These smoke detectors were designed by Finnish designers HARRI KOSKINENA and PAOLY SUHONEN, who focused primarily on modernity and design.

The optical smoke detectors were made primarily for use in the home.

The advantage of the Chrom Square detectors is their easy installation, which takes only a few seconds. Unlike other smoke detectors, the entire front surface of the Chrome Square alarm acts as a test button. This type of detector uses photoelectric detection technology to sense smoke. This technology consists of sensing scattered visible smoke particles through infrared beams. In order to ensure the correct operation of the detector, the so-called automatic diagnosis and control function has been included in the device.
