Product Description
Reliable Model F1 FR56 series sprinklers are quick -response
standard spray automatic fire sprinklers utilizing a sensitive 3.0
mm glass bulb thermal element.
Pendent and horizontal sidewall sprinklers may be installed
exposed or surface mounted using escutcheons such as the
Reliable Models B, C, or HB (reference Technical Bulletin 204).
When installed recessed or concealed, the Model F1 FR56 series
sprinklers are specifically listed with and may only be installed
with listed Reliable escutcheons and cover plates. Refer to the
technical information on the following pages for specific listings
for recessed and concealed installations and refer to Figures 5
and 6 for dimensional information.
When fitted with an approved water shield, these sprinklers may
considered intermediate sprinklers for use in racks, below grated
walkways, and other areas where intermediate level sprinklers are
required.
Table A provides a summary of the approvals and availability of
specific Model F1 FIR series sprinkler configurations. Additional
technical information for each sprinkler model is provided on the
following pages.

Notes:
1. Paint or any other coating applied over the factory finish will void all approvals and warranties.
2. Model FP escutcheons and Model CCP sprinklers utilize a galvanized steel cup with a finished trim ring or cover plate.
3. cULus Listed as corrosion resistant.
4. FM Approved as corrosion resistant.
5. For 200T (93°C) maximum temperature rated sprinklers only.
Installation
Model F1 FIR Series sprinklers must be installed in accordance with
NFPA13 and the requirements of all applicable authorities having
jurisdiction. Model F1 FIR Series sprinklers must be installed with
the Reliable sprinkler installation wrench identified in this Bulletin.
Any other wrench may damage the sprinkler. The Models W2 and
W4 wrenches have two sets of jaws. Use the smallest set of jaws
that fit on the wrench flats of the sprinkler. A leak tight sprinkler
joint can be obtained with a torque of 8 to 18 lb-ft (11 to 24
N•m). Do not tighten sprinklers over the maximum recommended
installation torque. Exceeding the maximum recommended
installation torque may cause leakage or impairment of the
sprinkler.
Glass bulb sprinklers have orange bulb protectors or protective
caps to minimize bulb damage during shipping, handling and
installation. Reliable sprinkler installation wrenches are designed
to install sprinklers with bulb protectors in place. Remove the bulb
protector at the time when the sprinkler system is placed in service
for fire protection. Removal of the bulb protector before this time
may leave the bulb vulnerable to damage. Remove bulb protectors
by undoing the clasp by hand. Do not use tools to remove bulb
protectors.
Maintenance
Reliable Model F1 FIR series sprinklers should be inspected and
the sprinkler system maintained in accordance with NFPA 25, as
well as the requirements of any Authorities Having Jurisdiction.
Prior to installation, sprinklers should remain in the original
cartons and packaging until used. This will minimize the potential
for damage to sprinklers that could cause improper operation or
non -operation.
Do not clean sprinklers with soap and water, ammonia liquid or
any other cleaning fluids. Remove dust by gentle vacuuming
without touching the sprinkler.
Replace any sprinkler which has been painted (other than factory
applied). A stock of spare sprinklers should be maintained to
allow quick replacement of damaged or operated sprinklers.
Failure to properly maintain sprinklers may result in inadvertent
operation or non -operation during a fire event.
