Control panels for Pressure Differential Systems (PDS)
PDS CONTROL MD

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.

Main Features
Performance verified in AMCA accredited and ENAC audited laboratory.
Key-lock switch for manual override for fire-fighters (ON/AUTO/OFF), also useful for commissioning stage and maintenance operations.
AUTO/OPEN for damper control, forces its opening ignoring the smoke sensor.
Remote control using PDS REM MD series accessories.
Status indicators: PDS CONTROL OK/FAN ON/FAULT/FIRE/DAMPER OPEN/SMOKE IN DAMPER.
Calibration-friendly for ease of commissioning and routine maintenance operations.
Pre-cabled maneuver for remote activation of daily ventilation, by means of a time programmer.
Outputs for status monitoring.
Modbus protocol communication available.

Modbus notes
