Base Loop Sounder VEGA

32 Tones Base Loop Sounder VEGA, Built-in bidirectional isolator VBLS100 Argus Security

VBLS100-32 - 32 Tones Base Loop Sounder VEGA

The VBLS100 is a Vega series high efficiency electronic addressable multi-tone platform base sounder. Device's supply power is drawn from the analogue detection loop.
The Vega communication protocol enables the monitoring control panel to identify the VBLS100 as a sounder type and initiate actions accordingly.
The control panel is also capable to select an appropriate tone pattern (e.g. for pre-alarm or evacuate conditions) and groups of VBLS100 sounders can be synchronised (those features require the implementation by the control panel manufacturer).
All Vega analogue series devices are equipped with integrated short circuit isolators which monitor the analogue loop and can be activated by the control panel.

- Built-in bidirectional isolator
- Large capacity, up to 240 devices per loop
- Auto addressing capability (control panel feature) or manually via VPU100 programmer
- High power availability from loop (>98%)
- Digital checking of double address
