Wireless Smoke Detector

This smoke detector is equipped with a built-in warning indicator light. Once smoke triggers fire detection, the red light will flash continuously together with sound alarm to create dual visual & audio alert, even for users with hearing impairment. Installed on ceiling tops as standard requirement, the flash signal can be clearly seen across rooms, ensuring people spot fire risks quickly day and night without blind monitoring area.

The fire alarm outputs stable 85dB alarm sound within 10 feet, louder than daily conversation and vehicle horn noise. The penetrating tone can spread through multiple rooms of houses or large commercial spaces. Compared with low-volume cheap detectors, its distinct alert avoids being covered by household or factory ambient noise, guaranteeing timely risk notification for all indoor occupants.

Powered by two universal 1.5V AAA batteries, this detector needs no wired wiring, making ceiling installation simpler and faster. It adds intelligent low-battery reminder: the unit will emit short beeps every minute when voltage drops below 2.4V, reminding users to replace batteries promptly to prevent fire monitoring failure caused by dead power supply.

Built-in premium photoelectric sensing module with ultra-high smoke detection sensitivity, it quickly responds to smoldering fires with dense smoke which are common in homes and stores. The sensor accurately identify smoke interference without frequent false alarms, maintaining stable detection performance from -10℃ to 55℃ to fit diverse indoor commercial and residential environments.

Ultra-low standby current below 10μA extends battery service cycle, while alarm current is controlled under 150mA. Compact round ceiling-mounted design suits multiple sites: family apartments, retail shops, dining restaurants and industrial factories. It meets general indoor fire safety standards, offering reliable 24/7 smoke monitoring for both residential daily safety and commercial property fire prevention.
