Impact SW

Think smart and combine battery charger capabilities with the integrated power amplifier

The DCA2.500 amplifier not only drives the system up to an impressive 1000 Watt, but it also charges and surveys a scalable battery pack up to three 1000 Watt amplifiers. It not only reduces hardware and rack-space, but most importantly, it decreases installation and operational costs whilst increasing reliability. Simple to configure with it’s easy to use GUI tool guiding software, you create a systems solution with multiple voice alarm zones, paging zones and music areas in minutes.

The DCA2.500 is a 2x500W transformer-less (direct-drive) 100V power amplifier with integrated power supply and 24V battery charger. It is designed and certified in full compliance with EN54-4 and EN54-16. DCA2.500 is an ideal component for a voice evacuation system or public address installation, where high reliability and safety is required.

The controller covers complete EN54-16 certified functionality, as well as a variety of features essential to public address applications. It incorporates 16 monitored contact inputs, 8 GPO, 4 relay outputs, 2 analogue audio inputs and 2 outputs. In addition, local network interfaces for max. 16 local peripheral devices (e.g. mic consoles) and 2 global network ports for interconnecting multiple systems in a redundant ring topology are included. The controller deals with inputs according to their own signal priority table, distributing the audio using the digital AMP-link module, which handles two prioritised audio streams through a dynamic assignment technique, to a maximum of 16 DCA-2.500 amplifiers per controller.

The controller is designed to work with 4EVAC DCA2.500 power amplifiers over a 4EVAC proprietary AMP link protocol. The controller can also be easily integrated with any third-party PA/VA power amplifier.

The controller-expander is an optional component of the 19” rack mounted Impact voice evacuation system. The controller-expander is identical to the Impact controller with significant hardware and functional limitations. Functionally, the controller-expander works as a network hub for additional L-net devices, such as microphone stations. In terms of interfacing, the controller-expander only features a DC power input and network ports (global network and local network).

The 4E-AM448 is a DIN-rail mounted amplifier surveillance module designed for Impact SW and MM systems. It provides intelligent monitoring and backup management for up to 4 amplifiers and 8 loudspeaker circuits.

AMP 1 | Line 1A | Line 1B
AMP 2 | Line 2A | Line 2B
AMP 3 | Line 3A | Line 3B
AMP 4 | Line 4A | Line 4B

Each of 8 loudspeaker output circuits is monitored individually.

• 4 Amplifier inputs and shared backup
  Each of the 4 primary amplifier inputs is paired with a shared backup amplifier input for maximum reliability 2000 watts per module with additional shared backup
• 8 Individually monitored loudspeaker circuits
  Every channel is split into A/B circuits for enhanced line surveillance and redundancy:
• AMP 1 → Line 1A | Line 1B
• AMP 2 → Line 2A | Line 2B
• AMP 3 → Line 3A | Line 3B
• AMP 4 → Line 4A | Line 4B
• Seamless integration
  Works with Impact SW and MM systems, ensuring flexible deployment across different configurations.

The 4E-AM448 guarantees continuous system integrity , combining surveillance, backup routing, and compliance in a compact DIN-rail design.

4EVAC Manager is an overall programming application tool, that provides a comprehensive interface for the Impact and Compact 500 networked systems. The software provides an overview of your overall system status and makes system operation very easy through an intuitive and secure user interface configuration tool that makes complex programming and service easier than ever.

The 4EVAC Manager programming application for the Impact and Compact 500 systems, provides:

• quick download and upload of the system configuration;
• updates of firmware and configuration over the network to all devices. Each controller or Compact 500 holds a complete copy of the system configuration file;
• flashcard exchange protocol for quick system updates and programming, in case of computer access disability or emergency purpose.

4E-SW6 is a DIN-rail mounted 100V audio matrix with 2 inputs and 6 outputs, dedicated for both 4EVAC Compact and Impact systems. 4E-SW6 has two 100V audio inputs (CHA, CHB) which connect directly to amplifier outputs. 4E-SW6 expands the number of independent loudspeaker lines with individual surveillance and short-circuit isolator units (Loopdrive). Each loudspeaker line can handle up to 200 W load and can be assigned as a separate individual zone. One input can accept maximum 500 W of power. This is also the limit for a total load of all 6 output lines together.

The 4E-SW6-LITE has been developed to be used with Loopdrive LDB on the outputs only.

4EVAC's GPIO is a din-rail mounted I/O interface with input surveillance and a redundant network link, dedicated to the 4EVAC system network. It features programmable 16 in / 16 out pins, mandatory EVAC and FAULT status output contacts, a monitored analogue audio input and a monitored RS-485 interface for integration with third-party external control panels.

The EN54-16 and EN54-4 standard certified, lightweight DCA2.500 D-Class amplifier provides powerful audio amplification. It delivers 2x 500 W outputs and is housed in a 2U 19" rack housing. Multiple DCA2.500 amplifiers can be stacked together, sharing a single battery pack, providing back-up power and collective recharging capabilities.

The amplifier has been designed along ‘modern-art’ lines and features a transformerless design with a direct 100 V output for distributed loudspeaker systems, and also drives into a low-impedance source from 8ohm and up. With its cutting-edge design, the DCA2.500 sets a standard for the most demanding projects and audio architectures.

Each DCA2.500 is equipped with a powerful 4A battery charger, capable of charging into a single 100Ah battery set.

A master/slave system architecture, dictated by the AMP link, regulates the battery cluster charging procedure and status control. This way a single, larger battery pack can be shared with multiple amplifiers.
