Safety Photocells
Safety photocells are an important part of an automatic gate safety system. Installed in suitable positions around the entrance, they use a photoelectric beam or manufacturer-specific detection arrangement to identify the presence of a vehicle, person or obstruction within the protected area and communicate that condition to the gate controller.
A photocell does not physically stop a gate by itself. It sends a safety input to the automation control board, which then responds according to its programmed logic. Depending on the gate system and operating phase, this may prevent closing, stop movement or cause the gate to reopen.
AZTÖR installs safety photocells for automatic sliding gates, swing gates, cantilever gates, folding and bi-folding gates, trackless gates and suitable heavy-duty commercial or industrial gate systems. The number and position of photocells are determined by the gate movement, entrance geometry and required safety arrangement rather than simply installing one pair at every site.
For sliding gates, photocells can help protect the vehicle passage and closing area. Additional protection may be required around other hazardous movement zones, particularly where a sliding gate travels beside a wall, fence or accessible area.
Swing gates require careful consideration because each leaf moves through a large arc. Photocell positioning should reflect the actual sweep of the gate, vehicle stopping position, pedestrian movement and whether the leaves open inward or outward.
Correct alignment is essential. A photocell transmitter and receiver must maintain reliable communication, while reflective systems require the appropriate reflector arrangement. Poor mounting, unstable posts, incorrect alignment, damaged wiring or unsuitable positioning can lead to intermittent gate faults.
Outdoor gate photocells in the UAE are exposed to heat, dust, sand and direct sunlight. Product selection and installation therefore need to consider the manufacturer's environmental rating, operating temperature, enclosure design and actual mounting location. Regular cleaning is also important because contamination can interfere with optical performance.
AZTÖR works with compatible safety accessories from established gate automation manufacturers such as FAAC, CAME, BFT, Nice and Benincà, together with other suitable systems used in UAE and GCC gate installations. Where an existing gate uses another brand, compatibility with its control board is checked before replacement.
Wired photocells are commonly used where suitable cabling is available. Depending on the selected automation platform, wireless or simplified installation options may also be available for applications where running new cables is difficult. The appropriate solution depends on the gate controller and manufacturer.
Safety photocells should not be treated as the only protection required for every automatic gate. Depending on the gate design and risk areas, photocells may need to work together with safety edges, obstacle detection, vehicle loops, warning devices and appropriate control settings.
AZTÖR also troubleshoots existing gate photocell faults. Typical symptoms include a gate that refuses to close, closes only in manual mode, reopens unexpectedly, stops intermittently or shows a safety-input fault. We inspect alignment, lenses, wiring, power supply, terminals, control-board inputs and the photocell itself before recommending replacement.
Bypassing a faulty safety photocell simply to keep an automatic gate operating can remove an important protective function. AZTÖR recommends identifying and correcting the fault rather than permanently disabling a safety device.
AZTÖR provides gate safety photocell installation, replacement, alignment, repair and preventive maintenance across Dubai, Abu Dhabi, Sharjah, Ajman, Ras Al Khaimah, Fujairah and Umm Al Quwain, with suitable gate automation support available across the wider GCC.

Photocell quantity, type and mounting position must be determined from the actual gate movement and entrance layout. A single pair of photocells should not automatically be assumed to protect every potential hazard area. AZTÖR checks the gate type, opening and closing movement, vehicle path, pedestrian exposure, controller compatibility and existing safety devices during a free site inspection before confirming the appropriate arrangement.
