GMxA Monitoring Station
The GMxA monitoring station accepts digital inputs from
up to four sensors to provide alarm status indication for
each channel, and a Form C (SPDT) fan actuation relay.
If any of the sensors detects CO levels above 25 ppm,
or if a fault is detected, the corresponding alarm status
indicator lights and the fan relay de-energizes (failsafe).
