Concept of electric control centres

Standard features of all SHEVS control centres:

  • 24V- output for actuators (direction of motion is changed by reversing polarity)
  • Signal line for automatic fire detectors
  • Signal line for fire alarm button (non-automatic fire detectors)
  • Emergency power supply for at least 72 hours, automatically recharged
  • Monitoring of signal lines for wire breakage and short-circuit
  • Monitoring of accumulator, mains and fuse failure
  • Monitoring the bus line of actuators for wire breakage
  • Internal indication of status Operation / Alarm / Malfunction
  • Fire alarm button with indication status Operation / Alarm / Malfunction and Reset button connectable
  • Possibility of connecting a Fire Alarm Control Panel (BMZ) for triggering of alarm
  • Possibility of connecting a Wind and Rain Control System (WRS)
  • Reverse-connect and deep-discharging protection of the accumulators
  • Cycle repetition for reliable opening in the case of SHE action
  • Selectable function: closes automatically when alarm has been reset (auto closing)
  • Selectable function: malfunction of a signal line will trigger alarm (Malfunction = Alarm)
  • Adjustable maximum ventilation position (stroke limitation) 
  • Manual ventilation in “Start-Stop” mode (buttons are pressed briefly only, need not to be held) or in “dead man’s mode” (longer buttonpress, after releasing the actuators stop)
  • Accumulators with VdS approval
