Tyco Fire Product Star PH-5 Instruction Manual

Std. Response - Std. Coverage
Institutional Sidewall Sprinklers
Model PH-5, K=5.6

GENERAL DESCRIPTION

The Model PH-5, 5.6 K-Factor, Institutional Horizontal
Sidewall Sprinklers are standard response - standard cov-
erage, fusible solder type spray sprinklers designed for
use in light or ordinary hazard occupancy, correctional,
detention, and mental health care facilities.
The unique features of the Model PH-5 provide a tamper
resistant sprinkler design that helps eliminate the opportu-
nity for individuals to injure themselves or others with a
fire sprinkler. At the same time, the Model PH-5 optimizes
on an aesthetically appealing flush design that conceals
most of the operating parts.
The Model PH-5 Horizontal Sidewall Sprinklers are de-
signed for installation along a wall or the side of a beam
and just beneath a smooth ceiling. They are commonly
used instead of pendent sprinklers because of building
construction considerations where piping above the ceil-
ing is not desirable.

WARNINGS

The Model PH-5 Sprinklers described herein must be in-
stalled and maintained in compliance with this document,
as well as with the applicable standards of the National
Fire Protection Association, in addition to the standards
of any other authorities having jurisdiction. Failure to do
so may impair the integrity of these devices.
The owner is responsible for maintaining their fire protec-
tion system and devices in proper operating condition.
The installing contractor or sprinkler manufacturer should
be contacted relative to any questions.

OPERATION

In the standby condition, the design of the Model PH-5 is
such that a suspended load of 80 lbs. (36 kg) or more ap-
plied to the linkage mechanism will release the sprinkler.
Also, when properly installed, the escutcheon is held fast
to the wall to deter removal of the escutcheon. The shape
of the escutcheon cannot easily be grasped, which fur-
ther deters tampering.
A fusible solder operating element secures the linkage
mechanism of the Model PH-5. When the rated tempera-
ture is reached, the solder melts to release the linkage
mechanism holding the sprinkler closed, which then al-
lows the sprinkler to activate by allowing the deflector to
extend outward, and water to flow.
