2 Installation
2.1 MOUNTING THE ENCLOSURE
To gain access to the mounting holes, open the box and remove
the 4 off M5x8mm screws securing the inner panel. Carefully
remove the panel and detach the CAT5 cable from the
termination PCB.
Store the inner panel safely until it can be r
efitted.

2.2 HARDWARE SWITCHES AND SETTINGS
There are 8 settings that are only available when the inner panel is
removed. These are shown in Figure 2.2 (the PCB has been
detached from the panel for clarity).

E O/P Level Sets the Output level
F IND Level Sets the Indicator sensitivity (factory preset)
G A-DC Enables audio output DC monitoring, set to MON to enable
m
onitoring. This option must also be enabled in configuration
H LK3 Make link if a "Bypass" switch is fitted
I LK2 Make link to connect "BYPASS" output to +V IN.
Can only be used if Bypass switch is not fitted.
NOTE: Monitoring of the Access Line is only applicable to the BFM401
when it is set to "Parallel" Mode or multi-zone BFM microphones with a
Bypass "All Call" switch fitted. Monitoring is acheived by placing a
Zener Diode between the Access Line and 0V.
NOTE: * The Factory Default setting for BFM401 is "S" position for
"Serial" operation.

2.3 DVA MESSAGE SELECTION OPTION
The BFM 400 Microphones include an option to broadcast DVA
Messages to either selected or all zones.
NOTE: This is a modification that is normally a factory fitted option.
The front panel of the microphones have extra cutouts behind the
overlay to allow extra switches to be fitted.
It is possible to select one of a range of 7 DVA messages by closing
the r
elevant DVA selection point to 0V.
Please refer to the following illustra
tion for connection details.
Figure 2.3 — DVA Message Contacts and Switch Connections
NOTE: If using Type 0 RS485 protocol it is only possible to select DVA
Messages 1-7.
With Type 1, 2 or 3 RS485 protocol the range of the DVA messages can
be set during configuration. Refer to Section 3.4 for details.

2.4 PROCESSOR BYPASS “ALL CALL” OPTION
It is possible to add an extra hard wired “All Call” processor
bypass access switch to the BFM microphones to enable
broadcasts in the unlikely event that the router suffers from a
processor fault or RS485 network failure.
NOTE: This is a modification that is normally a factory fitted option.
NOTE: The BFM01 can be configured to work in Parallel mode to access
an "All Call" bypass input without adding an extra switch.
NOTE: The BFM microphone must be connected to the correct input on
the BVRD2M for the processor bypass to operate.
The bypass switch should be connected between JP8 & JP9, a
solder bridge should be made across LK3, and LK4 should be
carefully drilled out as shown in Figure 2.4.
Figure 2.4 — Connections required for Processor Bypass “All Call” switch
NOTE: The Access Level must be set via JP4 to either 3V3 or 10V which
must match the Access Level for the Bypass or CI Input that it is connected
to. For further information refer to Figure 2.2.

2.5 ELECTRICAL CONNECTIONS
All electrical connections to the microphone are made using the
connector block mounted on the termination PCB.
To avoid the possibility of interfer
ence between the Audio and
Data we recommend each microphone is connected using two
separate 4 core Fire Rated cables, one carrying the Audio pair and
the other the Serial Data pair.
Figure 2.5 — Termination PCB
NOTE: The Termination details shown on the PCB are for Serial
Connection using RS485 data.
Refer to the table below for Parallel Connection details.
The BFM Factory Default setting is "Serial".
Legend Serial Connections Parallel Connections

3 Firmware Configuration
It is necessary to configure the microphone prior to use.
This configuration includes setting system specific options suc
h as
enabling the unit to communicate with the system, enabling
monitoring of the microphone capsule, and setting the delay
before the “Speak Now” indicator illuminates.
3.1 LOADING “DEFAULT” VALUES
To load the default settings (shown in Table 3.1 ) the following
procedure should be used:
1. Remove the RJ45 lead,
2. Press and hold the “Speak” button,
3. Re-connect the RJ45 lead,
4. Release the “Speak” button after 3 seconds.
Default configuration values will then be loaded into the unit.
Note: Before the Microphone can be used the RS485 button allocation
data must be downloaded from the BVRD2M.
Press and hold the "FAULT ACCEPT" button for 2 seconds to load the
current button allocation data.
It is necessary to download this data after entering Configuration Mode.
Note: If loading of Default values has changed any of the set values it
will be neccasary to press and hold the "Faul Accept" and "Speak"
buttons for 5 seconds in order to accept the new Configuration. Failure to
perform this step will result in the Microphone and connected BVRD2M/
4 routers indicating a Fault.

