ZENiX 1SDST - Field device for monitoring and controlling 1 motorized smoke control damper with ST-connection plugs

The ZENiX 1SDST field device is used to monitor and control 1 motorized smoke control damper with 24 V actuator with ST-connection plugs. No configuration is required as it has a predefined device address.


  • Suited for a 24 V smoke control actuator with ST-plug, such as a BLE24ST, BE24ST, BEN24ST, BEE24ST...
  • Predefined address: no need for addressing or configuration of the field device
  • Functional also without 230 V power on the field device: it will send the current damper position, but will not be able to move the damper blade without power
  • Actuator isolated from mains by a transformer
  • LEDs indicate position of the damper, bus communication and error status


  • Connection to one 24 V smoke damper actuator with ST-plug
  • Nominal voltage: 230 V AC
  • Power consumption: 300 mW + actuator consumption
  • For wire sizing: 18 VA
  • IP54 casing
  • CE according to 2004/108/EC and 2006/95/C
