Installation Instructions
BVRD Series Microphones issue 5 1
1 Introduction
The BVRD Series Microphones have been designed to provide a
wide variety of features suitable for any installation.
Figure 1.1 — Typical BVRD8 Microphone
The Microphones are configured during commissioning via an
internal USB port and communicate with the main control system
via an RS485 serial data link. A standard RJ45 Network cable
connection (carrying both Audio and Serial Data) is employed,
considerably reducing the on-site cabling requirements.

2 Installation
2.1 BMS8 TERMINATION BOX
All microphones use a single RJ45 (CAT5 network) connection,
which is usually terminated to a local wall mounted BMS8
Termination box.
Figure 2.1 — Typical BMS8 Termination Box
CAUTION
The BMS8 Termination Box has a standard RJ45 socket to allow
use of a standard CAT5 network cable to connect to the
microphone.
Care must be taken to ensure this socket is not used for any other
equipment since it may be damaged if connected.

2.2 CABLE IDENTIFICATION
The colour codes of the RJ45 conductors are as follows:
2.2.1 Colour Code for Processor Bypass switch
The colour code for units with a Bypass switch fitted are as shown
above, the Bypass Access using Pin 7 (Brown / White).
2.3 RECOMMENDED CABLE TYPES
The BVRD Series Microphones should be terminated to 2 x 4
core Fire Rated cable (MICC/ FP200 or similar).
It is strongly recommended that separate cables be used for the
audio pair to eliminate potential interference from the RS485
data.
Figure 2.2 — Suggested Cable Connections
* The Processor Bypass is only used on BVRD Microphones fitted
with a “Processor Bypass All Call” button.

3 Firmware Configuration
3.1 INTRODUCTION
It is necessary to configure the BVRD microphone prior to use.
This configuration includes setting system specific options such as
communication protocols, naming the inputs and outputs, DVA
message selection and setting up button allocation.
To access the USB socket on the BVRD Microphone remove the
two screws securing the Right Hand side-panel, then carefully
remove the side-panel.
Figure 3.1 — BVRD USB Socket for configuration
NOTE: The BVRD Microphone must be powered from a 24V DC supply
via the RJ45 connector before configuration is possible.

The software includes comprehensive on-line help that explains
how to correctly configure the unit to suit the installation.
Figure 3.2 — Typical Page from BVRD USB Configuration Software
3.3 LOADING “DEFAULT” VALUES
To load the default configuration settings the following procedure
should be used:
1. Remove the RJ45 lead,
2. Turn the keyswitch 45° to Emergency position,
3. Press and hold the “Speak” button,
4. Re-connect the RJ45 lead while holding the “Speak” button,
5. Unit will show a confirmation to load Factory Default

Table 3.1 — Default Factory Settings
3.4 CLEARING “LATCHED” LINE FAULTS
The BVRD Series Microphones can be configured to “Latch” line
faults. If a Line Fault is detected by the system, the microphone
can be set to keep displaying the fault even after the fault has been
cleared. This is normally used as a Fault Finding Aid.
To clear Latched faults press and hold the “FAULT ACCEPT”
button, then press and release the “AUX SELECT” button.
Release both buttons and the latched faults should be cleared.

3.5 TEMPORARY “BUZZER MUTE”
To temporarily silence the fault buzzer use the following
procedure:
1. Disconnect the RJ45 network cable.
2. Turn the “Emergency Mode” Keyswitch 45°, and press and
hold the DVA message “HOME” button.
3. Reconnect the RJ45 cable (to reconnect power).
4. Press the “HOME” button until the “OK” LED illuminates.
5. Release the “HOME” button.
3.6 FAULT FINDING: RE-SCAN PROCEDURE
If the LCD Zone Displays do not show the correct (or any) zone
information then perform the following procedure:
This forces a rescan to detect the correct number of zone buttons.
1. Turn the “Emergency Mode” Keyswitch 45°, and press and
hold the DVA message “HOME” button.
2. Press and release the “Fault Accept” button.
3. Release the “Home” button and turn off the keyswitch.
NOTE: The buzzer will remain muted until the RJ45 cable is disconnected
or power removed. While the Buzzer is muted the "OK" LED will be
permanently illuminated,
NOTE: This procedure only applies to units using Firmware V1.06 or
earlier (supplied before batch number 25192 or March 2011).
Later versions of firmware have the zone information set during
configuration.
