How to use

Install the rotary volume control on a suitable wall surface using appropriate screws and mounting hardware. Connect the audio input and output according to the system wiring diagram, ensuring the controller is rated appropriately for the connected amplifier and speaker load. Wire the 24 V emergency priority circuit so that an emergency signal can override the local volume when activated. Adjust the volume by turning the rotary knob to the desired level.

Recommendations

Ensure the controller is used within its rated power and voltage limits and that wiring complies with local electrical and safety regulations. For best performance, pair with compatible PA amplifiers and confirm that the emergency priority wiring is tested during installation.
