Mount the Sensor Activation Module
Set SW1 DIP switch on the sensor activation module by the wet threshold table
below then attach the module to the flood sensor.
DIP switches on the sensor activation module can be used to specify the wet
threshold (sensitivity to water discharge) through SW1 and the timer delay (duration
before alarm) through SW2. Scan the QR code for more information.
The sensor activation module receives a signal from the flood sensor when a discharge is detected. If the
discharge meets the conditions of a qualifying event, the normally open contact is closed to provide a
signal to the Cellular Gateway input terminal.
The wet threshold value
must
be set by backflow valve size.
NOTICE
1. Use the #2 Phillips screwdriver to detach the four screws
on the sensor activation module to remove the cover.
2. Locate the valve size in the following table then use an
instrument with a pointed tip to slide the SW1 switches to
the positions noted for that size. The wet threshold option
values range from 40 (default) to 55 (most sensitive).
