RESET/SILENCE SWITCH
The switch on the front of the CM-S1 labeled “TEST/RESET,” performs three functions.
1.) A short press of switch, less than 5 seconds long, will place the unit into self test mode with no alarm relay activation. 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, about 6 seconds long, will place the unit into self-test mode with alarm relay activation. Pressing and holding the switch
will cause the 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-S1 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.
TROUBLE INDICATOR
The CM-S1’s status LED is normally illuminated with a green color. To indicate a “trouble” condition, the CM-S1 status LED will flash
AMBER and the CM-S1 buzzer will emit a short "chirp" every 50 seconds. See ERRORS below. The CM-S1 computer continuously monitors
various detector parameters. Failure of the CM-S1’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-S1. The CM-S1 does NOT provide a trouble signal to the alarm panel.
ERRORS
The computer in the CM-S1 continuously monitors various 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 Macurco Tech Support
for advice. If repair is required, return the unit to manufacturer to comply with warranty.
MAINTENANCE
The CM-S1 should be tested monthly by pushing the TEST/RESET switch; see TEST/RESET switch, above. At the same time, the CM-S1 should be
cleaned using the soft brush attachment of your vacuum cleaner. The CM-S1 should be tested after cleaning to ensure the unit is operating normally.
There are no field calibration procedures for this unit.
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.
LIMITED WARRANTY
Aerion Technologies Inc. (ATI), manufacturer of Macurco products, warrants the CM-S1 gas detector will be free from defective materials and
workmanship for a period of five (5) years from date of manufacture (stamped on the unit), provided it is maintained and used in accordance with
