When most people think about an automatic gate, they focus on the motor itself. However, one of the most important safety features of any automatic gate system is a set of Safety Infrared (IR) Beams.
Whether you're installing a residential driveway gate, a rural farm entrance, or a commercial access system, safety beams provide an additional layer of protection for your family, visitors, vehicles, pets, and property.
What Are Safety IR Beams?
Safety IR Beams consist of a transmitter and receiver mounted on opposite sides of the gate opening.
The transmitter sends an invisible infrared beam across the gateway to the receiver. When a vehicle, person, animal, or other object interrupts this beam, the gate controller is alerted to the presence of an object within the opening.
This allows the gate system to prevent closing or stop operation until the opening is clear.
Why Are Safety Beams Important?
Automatic gates can be heavy and powerful. While modern gate operators include various safety features, IR beams provide an additional level of protection that helps prevent accidental gate movement when an obstruction is present.
Safety beams are particularly valuable when:
- Auto-close functionality is enabled
- Children regularly use the property
- Pets may access the driveway area
- Visitors are unfamiliar with the gate operation
- Larger vehicles require additional time to clear the entrance
- Farm machinery, horse floats, caravans, or trailers regularly use the gate
Protecting Vehicles and Equipment
One of the most common situations occurs when a vehicle has not fully cleared the gateway before the gate attempts to close.
This can be especially relevant for:
- Caravans
- Boat trailers
- Horse floats
- Farm machinery
- Trucks and delivery vehicles
Safety IR Beams help ensure the gate remains open while the vehicle is still within the opening.
Improving Safety for Families and Pets
Many property owners choose automatic gates to improve security and privacy. Safety beams complement this by helping protect the people and animals using the property.
If a child, pet, or visitor passes through the gateway while the gate is operating, the beam system can detect their presence and prevent the gate from closing.
Recommended for Auto-Close Installations
Auto-close functionality is a convenient feature that automatically closes the gate after a preset period.
However, auto-close systems rely on the gate being able to determine whether the opening is clear.
For this reason, Safety IR Beams are strongly recommended whenever automatic closing is enabled.
Choosing the Right Safety Beam
Different gate systems require different beam options.
Merlin Gate Systems
Merlin Safety IR Beams provide reliable obstruction detection for compatible Merlin gate operators. Hooded reflector options are also available for exposed installations requiring additional weather protection.
DACE Gate Systems
DACE DuraOptics Photo Eye Beams are available in both wired and wireless configurations and are compatible with a range of DACE sliding and swing gate operators.
SolarTronics Gate Systems
SolarTronics Photo Electric Sensors are designed to improve safety by detecting vehicles and objects within the gate opening and are particularly useful for larger vehicles, machinery, trailers, and rural properties.
Final Thoughts
While gate motors often receive the most attention, Safety IR Beams are one of the most valuable accessories you can add to an automatic gate system.
They help protect people, pets, vehicles, and equipment while improving the overall safety and operation of the gate.
For most installations, especially those using auto-close functionality, Safety IR Beams should be considered an essential component rather than an optional extra.
