Wet alarm valve
The Loss Prevention Certification Board (LPCB part of BRE Global) sets the standards needed to ensure that fire and security products and services perform effectively. LPCB’s Loss Prevention Standards (LPS) are applied in fire and security sectors around the world.
LPS 1040 - 2.3, Requirements and testing procedures for the LPCB approval and listing of wet alarm valve sets, published by BRE Global in 2014, defines a wet alarm valve as: ‘A valve that permits flow of water into a wet sprinkler system, prevents reverse flow of water and provides for an alarm under specified flow conditions.’
A wet alarm valve set is: ‘An alarm valve assembly complete with wet alarm valve, trim and water motor alarm. Optional items, such as a retard chamber, flow meter, pressure switch and flow switch may also be included as part of the wet alarm valve set.’
