SERIES 7240 CONNECTED
FREE SWING RELEASING DEVICE
1. As the door is opened, the rigid slide
arm rotates the arm driver and the pinion shaft of the closer mechanism.
2. 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.
3. 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 Norton 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 Norton Connected Free Swing Arm Assembly is available
for application with all Series 7200 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 starting 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 80° of door
opening. The cam can be easily field adjusted to operate at virtually any degree of door
opening.
