DELAYED ACTION

ㆍAdjustable Delayed Action Closing

An optional hydraulic feature that add a third speed range to closing cycle. This feature becomes effective when the door is opened and released at any point beyond 70˚. The amount of time delay depends upon the combination of the angle of door released and valve adjustment. The valve can be adjusted with 4mm hex key from no delay time up to maximum delay times of :

Door opened	Approximate Time of Delay Cycle
180˚	4~5 minutes
120˚	2~3 minutes
90˚	25~30 seconds

ㆍPressure Relief Safety Valve

The delayed action hydraulic system contains a pressure relief valve. Any time the door is forced toward the closed direction while it is in the closing cycle, the valve will open and permit the door to close. This prevents damage to door, frame and closer.

ㆍSuggested Application

Delayed action closing allows slow-moving traffic to clear the opening before the door closer’s normal closing cycle begins. This feature can be helpful in health care facilities such as hospitals and nursing homes. It provides sufficient time for persons on crutches or in wheelchairs to pass through a door without concern of closing. At the same time, it can accommodate the facility’s staff with movement of food service carts, bed, and other wheeled traffic.
Use of delayed action closers on many doors throughout industrial and commercial buildings can also assist the flow of traffic. Locations where additional time to clear the opening is advantageous are doors between office, doors to workshops or laboratories, kitchens and food processing area.
