1600 SPECIAL FEATURE CLOSERS
 Adjustable
Delayed Action Closing: Order Series 1600-DA.
An optional hydraulic feature, that adds a third speed
range to the closing cycle. This feature becomes effective when the door is opened and
released at any point beyond 70°. This feature is not available in the Series 1600BC
closer. The amount of time delay depends upon the combination of the angle of the door
release and valve adjustment. The valve can be adjusted with a 1/8" hex key from no
delay time up to maximum delay times of:
| Door Opened and Released at |
Approximate Time of Delay Cycle |
| 180° |
4-5 minutes |
| 120° |
2-3 minutes |
| 90° |
25-30 seconds |
Pressure 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.
Suggested Applications: 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
wheel chairs to pass through a door without concern of it closing. At the same time, it
can accommodate the facility's staff with movement of food service carts, beds 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 are advantageous are doors to computer rooms, doors between office
and factory/ warehouse facilities, doors to workshops and to laboratories, to kitchen and
food processing areas . . . to list just a few.
Telephone Booth Operation:
Order Series 1600-TEL. Closer holds the
door to the telephone booth open at 5° from the closed position. This prevents the light
switch from being activated and allows the booth to be ventilated. It also indicates to
users that the booth is unoccupied. The person using the booth then closes the door from
the 5° open position.
The closer does not start spring compression until the door
is opened Beyond 5°. To further assure the door remains open, the latch speed regulating
valve is almost completely closed. This prevents the inertia of a closing door from
passing through the 5° opening point.
Available in size 2 only for regular arm, top jamb or
parallel arm application.
Coupon Booth Hold-Open:
Order Series 1600-COUP and specify hand of door.
Most commonly used on doors to safe deposit box inspection cubicles. Closer holds the door
to the coupon booth open at 15° to indicate that the booth is available for use by a
safe-deposit-box renter. When the door is opened, the closer will close the door and
engage the lock, providing the occupant with the desired privacy. When the occupant is
finished with the booth, the closer will again close the door and engage the lock. lhe
attendant with a key can then open the door, examine the booth for articles left in error
and reset the door at 15° opening.
Hold-Open is accomplished by a spring-loaded roller and a
detent in a cam. The roller assembly is attached to the closer housing; the cam is
attached to the pinion shaft.
When the door is opened to 15°, the roller engages the
detent and holds the door. Spring tension of the roller is adjusted by a 5/32"
hex-key. Spring tension can be set to just hold the door when opened to 15°. Yet, when
the door is opened fully and released, the inertia of closing will prevent the roller from
stopping at the 15° hold-open point. Available in sizes 2 and 3 only for regular arm, top
jamb or parallel arm application.
Hospital Hold-Open:
Order Series 1600-HOSP and specify hand of door.
Closer wilt hold the door open at approximately 15° for ventilation, 45° for observation
and beyond 90° for full access.
Closer is supplied with a standard hold-open arm for the
beyond 90° hold-open position. The 15° and 45° hold-open positions are accomplished by
a spring loaded roller and two detents in a cam. The roller assembly is attached to the
closer housing: the cam is attached to the pinion shaft.
When the door is opened to 15°, the roller engages the
first detent and holds the door. When the door is opened to 45°, the roller engages the
second detent and holds the door. The standard hold-open arm can be adjusted to hold the
door at any degree beyond 90°. Spring tension of the roller is adjusted by a 5/32"
hex-key. Spring tension can be set high enough so it will engage the detents in the cam
when the door is opened beyond 70° and released. Or it can be set low enough that the
inertia of the closing door will not engage the detents and allow the door to close
completely when it is released.
Available in sizes 3 and 4 only for regular arm. top jamb
or parallel arm application.
