4. Installation and Setup
4.1. Pre-Installation Checks
- Verify that all components are present and undamaged.
- Ensure the mounting surface is flat, stable, and suitable for surface mounting.
- Confirm that the power supply to the gate or access system is disconnected.

- Mark the drilling points on the mounting surface using the key selector's base as a template.
- Drill pilot holes at the marked points.
- Secure the key selector base to the surface using appropriate screws and fasteners (not included).
4.3. Wiring Connections
- Route the necessary control cables through the designated entry points on the key selector's housing.
- Connect the control wires to the screw terminals inside the key selector. Refer to the wiring diagram provided with your gate or access system control unit for specific connections. The key selector typically acts as a momentary contact switch.
- Ensure all connections are tight and secure.
- Close the key selector housing, ensuring it is properly sealed.
4.4. Post-Installation

- Test the key selector's functionality as described in the Operating Instructions section.
5. Operating Instructions
The BFT P121011 Intro Key Selector provides a simple, key-operated control for your access system.
- Insert Key: Insert the provided key into the keyhole on the front of the selector.
- Activate: Turn the key to the desired position (e.g., 'A' or 'B' if multiple functions are supported, or simply to activate the single function). The key selector is designed to provide a momentary contact closure, which signals the connected control unit to perform an action (e.g., open/close gate).
- Return Key: After activation, return the key to the '0' (neutral) position and remove it. The key selector will return to its normally closed state.
The specific action triggered by turning the key (e.g., opening, closing, or stopping a gate) depends on how the key selector is wired to the main control unit of your access system.
6. Maintenance
Regular maintenance ensures the longevity and reliable operation of your BFT P121011 Intro Key Selector.
- Cleaning: Periodically clean the exterior of the key selector with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Keyhole Inspection: Ensure the keyhole remains free of debris. If necessary, use a small, soft brush to clear any obstructions. Avoid using lubricants that may attract dust.
- Wiring Check: Annually, or if issues arise, disconnect power and inspect the wiring connections inside the unit for any signs of corrosion or loosening. Re-tighten connections as needed.
- Key Condition: Inspect the keys for wear or damage. Worn keys may not operate the selector smoothly or reliably.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Key selector does not activate the system. | No power to the control unit. Incorrect wiring. Faulty key selector contacts. |
Check power supply to the main control unit. Verify wiring connections against the system's diagram. Test the key selector's contacts with a multimeter. Replace if faulty. |
