Install the Flood Sensor and Sensor Activation Module
Attach the flood sensor and the sensor activation module to the backflow relief valve. For assemblies
with the integrated flood sensor, start at step 4.
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.
Custom Flood Sensor Settings
The default settings on the sensor activation module for detecting discharge are
suitable for the assembly series. However, the DIP switches can customized for
a different wet threshold and time delay. Scan the QR code for more information.
1. Remove the bolts from the flood sensor.
3. Insert the bolts and tighten.
5. Press the sensor activation module onto the sensor.
2. Position the two halves of the sensor on the relief valve.
4. Remove the dust cover from the sensor.
6. Check that the module is fully seated to seal the O-ring and
to make electrical contact.
NOTICE
Retain the dust cover to protect the flood sensor when the
activation module needs to be removed or replaced.
