<br />~ General
<br />U Description
<br />
<br />-_/
<br />
<br />The Central Model A Upright & Pendent
<br />Automatic Sprinklers are standard
<br />response - standard coverage, fusible
<br />solder type spray sprinklers designed for
<br />use in light, ordinary, or extra hazard,
<br />commercial occupancies such as banks,
<br />hotels, shopping malls, factories, refiner-
<br />ies, chemical plants, etc.
<br />These sprinklers are available with wax
<br />and lead coatings that may be utilized to
<br />extend the life of copper alloy sprinklers
<br />beyond that which would othenNise be
<br />obtained when exposed to corrosive
<br />atmospheres.
<br />Although wax and lead coated sprinklers
<br />have passed the standard corrosion tests
<br />of the applicable approval agencies, the
<br />testing is not representative of all possible
<br />corrosive atmospheres. Consequently, it is
<br />recommended that the end user be
<br />consulted with respect to the suitability of
<br />these corrosion resistant coatings for any
<br />given corrosive environment. The effects
<br />of ambient temperature, concentration of
<br />chemicals, and gas/chemical velocity,
<br />should be considered, as a minimum,
<br />along with the corrosive nature of the
<br />chemical to which the sprinklers will be
<br />exposed.
<br />Operation: A fusible alloy is sealed into a
<br />bronze actuating rod (center strut) by a
<br />stainless steel ball. When the alloy melts
<br />at its rated temperature, the ball is forced
<br />upward into the center strut, releasing the
<br />!\vo ejectors and operating the sprinkler.
<br />WARNING
<br />
<br />The Model A Upright & Pendent Sprin-
<br />klers described herein must be installed
<br />and maintained in compliance with this
<br />document, as well as with the applicable
<br />standards of the National Fire Protection
<br />Association, in addition to the standards of
<br />any other authorities having jurisdiction
<br />Failure to do so may impair the integrity of
<br />these devices.
<br />
