## Long description

The Esylux Protektor K smoke detector is a mains-powered unit designed for continuous smoke detection in residential and small commercial environments. It operates from 230V mains power and includes a 9V backup battery to maintain functionality during mains interruptions.

Advantages
The Protektor K combines mains operation with a battery backup, ensuring detection and alarm signalling even during temporary power loss. The integrated relay driver enables straightforward integration with alarms, ventilation control, or notification systems without additional modules. Interconnectivity for up to 30 detectors permits scalable coverage and simultaneous alerts across a whole dwelling or small facility. The detector is designed for straightforward ceiling or wall mounting and for reliable optical smoke detection.
