Photocells
These are the most common type of device used to provide 'hold open' safety. Photocells work by emitting an infrared beam across the driveway. The infrared beam is constantly monitored by the photocell receiver unit; if the beam is interrupted (broken) the receiver unit sends a signal to the electronic control unit. Normally, photocells are used to prevent the gates from closing but they are sometimes used to signal the gates to open. SEA produce standard plastic long range, slim line and battery systems, also offering solid aluminum anti-vandal units if required.
Vehicle Induction Loop Detector
Induction loops can be used for vehicla safety to provide 'hold open safety' or 'start' inputs to open the gate systems. They consist of a coil of cable (loop) set just below the drives' surface. The tails of this loop are wired back to the 'electronic detector unit'. When a vehicle passes over the loop, the metalwork of the passing vehicle causes the detector unit to change state and signal the automatic gate system to perform its programmed action.
Safety Edges
Contact strips with integral trigger wire and switch, these items are commonly used to provide safety on sliding gate systems. Safety edges react on contact with and obstruction and will stop and reverse the gate they are often combined with battery powered photocells or radio transmitters to protect the leading edge of sliding gates. Recommended for all gate danger areas which have been identified during risk assessment. EN12453 compliant.
Warning Lamps
A light with a blue or amber lens that provides warning of a gate's impending or actual movement. Long life LED versions available
Safety Gate
A patented safety device ideal for domestic swing gates that measures the speed of rotation, providing greater levels of safety particularly where pedestrian access is required. This device can be fitted to any type of SEA mains operators providing stop and reverse safety, acting as if there were safety edges fitted all over the gates. This Safety Gate can assist in compliance with the European safety regulations EN12453 and EN12455; please contact us for further information.
