EX8000™ Multi Zone Control Unit

The EX8000™ Multi Zone Control Unit is responsible for the protection system control and status verification functions. The electronic system is integrated on a modern and reliable board with redundant circuitry for all safety functions. Power supply, emergency
battery and connection technology are all accommodated within the cabinet.
All signals from the explosion pressure, spark, flame or temperature sensors employed in the protection system are recorded, tested and evaluated by the EX8000. The monitoring and activation circuits are continuously checked with regard to wire breakage, earth fault and short circuit. In addition, an automatic self-test system ensures that all safety relevant functions of the EX8000 are monitored. In case of power failure the emergency battery automatically takes over without interruption and can be sustained from 4 hours to 24 hours, depending on the application requirement.
All fault and alarm messages are displayed by both light emitting diodes (LED) and the EX8000 front panel display which can also be forwarded by means of potential-free contacts.
The EX8000 offers maximum flexibility to users of multi actuation zone applications through its modular approach. Depending on the configuration of the explosion protection system the related protection measures are activated selectively. The
EX8000 base unit allows control and indication of four detection and activation circuits (zones). This can be scaled-up depending on the needs of the application, up to 16 zones within one standard wall mount unit. The floor mounted cabinet version can handle even up to 32 zones. These features make the EX8000 the most comprehensive solution on the market.
