We specified Raven sprinklers for a racquetball court recently. We hit a sprinkler directly with different objects like a souvenir mini-bat and a piece of 1/4" metal strap, then pumped it up to 200 and left it over night. I am convinced that this particular sprinkler is WAY more resistant to physical damage than a residential concealer.

Features: The RAVEN assembly increases . the difficulty of tampering with the sprinkler that may cause a false activation. The tamper resistant nature of the . RAVEN helps reduce the opportunity for individuals to injure themselves or others with components of a fire sprinkler. The RAVEN optimizes an aesthetic. cally appealing flush design that conceals all of the operating parts. Nowhere does it say that "This device is less susceptible to being damaged by tampering" in fact it has this big disclaimer: Tyco Fire Suppression & Building Products specifically disclaims any liability for damages or injury (including death) arising out of or caused by manipulation, dismantling, or misuse of RAVEN Sprinklers or the use or attempted use of the RAVEN Sprinklers or any component thereof as an instrument unrelated to its intended function as a fire protection device. Since Chris is our resident "AT HOME TEST CENTER" I'll bet that if you fire a paint ball at the Raven from 6' away three times, and a concealed res head three times, that the res head will still operate in a fire, whereas the Raven may not. A far more likely scenario for a frat house. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Steve Leyton Sent: Wednesday, November 10, 2010 9:55 AM To: [email protected] Subject: RE: QR sprinklers in R2 occupancy The problem with institutional sprinklers is the cost - what's a Raven, $25 on the street? But if you look at it as a one-time first cost of insurance, it's a cheap upgrade. Concealers will settle, and the gap between plate and ceiling can expand if the sprinklers aren't "touched up". When struck, the plates can be destroyed in one hit; they're as subject to damage as an exposed sprinkler and likely to not be replaced. And get roll-painted once every two years or so if they're still in place. In a frat house, which can't be THAT big a project (100 pendents?), I'd go with institutional sprinklers hands down.
