Designed specifically for the VoiceOff unit it simply adds an extra speaker to your unit allowing you to cover a larger area.
The new Voice Off can be triggered to play stored MP3 sound files using a hard-wired trigger such as a door contact or PIR or by software, using its new network connection or even by its RS485 input with an access control system.
The VoiceOFF "VOX111" is a great way to automatically play pre-recorded messages to visitors at your business.
