AirSense Stratos Remote Display Unit (RDU)

The AirSense Remote Display Unit (RDU) is an LED bar graph repeater and status display used to remotely mimic the status of a Stratos ASD. It comes in a 19” rack format, that allows for multiple units to be mounted next to one other in a 19" rack, or individually, with the support of the 9-30817 housing.  The RDU is connected to the SenseNET bus which provides the dataflow between the unit and the ASD. A bank of switches selects the detector with the display to be repeated. The unit is powered from a 24V DC nominal power supply.  The RDU provides, by way of LEDs basic, OK and faults indication, 4 alarm levels, and a bar graph display which shows the level of obscuration. The RDU can also be expanded with a relay card (9-30803) which provides relay output for the 4 alarm flags and fault indication.
