ALARM CONFIGURATION
Note: Non-latch means that when a gas alarm
setpoint is exceeded, the audible and visual alarm
will re-set automatically when the gas value returns
within the gas alarm setpoint.
3.3.3 Mute
This function allows certain alarms to be
programmed thus allowing the user to acknowledge
a gas alarm and silence the AUDIBLE alarm for a
period of 60 seconds. During this period, the
VISUAL alarm stays active during the presence of
gas. After 60 seconds has elapsed, the AUDIBLE
alarm will sound again to alert the user that the
gas hazard still exists if gas is still present. Also, if
gas level has dropped within limits but alarm is
latching, it will sound again.
If during the MUTE period a different alarm occurs,
the instrument will respond as normal, depending
on the alarm configuration.
3.4 LEL ALARMS
The LEL sensor alarm setpoints are displayed as shown
in Fig. 3.8:
