Rondson - EVA-EXT3100

The EVA‑EXT3100 is the EVA‑3000 series zone expander, designed to increase the number of speaker lines and interfaces available within an EN 54‑16 certified voice evacuation and public address system.

The device provides 16 speaker lines corresponding to 8 zones, 8 monitored contact inputs and 8 contact outputs, as well as a line input for local audio sources.

The EVA‑EXT3100 integrates advanced automatic diagnostics, monitoring power supplies, CPU, amplifiers, speaker lines, contacts, and the network. In the event of a controller CPU failure, the unit can still distribute audio from the line input to all local zones, ensuring operational continuity during emergencies.

It also features audio outputs for both channels (CH1 and CH2) for connection to external amplifiers, support for 3- and 4-wire volume controls, and a 24 V_DC output for powering auxiliary devices. Each zone supports up to 500 W of load, making the expander suitable for large systems.
