Abstract
A sprinkler backflow alert system includes a sprinkler system, a building fire panel, a backflow preventor including at least one shut-off valve, a fluid detection system, and a tamper switch. The backflow preventor may be fluidly coupled upstream of the sprinkler system. The fluid detection system is configured to detect a discharge of water from the backflow preventor and generate a water discharge signal corresponding to the backflow discharge. The tamper switch is configured to detect a change in a position of the at least one shut-off valve and generate a tamper signal in the event the at least one shut-off valve is closed or partially closed. When a backflow discharge event occurs, a signal is sent to the fire panel triggering the building fire alarm as well as sending an alert to the local fire department and facility owner.
