; see TEST/RESET switch section.

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 minute cycle. If the unit detects an improper voltage

or inoperable component it will default into Trouble mode. See TROUBLE INDICATOR section. Check that the

CM-E1 status indicator light is illuminated, (GREEN) continuously. If not, do not proceed with the tests. Though

there is no field calibration procedure for this unit, there is an optional field test procedure.

CLEANING

The CM-E1 should be cleaned using the soft brush attachment of your vacuum cleaner. The CM-E1 should be tested

after cleaning to ensure the unit is operating normally.

SENSOR POISONS

The gas sensor in the detector is designed with extreme sensitivity to the environment. As a result, the CO

sensor may be damaged if it is exposed to a direct spray from aerosols such as paints, silicone vapors, etc., or

to a high density of corrosive gases such as hydrogen sulfide or sulfur dioxide for an extended period of time.

The sensor may react to chemicals such as ammoniated cleaning agents, volatile solvents and hydrogen gas.

In sufficient concentration, these chemicals may cause a false alarm.

CAUTION: This detector will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present

in other areas. Accommodation spaces should be well ventilated when household cleaning supplies or similar contaminants are used.
