Fig. 3.8 Alarm Options
3.3.1 Levels
In this function, individual alarm setpoints can be
adjusted or disabled. If an alarm value is set to
zero (0), the alarm will be disabled.
3.3.2 Latching
In this function, individual alarms can be selected
to be LATCH or NON-LATCH. When an alarm is
latching, a tick symbol will appear. If non-latching,
the option will be blank.
Note: Latch means when a gas alarm setpoint is
exceeded, the audible and visual alarm will stay
active until the gas value returns within the gas
alarm setpoint and requires the user to press and
hold LH (INVERT) button
for one (1) second to
clear.
IMPORTANT: If the alarm is latching, the user will
not be permitted to set the mute option. If already
set, it will be automatically reset.
