Install the Flood Sensor and Activation Module
The activation module receives a signal from the 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. Set the assembly for attachment of the flood sensor to the
rim of the relief valve body, beneath the relief valve outlet.
3. Tighten the sensor to the relief valve body.
5. Press the activation module onto the sensor.
2. Thread the #2 Phillips screwdriver through the sensor
adapter to the captive screw and align the sensor with
the rim attachment point.
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.
