SRI| For installations where a higher level of protection against weather
conditions, or the effects of a potentially corrosive atmosphere is required,
LCN offers a special rust inhibiting (SRI) process. Ferrous metal components
receive an SRI pretreatment and a standard powder coat finish of your choice,
or a custom powder coat finish for a nominal additional cost. Closers treated
with the SRI process exceed the 100 hour protection level available with
standard LCN powder coated finishes.
Testing and Compliance
Fire Rating:
Successfully tested on fire door assemblies in accordance with AS1905 Part1:
Fire resistance doorsets. Check with fire door manufacturer prior to
installation.
Accessibility:
Compliant to the AS 1428:1-2009 Design for Access and Mobility
Caution:
When door closers are installed and adjusted to meet reduced opening force
requirements, there may be 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, the LCN
Automatic Door Operators are recommended.
Selection chart
Select strength based on width of door
| Strength | Exterior door | Interior door |
|---|---|---|
| 1 – 2 | NA | 660mm – 864mm |
| 3 | 660mm – 762mm | 864mm – 965mm |
| 4 | 762mm – 914mm | 965mm – 1219mm |
Regulating controls
The LCN 4031 has independent regulators to control:
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 latch bolts or air pressure conditions.
Alternatively the latching speed can be decreased to cushion the door into the
frame. The latching speed adjustment operates from 15° to closing. A further
option to increase the latching power is to reverse the arm bracket shoe
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
Power adjustment| Spring strength may be increased or decreased by turning the
allen head screw located in the end of the door closer body
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 stay open at a single point. Hold open closers can not be used on fire doors
