Swing Door Operators
A ‘swing door operator’ is a device that operates a swing door, it opens or helps open the door automatically, waits, then closes it.
There are 3 basic types of swing door operators:
This opens and closes the door at full speed. Full Energy operators are typically used on the outside doors of medium sized retail businesses.
This opens and closes the door at reduced speed, in order to limit the kinetic energy of the moving door to levels deemed safe for disabled users. Low energy operators are typically used where a simple door closer is sufficient for abled users, yet it is necessary to add access to disabled users eg: small businesses, apartments, bathrooms.
This is a version of the Low Energy operator. Instead of opening the door, it lets the user open the door manually at a reduced force, compared to opening against a standard door closer. It closes the door with the same speed limitations as a Low Energy operator.
A door operator may be triggered in various ways:
• Approach Sensor (such as a radar sensor) – the door opens when a user approaches it.
• Push Button – the door opens when a user presses a button.
• Push & Go – the door opens fully when the user begins opening it.
• Access Control – the door opens when the access control system determines the user is authorised to go through.
A trigger from any of the above requests that the door be opened (or reopened if it was closing). The operator will heed that requests only after it is able to do so safely for any other users in the area.
A door operator can use sensors to prevent the door from coming into contact with a user.
Full Energy operators require safety sensors. Low Energy Operators are not required to have safety sensors, as the door is allowed to come in contact with a user, given that the kinetic energy of the moving door is limited by the reduced moving speed.
Sliding Door Operators
A sliding door operator is a device that operates a sliding door, it opens the door automatically, waits, then closes it.
Sliding door operators are typically used on the outside doors of large retail businesses.
A sliding door operator may be triggered in the same ways as a swing door operator and will reopen if the door closes into an obstacle. Most operators use sensors to prevent the door from ever coming into contact with a user in the first place. The operator is placed in the space above the sliding door.
Many premises with existing older type automatic sliding door equipment, may find it difficult to source replacement spare parts. If this is the case our “Retro-Fit Kit”, makes it possible to improve and upgrade your existing door installation, regardless of make and model.
The existing track and cover is retained, and with a typical conversion time of around 4 hours or less including wiring and set up, the “Retro-Fit Kit” can significantly reduce the time and inconvenience that would be caused if replacing old for new.
Automatic Swing Doors - Fully Automatic and Low Energy
Fully Automatic Doors:
Fully automatic doors are most commonly found in retail situations, the doors open as they are approached from either side by pedestrians. Where the doors are sent a signal to open automatically, usually by motion sensors, additional safety measures must be taken to ensure the safety of the pedestrians using the doors.
Low Energy Doors:
Low energy doors require an action by the pedestrian to activate the door, this can be a number of things but usually takes the form of a push pad which, when pressed, sends an activation signal to the operator to open the door. Low energy doors move with less force and speed than fully automatic doors and so do not require any safety sensors, however, where the users are likely to be elderly, infirm or disabled a safety sensor which prevents the door from closing on anyone lingering in the threshold area is recommended.
Low energy doors can still be used as manual doors by the able bodied as the resistance posed by the operator is no more than a standard manual door closer.
These installations are a perfect solution for compliance with the Disability Discrimination Act.
Features available for all automatic door installations include:
• Full on-door safety to prevent accidental striking of pedestrians
• Variable opening and closing speeds
• Hold open facility
• Fail open on fire signal – battery backup connected to fire board
• Guaranteed closing of the door, even during power failure – for fire doors
• Variable length of hold open time during cycle
• Break out facility
• Safety barriers where required
Our extensive range of operators ensure that our client’s needs are fully met. We can configure the operators to open on fire alarm or alternatively, always close fully to maintain the integrity of fire doors.
Automatic Sliding Doors
We use the latest technology from Italy, Germany and Switzerland to power our automatic sliding doors. All of our products are CE approved very high quality and are proven to be reliable. We have a range of automation units including one which is only 10cms (4″) high; this product fits unobtrusively into almost any opening. It is particularly appropriate where headroom is limited and for ‘all glass entrances’ where larger automation units would spoil the overall appearance.
All of our products are extremely reliable, low maintenance and are suitable for both single and double leaf doors. Heavy door leaves can be automated through the use of additional heavy duty carriages.
Standard features we offer on all sliding doors are:
• Full threshold safety
• Side screen safety
• Pocket screens – where required
• Emergency opening in the event of a fire or power failure
• Various methods of activation – for more information please click here Activation & Access Control.
If you are considering installing a single or double sliding door set into an opening the following information will be useful:
Single Sliding Door:
The minimum brick to brick width required for a single sliding door opening over a side screen allowing a clear opening of 1,000mm and without a pocket screen is 2,450mm.
Bi-Parting Sliding Doors:
The minimum brick to brick width required for a pair of sliding doors opening over two side screens allowing a clear opening of 1,000mm without pocket screens is 2,770mm
The above measurements allow the back stile of the door to stop 200mm from the brickwork to prevent trapping hazards and to comply with BS7036. Where this BS7036 requirement would reduce the clear opening unacceptably a pocket screen can be erected in front of the fixed side screen to create a pocket for the door to open into. Pedestrians are protected from trapping hazards by the screen so the door can open right back to the walls thus increasing the available clear opening by 200mm for a single door and 400mm for a pair of doors.
Where the opening is narrow, providing there are no impediments to the door opening over the face of the building, the door/s can be hung on the inside face of the opening and the door/s can then open over it.
