Product Description

The Model XL Institutional is a quick-response sprinkler with a
fusible solder link thermal element specially designed for use
in institutional applications. Standard coverage and extended
coverage models are available.
The flush style of this sprinkler conceals all operating parts
with the exception of the heat sensing link. When the solder of
the sensing link melts, the operating mechanism releases and
allows the deflector to be extended for distributing water. These
sprinklers are listed for a maximum service pressure of 175 psi
(12.0 bar).
The Model XL Institutional 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 misuse of a fire sprinkler. The heat sensor is designed
to release a suspended load that exceeds 50 lbs. when dropped
from a 1-inch 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.
Note: Misuse of or tampering with Reliable Institutional Sprinklers
which leads to property damage or personal injury, including
death, as a result of dismantling or modifying this product for use
unrelated to the intended use shall not become the responsibility
of Reliable Automatic Sprinkler Co., Inc.
