The Globe Quick Response GLSeries Dry Type Upright Sprinkler is
designedforuseinspecialapplicationssuchasfreezingenvironments.
As an example, they may be efficiently 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 flows through the sprinkler and is distributed by the
deflector,inanapproveddischargepattern.Itcanbeinstalledwherever
standard spray sprinklers are specified 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 GLSeries sprinkler proven actuating assembly
isahermeticallysealedfrangibleglassampulethatcontainsaprecisely

bulb expands increasing the internal pressure. At the prescribed tem-
perature the internal pressure within the ampule exceeds the strength
oftheglasscausingtheglasstoshatter. Thisresultsinwaterdischarge
which is distributed in an approved pattern.
