Automation Components, Inc.GAS | CO2 ROOMGAS | ## Call: 1-888-967-5224 | Web: www.workaci.com C02 ROOMSensor with Temperature, Setpoint & OverrideThe ACI Carbon Dioxide Room Series (A/CO2-R2) monitors the carbon dioxide (CO2) levels in commercial, school, and oce-type environments. The concentration of CO2 is a strong indication of the overall indoor air quality. The A/CO2 Series is based on a single beam, non-dispersive infrared technology and is a cost-ecient solution for measuring carbon dioxide levels for building climate control. In addition, ABC software eliminates the need for manual calibration. Carbon Dioxide concentration is measured up to 2,000 ppm and is converted into proportional analog outputs. The factory default output is 4-20 mA, whereas 0-5 VDC and 0-10 VDC outputs are eld selectable via integral dip switches. Thermistor temperature outputs, along with setpoint and override, are available as options for this conguration as well. Please see the order grid for the available sensor options. The A/CO2-R2 Series provides data which can be used in conjunction with a Building Automation System or Demand Control Ventilation to decrease energy consumption while creating a healthier indoor climate.Applications: Schools, Oce Buildings, Auditoriums, Gymnasiums, Shopping Malls, Theatres, Demand Control Ventilation & EconomizersThe CO2 Room Series are covered by ACI's Five (5) Year Limited Warranty. The warranty can be found in the front of ACI's Sensors & Transmitters catalog, as well as on ACI's website, www.workaci.com.PRODUCT SPECIFICATIONSSupply Voltage:Power Consumption:Sensing Technology:Sensing Method:Measurement Range Default:Extended CO2 Ranges:Extended Range Accuracy:CO2 Output Signal:Fail Safe:CO2 Accuracy :Pressure Dependence:Response Time:Warm-Up Time:Temperature Output Range:Temperature Accuracy:Operating Temperature Range:Operating Humidity Range:Enclosure:Sensor Coverage Area:Mounting Height:Sensor Life :Calibration Product Dimensions:Product Weight:Agency Approvals:24 VAC +/-20%, 50/60 Hz (half-wave rectier) | 16.5-40 VDC Max.3 VA for 24 VAC, 3W for 24 VDC (peak); <0.9W (average)Single beam infrared sensing technology (NDIR)Diusion0 to 2,000 ppm Up to 10,000 ppm (factory set)+/- 30 ppm and +/- 5% of readingOutput 1: 0-5 VDC or 0-10 VDC (Default) | Output 2: 4-20 mA (500 Ohm Load maximum)Polarity protected+/- 40 ppm +/- 3% of reading (@ 15-35°C; 20-70% RH and 101.3 kPa)+ 1.6% reading per kPa (deviation from standard pressure 101.3 kPa)≤ 2 minutes, diusion < 1 minute (@ full specs < 15 minutes)Various (see ordering grid)+/- 1°F (+/- 0.6ºC)32 to 122ºF (0 to 50ºC)0 to 95%, non-condensingABS, Plastic, White, UL94-HB7,500 sq. ft maximum4-6 ft> 15 years (typical)ABC algorithm (Automatic Baseline Correction)(H) 4.50” (114.30 mm) x (W) 2.75” (69.85 mm) x (D) 1.12” (28.45 mm)0.230 lbs (0.104 kg)EMC Directive 2014/30/EC | RoHS Directive 2011/65/EUNote : Accuracy is dered after minimum three (3) ABC periods (1 period = 8 days) of continous operations | Note : In normal indoor air quality (IAQ) applications | Corrosive environments are excluded | Note : Building CO2 levels must drop to 400 ppm same time during the week for ABC to work properly | If the building is occupied 24 hours / day, ABC must be turned oDC = Dry Contact (Separate Input)Automation Components, Inc.GAS | CO2 ROOMDIMENSIONAL DRAWINGGAS | ## Call: 1-888-967-5224 | Web: www.workaci.com 1.12”(28.45mm)4.50”(114.30mm)4.50”(114.30mm)2.75” (69.85mm)Front ViewRight ViewBottom ViewSTANDARD ORDERINGModel #A/CO2-R2CO2_CONFIGURATORItem #144220CO2CONFIGDescriptionCO2 Room (0-5 VDC, 0-10 VDC, 4-20 mA Outputs)CO2 Room Congurator for Temperature, Setpoint & Override (0-5 VDC, 0-10 VDC, 4-20 mA Outputs)-OR-Model # Example:CO2_CONFIGURATORCO2CONFIG---- (None) | 400 Ohms | 1K Ohms | 2K Ohms | 5K Ohms | 8.5K Ohms | 10K Ohms20K Ohms | 100K Ohms A/CO2-R2A.
