Air Maintenance Device that automatically maintains air pressure within a manual pre-set limit dependent on desired system pressure of the dry pipe sprinkler system.
The BT 5900 Series Alarm Check Valves are designed for use in wet pipe automatic sprinkler fire protection systems. The valve automatically operates electrical and/or hydraulic alarm devices when a sustained flow of water occurs within the system. An integrated retard chamber helps minimize unwanted alarms caused by pressure fluctuations or water surges. BT Alarm Check Valves are suitable for…
The Dry Alarm Valve is designed for use in dry pipe sprinkler systems installed in areas where temperatures may fall below freezing. It acts as a water flow alarm device, allowing water to enter the sprinkler system only when the system is activated, helping to prevent water from freezing in the pipework.
The Dry Accelerator is a quick-opening device designed to reduce the operating time of dry pipe sprinkler systems. It detects a rapid drop in system air pressure and quickly releases air from the actuator, allowing the sprinkler control valve to open faster. Installed on the air supply trim at the inlet of the dry actuator, the Dry Accelerator remains closed…
