ESCRIPTION AND
The Globe Quick Response GL Series Dry Type Upright Sprinkler is
designed for use in special applications such as freezing environments.
As an example, they may be effi ciently used when connected to a wet
type sprinkler system and extended into an unheated attic space.
The Globe Quick Response GL Series Dry Type Upright 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 approving 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 tem-
perature 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.
