Automated gates provide convenience and security, but they also pose potential hazards if not properly equipped with safety devices. Understanding these features helps you maintain a safe system for your family and visitors.
Required Safety Devices
Photo Eyes (Photoelectric Sensors)
Photo eyes create an invisible beam across the gate opening. When something breaks the beam, the gate stops or reverses.
- Placement: Typically installed 6 inches and 24 inches above ground
- Function: Detects people, animals, and vehicles in the gate path
- Maintenance: Keep lenses clean and aligned
Edge Sensors
Pressure-sensitive strips attach to gate edges and detect contact with objects or people.
- Leading edge: On the edge that contacts the closing point
- Reversing edge: Triggers immediate reversal on contact
Auto-Reverse
When the operator senses resistance during closing, it automatically reverses direction. This feature uses:
- Current sensing: Detects motor strain from obstruction
- Encoder feedback: Monitors gate position and movement
Additional Safety Features
Manual Release
Every gate operator must have a manual release allowing the gate to be opened during power outages or emergencies. Know where yours is located and how to use it.
Warning Signs
UL 325 requirements mandate warning signs on automated gates informing users of potential hazards and emergency procedures.
Timer-to-Close
Gates can be programmed to automatically close after a set time, but this feature must work with safety sensors to prevent closing on obstructions.
Safety Standards
Gate operators sold in the US must meet UL 325 safety standards. When hiring an installer, verify they:
- Install UL-listed equipment
- Include all required safety devices
- Test safety features during installation
- Provide documentation of safety compliance
Maintaining Safety Systems
Regular testing keeps safety devices functioning properly:
- Test photo eyes monthly by blocking the beam during gate operation
- Test edge sensors by applying light pressure during closing
- Verify auto-reverse by placing an obstruction in the gate path
- Check warning signs for visibility and legibility
