For visualising messages, warnings and CO2 values in the interior

Light signals are an optimal way to discreetly indicate various warnings or conditions in the interior of the modern smart building – e.g. such as an occupied conference room or CO2 levels that are too high.

With the product innovation Cala KNX IL, Elsner Elektronik provides a KNX colored light that is designed for a wide range of applications in the KNX system. The design is coordinated with the switch series Cala and convinces with a flat construction and elegant glass surface. Available is a variant for standard 55 mm frames and one for the Swiss 60 mm system.

The luminous field of the flat device lights up green, yellow or red. This can be used to visualize various messages and warnings. Flashing is also possible. When switched off, the glass surface in the switch frame integrates inconspicuously into the interior.

Clever control of indoor air quality

A special application is the visualization of air quality with the CO2 indicator light Cala KNX IL CO2. An integrated sensor switches the light field from green to yellow to red depending on the carbon dioxide content of the air. In this way, Cala KNX IL CO2 can contribute to a healthy indoor climate by the color prompting manual ventilation or by starting automatic ventilation via the KNX bus.

Not only can the integrated ventilation control be configured via KNX, but also the status for switching off the light at night and much more. In addition, all other control options for the light field are available with Cala KNX IL CO2. Thus, safety-relevant messages such as fire or burglary alarms can be additionally displayed.
