Speaker line monitor module
The surveillance monitor VX-300SM-EB can easily be installed in a cabinet rack on standard DIN rails. It controls up to 8 EOL modules, each connected to one speaker line. The monitor informs single speaker line faults (short circuit or break) by individual control outputs as well as a general speaker line fault by a separate control output. Green LEDs on the module corresponding with the loudspeaker lines indicate the correct function of each.
The 3-wire EOL-system is certified together with the VX-3000 system.

3-Wire end-of-line (EOL) monitor module for 8 end-of-line modules for substituting 5-wire end-of-line modules. The EOL monitor shall be connected to up to 8 speaker lines and provide a failure output per speaker line and a general speaker line failure output by an open-collector transistor. A green LED per speaker line shall light when the speaker line is working correctly.
The 3-wire EOL monitor shall operate with DC voltage of 19 up to 33 volts and consume maximal 100 mA current. It shall be on a circuit board with clamps for DIN-rail mounting. The connector for the speaker lines, supply voltage and general failure output shall be a screw terminal. The connector for the single speaker line failure outputs shall be a shieldes RJ45 jack.
