C 5 volume controller is designed for 5 W audio lines, making it ideal for background music and voice evacuation systems where local sound level control is required. Each unit features 10-step attenuation and includes built-in 24V internal emergency relay with an internal switch, allowing the controller to be used in either passive or active mode. Its improved construction design ensures optimal user mounting experience, with top panel installation requiring no additional tools or screws.

These controllers are compatible exclusively with CboxD mounting boxes, which can be ordered separately.
