Product Description
The F1S5 Series Glass Bulb Sprinkler combines the
durability of a standard sprinkler with the attractive low profile
of a decorative sprinkler. Whether installed on exposed piping
or in an office ceiling, it is functional and attractive.
Beautifully versatile is the description for the Reliable Model
F1S5 Series Recessed glass bulb sprinkler. Recessing the
F1S5 Series enhances its already low profile decorative
appearance and facilitates a rapid and perfect installation.
Model F1S5 Series Recessed escutcheon is highly
adjustable. The two piece construction makes field
installation a very easy and rapid task. This also allows ceiling
panels to later be removed without shutting down the fire
protection system, thus facilitating maintenance of above
ceiling services.

The F1S5 Series Automatic Sprinkler utilizes a special
response 5.0 mm frangible glass bulb. The glass bulb
consists of an accurately controlled amount of special fluid
hermetically sealed inside of a precisely manufactured glass
capsule. This glass bulb is specially constructed to provide
fast thermal response.
At normal temperatures, the glass bulb contains the fluid
in both the liquid phase and in the vapor phase. The vapor
phase can be seen as a small bubble. As heat is applied, the
Pendent ConventionalUpright
liquid expands forcing the bubble smaller and smaller as the
liquid pressure increases. Continued heating forces the liquid
to push out against the bulb, causing the glass to shatter,
opening the waterway and allowing the deflector to distribute
the discharging water.
The F1S5 Series Sprinkler temperature rating is identified
by the color of the glass bulb capsule as well as frame color
where applicable.

other recessed escutcheon will void all approvals and negate
all warranties. When installing Model F1S5-56 and F1S5 LO
Recessed Pendent use the Model GFR2 Sprinkler Wrench.
Any other type of wrench may damage these sprinklers.
Note: A leak tight sprinkler joint can be obtained with a torque
of 8-18 ft-lb (10.8 - 24.4 N-m). Do not tighten sprinklers over
maximum recommended torque. It may cause leakage or
impairment of the sprinklers.
Glass bulb sprinklers have orange covers to protect
the bulb during the installation process. REMOVE THIS
PROTECTION ONLY AFTER THE SYSTEM HAS BEEN
HYDROSTATICALLY TESTED AND, WHEN APPLICABLE,
THE ESCUTCHEONS HAVE BEEN INSTALLED. RASCO
wrenches are designed to install sprinklers when covers are
in place.

Maintenance
The Models F1S5-56, F1S5 LO, F1S5-56 Recessed and
F1S5 LO Recessed Sprinklers should be inspected quarterly
and the sprinkler system maintained in accordance with
NFPA 25. Do not clean sprinklers with soap and water,
ammonia or any other cleaning fluid. Remove any sprinkler
which has been painted (other than factory applied) or
damaged in any way. A stock of spare sprinklers should
be maintained to allow quick replacement of damaged or
operated sprinklers. Prior to installation, sprinklers should be
maintained in the original cartons and packaging until used
to minimize the potential for damage to sprinklers that would
cause improper operation or non-operation.
