DDA Accessible Swing Door conversion using Record DFA127 operators for the University of Oxford’s Gibson Building
This project was following a DDA access audit for University of Oxford to allow easier access for all using the Gibson Building.
A survey was carried out on each door to ascertain the precise requirements and operational needs for the users. At BH Doors want to ensure that the installation, fits the requirements, provides a solution, works operationally and above all safely. Our solution was to install Record DFA127 swing operators to the existing timber door sets.
As these are security doors with integral locking, we had to interface with the access control system so that when the users tapped their card the door would automatically unlock, open and after a time delay, close and relock.
Automatic doors have a number of risks and in particular with a swing door, Impact and Crushing where the door could open or close upon a person. To eliminate this risk, we installed an on-door safety sensors from BEA called 4safes to both sides of the door leaf. During commissioning and a service, we test that these sensors are detecting correctly using a BS EN16005 test box which replicates a child stood within the sweep area of the door. The basic test is that the door should stop before touching the box during the operation of the door.
To exit the building, we installed battery powered touchless buttons which perform the same function as the access control in operation. The reason for wireless technology is that these can be installed anywhere within the proximity of the door without the need to provide containment for cabling, thus saving time and money.
On completion we tested the complete system and handed over O&M manuals, commissioning documentation and demonstrated the use to the Estates department.
