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)

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.

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 routing, 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 max sensitivity of -20dBm ( 80mV),
which is amplified and presented to the audio bus structure at 0 dBm ( 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 units. 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 an unregulated dual supply line and regulation is
provided on each module. The supply input to each card is protected by a poly-switch self-
resettable 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 carried out by replacing
modules from a spares stock.
If the system has automatic changeover it will be necessary to press the ‘CPU Restart’
on front panel when the faulty amplifier is replaced.

FAULT REPORTING AND STATUS PAGES
(Available in “normal” mode i.e. without turning the “system configuration” key.)
In normal operation mode this unit indicates the condition of the system via the front panel
display. Under normal - i.e. non-fault - conditions the green healthy indicator will illuminate,
the fault relay will be energised and the sounder will be silent.
A fault is indicated by the flashing yellow “Common Fault” indicators, together with the
sounder, sounding 1 second on, 1 second off. By pressing the “Fault Accept” button the fault
indicator will illuminate continuously and the sounder will be silent. Separate yellow
indicators are used for CPU Fault and CPU Restart. Pressing the “Lamp Test” button checks
all the “Fault” indicators.
Note: Operation of the “Fault Accept” button does not affect the fault output
produced by the relay contacts to external equipment i.e. Fire detection panel.
The various status pages are scrolled up and down with the “Page Up” and “Page Down”
keys.
Faults are shown by “XX” in place of “OK” ,lower case “ok” shows a fault has occurred and
cleared. This is useful to show where intermittent faults have been ,to reset operate key
switch momentarily.
The pages are displayed in the following order:

Note:
Surveillance for inputs 1-9 is sampled from output 1 and therefore associated inputs on
output 1 must be set to a value greater than 05 to prevent input audio faults.
Surveillance for inputs 10-16 is sampled from outputs 2-8 respectfully, i.e. input 10 from
output 2, input 16 from output 8 and therefore the associated inputs on the relevant
outputs must be set to a value greater than 05 to prevent input audio faults.
Each output channel has an independent adjustment for the volume level from each input
channel.

Move the cursor along until it flashes beneath the sensor window, shown above.
If ambient noise sensing is not required or the maximum output is being set, press 0 to
disable it. 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.

If this input channel is used for an emergency message or microphone the signal path
should be under surveillance and mode 01 or 03 should be used. This will enable
associated input channel faults. Available on inputs 01-16 only.
Each output channel has a volt free change over relay contact that may be used to
operate external busy indicators but is only active when modes 02 or 03 are selected.
To set the mode. Move the cursor along until it flashes beneath the MODE window and
using the numbered keys enter your choice 0 to 3.

Page 18 IBVR20 software 8.43.doc Issue 1
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 window. Values between 0-9 may be entered directly using the numbered
keys. Note the cursor automatically steps to the next window. Or using the + or – keys will
increase or decrease the value between 00 (no attenuation) and 15 (maximum
attenuation)
Input dynamic compressor or limiter may be introduced to prevent overloading and
assists in maintaining a constant output volume if several operators use a microphone or
music with wide ranging levels..
