Low Current Output Control
The module is designed for low-current relay output applications, supporting compatible alarm-triggered control functions and external device signalling.
Speed-X Bus Communication
Speed-X Bus communication supports reliable wired connection to compatible AX Hybrid PRO controllers in professional alarm installations.
6–30V Power Support
Wide voltage support gives installers flexibility when integrating the expander into compatible alarm power and equipment layouts.
5A Relay Output Capability
The 5A relay output rating supports compatible output switching applications, subject to correct wiring, load type and installation requirements.
Best For
- AX Hybrid PRO Alarm Systems: Suitable for compatible Hikvision hardwired alarm installations requiring extra relay outputs.
- Commercial Alarm Output Control: Practical for offices, warehouses, retail stores and workshops needing additional alarm-linked relay functions.
- Siren and Strobe Integration: Useful where the alarm design requires extra output paths for compatible warning or signalling devices.
- Automation Triggering: A good option where supported external systems or control inputs need relay-triggered alarm actions.
- Hardwired Alarm Expansion: Best where a compatible wired controller needs more output capacity without replacing the main alarm panel.
Why Choose the DS-PM1-O4L-H
The DS-PM1-O4L-H is a practical choice when a Hikvision AX Hybrid PRO alarm system needs additional wired relay outputs for a more flexible site design. With 4 low-current relay outputs, Speed-X Bus communication and 6–30V support, it helps installers add output functions for compatible sirens, strobes, relays or alarm-linked control workflows. The 5A relay output capability provides useful switching flexibility when matched correctly to the connected device and wiring method. For alarm systems supplied through Security Wholesalers, this expander should be selected after confirming controller compatibility, relay load requirements, Speed-X Bus wiring, power supply and the final output logic.
Buyer Decision Tips
Buyer Tip: Choose the DS-PM1-O4L-H when you need 4 additional wired relay outputs for a compatible Hikvision AX Hybrid PRO alarm controller. If the site uses a wireless AX PRO hub, choose a compatible wireless relay module instead.
Installation Tip: Confirm Speed-X Bus compatibility, relay load rating, power supply, connected device type, output programming, enclosure position and electrical safety requirements before installation.

Choosing the Right Model
- Choose this model if: You need a wired 4-way low current relay expander with Speed-X Bus, 6–30V support and 5A relay output capability for a compatible Hikvision AX Hybrid PRO controller.
- Choose a different module if: The site uses AX PRO wireless, requires input expansion, needs more than 4 relay outputs, requires high-current switching beyond the module rating, or needs a detector rather than an output expander.
- Check before ordering: Confirm controller compatibility, Speed-X Bus cabling, relay load, power supply, connected output devices, enclosure space, output logic and any electrical compliance requirements.
FAQs
