Door Closer CE EN 1154

1.Power Size

1.1 The power of a door closer should relate to the width and weight of the Door onto which it is to be fitted. The chart opposite provides a guide to selecting the appropriate product.

1.2 Closer are designed to specific strengths i.e. 'fixed' strength or variable strengths whereby the power is either 'adjustable' within the mechanism itself or 'selectable' via a template.

1.3 When fitting a closer on a parallel arm installation (app.66), it is usual to experience some power loss and a stronger unit may be needed. However, some D&D closer retain their strength regardless of application.

1.4 Certain environmental factors could impact on the open force of the door, e.g.wind pressures. If unusually windy or draught conditions are expected, select the power size for the next door width.

3.Applications
 
 
 

  

Backcheck

Backcheck offers resistance to opening between 70 degree and 90 degree when the door is opened with excessive force. Useful in all situations. Helps prevent damage to building and door frames, particularly where opening is restricted. NOTE :Backcheck is not a substitute for door stops which should be fitted wherever possible.
 

 

Delayed Action

Delayed action slows down the closing speed of the door between approx 90 degree and 65 degree. The amount of delay can be adjusted and de-activated altogether. Ideally suited for applications, such as care homes, where people need a grater length of time to exit doorways.

Controlled Closing

All D&D door closers have an adjustment value which allows the losing speed to be controlled. this is effective throughout the whole closing cycles except where delayed action or latch action are activated.
 

Controlled Closing

Latch action provides for the adjustment of the last 10 degree (approx) of the closing cycle.This allows the closer to be adjusted to overcome a latch or instumescent seal.
 

4.Slide Arm Application

Can be used where it is undesirable to have a projecting arm.consists of a single arm connected to channel mounted above the door. (Not suitable for doors with projecting architraves).
