HIKVISION AX HYBRID PRO
Commercial Security Expansion with High-Density Zone Integration
The DS-PM1-I8O2-H is a high-performance wired zone expander specifically engineered for the HIKVISION AX Hybrid Pro intrusion alarm control panel. Designed for demanding commercial, retail, and residential installations requiring reliable hardwired detector integration, the DS-PM1-I8O2-H expands overall system capacity while delivering robust, tamper-resistant perimeter protection and centralized output control across long-distance cable runs.
Zone Capacity
8 Hardwired Inputs
Bus Protocol
Dual Speed-X (900m)
ECL Protection
3EOL Multi-State
Auxiliary Output
12VDC / 500mA Power
Advanced Speed-X Bus Communication & Cascade Topology
Utilizing proprietary high-speed RS-485 architecture, the HIKVISION DS-PM1-I8O2-H establishes a stable, interference-resistant connection to the control panel at distances up to 900 meters. Equipped with dual Speed-X bus ports (1 input and 1 output), the module supports direct expansion cascading, allowing installers to link subsequent expanders along a single bus line up to another 900m without complex intermediate hubs. Comprehensive 3EOL wiring configurations deliver enhanced signal detection for alarm triggering, anti-masking, short circuits, and tamper monitoring across every zone.
3EOL Signal & Tamper Monitoring
Supports sophisticated 3EOL resistor wiring (Alarm 1kΩ, Tamper 1kΩ, Fault 2.2kΩ) to distinguish between legitimate intrusion signals, physical enclosure tampering, wire masking, and line shorts. Front and rear anti-tamper protection ensures immediate panel alerts if the module is opened or unmounted.
On-Board Collector Outputs & Aux Power
Features 2 collector outputs for triggering external relay modules, strobes, or sirens alongside a dedicated 12 VDC / 500mA auxiliary power output. This eliminates the need for external power supplies when running short-range wired motion sensors or beam detectors.

Which HIKVISION main control panels are compatible with this expander?
The DS-PM1-I8O2-H is designed specifically for compatibility with the HIKVISION AX Hybrid Pro intrusion alarm control panel series using Speed-X bus technology.
How far can I place the expander from the main control panel?
The Speed-X bus protocol supports wiring distances of up to 900 meters from the control panel to the expander. An additional 900 meters can be extended when cascading to the next expander via the output Speed-X port.
Does this expansion module power external detectors?
Yes, it features 1 auxiliary power output providing 9 to 12 VDC at up to 500 mA, which can directly power connected hardwired motion detectors or sensors.
What types of zone states can the DS-PM1-I8O2-H detect?
Thanks to 3EOL connection support, the module can simultaneously detect zone alarm, tamper state, sensor masking, wiring fault, and short-circuit conditions.
