8-zone 16-line expansion EN 54-16 EVA-3000 - RONDSON RON-02945

The EVA‑EXT3100 is the zone expansion unit of the EVA‑3000 series. It increases the number of loudspeaker lines and interfaces available in an EN 54‑16 certified voice evacuation and public address system. The unit provides 16 loudspeaker lines corresponding to 8 zones, 8 monitored contact inputs and 8 contact outputs, plus a line input for local audio sources.

Advanced automatic diagnostics supervise the power supplies, CPU, amplifiers, loudspeaker lines, contacts and network. If the controller CPU fails, the expander keeps distributing the audio present at the line input to all local zones, so operation continues during emergencies. It has audio outputs for the two channels CH1 and CH2 to connect external (including third-party) amplifiers, supports 3-wire and 4-wire volume controls, and offers a 24 VDC output to power auxiliary devices and accessories. Each zone can carry a load of up to 500 W, which makes the expander suitable for large installations. For the power amplifier interface the source quotes an output signal of 1.4 V.

Benefits: expansion by up to 8 additional zones with 16 loudspeaker lines; full integration with EVA‑3000 series PA / VA systems; automatic diagnostics on power supplies, CPU, amplifiers, lines, contacts and network; standalone operation for local announcements even if the controller fails; support for 3-wire and 4-wire volume controllers; 8 monitored contact inputs and 8 contact outputs to trigger external devices; CH1 / CH2 audio outputs for third-party amplifiers; 24 VDC output for accessories; load capacity of up to 500 W per zone; EN 54‑16 and CE/CB certifications.

Areas of use: EN 54‑16 certified voice evacuation and fire alarm systems; PA / VA systems in complex buildings with many zones; shopping centres, airports, hospitals, schools, hotels and offices; installations needing modular expansion of the audio zones; systems requiring continuous supervision and operational redundancy; integration with fire alarm control panels through the monitored contact inputs.

The technical characteristics are grouped as: line input, audio output, power amplifier interface, loudspeaker interface, contact input / output, others and working conditions.
