VoiceOff FAQ

Can I adjust the unit's volume control?

The VoiceOff has a volume control that is set on installation to match the site requirements. For example, if you are installing the unit to play warning messages to deter unwanted visitors from a secure parking lot, you may want the volume on maximum as you want those intruders to hear your message loud and clear!

However, if you are installing the VoiceOff to play in-store promotions in a supermarket, you want the volume turned quite low so the message can just be heard, almost subliminal so as to not annoy the customer but perhaps help direct their buying choices of what's on offer that particular day!

The VoiceOff volume control settings are for engineer use only and not for general operation, so please refer to the installation manual supplied with the product at purchase.

When you receive the VoiceOff unit, the volume levels will have already been adjusted to a mid way point to suit most applications, so if it sounds right when you get it out of the box why not leave it at that setting.

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. It's 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 it's 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.

You may have a special or different use for the VoiceOff that does indeed require instant termination of any message that is playing. Of course, provision is proved for this with a “re-set” terminal. When you connect the re-set terminal to ground, the message is instantly terminated.

When you are using the VoiceOff to play back pre-recorded messages and also using its audio input to deliver live audio through its audio input connector, it is designed to take control over the system automatically.

For example, if audio is fed into the phono input any pre-recorded message that is playing will be terminated as the operator has chosen to take control and deliver live audio. This may be a supermarket announcing the store is closing in fifteen minutes using a microphone in the manager's office. The manager's message must obviously take precedence over any other action the VoiceOff is carrying out and therefore it would interrupt any MP3 audio that is playing from the SD card.

What can be used to trigger the VoiceOff 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 10 alarm inputs to ground and start the 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?

The new MK2 VoiceOff has a RS232 connection. Using the RS232, you can connect a PC or DVR to trigger up to 9999 sounds.

Can I add an extra speaker to the VoiceOff unit?
Yes, The VOX120 is a slave speaker for the VoiceOff Unit and you can fit up to 4 of these.
Can I fit the VoiceOff unit outside?

How many sound files can I add to the VoiceOff unit?

For the MK2 VoiceOff, a maximum of 9999 recordings can be added to the VoiceOff to use with the RS232 interface or 20 recordings for to correspond with the unit's 20 alarm inputs.
