Description

This 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 refrigerants where high-efficiency, high volume refrigerant 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 profile, aesthetically pleasing enclosure is designed to reduce the noticeability of the device by the public eye.

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 firmware and configuration can be upgraded in the field using the USB connection.

The digital models are user configurable in the field for BACnet® MS-TP RS-485 or Modbus® RTU RS-485 output for communicating with a controller, Building Automation System or other control panel.

Both the analog and digital models may be configured with an internal gas sensor or a remote refrigerant sensor (dongle). The internal sensor model is ideal for vertical terminal air conditioner (VTAC) systems. The remote refrigerant sensor model has a 9m / 29.5ft dongle cable that is ideal for use in packaged terminal air conditioner (PTAC) applications.
