One Inch Adjustable
Concealed Pendent Model GL5653

Description and Operation

The Globe GL5653 Adjustable Concealed Pendent Sprinkler has a low profile, aesthetically pleasing design. It offers the additional feature of greatly increased safety to life and should be used advisedly and under the direction of approving authorities having jurisdiction. The sprinkler is available with a nominal 1" of adjustment and a low profile cover plate assembly. All that is seen at the ceiling is a 3 3/8" diameter ceiling plate color finished to match the specifier's exact requirements. The GL Series Concealed Sprinkler may be virtually invisible as it does not interrupt the "smooth flow" of the ceiling.

The provided protective cap needs to be removed in order to install the sprinkler with the proper wrench. The protective cap must be replaced on the sprinkler until the time the cover plate is to be installed. The "push on - screw off" designed cover plate is easily installed with a nominal 1" inch of adjustment.

Operation of the sprinkler occurs when heat build up causes the solder holding the cover plate to the support shell to melt allowing the cover plate to fall clear. Continued heat build up causes the glass bulb to burst allowing the deflector to drop down and distribute water in an approved pattern.

Features

• Cover Plate with a gasket seal assembly for dust free environment, such as "Clean Rooms".
• Nominal 1" of Adjustment.

• Note: Globe's wrench P/N 332765 must be used to install this sprinkler.
