Increased quality criteria and technical developments in smoke alarms are represented on the market by the new Q test mark. The new Q label is an independent and manufacturer-neutral quality mark for high-quality smoke alarms that have been specially tested for long-term use. The latest generation of Gira smoke alarms meet the criteria of the new Q label quality mark. The smoke alarms work according to the photoelectric scattered light principle without radioactive substances. The smoke alarms detect smoke development in good time and warn before the smoke concentration can become dangerous for people. The alarm is triggered by a loud pulsating alarm tone and a flashing LED. Features Only for use in private residential units or residential-like areas in accordance with DIN 14676.
