Main Functions
The 94700050 is a smart smoke sensor designed to detect smoke and trigger both a local audible alarm and a remote network alert via Wi-Fi, providing dual-notification for enhanced safety. It operates on a low-power Wi-Fi protocol (802.11b/g/n), allowing it to transmit alarm signals directly to a network without the need for an additional gateway. Its built-in low-power indication system alerts users when the battery voltage drops to 2.6V±0.1V, ensuring timely maintenance and continuous protection.
Typical Application Scenarios
This sensor is ideal for integration into smart home systems, where it can provide real-time smoke detection and send instant notifications to homeowners' smartphones or central monitoring systems. It is also well-suited for use in small commercial spaces such as offices, retail shops, and hotel rooms, where ceiling-mounted, wireless sensors simplify installation and reduce wiring costs. Furthermore, its standalone Wi-Fi capability makes it applicable for retrofitting into existing buildings where conventional wired alarm systems are impractical or too expensive to install.
Technical Features
The device supports 2.4GHz Wi-Fi channels 1-14, with a transmission power of ≤20dBm and a sensitivity of ≥-91dBm, ensuring reliable communication over distances up to 70 meters in open air. It is powered by two CR123A batteries, providing a standby current of just ≤15μA and an operational battery life of approximately 4 months under normal conditions. With compact dimensions of Ø64x51 mm, a loud 85dB buzzer, an ABS UV-stabilized housing, and an operational temperature range of -10°C to +55°C, it combines durability, ease of installation, and effective performance for modern wireless safety applications.
