Control sequence and power
The VRS 10 provides the rain signal; the control panel and programmed sequence determine the closing response. Where an opening must close during a mains failure, the selected control architecture must retain enough operating power to drive it closed. In combined smoke and natural ventilation systems, the approved fire-mode priority remains authoritative.
