BDM 400 Microphones Operating Instructions S AFETY I NFORMATION Personnel who install, maintain or repair this equipment must read the safety information below before starting work. Voltages in excess of 30 Volts RMS or 50 Volts DC are considered Hazardous and in certain circumstances can be lethal.
BDM 400 Microphones Operating Instructions 1 Introduction The BDM 400 range of intelligent Microphones are designed to provide a wide variety of features to suit any installation. Figure 1.1 — Typical BDM416 Microphone The Microphones communicate with the main control system via an RS485 communications link, and as the only connection required on each unit is made using a standard RJ45 Network cable connection (carrying both Audio and Serial Data) system wiring is considerably reduced.

BDM 400 Microphones Operating Instructions 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.
BDM 400 Microphones Operating Instructions 2.2 H ARDWARE S WITCHES AND S ETTINGS Depending on model, there are up to 6 settings that are available by removing the right hand side panel of the microphone. These are shown in Figure 2.2. Figure 2.2 — Hardware Settings (BDM401 shown) Ident Marked As...
BDM 400 Microphones Operating Instructions 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.
BDM 400 Microphones 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.

BDM 400 Microphones Operating Instructions 2.6 WALL M OUNTING O PTION (BDM3WB) The Wall Mounting option (product code BDM3WB) allows any of the BDM 400 Microphones to be wall mounted. The BDM3WB is separate back plate that is secured to the wall. The overall dimensions and the positions of the mounting holes of the back plate are shown in Figure 2.5 Figure 2.5 — Mounting hole positions on BDM3WB 2.6.1 Installation Instructions 1. Mount the back plate on the wall. 2.

BDM 400 Microphones Operating Instructions 3 Firmware Configuration It is necessary to configure the microphone prior to use. This configuration includes setting system specific options such 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 L OADING “D EFAULT ” VALUES To load the default settings (shown in Table 3.1) the following procedure should be used: 1. Remove the RJ45 lead, 2.
