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.
