 4240 SERIES CONNECTED FREE SWING
RELEASING DEVICE
- As the door is opened, the rigid slide arm rotates the arm
driver and the pinion shaft of the closer mechanism.
- When the door has been opened and released, the unit's
electrically controlled plunger valve will hold the pinion shaft and arm driver at that
degree of door opening. The door is then free to swing unhindered.
- After Fire/Smoke detection alarm or any power interruption
to the control, the pinion shaft and arm driver are released to close the door.
The Yale Connected Free Swing Arm Assembly provides
convenient automatic closing fire door protection for the patients and staff of health
care facilities.
An arm driver connected to the closer pinion drives the
pinion when the door is opened and the slide arm rotates. When the unit is energized the
pinion and arm driver are held in the position to which the door was initially opened, by
means of a solenoid operated plunger valve.
The arm is connected to the pinion but is free to pivot.
The door, in turn is free to open, close or be set at any degree of opening unhindered by
the closer spring.
When there is a Fire/Smoke alarm or any power interruption,
the hold-open control valve is released, permitting the Connected Free Swing Arm Assembly
to close the door.
Since there is no closer spring force on the door during
the normal operation, patients the handicapped and/or staff find the door easy to open,
close or leave ajar. This is an ideal product for application in health care facilities,
or other locations where it is desired to neutralize the effort required to open or close
a door.
The Yale Connected Free Swing Arm Assembly is available for
application on either 4200 Series Master or Support Units. This top jamb, pull (hinge)
side control with slide arm and track is for installation on patient room or similar
doors.
The Connected Free Swing Arm is also available for
application on the Executive Door Holder/Release.
Optional Selective Hold-Open Switch and Cam: The
Selective Hold-Open staring point is determined by a switch and adjustable cam assembly.
The cam is attached to the upper pinion shaft by means of a machine screw. As the door is
opened, the pinion shaft will rotate the cam and operate the switch to the "On"
position to initiate hold-open. When the door is closed, the pinion cam will operate the
switch to the "Off" position.
The cam is factory set to operate at 80º of door opening.
The cam can be easily field adjusted to operate at vitually any degree of door opening.
