Ken, I diidn't see any replies, so I'll give you what I think.  I think you 
will find them under heat detectors for releasing service.  Probably that makes 
them part of the deluge system.  The manufacturer's literature should give you 
better info.

Subject: heat activated devices for a deluge system.


Are heat actuated devices (HADS) used to initiate a deluge system via a
pneumatic signal considered:
1- a heat detector and so the required testing is per NFPA 72 ?
2- or are the HADS considered part of the deluge system so testing
requirements as per NFPA 25 ?

Thanks
