End of Line Monitoring
The VX-200SP-2 is an audio signal output module of the VX-2000 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 line unit to the end of the speaker line eliminates the necessity of using the speaker line for line monitoring. However, the shielded cable can be used as the third wire.
Supplied from VX-2000SF
Transfer type, withstand voltage: 30 V DC, 250 V AC, contact current: under 7 A
Steel plate, surface-treated
30.5 x 132.6 x 290.3 mm (W x H x D)

Loudspeaker circuit amplifier monitoring module, uninterrupted permanent monitoring short-circuit and interruption via Linienendmodul. Monitoring is carried out also during the transmission of background music and announcements of any kind and does not interrupt them. The amplifier monitoring is also without any interruption. Fault detection for 100 seconds. Switch off the speaker circuit for short circuit. Optional 9-band graphic equalizer can be retrofitted.
