Mount the Activation Module
Set SW1 DIP switch on the activation module by the wet threshold table below
then attach the module to the flood sensor.
DIP switches on the 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 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.
NOTICE
The wet threshold value must be set by backflow valve size.
1. Use the #2 Phillips screwdriver to detach the four screws
on the activation module to remove the cover.
