Monitor relief valve discharge with smart and connected
sensor technology to detect flooding and transmit notification.
The BMS Sensor Connection Kit activates the flood sensor,
enabling functions that detect flood conditions. When excessive
relief valve discharge occurs, the flood sensor energizes a
relay signaling flood detection and triggers real-time notification
of potential flood conditions through the building management
system, or BMS.

  • Page 5: Mount The Sensor Activation Module

    The sensor 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. NOTICE The wet threshold value must be set to 50 to detect dis- charges higher than 3 gpm.
