994RPDA-OSY-GPM with Flood Sensor
Series 994 and 994RPDA each include a flood sensor that detects
excessive relief valve discharges and triggers notification of potential
flood events.

An add-on connection kit is required to activate the flood sensor.
Without the connection kit, the flood sensor is a passive component
that does not communicate with any other device. (A retrofit sensor
connection kit is also available for existing installations. See "Add-on
and Retrofit Sensor Connection Kits," for ordering details.)

Use of the flood sensor does not replace the need to comply with all

Watts is not responsible for the failure of alerts due to connectivity
