Hikvision AX Hybrid Pro DS-PM1-O4L-H Wired 4-Way Low Current Relay Expander with Speed-X Bus, 6–30V Support, 5A Relay Output

Model: DS-PM1-O4L-H

Who This Is For

When expanding output control in an AX Pro hybrid alarm system is the priority, the DS-PM1-O4L-H wired 4-way low current relay expander gives installers 4 independently controlled relay outputs on a single module connected via the Speed-X Bus. It is built for security integrators and commercial alarm installers who need to trigger third-party devices - sirens, door strikes, lighting circuits, or access control inputs - directly from the AX Pro panel without relying on the panel's onboard output capacity. The module accepts a wide supply voltage range of 6 to 30V, which means it can be powered from a broad range of existing DC supplies already present on site. With a 5A relay rating per output, it handles most low-to-medium current loads common in Australian commercial and industrial alarm installations without requiring external relay boards or additional wiring complexity.

What This Module Actually Does

Who Buys This Module

• Security Alarm Installers: Adding output expansion to AX Pro panels on commercial sites where more than the panel's onboard outputs are needed to drive sirens, strobes, or door hardware.
• Access Control Integrators: Using relay outputs to trigger door strikes or electromagnetic locks from the AX Pro panel on armed/disarmed events, bridging alarm and access control functions on a single platform.
• Industrial Site Contractors: Installing on sites with existing 24V DC power infrastructure, where the 6-30V input range allows the module to be powered from on-site industrial supply rails rather than adding a dedicated 12V alarm supply.
• Service and Upgrade Technicians: Retrofitting additional relay capacity into existing AX Pro installations where a client has added new devices or zones requiring outputs beyond the panel's original configuration.

Honest Assessment

The DS-PM1-O4L-H does a specific job well: it adds 4 independently controllable 5A relay outputs to a Hikvision AX Pro hybrid panel system via the Speed-X Bus, using a single wired connection and a wide 6-30V input range that suits varied Australian site power configurations. For installers already working within the AX Pro ecosystem, it removes the need for external relay boards and keeps output expansion within the same managed platform. It is available through Security Australia as part of the AX Pro accessories range. Where this module will not help is outside the AX Pro system - it is not a standalone relay controller and has no utility with other panel brands or systems. Installers requiring wireless output expansion, or those working with a different Hikvision panel series, will need a different module type. The 5A relay rating is suitable for most alarm peripherals but should be checked against the actual load specs of connected devices before installation.

Before You Buy

Quick Fit Check

• Good match if: You are expanding output capacity on a Hikvision AX Pro hybrid panel and need to drive additional sirens, door strikes, or lighting control inputs via the Speed-X Bus without adding standalone relay boards.
• Good match if: Your site runs a 24V DC industrial power supply and you need a relay expander that accepts the wider 6-30V input range rather than a module restricted to a standard 12V alarm supply.
• You may need a different model if: Your panel is not part of the Hikvision AX Pro hybrid series - this module is bus-specific and will not function with other panel platforms. Browse the broader alarm expander and accessories range at Security Australia to find a module matched to your panel type.

Real-World Scenarios

How It Compares

• Choose this if: You are working within the Hikvision AX Pro hybrid panel ecosystem and need to expand wired relay output capacity via the Speed-X Bus, with a 5A relay rating that suits most alarm peripheral loads and a 6-30V supply range that fits varied site power configurations.
• You may need a different model if: Your installation requires wireless output expansion, or your alarm panel is not from the Hikvision AX Pro hybrid series - in these cases, a wireless output expander or a bus expander module matched to your specific panel platform will be the more appropriate product type.
• Pairs well with: AX Pro hybrid alarm panels, AX Pro zone expanders, AX Pro wireless detectors and keypads operating within the same Speed-X Bus wired topology.

Common Questions

1. Will this module work with any alarm panel, or is it AX Pro specific?

   It is AX Pro specific. The DS-PM1-O4L-H connects via the Speed-X Bus, which is the proprietary wired bus used by the Hikvision AX Pro hybrid panel series. It will not integrate with panels from other manufacturers or with Hikvision panel lines that use a different bus architecture.

2. How many relay outputs does the DS-PM1-O4L-H provide?

   4 independent relay outputs. Each operates separately, so the panel can assign different trigger conditions and responses to each output channel - for example, one output for a sounder, one for a strobe, one for a door strike, and one for a monitoring input, all operating from the same module.

3. What is the relay output current rating, and will it handle a magnetic lock or door strike?

   Each relay is rated at 5A. Most standard door strikes and smaller electromagnetic locks fall within this rating at steady-state current. However, inductive loads can produce inrush current above their running current, so the actual load specifications of the connected device should be confirmed before connecting. For high-current magnetic locks, check the manufacturer's inrush specs and fit appropriate suppression components if required.

4. Does this module work with a 24V site power supply?

   Yes. The DS-PM1-O4L-H accepts a supply voltage range of 6 to 30V DC, which includes standard 12V alarm supplies and 24V industrial DC supplies. This makes it suitable for sites that run 24V power infrastructure without needing a separate step-down supply for the module.

5. How does the Speed-X Bus connection work for installation?

   The Speed-X Bus carries both data and power over a common wired connection between the AX Pro panel and its connected expander modules. The DS-PM1-O4L-H connects to this bus as a wired expander device, which means the installer runs a single bus cable to the module rather than running separate power and data cables back to the panel. Device addressing and configuration are managed through the AX Pro panel software.

6. Can I use multiple DS-PM1-O4L-H modules on one AX Pro panel to get more than 4 relay outputs?

   Multiple expander modules can be connected to the AX Pro panel via the Speed-X Bus, subject to the panel's total bus capacity and expander slot limitations. Before adding multiple modules, confirm the specific AX Pro panel model's documentation for the maximum number of supported wired expanders and total bus load. The team at Security Australia can assist with capacity planning for larger AX Pro installations.

7. Is the DS-PM1-O4L-H suitable for outdoor mounting?

   No confirmed outdoor IP rating is specified for this module. It is an expander board designed for installation inside a panel enclosure or in a protected indoor location. For any installation in areas exposed to moisture, dust, or temperature extremes, the module should be housed in an appropriate weatherproof enclosure rated for the environment.
