ESCRIPTION AND
The Globe Quick Response GL Series Dry Type Horizontal Sidewall
Sprinkler is designed for use in special applications such as freezing
environments and conditions where sediment or foreign materials might
accumulate in ordinary horizontal pipe nipples.
The Globe Quick Response GL Series Dry Type Horizontal Sidewall
Sprinkler utilizes a 3mm frangible glass ampule as the thermosensitive
element. This provides sprinkler operation approximately six times
faster than ordinary sprinklers. At the ampule's rated temperature,
the sprinkler opens releasing the bulb seat, causing the inner tube
assembly to move, allowing the spring assembly to pivot alongside
the inner tube. At this time, water fl ows through the sprinkler and is
distributed by the defl ector, in an approved discharge pattern. It can be
installed wherever standard spray sprinklers are specifi ed but offers the
additional feature of greatly increased safety to life. Quick Response
Sprinklers should be used advisedly and under the direction of approv-
ing authorities having jurisdiction.
The heart of Globe's GL Series sprinkler proven actuating assembly
is a hermetically sealed frangible glass ampule that contains a precisely
measured amount of fl uid. When heat is absorbed, the liquid within
the bulb expands increasing the internal pressure. At the prescribed
temperature the internal pressure within the ampule exceeds the
strength of the glass causing the glass to shatter. This results in water
discharge which is distributed in an approved pattern.
