Rev. E | 2014.10 GEM-II - Operation Manual
Upon application of power, the green LED light indicator(s) will illuminate and the LED between
Sen-1 & Sen-2 will be blinking but all alarms are disabled for 2 minutes for a system warm up
period. After the warm up period, the system may exhibit gas alarm condition(s) if one or both
of the sensors has not completely stabilized during the warm up period. This is normal and the
length of time the gas alarms exist is dependent upon the length of time since the unit was last
powered up and the state of the environment it is installed in. After warm up, only the green
power LED(s) illuminate indicating normal operation and the relays are energized indicating
normal “Fail-safe” status.
