K+G Control Unit RWZ
K+G Control Unit RWZ
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
