VA-2240WM 2 Zones Voice Evacuation Controller

Descriptions:
* 240W high-efficiency digital power amplifier built-in; 2 power A + B independent dual-speaker loop zone output; each zone has a separate LED indication, separate output control buttons, and a separate volume control.

• For playing any audio source in the zones, there are four audio balanced input ports.
• *PC software can be used to set up local emergency PTT microphone input and emergency voice to play in a certain zone.
• *Automatically determine each zone loop's operational status (fault, normal).
• The emergency speech preset by the PC software can be activated by the 4-channel trigger input/output port to the designated zone or by the corresponding external power source to the corresponding event alert.
• *Support emergency audio input from third parties (user-defined emergency audio source)
• *Integrated independent voice information player for EVAC/ALERT.
• *The web interface for the remote paging and fireman microphones allows connections to both devices.
• Each paging station is connected via a conventional RJ-45 network socket and CAT-5 network cable, and voice transmission over long distances is done using balanced transmission mode.
• *The slave unit can be connected to the controller online interface using a regular CAT-5 network cable and RJ-45 network connector.
• *communication interface, which offers visual interface operation based on the Windows platform and allows for automated synchronisation of system status.
• *Attain DC24V battery backup power supply.
• *With a monitoring function for power amplifiers.
• *PTT recording capability supported; no additional equipment needed.
• *System error, output for emergency status on dry contacts, and input for emergency status reset on dry contacts
• *The three-wire and four-wire overriding adjustment options are available for the zone output.
• *With impedance calibration and IP address reset functions.
• *The master-slave unit is integrated, and by setting the code address, the device may be used as a controller or a slave unit. A maximum of 19 slaves can be online at once.
• *The system can support a maximum of 40 zones, which can be increased by slave units.
