GX4 GAS MONITOR
ALARMS
The alarm will sound in the following
scenarios:
Concentration of any gas being monitored
exceeds the allowable limits set by the
cartridge
Software becomes unresponsive
Air supply is lost
Cartridge is missing
Battery is low
The screen will display which gas and
cartridge is detecting the alarm. Also, the
light above the affected slot on the screen will
turn red.
The alarm can be silenced by pressing the
"Silence" hot key button under the screen.
This will silence the alarm for 30 seconds.
If the gas concentration is still above the
allowable limit the alarm will sound again.
All alarms and silence events are recorded in
the event logs.
It is recommended that an external alarm
system be wired to the Auxiliary outlet.
CARTRIDGE REMOVAL
Upon removal of a cartridge, a warning
message will appear on the screen. If a
response to this warning is not made within
30 seconds, the alarm will sound. This is a
safety feature to detect a cartridge coming
out of the unit unintentionally.

failure.
Under normal operation the monitor can run
for up to 24 hours on battery power.
