Todd, I know of no other sprinklers beside the Viking Coin or Tyco CC1/CC2 to protect to CPVC pipe. Would the FM accept if a sign was installed on the doors stating that "no storage" is allowed instead of sprinklers? I think your safe with CPVC pipe in this space. You can run pipe listed for light hazard occupancies to be installed in ordinary hazard rooms of otherwise light hazard occupancies where the room does not exceed 400 sq. ft.(NFPA 13 (02ed)6.3.6.2)and page 18 of the BlazeMaster hand book.

This is an NFPA 13R system using CPVC pipe in concealed spaces. The Fire Marshal has requested that sprinklers be added in the space over the bathroom and kitchen ceilings. The space contains air handling units (no fuel). The FM's concern is that the access panel to get to the units would allow the tenants to store things in there. The space is wood construction and is approximately 20 ft long, 7 ft wide and 4.5 ft high. There is CPVC pipe running through the space. The Blazemaster spec states that sprinklers specifically listed for use with CPVC pipe shall be used in combustible concealed spaces with their product. The only sprinklers I can find that are listed for this use are COIN sprinklers (Viking, Tyco). Since this space is over 3 ft high, COIN's would not necessarily be required, per NFPA 13. Is there a non-COIN sprinkler that is listed for protecting CPVC? I haven't been able to find one. Also, if this is area is to be considered accessible for storage, then can CPVC pipe be in this space at all? Also, I don't believe the COIN sprinklers can be used in a space that is considered occupied, n'est pas? Obviously, this building has already been piped and this is an after-the-fact request by the FM. Thoughts? Todd G.
