Alarm Retest Delay (SS3)
SS3 selects the alarm retest delay, the setting in which an alarm is
latched and retested every hour.
OFF = Non-latching (default)
ON = Latching-retest each hour
ON = Latching-retest each hour
The factory default is OFF=Non-latching. If SS3=ON and a leak is
detected, the alarm condition is latched, the sensor goes into a “sleep”
mode and power to the leak detection cable is discontinued. After one
hour, the sensor will automatically retest if the leak is still present. If
the leak has cleared itself, the sensor deactivates the alarm, resets
itself and resumes normal operation; if the leak is still present, the
alarm condition remains activated and the sensor goes to “sleep” and
retests in another hour. This procedure will repeat indefinitely until
the leak is cleared or until the alarm is manually reset.
A manual reset can be initiated at any time. If the leak condition has
A manual reset can be initiated at any time. If the leak condition has
not yet cleared, the sensor re-alarms after the selected leak detect fil-
ter delay; if the leak has cleared, the sensor deactivates the alarm and
resets itself. SS3 is disabled if SS2=ON.
The factory default settings of SS2=OFF and SS3=OFF place the
The factory default settings of SS2=OFF and SS3=OFF place the
sensor in a non-latching, continuous retest mode. The sensor does not
go to “sleep” after detecting a leak—instead, it continually checks to
determine whether the leak condition has cleared itself. Alarms auto-
matically reset when the leak condition clears. Initiating a manual
reset will cause the sensor to trigger the alarm again after the selected
leak detect filter delay. The leak detect cable remains powered at all
times.
