VA-EOL / SL-SENSOR / BLK

Product Number: VA-EOL / SL-SENSOR / BLK


For advanced configuration such as install the VAT volume attenuators in the speaker line for volume control, the impedance of speaker line is changed after adjusting the volume on VAT volume attenuators. Furthermore, for branching the speaker line wiring, a cut of partial branching may not change the overall impedance that obviously. The VA-EOL is the only solution which can adapt the changing impedance and detect open or short circuit for each branch.

Description

VA-EOL – End of SP-Line Module for Multi-branch/3-wire

For advanced configuration such as install the VAT volume attenuators in the speaker line for volume control, the impedance of speaker line is changed after adjusting the volume on VAT volume attenuators. Furthermore, for branching the speaker line wiring, a cut of partial branching may not change the overall impedance that obviously. The VA-EOL is the only solution which can adapt the changing impedance and detect open or short circuit for each branch.


SL-SENSOR2 – 3 Wire Speaker Line Short Sensor, 2CH
SL-SENSOR4 – 3 Wire Speaker Line Short Sensor, 4CH

    

 

 

By installing the VA-EOL at the end of speaker lines and SL-SENSOR2/SL-SENSOR4 on the zone board of BTQ-VMD/SGD/SLD unit, the system can indicate whether speaker line is open or short circuit within 90 seconds (EN54-16 requirement), helping to save the analysis time. 
The installation does not require additional loopback cabling and is powered by BTQ-VMD/SGD/SLD via speaker line without affecting the audio signal. For some application like Nursery, baby may sensitive with 20 kHz monitoring tone. the speaker lines can install BLK-60/BLK-200 to filter it.

 


BLK-60 – 20kHz Signal Blocker/60W
BLK-200 – 20kHz Signal Blocker/200W


 

Features

  • Monitor the status of the loudspeaker line and all of its branches without additional loopback cabling.
  • Detect if there’s speaker line short circuits or open circuits faults by monitoring the terminated resistance value.
  • Compatible with 100V and 70V loudspeaker lines.
  • The VA-EOL is mounted inside the case of the last loudspeaker on the loudspeaker line.

– Note –
  • The supervision of speaker lines is not included the wires which are connected to the VAT volume attenuators.
  • Please order the ”EOL driver” version of BTQ unit such as BTQ-VMD/SGD/SLD controller/secondary unit when using with VA-EOL module, in order to provide more power to drive the VA-EOL module.
  • Each zone can connect to a maximum of 3 branches when using VA-EOL plus VAT volume attenuator.
