Reliable HL22 Manual

Product Description

The Reliable Model HL22 is an Early Suppression Fast
Response (ESFR) Sprinkler with a nominal k-factor of
22.4 (320 metric). This sprinkler is designed to respond
quickly to growing fires with a high volume of water
discharge to "suppress" rather than "control" fires.
FM Global classifies the Model HL22 as a quick-
response sprinkler, storage and non-storage, when the
sprinkler is used in accordance with FM Global Property
Loss Prevention Data Sheets.
The Model HL22 sprinkler utilizes a levered fusible
alloy solder link in either 165°F (74°C) or 212°F (100°C)
temperature rating. The sprinkler has a nominal K Factor
of 22.4 (metric 320), and is available with 1" NPT or
ISO 7-R1 threads, or with the Victaulic® IGS™ Style V9
Sprinkler Coupling*.
