AI Customer ServiceA preaction system combines automatic sprinklers with supplemental fire detection system. Since supplemental detection is being used, the automatic control valve used in the preaction system riser is typically a deluge valve (automatic control valve); however, the piping system will have automatic sprinklers instead of open nozzles.
Since supplemental detection is being used, the automatic control valve used in the preaction system riser is typically a deluge valve (automatic control valve); however, the piping system will have automatic sprinklers instead of open nozzles. When there are more than 20 sprinklers, the sprinkler piping must be supervised with air pressure.
A pre-action sprinkler system consists of a sprinkler system and an electrical detection system with pressurised air in the sprinkler pipework and water held back by the pre-action control valve. In the event of the operation of the electrical detection system the pre-action valve operates and allows water into the sprinkler pipework.
A manual release or pull station is a normally closed, quick opening valve which acts as a system releasing device for a preaction system. This device is required by NFPA for preaction systems and is required to operate hydraulically, pneumatically or mechanically independent of the detection devices.
13.4.3.2.4 Preaction valve flow tests shall incorporate full functionality of the system as a unit, including automatic and manual activation. 13.4.3.2.5 Preaction valves protecting freezers shall be trip tested in a manner that does not introduce moisture into the piping in the freezer.
Status green LED’s show that the Valves are in their normal operating position. The “Pre Action Status” section provides indication and controls for the Pre Action valve assembly. Monitored inputs for Low Air, System Tripped, Manual Release & Auto/ Manual Status are provided.
