The Series CDTA Communicating Carbon Dioxide Detector combines the function of three room sensors
into a single, compact housing. Parameters include carbon dioxide, humidity, temperature, and
temperature set point with override. By having field selectable Modbus® and BACnet Communications,
only four wires are needed for power and the communication signal. The communicating detectors can be
daisy-chained together to further reduce installation cost. In order to reduce the set up time, the RS-485
MAC address is set up using on board dip switches. A second set of dip switches are used to select
whether output is Modbus® RTU or BACnet MS/TP communication protocols and to limit access to the set
up menu.
