VoiceOFF MK2 - Programmable Audio Alarm Code: VOX200 MK2
What can be used to trigger the Voice ff unit?
The VoiceOff is triggered by simply connecting any of its alarm input terminals to ground or zero volts. Obviously you can do
this using a piece of wire and simply connect the alarm terminal to ground but most people want to do this automatically. For
example when a person walks through a doorway, the VoiceOff is triggered and a message starts playing.
To do this you have quite a few options. By fitting a “magnetic door contact” to the door you can use it to automatically
connect to one of the VoiceOff’s alarm inputs to ground and start VoiceOff playing back that corresponding audio file when the
door opens. You will need a door contact that has what’s called “normally open” contacts, these are readily available items.
Similarly, you could use a movement detector such as PIR. Again, when the PIR detects movement you will use its “normally
open” contacts to connect one of the VoiceOff's alarm inputs to ground. This in turn makes the VoiceOff start playing the
related audio file, be it a welcome message, a warning or something else perhaps a barking dog!
Other devices can be used to trigger the VoiceOff, these includes Digital Video Recorders, burglar alarm panels, bell boxes,
key fobs and so on. Almost every one has a different way of triggering the VoiceOff and what it is used for.
Instead of having a burglar alarm with just a siren why not have an additional sounder that tells passers by to call the police or
another telephone number?
What happens when more than one alarm is triggered in quick succession?
A common question people ask about the VoiceOff is “what happens if its playing back one message and another alarm input or
perhaps the same alarm input is re-triggered?” The answer is the original message plays out until it reaches the end of that
message. This is a deliberate feature. Its so that if you are using a VoiceOff unit to warn away intruders and a message is played
when a PIR detects the intruder you want the message to complete even if the PIR is re-triggered by movement again. If this did
not happen, the warning would sound a bit fake especially if it’s cut off midway through and restarts again. Ideally you want
the listener to believe its possible (even if only at a subconscious level) that a real person is delivering the message. Similarly
you may be using the VoiceOff to deliver a welcome message, you will want the welcome message to play out in full and not be
cut off midway through delivery because the unit is re-triggered by someone else.
Over time, some of the more unusual uses will be published on the VoiceOff website to show the ingenuity people have. The
