Macurco CM-xx Operation Manual
8. The Fan Relay can be configured for latching or non-latching (default) when activated (when the gas concentration
exceeds fan relay set point). Once latched in, power will need to be interrupted or the "TEST" button pressed to un-
latch the relay condition.
9. The Fan Relay will engage if the fan setting Carbon Monoxide concentration is exceeded for longer than the Fan Relay
Delay time. Unless it is configured for latching, the fan relay will disengage once both of these conditions have been
met:
• Carbon Monoxide concentration has dropped below fan setting
• Fan Relay Run time has been exceeded
Note that the "disable" fan setting will cause the fan relay to not engage. The fan relay will engage in trouble fault
condition (if the Trouble Fan Setting Option is set to "ON") and will disengage once trouble fault condition is cleared.
10. The Current Loop is 4 mA in clean air and 4-20 mA for 0-200ppm CO
NOTE: 22 to 12 AWG wire shall be used. Wire used shall meet the temperature range of the detector i.e. 0°F to 125° F (-18°C to
52°C).
