GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM ROOM CARBON DIOXIDE DETECTOR CD2RMC SERIES PRODUCT DESCRIPTION The room CO2 transmitter device uses a highly accurate and reliable nondispersive infrared (NDIR) sensor in an attractive, low profile enclosure for room applications to monitor CO2 levels. The sensor uses dual wavelength optics and LTA (long term adjustment) signal processing technology to deliver industry leading long-term accuracy and reliability. These technology features ensure optimum measurement stability for both periodic and constant occupancy applications, so the device is equally suitable for a classroom or a hospital room. Standard features include a field selectable output signal of either 4-20 mA, 0-5 Vdc or 0-10 Vdc for the highest versatility, programmable CO2 measurement span, a backlit alpha-numeric LCD and easy menu operation for configuration. Optional features include a resistive temperature sensor output (with LCD display of temperature in either °C or °F), 2 button setpoint adjustment, a control relay with programmable setpoint, hysteresis and time delay, and a dry-contact override switch. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The CD2RMC series can be mounted directly to a single gang electrical box or directly to a wall. The backplate includes many mounting hole configurations to allow for mounting on a variety of electrical boxes. The basic CD2RMC has a 3 wire configuration with a screw block terminal provided for connection to the Building Automation System.

This feature is recommended for applications where the CO2 level will be close to normal (400 ppm) at least one hour per day. If the monitored space is occupied 24 hours or consistently maintains higher or lower levels of CO2, it is recommended that this feature be turned off, but yearly calibration will be required. 58 mm 2.3" 82.6 mm 3.25" 29 mm 1.15" 119 mm 4.7" 84 mm 3.3"

If the sensor is found to be out of calibration more than 150 PPM as compared to a calibration gas or recently calibrated reference, Greystone will provide a free factory calibration of the sensor if returned to Greystone. This guarantee only applies if the sensor is operated in an environment where inside levels periodically drop to outside concentrations (i.e. during evenings or weekends when there is no occupancy) as is required by ASC software.
