Automatic gates: safety, maintenance and the association’s liability

A powered gate is the only common area capable of injuring someone on its own. It deserves more than a contract signed once.

An automatic gate operates dozens of times a day for fifteen years, and nobody looks at it while it opens. The subject reaches the agenda when it fails on a Friday evening, or when a child, a bike or a car ends up in the wrong place at the wrong moment.

It is one of the few shared installations presenting a direct risk to people. Its safety is not a matter of opinion but of devices that are present and working.

The safety devices, and their real condition

• Photocells, stopping movement when an obstacle breaks the beam.
• Force detection, reversing the movement on contact.
• Protection against shearing and crushing at the dangerous points.
• Lighting or a warning light during movement.
• Manual release, essential in a power cut.

The first degrades invisibly: a photocell knocked out of alignment, dirty or masked by vegetation stops protecting, while the gate keeps operating normally.

The two-minute test

During the annual walk-through, two simple checks show whether the safety devices work: break the photocell beam while closing and confirm it stops immediately, then apply gentle resistance to the leaf and confirm the movement reverses.

These tests do not replace maintenance, but they immediately reveal a device out of service. They belong in the annual walk-through checklist, with the date of the check noted.

The maintenance contract

As with the lift, everything turns on what the contract really covers. Many buildings pay for annual maintenance that includes neither wear parts nor emergency call-outs.

• How many visits a year and what is checked each time.
• Adjustment of the safety devices, explicitly mentioned or not.
• Wear parts included: rollers, rack, springs, backup battery.
• Guaranteed response time on a blockage, and its cost outside the contract.
• A report issued after each visit.

The analysis is the same as for the lift and the cleaning contract: with no intervention report, the building pays without knowing what it buys.

Recurring failures nearly always share a cause

A gate that jams regularly rarely has an electronic problem: in most cases it is a cluttered rail, worn rollers, ground that has shifted, or a badly fixed photocell vibrating at every pass.

Logging each failure with its date reveals the pattern within months: see keeping an incident log. Three jams a quarter justify an overhaul, not another one-off call-out.

Access, the other half of the subject

A gate is only as good as control over the remotes that open it. Handsets distributed with no register, never deactivated after a sale or the end of a letting, drain the installation of its purpose.

See regaining control of access and letting a parking space, the first source of uncontrolled remotes.

A gate whose photocells no longer work still opens normally: that is exactly what makes it dangerous.
