Runidur Fire Alarm – 10-Year Battery Photoelectric Smoke Detector with Test/Silent Button (US-SM01 3-Piece)

Meet the Runidur Fire Alarm, a compact, power-saving smoke detector designed for homes that value dependable protection with minimal maintenance. Powered by a CR123A lithium battery, this unit delivers up to 10 years of service life, helping you avoid frequent battery changes while offering continuous 24/7 monitoring. The horn is loud enough to provide a clear fire warning, clocking in at over 85 dB, so you can react quickly if smoke is detected.

Designed with a photoelectric sensor, the detector emphasizes quick smoke detection in everyday environments. A built-in dust-proof isolation board and a dedicated development chip work together to minimize false alarms and maintain sensitivity across a range of conditions. The result is a reliable, low-maintenance device that blends into home interiors without drawing attention to itself.

Compact, unobtrusive design

At just 3.34 inches by 0.93 inches, the Runidur detector remains slim and discreet on ceilings or walls. It ships with two installation materials, making fast mounting straightforward whether you’re upgrading an existing system or adding new coverage in a hallway, kitchen, or living area.

Test, silence, and user-friendly operation

The unit includes a test/silent button for straightforward checks and quick silencing if needed. After activation, hold the button for a moment to hear the audible cue and see the LED illuminate. If there is no danger, pressing the button again can silence a sounding alert, helping you confirm status without panic.

Durable housing for everyday use

The detector is housed in upgraded flame-retardant ABS plastic, providing flame resistance, high-temperature tolerance, and corrosion resistance. This construction supports dependable performance in a range of home environments while maintaining a sleek, modern look.

Overall, the Runidur Fire Alarm aims to combine long-term power savings with reliable smoke detection in a compact package. It presents a practical option for homes seeking a balance between continuous protection and straightforward installation. While results can vary with layout and conditions, the combination of a 10-year battery, a photoelectric sensor, and a robust design makes it a compelling choice for everyday safety planning.
