The Manning GM-1 is designed for long life and high
reliability. Honeywell Analytics recommends
checking signal voltages monthly and logging them
on the data sheet included with your Manning GM-1.
Additionally, the sensor being monitored should be
exposed to the target gas on a monthly basis while
all alarm functions are verified at the Manning GM-1.
This will test the sensor and any equipment con-
nected to the relays in addition to the Manning GM-1.
