Import Battery Powered Photoelectric Radio Smoke Alarm — Buy in Bulk from Supplier in China

The battery powered photoelectric radio smoke alarm from Shenzhen Anjisi Intelligent System Technology Co., Ltd. uses a photoelectric sensor to detect visible smoke particles, triggering an audible alert at the earliest sign of fire. The unit operates on battery power, eliminating the need for hardwiring and allowing installation in locations without fixed electrical circuits. Its compact form factor, typically under 120 mm in diameter and 40 mm in depth, enables discreet mounting on ceilings or walls in residential, office or light commercial environments.

Photoelectric alarms are particularly effective at detecting smouldering fires, which produce larger smoke particles, and are less prone to false alarms from steam or cooking fumes compared to ionisation types. Standard models in this category use a 9V alkaline battery or 10-year lithium cell, with a typical operating temperature range of 0°C to 40°C and humidity tolerance up to 95% non-condensing. The alarm sound level meets the standard minimum of 85 dB at 3 metres, ensuring audibility in noisy or large spaces.

These alarms are widely used in homes, small offices, guesthouses and retail spaces where early fire detection is critical for occupant safety. Buyers sourcing from Shenzhen Anjisi Intelligent System Technology Co., Ltd. should confirm battery type, expected lifespan and compatibility with local fire safety regulations. The radio-linked feature, where present, allows multiple units to synchronise alerts across a building, providing a coordinated response to smoke detection.

Shenzhen Anjisi Intelligent System Technology Co., Ltd. is based at No.175 Dongbin Road, Nanshan District, Shenzhen, China, and operates as an imported-tier supplier specialising in intelligent safety systems. The company’s profile indicates it is classified under the harbor trust tier, which reflects a baseline level of verification for international trade.

While the supplier’s response rate and average response hours are currently unrecorded, its listed address and focus on fire safety devices position it as a provider of export-ready products for global buyers. The absence of additional details, such as certifications or production capacity, means buyers should request these specifics directly to assess suitability for their procurement needs.
