Product Description
The Reliable Models F156 and F1FR56 Intermediate Level
Sprinklers include shields which protect the glass bulb from
water spray impingement caused by sprinklers located at a
higher elevation.
Typical applications are for storage racks which require
multi–level sprinklers and beneath open grid catwalks.
Application
Model F156 and F1FR56 Intermediate Level sprinklers are
used in fixed fire protection systems: Wet, Dry, Deluge or Pre-
action. Care must be exercised that the orifice size, tempera-
ture rating, deflector style and sprinkler type are in accordance
with the latest published standards of the National Fire Protec-
tion Association or the Authority Having Jurisdiction.
Installation
Model F156 sprinklers are standard response sprinklers
and Model F1FR56 are quick response sprinklers. Both types
are intended for installation as specified in NFPA 13. Upright
sprinklers must be installed with the Model D Sprinkler Wrench
specifically designed by Reliable for use with these sprinklers,
and pendent sprinklers must be installed with the Model GFR2
Sprinkler Wrench specifically designed by Reliable for use

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. Model D and GFR2 wrenches are designed to install
sprinklers when covers are in place.
Maintenance
The Models F156 and F1FR56 Sprinklers should be inspect-
ed and the sprinkler system maintained in accordance with
NFPA 25. Do not clean sprinklers with soap and water, am-
monia or any other cleaning fluid. Remove dust by using a soft
brush or gentle vacuuming. 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 or non-
operation.
