Junior School, Portsmouth
On this project, we were contacted by the Site Manager of the School to provide a solution which would allow wheelchair access into the school. The current door was manually operated and was fitted with an overhead magnetic lock connected to a Paxton fob access system to allow staff to unlock the door. The door remained locked for all other users. The reception staff have a button to release the door under the desk. The door was also fitted with a green emergency exit button and connected to the fire alarm to ensure that the door unlocked in the event of a fire.
The customer was keen to keep using the same door due to budgetary constraints, as a new door would be costly. The current door was manually operated and was fitted with an overhead magnetic lock. The height under the frame head was already quite low (1965mm) to the underside of the magnetic lock. Unfortunately this would be a problem as the automatic door drive unit is too long to fit into the space remaining.
A proposal was put together to automate the current door. This entailed the fitting of two, polyester powder coated, bespoke manufactured aluminium mounting plates. This would allow the equipment to be mounted in the correct place and still provide as much head-room under as possible. A slimline (Dorma ED100/A) automatic door operator was chosen due to the very low, 70mm profile.
The old electro-magnetic lock was replaced with a Micro-power lock, which has a very small footprint, but still has an impressive 680kg holding force. This allowed enough room for the Dorma ED100/A to fit next to it.
A standard, laminated glass infilled, floor to wall safety barrier was fitted externally for compliance with BS EN16005
"BEA 4Safe" on-door Active infra-red safety sensors were fitted internally and externally to ensure that the moving door is safe for everyone and compliant with BS EN16005.
