The model XL INST is a quick response institutional sprinkler. It is a fusible solder link type automatic sprinkler designed for standard and extended coverage applications. These sprinklers have demonstrated response times in laboratory tests which are 5 to 10 times faster than standard response sprinklers. The quick response enables model XL INST sprinklers to apply water to a fire much more quickly than standard response sprinklers of the same temperature rating. Only when the solder link melts does the operating mechanism release from the sprinkler allowing the deflector to be extended for distributing the discharging water. Modern architectural designs require sprinklers that provide not only the best fire protection, but also an attractive appearance. The model XL INST meets both criteria. The flush style of this sprinkler provides for an aesthetically pleasing installation by concealing the entire sprinkler's operating parts with the exception of the heat sensing link. The Model XL INST has been designed for use in correctional and mental health facilities and in any other type of institution where attempts by an occupant at self-injury might involve the use of a fire sprinkler. The heat sensor is designed to release a suspended load that exceeds 50 lbs. when dropped from a 1 in height. The conical escutcheon assembly is firmly attached to the sprinkler body with tamper-resistant fasteners. The horizontal sidewall model uses an escutcheon with an integral deflector shelf.
