Product SKU: Hikvision DS-PM1-I8O2-H
Product Overview
The Hikvision DS-PM1-I8O2-H AX Hybrid PRO RS-485 Wired Input Expander is an expansion module designed for compatible Hikvision AX Hybrid PRO hardwired alarm systems. It adds 8 wired inputs and 2 outputs to supported alarm controller installations, helping installers expand zone capacity and output control for larger or more structured intrusion alarm projects. The RS-485 wired connection makes it suitable for professional hardwired alarm layouts where reliable communication between the controller and expansion hardware is required. This expander is well suited to homes, offices, retail stores, warehouses, workshops, clinics and commercial premises requiring additional wired alarm zones and output functions.
Key Capabilities
8 Wired Input Expansion
The DS-PM1-I8O2-H adds 8 wired alarm inputs to compatible AX Hybrid PRO systems, allowing additional detectors, contacts or input circuits to be connected.
2 Output Support
The module provides 2 outputs for compatible alarm output functions, giving installers extra flexibility for sirens, relays or other configured alarm responses.
RS-485 Wired Communication
RS-485 wired communication supports stable connection to compatible AX Hybrid PRO alarm controllers in structured hardwired installations.
AX Hybrid PRO Expansion
The expander is designed for compatible Hikvision AX Hybrid PRO systems where additional wired inputs and outputs are required beyond the controller’s base capacity.
Professional Wired Alarm Layouts
This module is useful for larger alarm systems, multi-area sites and retrofit projects where hardwired detector expansion is preferred.
Best For
- AX Hybrid PRO Alarm Systems: Suitable for compatible Hikvision hardwired alarm controller installations requiring additional zones and outputs.
- Commercial Alarm Expansion: Practical for offices, retail sites, clinics, warehouses and workshops needing extra wired inputs.
- Residential Wired Alarms: Useful for larger homes or villas with multiple doors, windows, motion detectors and perimeter zones.
- Retrofit Alarm Projects: A good option where existing wired zones need to be retained or reorganised in a modern AX Hybrid PRO system.
- Output Control Applications: Best where extra alarm outputs are needed for compatible sirens, relays, strobes or system-triggered functions.
Why Choose the DS-PM1-I8O2-H
The DS-PM1-I8O2-H is a practical choice when a Hikvision AX Hybrid PRO alarm system needs additional hardwired zone capacity without replacing the main controller. By adding 8 wired inputs and 2 outputs through RS-485 communication, it helps installers expand alarm coverage across larger homes, offices, warehouses and commercial sites. It is especially useful where the system design includes multiple detectors, perimeter contacts or output-triggered devices across different areas. For alarm systems supplied through Security Wholesalers, this expander should be selected after confirming controller compatibility, RS-485 cable route, zone requirements, output functions, power supply and enclosure location.
Buyer Decision Tips
Buyer Tip: Choose the DS-PM1-I8O2-H when you need to add 8 wired inputs and 2 outputs to a compatible Hikvision AX Hybrid PRO alarm controller. If the site uses a fully wireless AX PRO hub, choose a compatible wireless input expander instead.
Installation Tip: Confirm controller compatibility, RS-485 wiring, address configuration, power requirements, input types, EOL resistor settings, output functions and enclosure placement before installation.

Ideal Use Cases
Additional Wired Zones
Use the expander where a compatible AX Hybrid PRO controller needs extra zones for additional detectors or contacts.
Commercial Alarm Systems
Suitable for offices, retail stores, clinics and commercial premises where multiple alarm points need wired integration.
Warehouse and Workshop Protection
Practical for larger internal areas requiring several PIRs, contacts, panic points or output devices across the site.
Residential Alarm Expansion
A good option for larger homes where more hardwired door, window and internal detection zones are required.
Hardwired System Upgrades
Useful where an alarm upgrade keeps existing wired devices and expands them into a compatible AX Hybrid PRO platform.
Choosing the Right Model
- Choose this model if: You need an RS-485 wired expansion module with 8 inputs and 2 outputs for a compatible Hikvision AX Hybrid PRO alarm controller.
- Choose a different module if: The site uses AX PRO wireless, needs 16 wireless-converted inputs, requires a full alarm controller, or needs a detector rather than an expansion module.
- Check before ordering: Confirm controller compatibility, required number of inputs and outputs, RS-485 cable route, input wiring type, EOL resistor settings, output device requirements and enclosure space.
FAQs
- What is the Hikvision DS-PM1-I8O2-H used for?
The DS-PM1-I8O2-H is used as a wired input and output expander for compatible Hikvision AX Hybrid PRO alarm systems. It adds extra wired alarm inputs and outputs to the system through RS-485 communication. - How many inputs does the DS-PM1-I8O2-H provide?
The DS-PM1-I8O2-H provides 8 wired inputs. These can be used for compatible wired alarm devices such as PIR detectors, magnetic contacts, reed switches, panic buttons or other supported input circuits. - How many outputs does this expander provide?
The expander provides 2 outputs for compatible alarm output functions. These may be used for devices such as relays, sirens, strobes or other output-triggered alarm functions depending on the final system configuration. - Does this module use RS-485?
Yes. The DS-PM1-I8O2-H uses RS-485 wired communication with the compatible AX Hybrid PRO alarm controller. Correct cabling, addressing and installation practices are important for reliable operation. - Is this for AX PRO wireless systems?
No. The DS-PM1-I8O2-H is intended for AX Hybrid PRO wired alarm system expansion. If the project uses a wireless AX PRO hub, choose a compatible AX PRO wireless expander or input transmitter instead. - Can this be used in commercial alarm systems?
Yes. The 8-input and 2-output design is suitable for commercial alarm systems where additional wired zones and output functions are required. For systems supplied through Security Wholesalers, the installer should confirm the full zone and output plan before ordering. - Where should the expander be installed?
Install the expander in a protected equipment location or enclosure where the RS-485 cable, detector wiring, output wiring and service access can be managed safely and neatly. It should be positioned according to the final alarm system design. - What should be checked before installation?
Before installation, confirm the compatible AX Hybrid PRO controller, RS-485 cable route, addressing method, input types, EOL resistor values, tamper requirements, output functions, power supply, enclosure space and whether additional expanders are required for the final zone count.
