RC-1 RC-1 type delay-Delay is installed in the water pressure fluctuations (such as a public water supply system) wet system, prevent the water system pressure fluctuations caused false alarms. When the nozzle valve plant operation, stable continuous flow of water into the sprinkler system pipe network, wet alarm valve plate to open the valve, the water flows from the throttle valve alarm port inlet orifice assembly (pore size 5.6mm), part of the water flows from the throttle Components outlet orifice (aperture 3.2mm) out of the rest of the water injection to the delay chamber. After the delay cavity filled, out of the water so that the water alarm and / or water pressure alarm switch action, as long as the valve plate open, the alarm will continue until the valve plate is closed. AMD-1 pressure-pressure maintenance device AMD-2 Air Compressor controlled pressure maintenance device AMD-1 type pressure-pressure to maintain the pressure regulator unit with field adjustable for pre-action system, dry system or deluge system, preaction system pressure dry pipe network control start. AMD-1 using compressed air in place of stainless steel valves, such as an air compressor with a pressure tank, factory air, nitrogen gas with a pressure regulator valve plastic bottles, air pressure must be higher than the pressure in the pipe system requirements. AMD-1 is used in place of the central company D-2, GEM companies F324 and S460 STAR company pressure maintenance device. AMD-2 type air compressor-controlled pressure maintenance device with a field adjustable pressure switch for pre-action system, dry system or deluge system, pressure control system pre-action dry pipe network boot. Air compressor without pressure tank supporting the use, by the pressure switch on / off control of the air compressor on / off, to maintain the pressure in the pipe network setting range. AMD-2 is used in place of the central company DU-2, GEM companies F326 and S465 STAR company pressure maintenance device.
