SentryPlus Alert Technology-Relief Valves

SentryPlus Alert® technology provides a solution for relief valve flood detection. When activated with an add-on connection kit, the flood sensor included with select relief valves can signal excessive discharge resulting from heater, expansion tank, or other equipment malfunction through a building management system (BMS). This allows for the notification of a potential flooding event or maintenance need.

The connection kit is sized for the relief valve outlet, diameters ranging from 3/4" to 2 1/2". Check the relief valve specification to verify outlet size. Connection kits include a flood sensor and activation module for new or existing installations.
