Alarm Valves
Wet and dry alarm check valves that trigger a local alarm on sprinkler system flow.
Overview
An alarm valve sits at the base of a sprinkler riser and triggers a local water-motor alarm the moment water flows — a wet system's or dry system's first line of local notification. We source wet and dry types matched to your riser configuration.
