Applications

Fault signaling in ventilation and smoke extraction systems.
Filter clogging signal.
Fault signaling in gas VMC installations: COPREC requires the use of a fan equipped by the manufacturer with a pressure switch fitted and adjusted in the factory.

Selection

Filter clogging signal:

Select the BDEZ whose operating range corresponds to the maximum pressure of the clogged filter.
- Example - max pressure of the dirty filter: 400Pa, select a BDEZ 100-1000Pa and set it to 400Pa.

Fault signaling in ventilation and smoke extraction systems:

The BDEZ accepts a continuous overpressure of +/-5000Pa without degradation of the component or alteration of the precision.
For this application, the BDEZ can be used outside its operating range.
- Example - network pressure: 500Pa, using a BDEZ 20-300Pa set to 300Pa.
  In the event of a fault in the ventilation system, the pressure will drop and the pressure switch will signal the fault as soon as the 300Pa threshold is crossed.
