Product Description
Reliable Model F1 series sprinklers are standard-response
standard spray automatic re sprinklers utilizing a 5.0 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, the Model F1-56 series sprinklers
are specically listed with and may only be installed with listed
Reliable escutcheons. Refer to the technical information on the
following pages for specic listings for recessed installations and
refer to Figures 7 and 8 for dimensional information.
When tted 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 specic Model F1 series sprinkler congurations. Additional
technical information for each sprinkler model is provided on the
following pages.

Installation
Model F1 Series sprinklers must be installed in accordance with
NFPA13 and the requirements of all applicable authorities having
jurisdiction. Model F1 Series sprinklers must be installed with the
Reliable sprinkler installation wrench identied in the Design and
Installation Information table in this Bulletin. Any other wrench may
damage 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 re 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.

3. cULus Listed as corrosion resistant.
4. FM Approved as corrosion resistant.
5. For 200°F (93°C) maximum temperature rated sprinklers only.
6. LPCB and VDS approved for SIN RA1314 and RA1325.
7. Clear wax used on ordinary temperature rated sprinklers; brown wax used on intermediate temperature rated sprinklers. Brown wax may be used on
high temperature rated sprinklers where the ambient temperature does not exceed 150°F (66°C).
8. Not available for 500°F (260°C) temperature rated sprinklers.
Sprinkler and Escutcheon Finishes(1) Table B
Maintenance
Reliable Model F1 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 re event.
