360°Smoke Inlet

Innovative 360° circular smoke inlet structure breaks the traditional detection blind area. No matter which direction the smoke spreads, it can be quickly captured. The smoke inlet channel of Heiman smoke alarm is optimized with smaller air resistance and faster response , striving for precious time for fire early warning. It is an "all-round sentinel" for home safety.
Dual wavelength

Equipped with red light + infrared dual-wavelength detection chip, it is the core technical highlight of Heiman smoke alarm. The dual wavelengths work together to accurately distinguish fire smoke from interfering sources such as cooking fumes and aroma steam, reducing the false alarm rate. Whether it is the thick black smoke from open fire or the thin smoke from smoldering, it can be accurately identified, avoiding the trouble caused by invalid alarms.
Proactive Fault Alert - Preventing Risks Before They Escalate

It monitors the operating status of internal components in real time, and immediately issues audio-visual alerts when the equipment is abnormal (such as sensor failure, low battery voltage) to proactively avoid blind spot risks.
One-Touch Self-Check - Safety Status at Your Fingertips

No complex steps! Just press the button to check if the alarm is working properly. Perfect for busy parents, seniors, or anyone who wants simple, regular safety checks—no technical skills needed.
Peel & Stick - Protection in 30 Seconds

No drilling or wiring needed. Strong adhesive backing allows secure installation in seconds. Ideal for rentals, dorms, and older homes – instant safety, zero effort.
