The 3-Wire EOL-System, consisting of the surveillance monitor VX-300SM-EB and the EOL module VX-300SV-EB, reduces the number of wires used for the loudspeaker lines by two compared with the EOL module VM-300SV. This lowers cable cost as well as cost for installation material (terminals etc.).
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 EOL module VX-300SV-EB comes in an IP65 rated box with a cable gland. Internally it provides a thermal fuse and a ceramic terminal to prevent the speaker line from a short circuit in case of fire. The terminal provides connecting the speaker line and the control wire.
The 3-wire EOL-system is certified together with the VX-3000 system.
