NOTICE
Install the Flood Sensor and Activation Module
Attach the flood sensor and the activation module to the backflow relief valve. The 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 BMS
input terminal.
Custom Flood Sensor Settings
The default settings on the 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.
2. Position the two halves of the sensor on the relief valve.
B. Activation module with an 8' 4-conductor cable
C. 24V DC power adapter
D. Ground wire
