Header not included. Signal Update Every 5 seconds Warm Up Time Notes: (1) Tolerance based on span gas of ±2%, which adds to the uncertainty, tested at Standard Ambient Temperature and Pressure (SATP). (2) Subjecting sensors to environments less than 400 ppm for more than 15 minutes may affect accuracy due to ABC Logic algorithm. (3) Please call for detailed product (4) Based on nominal 5VDC input voltage. For best performance, DC supply should be a regulated, low noise power source. • < 2 minutes (operational) • 10 minutes (maximum accuracy) Operating Conditions • 14°F to 140°F (-10°C to 60°C) • 0 to 95% RH, non-condensing Storage Conditions -22°F to 158°F (-30°C to 70°C) Page 2 of 3 Willow Technologies Ltd.

Full accuracy to be achieved utilizing ABC Logic. With ABC Logic enabled, the sensor will typically reach its operational accuracy after 24 hours of continuous operation. Sensor will maintain accuracy specifications with ABC Logic enabled, given that it is at least four times in 21 days exposed to a reference level of 400 ppm. Note: Applies when used in typical residential ambient air. Consult Telaire if other gases or corrosive agents are part of the application environment.

Precautions should be taken to observe limits and prevent damage from electrostatic discharge or rough handling. Please refer to ANSI/ESD S20. 20-1999 for more information on preventing ESD damage and IPC 610 Rev D for more information on proper electronic assembly practices. Available Models Part Number Sampling Method T6713 Diffusion Measurement Range 0-2000 ppm T6713-5k Diffusion 0-5000 ppm Safety Before installing, handling, using, or servicing this product, please consult the data sheet and application notes. The product shall be used only within power supply and electrical input and output limits as by the datasheet and application guide. Improper use of the product may result in product damage and property loss and/or personal injury. In use of the product, the customer has sole responsibility for designing and implementing a solution which will ensure safe operation (including review of appropriate reliability or required redundancy, mitigation of failure modes, and/or meeting appropriate standards). The customer is responsible for review of any special conditions for use including, but not limited to, environmental conditions, electrical supply, residual risk, etc). The sensor is designed for benign environments. The performance and reliability may be negatively affected in environments that contain corrosive or caustic gases including but not limited to Ammonia, Chlorine, NOx and Ozone. Telaire makes no warranty, representation or guarantee regarding the suitability of this product for any particular application, including safety critical applications. Nor does Telaire assume any liability arising out of the application or use in any product or circuit. disclaims all liability without Telaire limitation consequential or incidental damages. No statuary or for particular purpose shall be implied. Calibration Telaire does not recommend the customer recalibrate the T6713 module after installation. The sensor ABC Logic algorithm will begin after 24 hours, adjusting the sensor measurement resulting in sensor-to-sensor consistency. If immediate consistency is desired, the sensors may be single point calibrated using pre-mixed reference gas or ambient air measured by a reference sensor.
