LCN-Air quality

Air quality sensor as a ready set for installation – available in January 2021

Especially in the current time it is important to ventilate assembly rooms regularly and professionally. This is what the LCN-GSA4 is for. The LCN-GSA4 is a precise air quality measuring device with built-in AI.
It displays the air quality with a bargraph, prompts for ventilation with a red ring of light and warns with beeps in case of further deterioration.
The thresholds for the warnings are programmable and factory set to approximately 2500 ppm / 3000 ppm.

How it works

The LCN-GSA4 measures the quality of the room air and uses this to determine the CO2 content of the air.
Both values, air quality and CO2, are made available in variables.
These values can be used, for example, to control the bargraph of the LCN-GSA4 or to activate its alarm buzzer via threshold values.
Furthermore, up to 4 keys can be used to trigger actions in the LCN bus.
The LCN-GSA4 is a precise measuring device for air quality and is ideally suited for regular and professional ventilation.
It displays the air quality with a bar graph, prompts for ventilation with a red light ring and warns with beeps in case of further deterioration.
The thresholds for the warnings are programmable.

Areas of application:

  • Measurement sensor for wall mounting in a 68mm flush-mounted box
  • Elegant appearance with surface made of high purity mineral glass
  • Measurement of air quality based on the content of hydrocarbons according to the guidelines of the UBA (German Federal Environmental Agency)
  • Additional display of the equivalent  CO2 value (approx. 400 ppm to over 3000 ppm CO2)
  • Bargraph with 15 LEDs is easy to read from a distance
  • In case of poor air quality, a red light ring appears around the sensor (“corona light”)
  • In case of further deterioration of air quality, the sensor beeps (can be switched off by button)
  • Operation on power supply LCN-NUI (included in delivery)

Scope of delivery:

LCN-GSA4W (air quality sensor)
LCN-UPS (universal sensor module)
LCN-NUI (power supply unit)
