Fire protection valves are designed for use in air conditioning systems and in addition to fire protection. These valves also have a ventilation function. It can be used for both air supply and extract applications. The volume flow rate can be adjusted via the two-position control unit. The valves are fixed into the wall with bayonet fixing and catch device to prevent accidental release.
Fire Pump is a water pump designed specifically for pumping water to sprinkler systems. The pump size is about 750-gpm capacity. They have two-stage pumps which have two impellers mounted on a single shaft. These have a capability of operating in a series mode through the use of a transfer valve. These are usually powered by an electrical motor and require the installation of an emergency generator. This pump becomes active when the pressure in the fire sprinkler system drops below a threshold. The pressure drops in the sprinkler system significantly when one or more sprinkler heads are exposed to heat above its design temperature. The sprinkler head releases and water discharges. The fire pump provides additional water pressure to the sprinkler system. These pumps are used in high-rise buildings. They are also used in warehouses and facilities that do not have adequate city water pressure.
