Series C400-FS, C500-FS, and LFC500-FS are each equipped 

with an integrated flood sensor that detects excessive relief valve 

discharges and triggers notification of potential flood events. 

NOTICE

An add-on connection kit is required to activate the integrated 

flood sensor. Without the connection kit, the flood sensor is a 

passive component and will not communicate with any other de-

vice. (A retrofit sensor connection kit is also available for existing 

installations. See “Add-on and Retrofit Sensor Connection Kits,” 

for ordering details.)
