Automatic Gate Safety Requirements (UL 325) Explained

The Short Answer

Yes — automatic gates are required to have safety devices, not just a working motor. UL 325 is the safety standard that governs automatic gate operators in the US, and it requires at least two independent entrapment-protection devices in each direction the gate travels. A gate opener without these isn't just a bad idea — on new installs, it's non-compliant.

What This Means For Your Gate

• Installing a new gate: every install we do includes the required safety devices as standard, not an optional add-on.
• Automating an existing manual gate: a retrofit isn't complete until it has compliant sensors, even if the gate itself is older.
• Buying a property with an existing automatic gate: older gates, especially DIY or unlicensed installs, often lack proper entrapment protection. We can inspect an existing gate and tell you plainly whether it's compliant.
• A gate that suddenly stopped working: if your gate won't operate at all, a disconnected or failed safety sensor is one of the most common causes — the system is doing exactly what it's supposed to do.
