5.4. Gas Alarm Options
5.4.1 Latching/Non Latching
Alarms are individually programmable to be either latching or non-latching:
• Latching - alarms can only be reset once gas readings have returned to a safe level. To
reset, press and hold the AL ACK button.
• Non-Latching - alarms will automatically reset when the gas readings have returned to a
safe level.
Note: Alarms are only available in Leak Test and Confined Space modes. By
default, Leak Test mode has all the alarm set-points in the table of
Default Set-Points
of Gas Alarms
disabled.
