Gate Automation at Stanmore College

This school required a more secure gate at the entrance of their staff carpark so we converted their existing standard gate into a motorised gate using underground gate automation. Here’s how we did it;

Gate automation solution –  From an existing crooked, manual gate to a fully motorised gate

We were approached by Stanmore College who required help to convert their existing standalone gate. They wanted to create a more secure solution using gate automation, whilst keeping the existing gate and posts with the original frame.

Gate automation - original crooked manual gate

So we started by removing the gate, which was twisted and lob-sided. We straightened it up and corrected the angle of it. We did this by removing the old hinges and welding new ones in their place.

The next step was to carry out some groundworks to install new underground motors, as well as an induction loop. On this occasion, this would NOT facilitate automated exit. Instead, it would trigger the gate to stop as the vehicle is passing through.

It was also important to the customer for the staff to be able to use access cards to open the gate on entry and also on exit. So we installed card readers on entry and on exit. This was successfully done and the gate is now automated as well as triggered by the proxy cards via the card readers.

Scope of works

The automation of the existing small car park gate, which will incorporate reader capability for entry and exit, a maglock and underground motors.

The power for the gate automation is taken from the fuse board in the corner classroom. The two network cables for the readers have been run back to the network cabinet on the 1st floor of the same building as the fuse board.

The free issue readers have been installed on the right-side fence post on the exit and the right-side gate post on entry. Users will need to exit vehicles to use the readers.

Safety features of the gate automation

This is a very important element of any new automated gate because there is a risk of human injury in a motorised gate. However, this is overcome in the following ways;

🔹 Photocell technology installed, which senses when an individual gets close.

🔹 There are safety strips installed on the inside of the gate and at the bottom on both the left and the right side of the gate. This is because there is a crushing point in between the fence and the gate.

🔹 There is also a safety strip on the inside of the head of the leading gate to prevent persons being crushed. It is always important that each leaf of the gate closes at separate times to the other. Therefore, reducing the risk of human injury

🔹 Several ‘No Pedestrian Access’ signs have been installed to deter individuals from trying to enter through the gate and running the risk of being crushed.
