Setting Up
The Ambient Noise Sensing function is controlled either from the BVR20 front panel, or a
Laptop Computer if the Configuration software is fitted. The following identifies the BVR20
LCD screens, and assumes that the user has access authority.
With the System Configuration Keyswitch in the ON position, press the PAGE DOWN key,
the first page will identify the software version of the BVR20. Press PAGE DOWN again and
enter User Code , press PAGE DOWN until you come to the first of the output pages, (fig 2).

Before setting the ANS level it is important to establish two points
1. Set the maximum output volume required in the ANS zone, that is the volume demanded
to meet a fully populated area, or with maximum ambient noise i.e. a train waiting at the
platform.
2. That the figure entered for volume is within the limits 10 to 15 , this will allow the ANS
to enable a full dynamic movement of the output volume. It may be necessary to reduce
the associated input gain using the volume and attenuator controls on the
INPUT page.
The example below shows output volumes entered for Fire Microphone One, Message
One, and Message Two, (fig 3).
