12.3.3 EOL supervision board

The procedure for installing an EOL supervision board is similar to the installation of a loudspeaker supervision board (see section 12.3.2). However, the EOL supervision board does not contain faston connectors (see figure 12.7).

Note

The board must be connected after the ceramic terminal block with the thermal fuse. In case of a fire, the thermal fuse will act and disconnect the board from the loudspeaker line. The trip point of the thermal fuse that is connected to the ceramic block is lower than the melting point of the solder on the board to prevent short-circuits in the supervision board and the loudspeaker line.

Note

When the loudspeaker does not contain a ceramic block with a thermal fuse, use an LBC1256/00 EVAC Connection Adapter (see chapter 14).

12.4Addressing

All LBB4441/00 Loudspeaker Supervision Boards and LBB4443/00 EOL Supervision Boards must have an address for communication purposes. All LBB4441/00 Loudspeaker Supervision Boards and LBB4443/00 EOL Supervision Boards that are connected to the same amplifier channel must have a different address. Use the S700 and S701 switches to assign a (hexadecimal) address in the range of 00 to 4F to the board. The S700 switch sets the right digit, whereas the S701 switch sets the left digit of the address. Each switch has 16 hexadecimal positions (0 to F).
