The FSC-UFC24 has the option to work without the bus communication connected. There is one input to
open or close the damper, depending on the fire or smoke extraction application. It is also possible to
monitor the damper position conventionally through a digital output signal.
The analog output, signals the status of the FSC-UFC24:
• 0V – No Power to FSC-UFC24
• 2V – Damper Open
• 4V – Damper Close
• 6V – Smoke Detector Alarm
• 8V – Thermoel. Tripping Device Alarm
• 10V – More than one Alarm Condition
During normal operation this output will signalize the position of the damper (2V, 4V).
This output can be connected in parallel between the various FSC-UFC24 in order to monitor their status.
Current output max is 5mA.
Digital input volt free, normally open as default (can be changed on bus).
The digital input allows to control the damper position through an external contact/device.
Selection of the analog settings by dip switch.
This digital input for the analog application in the FSC-UFC24 overrides always the bus commands.
