EVAC-5245E Voice Evacuation System Expansion Unit (4 Zones, 1000W)

The LYINTL EVAC-5425E is a professional 4-zone voice evacuation expansion amplifier designed for large-scale emergency voice alarm and public address systems. It works as an extension unit for LYINTL evacuation system hosts, enabling scalable zone expansion up to 128 zones, making it suitable for complex and large building installations.

Equipped with a built-in 1000W main amplifier and 1000W backup amplifier, the EVAC-5425E ensures continuous and reliable operation in emergency situations. The system supports automatic amplifier fault detection and seamless switching, guaranteeing uninterrupted voice evacuation broadcasting when failures occur.

The unit provides 4 independent speaker zones, each with individual control and monitoring capabilities. Operators can expand system zones efficiently while maintaining centralized control through the main system. It supports paging to specific zones without interrupting background music, ensuring flexible daily operation and emergency communication.

Designed with advanced audio processing functions, the EVAC-5425E includes 2 balanced microphone inputs, 4 AUX inputs, and 1 AUX output, supporting flexible audio source integration. Independent master volume, treble, and bass adjustment allow precise sound tuning for different environments.

For system reliability, the EVAC-5425E integrates speaker line monitoring, detecting open circuit, short circuit, and normal conditions in real time. It also supports program source monitoring, system self-detection, and remote computer-based monitoring and control, ensuring full system transparency and maintainability.

The unit uses dual RJ45 network ports and CAN bus communication, supporting stable long-distance transmission up to 800 meters between host and extension units. With support for AC 220V and DC 24V backup power, the system ensures high reliability in critical emergency applications.

Additional professional control features include 100V bridge output, AB line output, zone volume control, address selection, and dry contact I/O triggers, making it a highly flexible solution for modern voice evacuation projects.
