- The key switch should be mounted at a convenient height for all users.
5.2. Prepare for Wiring
- WARNING: Before proceeding, ensure the power supply to your garage door operator is completely disconnected at the main breaker.
- Route the provided 2-meter, 2-wire connection cable from the key switch mounting location to your garage door operator's control unit. Ensure the cable is protected from damage.
5.3. Mount the Key Switch
- Position the key switch housing on the chosen surface.
- Mark the drilling points for the mounting screws.
- Drill pilot holes if necessary, using an appropriate drill bit for your wall material.
- Secure the key switch housing to the wall using the provided mounting hardware. Do not overtighten.
5.4. Connect to Garage Door Operator
- Connect the two wires from the key switch cable to the designated impulse input terminals on your garage door operator's control unit. Refer to your specific garage door operator's manual for precise wiring diagrams and terminal identification.
- Ensure all connections are tight and secure.
5.5. Test Operation

6. Operating Instructions
The Hormann ESA40 Key Switch provides a simple and secure method for operating your garage door:
- Insert one of the provided keys into the key cylinder of the ESA40 Key Switch.
- Turn the key. This action sends a momentary impulse signal to your garage door operator.
- The garage door will either open or close, depending on its current state.
- To stop the door mid-movement, turn the key again.
- Remove the key after use to maintain security.
Important: Do not leave the key in the switch when not in use to prevent unauthorized access.
7. Maintenance
Regular maintenance ensures the longevity and reliable operation of your key switch:
- Cleaning: Keep the key switch clean by wiping it with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Mounting Check: Periodically check the mounting screws for tightness. Retighten if necessary to ensure the unit remains securely fixed to the wall.
- Key Cylinder: Ensure the key cylinder operates smoothly. If it becomes stiff, a small amount of graphite lubricant (do not use oil-based lubricants) can be applied to the key and inserted into the cylinder.
- Cable Inspection: Inspect the connection cable regularly for any signs of wear, cuts, or damage. If any damage is found, disconnect power immediately and replace the cable or contact a qualified technician.
