User Interface

Can the sensor display the CO2 level to occupants? If yes describe.

Yes - Display on the sensor

User Interface

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 - Sensor display of the CO2 number turns yellow when exceeds configurable "yellow limit" (default: 700 ppm) and red when exceeds configurable "red limit" (default: 1000 ppm)

Reporting Capabilities

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 - Alerts can be generated when sensor is connected to a building automation system. Alert functionality is determined by building automation system manufacturer.

Reporting Capabilities, Integration Capabilities

How can the CO2 sensor data be logged? If proprietary software, describe (what type of account is needed, what logging intervals are available, what does it look like, and describe its capabilities including data download capabilities).

Logging data is dependent on functionality of BAS that sensor is connected to

Integration Capabilities

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.

Yes - any vendor

Integration Capabilities

If sensor can interface with a BAS or DCV system controller, is additional hardware required?

Installation

Does the sensor require specialized software for installation? If yes, describe

Installation

Does the sensor require specialized training for installation? If yes, describe

Operation

Does the sensor require on-going maintenance? If yes, describe

Operation

Does the sensor require service contracts for ongoing data access? If yes, describe

No - If sensor is connected to BAS, service contracts may be required for BAS functionality
