HIKVision RS485 Input Expander

The Hikvision DS-PM-RS18 is a wired expansion module designed for use with Hikvision AX Hybrid security alarm systems. It communicates with the alarm control panel through an RS-485 bus, allowing installers to extend system capacity and connect additional wired alarm accessories.

The module is suitable for larger residential, commercial, and industrial security applications where extra inputs or outputs are required. It enables integration of additional field devices such as detectors, alarm accessories, and automation equipment while maintaining reliable wired communication over the RS-485 network.

The RS-485 architecture provides stable communication over longer cable distances, making the DS-PM-RS18 suitable for centralized alarm installations where multiple expansion modules are required. It is designed for professional installations requiring flexible system expansion and integration with Hikvision hybrid alarm panels.
