TECHNICAL DRAWING The cGas Detector Carbon Dioxide Transmitter is a low maintenance gas monitoring device designed for use in non-explosion rated, commercial

applications that require continuous monitoring of CO 2.

It o# ers one 4-20 mA analog output or a user selectable in the ! eld digital output with your choice of BACnet® or Modbus® for communicat- ing with a System or ventilation controller. Ideal for use for applications where compressed CO2 is used and stored, climate control in commercial buildings and other processes requiring the

continuous monitoring of CO 2.

Powered by 24 VDC or ground referenced AC, the CO 2 cGas Detector has an LCD display, temperature compensation and the ! rmware and con! guration can be upgraded in the ! eld using the USB connection. Pre-calibrated sensors with true Plug & Play Smart Sensor technology TECHNICAL SPECIFICATIONS makes replacing sensors quick and easy. GAS TYPE Carbon dioxide (CO ) The cGas CO2 Detector comes in a standard water / dust tight, corrosion 2 resistant ABS/ polycarbonate enclosure with a hinged, secured door. With the optional, factory installed splash guard the enclosure is IP54 rated and MECHANICAL provides protection in water spray or wash down applications.

TECHNICAL DRAWING

The cGas Detector is designed for use in publicly occupied spaces where integrated demand controlled ventilation (DCV) is used for air quality and energy savings; for continuous monitoring of where high-e# ciency, high volume cooling and heating systems (VRF) are used to keep the indoor environment comfortable; and for other continuous monitoring of hazardous gases in publicly frequented areas. The low pro! le, aesthetically pleasing enclosure is designed to reduce the noticeability of the device by the public eye. It is secured by a mounting plate that can be mounted proud of the wall or $ ush with the wall using a junction box.

Both the analog and digital models are powered by 24 VDC or ground referenced AC, come with an LCD display, temperature compensation and thermal resetting fuse. Sensor replacement is easy with true Plug & Play smart sensors that arrive pre-calibrated. The ! rmware and con! guration TECHNICAL SPECIFICATIONS can be upgraded in the ! eld using the USB connection. MECHANICAL White ABS / Polycarbonate, low pro! le with The digital models are user con! gurable in the ! eld for BACnet® MS-TP Enclosure RS-485 or Modbus® RTU RS-485 output for communicating with a mounting plate controller, Building Automation System or other control panel.
