This is our guide to help you understand more about gate safety. It is your responsibility to ensure a qualified automation installer carries out a risk assessment of your property first to ensure all safety precautions are met (signs, visual/audio aids to detect gate movement, photocells, safety edges etc where required). It is also important that after fitting they pressure test the gates, and give appropriate training on how to operate your gates safely.
There is many considerations to make when automating your gates whether it be a swing gate operation or a sliding gate.
Safety edges are used where there is any danger of entrapment or crushing may occur. They work by detecting any obstacle it comes into contact with. This then sends a signal to the main board which will stop the gates from operating (some motors will reverse and try the movement again a couple of times and if still detecting any obstruction will then cease.) Any gap that has less than 500mm width between gate and obstruction will need safety edges. If the ground is not level it is worth fitting safety edges along the bottom of the gate as this is also an area of entrapment.
On a typical installation you should expect to fit 4 x photocells. These are infra red devices that are fitted in pairs opposite each other and send an invisible signa
l/ beam that if broken will stop the gates from operating. It will detect children, adults, animals, cars etc.
Where photo cells are fitted will vary from site to site but below shows a typical set up.
Either end of sliding/ cantilever gates will need safety edges as well as any areas between the gate operating and the support posts where hands/fingers could be trapped.
Shear points are worth noting (where the gate may have gaps between bars and an obstruction could go undetected if additional safety edges and photocells are not used)
Flashing lights and audible sirens can be used to give additional warnings of the gate operating or about to operate
To summarize, gates can be very dangerous if not fitted correctly with all risk assessments taken place prior to any installation and every installation is different. We would always recommend against DIY fitting and opt for a qualified automation installer.
