ALARM TEST TRIM

Dorot’s alarm test trim allows connecting a hydraulic water motor alarm (WMA or gong) and optional pressure switch to the main valve.

A water motor alarm is a hydraulic, automatic mechanical device, actuated by water flow and is designed to sound a continuous alarm upon actuation of a deluge, pre-action or dry-pipe valve.

The alarm test trim is connected between the upstream and downstream main valve ports and allows testing the alarm and pressure switch without opening the main valve.
