TOA VX-200SP-2 pilot tone detection module
TOA VX-200SP-2 is an audio signal output module of the VX-2000 voice evacuation system with speaker line pilot tone detection. This module is to be mounted in the VX-2000SF surveillance frame and detects speaker line short circuits, open circuits by monitoring the terminated resistance value of the end of line unit, and ground fault. Connecting the supplied end of line unit to the end of the speaker line eliminates the necessity of using the speaker line for line monitoring. However, the shielded cable must be used for speaker line.
