Setup Instructions

VIGIL BVR20 - MICRODRIVE
The BVR20 (Microdrive) is the heart of the Voice Alarm system that accepts all of the audio inputs
and provides the outputs for the whole voice alarm system. Up to 20 audio inputs can be routed
through to up to 20 outputs (zones) in any configuration. The inputs range from any microphone or
line level source to the emergency messages and background music.
The system is modular, and depending on the system requirements different modules are plugged into
the rear of the BVR20.
BVR20 Modules & Brief description of Functions and Features
Module Function
BVRCPU CPU and PSU card: one per BVR20
BVRI4 Quad line input (each with attenuator, compressor, limiter, 5 band equ & chime control)
BVR802 Quad Digital message card, accepts up to 4 OPT402 modules
BVRO2 Dual line output card (each with 6 band equ and option socket for further EQ module)
BVRIO40 40 parallel inputs for zonal access, monitoring, fault i/p & o/p, changeover etc
BVRACO Control interface for faulty amplifier changeover
BVRNCO Control interface for when automatic changeover is not required
BVRCI Control interface for universal zonal access switching, with Ambient noise option
BVRAIO Control interface for Fire Alarm Panel
BVRL20 20 way 3 metre ribbon cable for connecting cards and interface modules
BVRL26 26 way 3 metre ribbon cable for connecting cards and interface modules
The BVR20 provides all of the monitoring functions and displays the system status using a 40 x 2
character LCD display and 5 front panel mounted LEDs.
The unit can be operated in two separate modes depending on the position of the front panel key-
switch.
Under ‘Normal’ operating conditions (i.e. the key is not turned) all advanced functions of the BVR20
are barred to prevent unauthorised changes to the system. The only options available are monitoring
input and output signals through the internal loudspeaker, and viewing the system status pages which
can be scrolled up or down to display the status of the monitored items in the Voice Alarm system.
If the ‘System Configuration’ key-switch is turned the unit is in System Configuration mode and all
functions of the BVR20 can be changed.
The functionality of the Voice Alarm System can be altered in this mode.
As incorrect use of this mode could prevent an Alarm Condition from being detected
we strongly suggest that this mode is not entered unless the user is fully aware of the
system configuration.
If changes are to be made in this mode please refer to the relevant pages of this manual on how to
achieve the changes required.
To discourage leaving the unit in “System Configuration” mode the key cannot be removed from the
switch until it is returned to the “Normal” position.
When the unit is first powered up, various settings and controls will require setting up in the
“Configuration” Mode.
Once these have been set, the internal memory will hold this information. Should mains and/or battery
power loss occur, the settings will remain in the memory.

This will also prevent the associated sensor fault being announced.
When the maximum levels have been set, using the + key slowly increase the value until the

loudspeaker level follows the ambient noise.
In theory, if the ambient noise is at its loudest, the announcements should remain around 10dB
above the ambient level. The sensitivity is adjustable from 01 and 15. Once set, the loudspeaker
volume will automatically adjust to the ambient noise in that zone, from maximum and 20dB
below maximum. Therefore if the sensor does not sense a signal, the output will be 20dB below
the maximum setting.

The maximum input sensitivity without attenuation is 80mV (-20dBM). However the gain may be
reduced using a fine and coarse attenuator.
The fine provides 15dB of attenuation in approximately 1dB steps and the coarse provides 30 dB
in 2dB steps. Setting the attenuator correctly will prevent overloading the input stage and easier
adjustment of the system.
If an input of 775mV (0dBm) is required than simply attenuate the input by 20dB by setting the
coarse to 09.
To set the input attenuator, move the cursor along until it flashes beneath the desired attenuator

On both ports the TX and RX addresses are independently set. In most applications both the TX
and RX are required to be set to the same address. This address only allows data intended for the
BVR20 to be processed, thus identifying an individual BVR20 when several (maximum 8) are
connected to a BVAMC control microphone.
If only 1 BVR20 is connected to a BVAMC, the address, both TX and RX is set to 01.
If 2 are connected, 1 of the BVR20 is set to 01 and the other is set to 02 and so on for the
maximum of 8.
Port 1 serves Fire microphone 2 on audio input 2 and port 2 serves Fire microphone 4 on audio
input 4.

MAINTENANCE OF THE BVR20
If a fault is suspected on any of the BVR20 modules, simple substitution with a spare can be carried out as first-
line maintenance. Before removing any module ensure that the two DC supplies are disconnected by removing
the lower 8-way blue plug from the CPU module. The CPU module BVRCPU – as viewed from the rear – is
located at the extreme right hand side, position 21.
Carefully remove all connectors to the suspected module with a small posi-drive screwdriver, release the two
retaining screws at the rear of the module and, observing electro-static precautions, carefully remove the
module. To replace the module, carefully slide in the new module, fasten it using the two screws, replace the
connectors and now you are ready to apply power. Please ensure that the correct module has been fitted in the
correct position.
The heart of the BVR20 is the CPU module – BVRCPU - which controls all the input and output routeing,
together with all monitoring facilities. Please note this module must only be fitted in position 21, at the extreme
right hand side of the BVR20.
As a simple guide to fault finding, should one zone output be faulty then it would be true to suspect the output
card serving that zone – especially if the other channel is operating.
Input modules – BVRI4 - have four inputs, each with a maximum sensitivity of -20dBm (approximately
80mV), which is amplified and presented to the audio bus structure at 0 dBm (approximately 800mV).
The message module –BVR802 – has the facility for four messages and provides 20 opto isolated inputs to
interface with fire detection panel sounder circuits. Again the signal from each message is presented to the
audio bus at 0dBm. The system monitors the audio output presented to the first output module and the DC bias
present at the output of the digital-to-analogue converter, which is displayed as a memory fault.
The dual output card –BVR02 – has two line outputs of 0dBm and provides frequency equalisation and gating
from all the 20 input signals. This module also provides volt-free relay contacts, which change condition when
the zone is busy.
On the system there are two signal input/output cards – the BVRIO40 which, in conjunction with the interface
cards – the BVRACO, monitor the external loudspeaker lines using the BEL1 end of line unit. The BVRACO
also provides automatic changeover in the event of a faulty amplifier to a reserve. The module positioned in
P18 serves all the ‘A’ circuits, whilst the one fitted to P19 serves all the ‘B’ circuits. Input signals for the
reserve amplifiers are obtained from output modules plugged into P16 and P17 and automatically, in the event
of an amplifier failure, route the correct source of signals to the relevant reserve amplifier.
All of the BVR20 modules are fed from a dual supply line unregulated and regulation is provided on each
module. The supply input to each card is protected by a poly-switch self-resetable fuse and, in the case of the
CPU, a dual regulator path is provided.
Please note: Under no circumstances remove or replace a module with the power supply connected.
Should a faulty module be discovered, repair can only be accomplished in an equipped workshop. Therefore,
we recommend that first-line maintenance is only by replacing modules from a spares stock.
