User interface
1. Can the sensor display the CO2 level to occupants? If yes describe.
Yes - Sensor displays live CO2 readings and graph of historical CO2 data on LCD screen. Display also available through webpage.
User interface
2. Can the sensor display a visual indicator to occupants that the CO2 level has exceeded a programmed threshold? If yes, describe (what does the indicator look like, what the default thresholds are, and can the threshold be changed).
Yes - Built-in green LED lights up when CO2 is below the low setpoint (800 ppm by default), built-in red LED lights up when CO2 is above the high setpoint (1200 ppm by default), and built-in yellow LED lights up when CO2 is between the low and high setpoints. Limits are programmable on the device.
Reporting capabilities
3. Can the sensor alert facilities (such as an email, text, or call phone application) when the CO2 level has exceeded a programmed threshold? If yes, describe (what does the indicator look like and can the threshold be changed).
Yes - Sensor has an auditory alarm that sounds when CO2 exceeds the high setpoint. The alarm can be muted.
Integration capabilities
4. Can the CO2 sensor interface with a building automation system (BAS) or demand control ventilation (DCV) system controller? If yes, describe if integration capabilities are vendor specific.
No
Integration capabilities
5. If sensor can interface with a BAS or DCV system controller, is additional hardware required?
NA
