Wall-Mount Voice Evacuation System

VX-3308WM

The VX-3308WM is a device designed to control the Voice evacuation announcements of TOA's VX- 3000 Series wall-mount type voice evacuation system which is compliant with the European StandardEN54 for fire alarm systems. It is possible to make an Emergency Warning Broadcast assigned a higher priority than the Emergencybroadcast. Two patterns of the Emergency broadcast can be activated simultaneously. Compatible with network, the system can be configured in distributed arrangement.Features include the following functions: Digital signal processing function that enables appropriate acoustic adjustment for individual input sound sources and output amplifiers, Feedback suppressorfunction that automatically suppresses acoustic feedback when it occurs, VOX function that allows start/stop control of broadcast by way of an audio trigger, and ANC function that enables an ambient noise control. (The ANC function distinguishes between the unit's output sound and the ambient noise. The unit's output sound is not detected as noise.) Indicators that show such statuses as fault status and power amplifier signal status are provided.It has 8 speaker output channels.A total of 3 power amplifier modules (2 for zone amplifier use and 1 for standby amplifier use) can bemounted. Equipped with a matrix output the VX-3308WM can be used as 2-bus speaker selector using2 power amplifiers. Setting the matrix output destination makes 1-bus and 2-bus zones coexist. Zones can be expanded by connecting the unit having amplifier module(s) and the one having no amplifier module.
