Model Info

TOA VX-200SZ-2 is an audio signal output module of the VX-2000 voice evacuation system with speaker line impedance detection. This module is to be mounted in the VX-2000SF surveillance frame and detects speaker line short circuits, open circuits by comparing impedance readings, and ground fault. Since the module is equipped with 2 speaker outputs (A and B), broadcasts can be maintained even if one of the two outputs fails. Failures are indicated by the LED on the panel.
