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

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 

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 

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.
