2 Installation
2.1 BMS8 TERMINATION B OX
The BDM 400 Microphones are designed to allow simple
installation using the minimum of system cabling.
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
C AUTION
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.

2.3 DVA M ESSAGE S ELECTION OPTION
The BDM 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 top panel of the microphones have extra cutouts behind the
overlay to allow extra switches to be fitted.
The BDM401, 404 and 408 microphones have three cutouts and
the BDM416 has seven.
It is possible to select one of a range of 8 DVA messages by closing
the relevant DVA selection point to 0V.
Please refer to the following illustration for connection details.
Figure 2.3 — DVA Message Contacts and Switch Connections
C AUTION
It is important to ensure switch terminals do not short out on the
chassis due to the limited height within the body of the
microphone.
If required, please contact our Technical Sales department for
details of suitable switches.
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.

Operating Instructions
2.4 P ROCESSOR B YPASS “A LL C ALL ” OPTION
It is possible to add an extra hard wired “All Call” processor
bypass access switch to the BDM 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 BDM401 in Parallel mode can access an "All Call" bypass
input without adding an extra switch.
NOTE: The BDM 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: If the Access line is to be monitored ensure JP4 is set to "MON".
For further information refer to Figure 2.2.

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 physical 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 Type 0 protocol to determine the correct “Channel Setting”.
Using the Type 0 protocol (compatible with BVR20 & BVR16M,
BVRD2M and CANBUS modules) the Mic Address and Channel
Setting may not be the same. This is shown in Table 3.2.
For example, if a microphone is connected to input 5 (BVRD2M)
or 9 (BVR20) then the Mic Address should be set to 5.
The Channel Setting would automatically default to 9.

The Type 1 protocol is compatible 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 physical 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 Type 2 protocol to determine the correct “Channel Setting”.
Using the Type 2 protocol (compatible with the BVRD2M and
CANBUS modules) the Mic Address and Channel Setting may not
be the same. This is shown in Table 3.4.
