Although the EN54 fire evacuation standard has been in place for some years now, its varied rate of adoption around the world means that the market for EN54-rated voice alarm equipment is still rising.
TOA system is flexible and scalable
TOA describes its VX-3000 as a cost-effective, robust, reliable and energy-efficient system, which combines all of the important functions for public address and voice alarm in a single unit.
The VX-3000 uses modular Class D amplifiers, with a choice of 150W, 300W and 500W output ratings. These can easily be removed or replaced simply by unplugging them; there is no need for specialist tools. Using these low-loss amplifiers in conjunction with modern power supply switching technology makes the system highly energy-efficient.
The system is flexible and scalable, so can be used for applications of all sizes, up to 256 remote microphones and 128 audio sources.
Other components include a remote microphone, a remote key extension (which adds 10 more buttons to the remote mic), a fireman’s mic, and EN54-compliant high-intelligibility horn speakers. The limited number of components is said to simplify design and installation, save space, reduce cable complexity, and enable rapid system configuration.
A compact wall-mounted version of the system can either be used as a standalone unit in reception areas and building entrances, or linked to the standard VX-3000 range.
