VoiceOff Alarm Activated MP3 Message Player

System Q Stand: 5/H150

VoiceOff is an affordable, professional hardware solution to play messages or sounds to welcome, warn or inform people.

It can be triggered to play one of its on-board MP3 sound files using a hard-wired trigger such as a door contact or PIR, by software, using its new network connection or via its RS485 input by interfacing it with an access control system.

The sound files are stored inside the VOX400 on a microSD card in MP3 format and the local file storage means messages are played instantly without any network delay. These sound files can be messages, alarm sounds, music or a mixture of all of them. You then can trigger the VoiceOFF to play the appropriate message or sound depending on your application, it can store and play 10K individual sound files making it more than capable of the most demanding installs.

A shop might use the VOX400 for example to play a welcome and special offer messages, an industrial unit may have a VOX400 in a yard area warning off intruders at night by saying
