Description

eSENSE™ FAI II is a simple, affordable, state-of-the-art, maintenance-free CO2 concentration converter with an alarm. It is designed for installation in places where CO2 content monitoring is necessary, such as classrooms or offices.
eSENSE™ FAI II measures the CO2 concentration in the surrounding air and alerts with light and sound signals when permissible levels are exceeded.

Application

eSENSE™ FAI II is an optimal solution for climate monitoring. By measuring CO2 content, the user knows exactly when "fresh" air should be supplied to ensure acceptable indoor air quality. The operation of the ventilation system will depend on the actual need. This helps significantly reduce electricity consumption while maintaining a healthy indoor climate. eSENSE™ FAI II is suitable for both European and American standards.

The same grounding scheme must be used for the control system and the sensor.

Terminal	Purpose	Electrical Characteristics	Note Default Settings	Note Settings of this sensor
+ ~ ┴	Power (+) Power Ground (-)	24 VAC/DC + (±20%), 2W 24 VAC/DC -
Out(1) Out(2)	Analog output 1 (+)	0-10 VDC	0-2000 CO2
Green indicator				Lights up when concentration is below 800 ppm
Yellow indicator				Lights up when concentration is from 800 to 1400 ppm
Red indicator				Lights up when concentration is 1400 ppm and above
Button				When pressed, turns off the buzzer for 30 minutes. After 30 minutes, the buzzer will sound again if the CO2 concentration is above 1400 ppm
