A false obstruction message is usually caused by a dirty, misaligned or failing sensor, or by something reflective near the lane such as a polished panel or a stuck piece of tape. Dust on sensor windows is the most frequent cause. We clean and realign the sensors, check the cabling to them and test the lane with and without a person. If a sensor has failed it needs replacing.

If the card reader shows a valid read but the gate stays shut, the release signal may not be reaching the gate. Wiring faults, a failed relay, a configuration change or a gate in an error state can all cause it. We check the reader output, trace the signal into the gate controller and read any fault indication on the unit. We then test the lane with several cards.

An interlock holds a door shut when it thinks the other door is open or the chamber is occupied. A misaligned door contact, a stuck sensor or a door that is not fully closing can leave the logic in that state. Faulty wiring between the doors also causes it. We check each door position input, sensors and the control unit, then test the complete entry and exit sequence including emergency release.

First check whether the unit has power and shows a fault code or light. A stuck flap can mean a drive fault, a blocked mechanism, a worn bearing or a safety stop triggered by a sensor. Do not force the wing by hand. Report the symptoms, such as noise or partial movement, and a technician will inspect the drive, limit positions and sensors on site.

Tell us which lanes fail, what the display or lights show and whether faults happen at busy times. Arrange a quiet period so a lane can be closed, and inform reception and security. If the gates link to an access control system, have the person who manages it available. Note the model labels on each lane if they are easy to read.

A boom barrier is a long arm that rises vertically, controlling vehicle access without physically blocking the full width of the road when open, so it opens and closes in one to three seconds and handles high vehicle throughput well. A swing gate is a full panel that blocks the entire opening, giving more physical security but taking longer to cycle and needing more clearance space.

For a car park or compound with steady vehicle flow, a boom barrier paired with a loop detector and access control card reader is the standard setup. A swing or sliding gate makes more sense where you need a solid physical barrier after hours, not just traffic control.

Most boom barriers open in around 1 to 3 seconds, depending on the arm length and whether it is set for standard or fast operation. Faster cycling models exist for high-traffic entrances like paid parking exits or logistics yards where queue length matters, though very fast cycling increases wear on the motor and gearbox over time.

We set barrier speed based on your traffic volume at survey, balancing throughput against component longevity rather than defaulting to the fastest setting for every site.

Standard barriers stop in the down or up position depending on where they were when power was lost, and most have a manual release lever that lets security staff physically lift the arm to let vehicles through. A backup battery is available as an add-on that keeps the barrier operating automatically for a limited time during an outage.

For sites where an obstructed exit during a power cut is a real safety concern, like a busy car park, we recommend the manual release be tested regularly as part of routine maintenance, not just installed and forgotten.
