Control panels for Pressure Differential Systems (PDS). Designed and programmed to satisfy the requirements described in EN 12101-6. These allow automatic control of airflow and pressure differential in escape routes, elevators or shelter areas. Series for systems that also require control of a fail-safe motorized damper with integrated optical smoke detector.
System Control – Fire fighters key-lock switch
AUTO: Automatic control through pressure transducer + VSD (default position).
ON: Manual activation of the system with 2 pre-set fan speeds (MIN/MAX). Allows to manually force the MD dampers to open, ignoring the smoke sensor.
OFF: Manual STOP and system reset, ignores external signals.
