Once in a safe area, or the gas reading has returned within
the preset limits, press and hold the Right Hand (RH) button
to mute the alarm sounder and extinguish the gas
LED’s.
4.3 MUTE ALARMS
If configured, a muted alarm will be silenced for 60 seconds.
Mute ‘disabled’ cannot silence the alarm until gas falls below
the alarm level.
If alarm configuration allows muting of audible alarm, the
following applies:
Non-latching: Once alarm has been muted, the audible alarm
is cancelled for a period of 60 seconds, and if gas
concentration during that time falls below alarm set point, the
visual alarm clears automatically.
