When electric fans or lights are recessed in the ceiling space we don't sprinkler an otherwise non-combustible concealed space. At least I don't. Please correct me, as maybe I've been making a mistake. But if it is correct, and a fire starts from the electrical unit, the damage from the fire above the sprinklered space can be severe. Whereas, if the elect. unit is in a separate unsprinklered compartment below the sprinkler head it should be less severe.
So I'm confused. Not that it makes any difference :) Tony -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steve Leyton Sent: July 30, 2007 10:11 AM To: [email protected] Subject: RE: Fan Coil Enclosure in dwelling unit Sure, but it also contains an obvious potential source of ignition. An earlier question was asked about penetrations of the envelope in which the FCU's are located; is it a rated space and are penetrations fire sealed? Or is this potential source of ignition essentially embedded in a wall? NFPA 13R 2007 now offers some especially detailed direction, in this regard and it also underscores the difference(s) between 13 and 13R. If this were a 13R design, it would be another story, but I don't there's any doubt that the intent of 13 is to protect these spaces. Is this more or less hazardous than a linen closet or pantry? Who knows, but it's blurry enough to install a sprinkler and move along, eh?
