Automatic Swing Door Operators Do I need safety devices with a low energy door operator?What power supply do I need to provide?What happens in the case of a mains power failure?Can the unit be fixed to the door?What is the largest size door leaf that can be operated?How do I prevent unwanted actuation of the door from passing traffic?Can the door be actuated by access control?Can I fit an operator to an existing toughened glass door assembly?Who do I contact to help me choose the correct unit for my particular application?Can the doors be powered open upon the actuation of the fire alarm?Can I use the ED200i to automate all glass doors?Do I need IRS safety sensors?What fixing support do I need to provide?Can a swing door operator be used to control fire doors?Can a door fitted with an automatic operator swing in both directions?
Low energy swing door operators, such as the DORMA ED800, are generally not fitted with safety devices, as kinetic energy levels are not considered to be dangerous. However a hazard analysis and risk assessment should be carried out to establish that the risk to these users is low. Please contact 01462 477600 if you require assistance in carrying out your hazard analysis and risk assessment.
A 240-volt AC mains spur to the left-hand side of the opening above and on the same face that each drive unit is fitted. The spur must be switched and fused with a central flex outlet faceplate. A 10 amp residual circuit breaker at the main board and a 5-amp fuse at the spur will protect the circuit. One spur is required for each single or each pair of doors.
The doors will revert to manual operation controlled by the integral hydraulic pump.
Due to the weight of either the ED200 & ED800 and the provision of a mains power supply to the door, the unit cannot be fitted to the door. The unit must be fitted to the area immediately above the door. It is important to ensure that there is sufficient depth between the top of the door and the ceiling/soffit to accommodate the unit, (see brochure or contact 01462 477600 for specific details). It is also important to ensure that the area where the unit is to be fixed is reinforced sufficiently to accommodate the unit.
The maximum sizes for the ED200/ED200i is 1600mm, and 1200mm foe the ED800. Further technical information is provided in the relevant product brochures. However these sizes are not necessarily suited for all applications. Please contact 01462 477600 for specific advice.
Push pads can be used for actuation instead of radar movement detectors. However the following should be considered before selecting a specific product. We generally do not recommend the use of push pads to actuate fully automatic doors used by the general public as users expect a fully automatic door to open.
There are provisions within the operator to interface with most types of access control systems. It should be noted that a suitable locking device would need to be incorporated to provide security. Due to the variation in applications and systems we would strongly recommend that you contact 01462 477600 for project specific advice.
The assembly must have an existing "goal post" frame and the doors must incorporate top and bottom rails.
Contact our technical department on 01462 477600. They will provide proposals and/or specifications, or if necessary arrange for a technical representative to visit site or your office.
The doors can be powered open but to remain open the mains power must be available. Upon a power failure the door will close. To enable the doors to remain open, the provision of an auxiliary power supply is required.
If a "goal post" frame is provided and DORMA Glass door top and bottom rails are used. The ED200I enclosure forms the transom of the goal post frame. The rails are required for fitting IRS safety sensors and to protect the bottom edge of the glass.
BS 7036 Part 3 states that 'provision should be made to protect traffic occupying the swept area during both the opening and closing cycles either by: · A presence sensing device which interrupts the door movement at any point during its cycle (IRS) or: · A presence sensing device or safety mat which gives limited protection by preventing a fully open or fully closed door from moving. Due to the limitation of the second option we only install ED 200 operators with IRS sensors unless a risk assessment identifies that the doors will only be used by trained traffic.
The structure immediately above the door must be sufficient to support the weight of the operator, (18KG), and the forces imposed during operation. Typically a stud wall should be reinforced with timber grounds and a glazed transom should be fitted with a substantial metal fixing plate spanning the vertical frame members.
Yes, both ED200 and ED800 units have been tested to control fire doors. For rebated pairs a selector must be used to ensure that the doors close in the correct sequence.
For safety reasons automatic swing door operators are only designed to operate the doors in one direction. The only exception is where the doors are required to 'break out' manually in the opposite direction to the direction of normal operation for emergency escape purposes. This option is only available with ED200i units, which cannot be used to automate existing doors. See brochure for size limitations or contact 01462 477600 for further information. |
