AS5224H / AS5228H Multi-functional Alarm Unit

The AS5224H / AS5228H Multi-functional Alarm Unit from Hangzhou Timing Technologies Co. Ltd. is a centralised alarm controller designed for commercial and industrial security networks. It provides four or eight RJ11 output ports for direct sensor or display system connections, plus two online RJ12 ports that enable cascading multiple units into larger central control systems of 12 through 32 ports. A dedicated external remote RJ12 port supports long-distance integration with devices such as the ES521IR external signal unit. The metal enclosure measures 185 x 80 x 36mm and houses an alarm siren rated at 100 dB. A built-in rechargeable lithium battery delivers up to seven days of standby operation with low-battery indication, while tamper detection triggers an alarm if the unit is detached from its mounting.

The unit's metal case provides electromagnetic shielding and physical durability for rack or wall-mounted installations. LED indicators display the operational status of each defence zone independently, allowing rapid visual diagnostics without network software. Short-circuit protection is built into the power input stage, reducing risk of field wiring faults. The code modification function permits on-site programming of zone configurations, supporting customised installation layouts. Optional WiFi or Bluetooth reception can be factory-configured for wireless integration. The standard power input is DC, with an optional 5V/8A adapter available. Accessory compatibility extends to AS3X series IR remote keys and RJ-2 interconnect cables, forming a modular ecosystem around the base controller.

Typical buyers include security system integrators, commercial building contractors, and industrial facility managers deploying multi-zone intrusion detection. The scalable architecture suits warehouses, retail chains, and manufacturing plants where phased expansion is common. The RJ11 sensor outputs accept standard contact-closure devices, while the RJ12 cascade topology reduces wiring complexity in large installations. Importers should confirm Incoterms, minimum order quantities, and lead times directly with Hangzhou Timing Technologies Co. Ltd., as these are not stated in the source data. CE or FCC compliance documentation should be requested if required for destination-market certification.

Hangzhou Timing Technologies Co. Ltd. is located at 7 Wujin Road, Huangshan Village, Wenyan Town, Xiaoshan, Hangzhou, Zhejiang Province, 311258, China. The company holds a Harbor trust tier on its marketplace profile, with a reported response rate of 0.00 percent and an average response time of zero hours. These metrics suggest the profile may be newly published or that response data has not yet accumulated, so buyers should verify current contact responsiveness before relying on quoted turnaround times. The supplier's specialisation centres on alarm and security electronics, as evidenced by the AS-series product line and accessory ecosystem including IR remotes and external signal repeaters.

The listing provides functional and parametric detail but omits manufacturing certifications such as ISO 9001, environmental compliance (RoHS/REACH), and specific export licences. No factory audit information, employee count, or annual revenue figures are disclosed. Buyers evaluating this supplier should request quality management documentation, sample evaluation protocols, and references from prior OEM or integrator clients. The address in Hangzhou's Xiaoshan district places the company within a mature electronics manufacturing corridor with established logistics links to Ningbo and Shanghai ports, though this geographic advantage should not substitute for verified shipping and customs support capabilities.
