Pre-action Systems Fire Alarm Check Valve

Pre-action Systems Fire Alarm Check Valve

Pre-action sprinkler systems are specialized for use in locations where accidental activation is especially undesirable, such as in museums with rare art works, manuscripts, or books; and data centers, for protection of computer equipment from accidental water discharge.

 

Pre-action systems are hybrids of wet, dry, and deluge systems, depending on the exact system goal.
