Briton 996 Door Closer | Electromag Hold Open or Swing Free

Briton 996 Door Closer | Hold Open or Swing Free

The Briton 996 series is a range of door closers with an integrated electromagnetic hold open or swing free function. Each unit can be set to either ‘hold-open’ or ‘swing free’ operation. The door will hold open in either instance and allow free passage so these units are ideal for high traffic areas such as corridors.

When a fire alarm is activated or there is power failure, the electromagnet disengages and the door closer closes the door in the normal manner to maintain fire safety; preventing the spread of smoke and fire.

Functionality:

Once you have chosen the correct power size and fixing configuration for your application, the 996 closer has selectable hold open of swing free function within the same unit. Simply set the catch plate to the desired function when installing the closer.

• Hold Open – The door leaf will be held rigidly open until pulled close or electromagnetically released.
• Swing Free – The door lead acts as though there is no closer on the door for assisted opening, however, it will close in the event of a fire (if linked to fire alarm system).  Please note that when used in this mode, the Briton 996 damping action is ineffective and the door will slam in draughty conditions.

The angle of hold open can be adjusted from c.85° to 95°, and c.103° to 110°, and the variance of swing free is also c.85° to 95°. The maximum opening angle of the door is dependent on the surrounding structure, plus any hinge finger protection that may be fitted.

Briton 996 Door Closer Power Supply

You will need a power supply unit (PSU) to provide power to this electromagnetic door closer. The size / capacity of the PSU will depend on the number of units and other items of access control installed. You can read more about this subject in our blog 'A Guide to Power Supply Units in Access Control Systems'.

As the 996 closer also has optional rear cable entry, you may require a separate concealed door loop when installing.

Briton 996 Door Closer Manual

In the Product Manuals section below, you can view or download various technical documents for this overhead closer. This includes the DOPs (Declaration of Performance), datasheet, and the Briton 996 installation instructions for all mounting options, which include detail on door closer adjustment.

These units are ideal for high traffic areas due to their strong, durable design, plus the convenience of having fire rated doors held open safely, or utilising the swing free feature. Bedroom doors in care homes frequently utilise the swing free function, so doors open and close more naturally, as they would in a domestic setting. Whereas the hold open function is the perfect choice for frequently used doors where there is a large volume of pedestrian traffic such as a school or college, or where large items are moved around, such as corridor doors or ward entrance doors in hospitals.
