Gas Challenge
Cautions:
1.
Ensure that the area around the sensor is gas free before exiting the Gas
Challenge mode.
2.
Upon leaving gas challenge mode, all outputs return to their active states (from
inhibited). Ensure that values have returned to zero to avoid extraneous alarms.
Provides the means to check correct operation of the unit in the presence of the gas being sensed
without triggering alarms, etc.
Selecting this menu item puts the Transmitter Unit's 4-20mA output into Inhibit and prevents the
relays from being energised. The Transmitter Unit does not signal Fault if one is induced.
