System Installation
A typical installation of the BERMAD model 400Y-7DM, features automatic actuation via a URV pilot control valve opening in response to a fall in pneumatic pressure of the dry sprinkler pipeline and the simultaneous opening of a 2-Way solenoid triggered electrically by a signal from a fire & gas control system.
An inline check valve and drip check valve create an intermediate vented chamber to ensure against flooding when the valve is closed.
When fitted with a limit switch the valve can send a feedback signal to a remote valve status monitoring system.
