The FCP-OT320-R470 Multisensor Detectors each combine two detection principles. All sensor
signals are analyzed continually by the internal evaluation electronics and are linked with each other.
If a signal combination fits the detector's programmed code field, an alarm is automatically triggered. By linking the sensors, the combined detectors can also be used in places where work carried out gives rise to light smoke, steam or dust.
The enhanced operating voltage range of 8,5 V DC up to 30 V DC and 470 Ω alarm resistor.