NOTE: If the Protocol is changed then the Mic Address MUST
BE RE-ENTERED or the Channel Setting may be incorrect.
3.5 MODIFYING CONFIGURATION SETTINGS
1. Enter the Configuration Mode as described in Section 3.3.
2. Press the “Fault Accept” button to step thr
ough to the
required location within the Configuration Table.
3. The “Busy” LED flashes to indica
te the location within the
table and the “Speak Now” LED flashes to indicate the
current setting.
4. To modify the value of the cur
rent setting press the “Speak”
button the required number of times e.g. if the 3rd value is
required press the “Speak” button three times.
The Buzzer will then sound and the “F
ault” LED will
illuminate for one second to show the value has been
accepted.
After a short delay the “Speak Now” LED will flash the
r
evised number of times.
5. To move to the next position within the configura
tion table
press the “Fault Accept” button.
6. To exit from Configuration Mode disconnect the RJ45 cab
le.
7. When the RJ45 cable is reconnected the micr
ophone will use
the new configuration details.
8. After a configuration change has been made the new
configura
tion must be accepted by pressing and holding the
"Fault Accept" and "Speak" buttons for 5 seconds. Failure to
perform this step will force the Microphone to indicate a
fault, the connected BVRD2M or BVRD2M4 router to

indicate a "Transmission Fault" and after 1 hour the
connected BVRD2M or BVRD2M4 will indicate a "System
Fault" which will need to be manually accepted and reset at
the router.
Note: Before the Microphone can be used the RS485 button allocation
data must be downloaded from the BVRD2M.
Press and hold the "FAULT ACCEPT" button for 2 seconds to load the
current button allocation data.
It is necessary to download this data after entering Configuration Mode.
NOTE: If the Protocol is changed then the Mic Address MUST
BE RE-ENTERED or the Channel Setting may be incorrect.
NOTE: If a configuration change is made it must be accepted
by following step 8 above.

3.6 MIC ADDRESS & CHANNEL SETTINGS
3.6.1 Setting Mic Address (using Type 0 protocol)
The unit must be set to the correct Mic Address to allow
monitoring of communications between the mic and the router,
and also to identify the mic if the “Listen In” function is selected.
To set the Mic Address, determine the ph
ysical input that the
microphone is to be connected to, and enter the corresponding
value shown in Table 3. 2.
The firmware within the microphone uses the Mic Address and
the T
ype 0 protocol to determine the correct “Channel Setting”.
Using the Type 0 protocol (compatible with BVR20 & BVR16M,
BVRD2M and CANBUS modules) the Mic Addr
ess and Channel
Setting may not be the same. This is shown in Tabl e 3. 2.
For example, if a microphone is connected to input 5 (BVRD2M)
or 9 (BVR20) then the Mic Addr
ess should be set to 5.
The Channel Setting would automa
tically default to 9.

3.6.2 Setting Mic Address (using Type 1 protocol)
The unit must be set to the correct Mic Address to allow
monitoring of communications between the mic and the router,
and also to identify the mic if the “Listen In” function is selected.
To set the Mic Address, deter
mine the physical input that the
microphone is to be connected to, and enter the corresponding
value shown in Tab le 3 .3.
The firmware within the microphone uses the Mic Addr
ess and
the Type 1 protocol to determine the correct “Channel Setting”.
The Type 1 protocol is compa
tible with BVR20 & BVR16M,
BVRD2M and CANBUS modules.

3.6.3 Setting Mic Address (Type 2 & 3 protocol)
The unit must be set to the correct Mic Address to allow
monitoring of communications between the mic and the router,
and also to identify the mic if the “Listen In” function is selected.
To set the Mic Address, determine the ph
ysical input that the
microphone is to be connected to, and enter the corresponding
value shown in Table 3. 4.
The firmware within the microphone uses the Mic Address and
the T
ype 2 protocol to determine the correct “Channel Setting”.
Using the Type 2 protocol (compa
