2. Safety Information
This gate operator is designed with multiple safety features to protect users and property. Adherence to all safety guidelines is crucial for proper operation.
- Gate Safety Sensors: These sensors are designed to detect obstructions in the gate's path, preventing the gate from closing on people or objects.
- Security+ 2.0: This technology safeguards access to the property by utilizing an encrypted signal, offering enhanced security and extended range.
- Safety Reversing: If an obstruction is detected, the gate will reverse its direction. This feature works in conjunction with the inherent reversing sensor and included monitored safety accessories.
- Quick Close Feature: This function allows the gate to close rapidly after a vehicle passes, helping to prevent unauthorized access or "tailgating."
- UL Listed: The RSL12U has been tested and certified to meet the stringent UL 325 industry guidelines for gate operators. It is important to note that secondary entrapment devices (such as photo eyes or edge sensors) must be added to meet full UL325 standards for a complete installation.
- Sync Feature: This allows for synchronized gate operation, which can eliminate the need for costly trenching for wiring between two operators. Independent speed settings are also possible.
