Main Functions
The 94700040 is a wireless smoke sensor that utilizes Zigbee protocol for reliable, low-power communication within IoT networks, enabling seamless integration into smart home and building automation systems. It provides dual alarm modes, triggering both an loud local 85dB buzzer and a simultaneous network alarm to alert the system remotely. The device features an ultra-low standby current (<9μA) and an exceptional 10-year battery life, ensuring long-term, maintenance-free operation for continuous safety monitoring.
Typical Application Scenarios
This sensor is ideally deployed in large-scale Zigbee-based smart home ecosystems, such as those using Amazon Alexa, Samsung SmartThings, or other compatible hubs, for whole-house smoke detection and automation. It is also perfectly suited for commercial buildings, hotels, and apartment complexes where a mesh network of sensors is required for comprehensive coverage, benefiting from Zigbee's robust mesh networking capabilities. Furthermore, its long battery life makes it excellent for use in remote or hard-to-access areas like warehouses, attics, or vacation homes, where frequent battery replacement is impractical.
Technical Features
The device operates on the 2.4GHz frequency band with a transmission power of ≤15dBm, achieving a communication range of up to 100 meters in open air, which is suitable for forming stable mesh networks. It is powered by a single CR123A battery (DC 3V) and includes a low-battery indication at 2.6V±0.2V, providing users with ample warning for proactive maintenance. With compact dimensions of Ø90x37 mm, a UV-stabilized ABS housing, an operational temperature range of -10°C to +55°C, and an alarm current of <30mA, it combines durability, energy efficiency, and reliable performance for professional and residential safety applications.
