Important: Installation must be performed by a qualified electrician. Ensure power is disconnected before beginning any wiring or mounting procedures.

6.1. Choosing a Location

Select a wall-mounted location that is:

• Within reach of the 220V power source.
• Clear of obstructions that might muffle the sound.
• On a sturdy surface capable of supporting the bell's weight.
• Protected from moisture and direct sunlight.

6.2. Mounting the Bell

1. Mark the desired mounting points on the wall using the bell's mounting bracket as a template.

6.3. Electrical Connection

The bell requires a 220V AC power supply. It is designed to be triggered by an external switch (not included).

1. Ensure the main power supply to the circuit is OFF at the breaker.
2. Locate the two red wires extending from the bell's control housing. These are the power input wires.
3. Connect these wires to your 220V AC power source, typically through a dedicated switch or alarm circuit. Ensure proper polarity if specified by your electrical system (though AC typically does not have strict polarity for simple loads).
4. Use appropriate wire connectors and ensure all connections are secure and insulated.
5. Once wiring is complete, carefully close the bell's housing.
