EN 14604 is the core European safety standard for residential smoke alarms, mandatory for legal sales and installation across European markets. TÜV Rheinland EN 14604 certification represents professional third-party quality verification. It confirms that smoke alarms meet strict international standards in detection sensitivity, alarm volume, service durability, and anti-false alarm performance.

To deliver fully compliant and trustworthy fire safety solutions, Hangzhou Deheng Smart Electric Co.,Ltd. launches two mainstream smoke alarm series, both fully certified with TÜV Rheinland EN 14604 standards. Every device from these two lines strictly complies with EU CPR regulations and global fire safety benchmarks.
