AS5042H Two-port Simple Alarm Unit

The AS5042H Two-port Simple Alarm Unit from Hangzhou Timing Technologies Co. Ltd. is a compact security device designed for small-scale intrusion detection and sensor integration. Measuring 71 x 50 x 13mm, it provides two RJ11 output ports that each connect to a separate sensor or display system, allowing dual-zone coverage from a single controller. The unit outputs a 95dB alarm tone and runs on USB power input with a built-in rechargeable lithium battery that sustains up to 7 days of standby operation. LED indicators display the operational status of each defence area, and the unit triggers an alarm if the case is tampered with or detached.

The ABS case houses the battery, alarm siren, and control circuitry in a footprint smaller than most smartphones. The RJ11 ports use standard telephone-style connectors, which simplifies field wiring and replacement of sensor cables. The code modification function allows users to change device settings or pair new sensors without replacing the entire unit. Low battery indication and external power on/off indication are both standard features, reducing the risk of silent failures during power transitions. The optional 5V/4A power adapter provides a regulated supply for permanent installations where USB host power is unavailable.

Typical buyers include security equipment distributors, property management firms, and small retail chains who need affordable alarm infrastructure for shops, warehouses, and offices. The unit suits applications where two detection zones are sufficient, such as front-door plus stockroom monitoring, or paired motion and door sensors. Importers should confirm whether the AS3X series IR remote keys are included or ordered separately, and verify that the lithium battery meets UN38.3 transport requirements for air freight from Zhejiang province.

Hangzhou Timing Technologies Co. Ltd. is located at 7- Wujin Road, Huangshan Village, Wenyan Town, Xiaoshan, Hangzhou, Zhejiang province, postal code 311258, China. The supplier holds a harbour trust tier on the platform, though its response rate is recorded at 0.00 percent with zero average response hours, which suggests either a new listing, dormant account, or unmeasured communication channel. The address places the company in Xiaoshan district, an industrial zone within greater Hangzhou known for electronics manufacturing and component assembly.

The company's product focus appears to be security and timing devices, as indicated by its name and the alarm unit offering. No verified factory size, year of establishment, revenue figure, or client reference is available in the source data. Buyers should request a current business licence, ISO 9001 certificate if claimed, and a factory audit report before committing to volume orders. Given the zero response metric, initiating contact through multiple channels (email, phone, and platform messaging) is advisable to gauge responsiveness.
