Horizontal Sidewall Fire Sprinkler Head, Quick Response, 1/2 in, 5.6 K, 155 deg F, White

Reliable® models F1FR56 QREC and F1FR56 QREC recessed sprinklers are quick response sprinklers which combine the durability for a standard sprinkler with the attractive low profile of a decorative sprinkler. The models F1FR56 QREC and F1FR56 QREC recessed automatic sprinklers utilize a 3 mm frangible glass bulb. These sprinklers have demonstrated response times in laboratory tests which are five times faster than standard response sprinklers. This quick response enables these sprinklers to apply water to a fire faster than standard response sprinklers of the same temperature rating. Model F1FR56 QREC quick response extended coverage concealed sprinkler is an attractive, low profile concealed sprinkler assembly. This sprinkler assembly utilizes a model F1FR56 QREC pendent sprinkler in a model CCP cup and push-on thread-off cover plate assembly. The cup is securely factory threaded on the sprinklers inlet end. The assembly is shipped with a protective cap. The sprinkler and cup are easily installed into the sprinkler fitting using the model GFR2 sprinkler Wrench. The cover plate assembly is attached to the sprinkler cup using a flexible tooth threaded engagement. The cover plate is attached to the skirt using 135 deg F (57 deg C) ordinary temperature classification solder. When the ceiling temperature rises, the solder holding the cover plate melts, allowing the release of this part and thus exposing the model F1FR56 QREC sprinkler inside to the rising ambient temperature. The temperature rating of the sprinkler identified by the color of the glass bulb. The glass bulb consists of an accurately controlled amount of special fluid hermetically sealed inside a precisely manufactured glass capsule. This glass bulb is specially constructed to provide fast thermal response.
