Heiman HM2SA-5W-T Smoke Detector – reliable fire protection with wireless interconnection

The Heiman HM2SA-5W-TT is a compact, photoelectric smoke detector with a wireless interlink function. It has been specially developed for use in living rooms, hallways, or bedrooms and can be connected with other compatible detectors via 868 MHz. This creates a comprehensive safety system that triggers an alarm on all connected devices simultaneously in an emergency.

The integrated 10-year battery ensures long-term operational readiness without the need for battery changes. A self-test mode, status LED, and acoustic signals for low battery voltage or faults provide additional everyday safety.
