The LCN 1461 is designed for reduced opening force which when set to a 1 strength makes it suitable for use by people who are
frail, aged or disabled. This closer can operate at between 14-20Nm from initial opening up to 90°
Caution! Where door closers are installed and adjusted to meet reduced opening force requirements, there maybe insufficient power to
reliably close and latch the door, depending on prevailing operating conditions
Note In areas of high wind pressure and/or air conditioning pressures or doors located in exceptionally heavy traffic or oversized/
heavy doors, the LCN 4041 series closers or LCN automatic door operators are recommended

Functions
Regular For applications where the door must fully close after each opening
Hold open Suitable for doors where the door may need to be left in a hold open position. The hold open function can be set
to hold open at a single point. Hold open closers can not be used on fire doors
Delayed action Delayed action closers have an inbuilt adjustable control that delays the closing of the door, for up to
approximately 1 minute
Cush-N-Stop®Used predominantly on outward swinging doors in situations where it is not practical to fit a door stop. The
Cush-N-Stop®function has a built in stop incorporated into the arm to prevent damage to the closer, door or
frame in the event of an abrupt stop. It is recommended that metal door frames be reinforced where the arm
attaches to the transom. Maximum door opening 100°
Hold open Cush-N-Stop®Provides the same function as the Cush-N-Stop®, but has the added feature of a hold open function in the arm,
which is engaged/disengaged by a tee handle. Maximum door opening 100°
Regulating controls
Closing speed Adjustment to increase or decrease the speed at which the door closes. This allows the appropriate momentum
to close the door in a safe and secure manner. Closing speed adjustment operates from the maximum opening
to 15°
Latching speed The latching speed allows the door to close quietly and firmly. It can be adjusted to increase or decrease the
speed at which the door finally closes. This assists the final stage of the closing cycle to help overcome stubborn
latchbolts or air pressure conditions. The latching speed adjustment operates from 15° to closing
Backcheck Adjustable hydraulic backcheck provides a cushioning effect when the door is forcibly thrown open to prevent
damage to the closer, door and frame. The backcheck adjustment allows the level of resistance in the latter
stage of opening to be set at the level required. Backcheck is effective from 75°. Backcheck is a requirement for
all fire rated closers
Delayed action Enables door closing action to be delayed for an adjustable period of time before resuming normal closing,
allowing slow moving traffic to pass through. Delay action can be adjusted up to a delay time of approximately 1
minute. Operational zone of delay is between 180° to 75°
Power adjustment Spring strength may be increased or decreased by turning the allen head screw located in the end of the door
closer body
The LCN 1461 has independent regulators to control

Regular mounting has a maximum opening of 180° , with frame and trim
permitting. The hold open arm allows the door to be set at one given hold open
point up to the maximum opening. The reveal should not exceed 19mm for a
regular arm or 13mm for a hold open arm. Top rail less than 64mm requires
adaptor plate. Adaptor plate requires a 38mm minimum top rail. Clearance of
70mm behind door is required for 90°installation. Delayed action closer delays
closing from 110°to 65°or 160°to 75°depending on templating

Regular (pull side) mounting
Top jamb mounting has a maximum opening of 180° . The hold open arm allows
the door to be set at a given hold open point up to the maximum opening. A
reveal of 64mm for hold open arms and 89mm for regular arms allows a 180°
opening. Top rail less than 48mm requires adaptor plate. Adaptor plate requires
a 70mm minimum top rail. For situations where the head frame is less than
44mm or a flush ceiling condition exists with a 51mm head frame, an adaptor
plate is required. Adaptor plate requires a 32mm minimum head frame. Delayed
action closer delays closing from 110°to 75°or 180°to 95°depending on
templating.

Cush arms can be templated for the following maximum opening/hold open
points:
1. 85°- A = 60mm & B = 243mm
2. 90°- A = 41mm & B = 230mm
3. 100°- A = 16mm & B = 205mm
Clearance for the cush shoe is 140mm from door face. Top rail less than
108mm measured from the stop requires drop plate. The drop plate requires
a 44mm minimum top rail
Cush-N-Stop®(push side) mounting
Parallel arm mounting has a maximum opening of 180°. The hold open arm
allows the door to be set at one given hold open point up to the maximum
opening. Clearance for the PA shoe is 102mm from door face. Top rail less
than 108mm measured from the stop requires drop plate. The drop plate
requires a 44mm minimum top rail. Minimum stop width is 25mm. Blade stop
clearance requires 13mm blade stop spacer. Delayed action closer delays
closing from maximum opening to approximately 75°. When installing closers
in parallel arm configuration, strength may be needed to be adjusted upwards
to compensate for power reduction
