Product Description

The Reliable Model HL22 is an Early Suppression
Fast Response (ESFR) Sprinkler with a nominal K-factor of 22.4
(320 metric). The sprinklers use a levered fusible alloy solder
link in either a 165°F (74°C) or a 212°F (100°C) temperature
rating. These sprinklers are designed to respond quickly
to growing fires and will deliver a heavy water discharge to
"suppress" rather than "control" fires.
FM Approvals classifies the Model HL22 as a quick-response
sprinkler, storage and non-storage, when used in accordance
with FM Global Property Loss Prevention Data Sheets.
In addition to the design criteria provided in NFPA 13, the Model
HL22 also has a Specific Application UL listing for 45' storage
of Class I - IV and cartoned unexpanded Group A plastic in a
48' building (reference Table C for full details).
The HL22 sprinklers are available with
, and also with the Victaulic® IGS™ Style V9 Sprinkler
threads
