If service is being carried out on the system or the
user does not require a local audible alarm then it can
be muted using the key switch. In the default position,
the audible alarm is enabled. In the other position, the
audible alarm is off/muted.
NOTE: The key switch can also be used to turn off the local
audible alarm during bump tests.
4.10. Resetting High Alarms (Dual-Level Units Only)
The red pushbutton on the controller is used to
acknowledge (reset) high alarms. Once the unit goes
into a high alarm state the alarm latches. After the
gas has cleared the reset button must be pushed to
clear the alarm(s).
