Leeds University Bus Gate Bollard System

Sir William Henry Bragg won the 1915 Nobel Prize in Physics with his son Sir William Lawrence Bragg for the development of X-ray crystallography.

Their work revolutionised science by allowing researchers to examine the atomic structure of materials in detail for the first time.

Now the Sir William Henry Bragg Building will form a vital part of the new developments on campus. Together with the Bragg Research Centre, which recognises both father and son, it will bring researchers together to create a critical mass in ground-breaking interdisciplinary research and impact.

The designers wanted a secure area and route – from the front of the building to the rear – for deliveries whilst also protecting the area from unwanted vehicles and controlling the bollards from the reception desk. They also requested the bollards to be linked to the building fire alarm, which would automatically lower the bollards if activated.

Macs specified the 275/P800 Automatic Hydraulic Bollard.

This integrated bollard hydraulic pump is fitted with a solenoid valve wired to the fire alarm. This enables an automatic lowering in the event of a fire alarm being raised. The pump also has an integrated safety pressure switch and if any pressure is detected during the raising process, the bollard automatically lowers, reducing any damage to vehicles.

The bollards are controlled via an intercom, supplied and fitted by TIS, who look after access control and fire detection equipment on campus. Users approach the automatic bollard installation and stop in the designated area; they press the call button on the intercom, which connects to a telephone in the reception area. If access is permitted, the receptionist presses a key on the telephone keypad, which commands the bollard down. Once the vehicle has cleared the automatic bollard – and a series of induction loops – the bollard raises behind the vehicle.

Exit through the installation is fuss-free with a ‘free exit’ induction loop system. Users approach the structure; when their vehicle is within five metres of the bollards, they automatically lower. Once the vehicle has cleared the bollard – and a series of induction loops – the bollard raises behind the vehicle.

The main contractor awarded the build contract was BAM.
