Hikvision AX PRO Series DS-PM1-O1L-WB Relay Module

Model: DS-PM1-O1L-WB

Who This Is For

For installers and integrators expanding a Hikvision AX PRO wireless alarm system who need to trigger external devices - sirens, strobe lights, electric locks, or auxiliary equipment - from within the same ecosystem. The DS-PM1-O1L-WB Relay Module adds a single wireless relay output to the AX PRO network, pairing over 433 MHz without additional wiring back to the control panel. It suits residential and light commercial installs where a device needs to respond automatically to an alarm event or be switched remotely via Hik-Connect. It is also a practical choice when a hardwired output from the main panel is not feasible due to distance or building layout, and the compact 38 x 25 x 18 mm housing means it can sit discreetly near the load it controls rather than at the panel.

What This Module Actually Does

Who Buys This Module

• AX PRO System Integrators: Adding output capability to an existing AX PRO deployment where the panel's onboard outputs are already allocated, or where the load is physically remote from the panel.
• Retrofit Installers: Upgrading older wired alarm systems to AX PRO wireless while reusing existing hardwired sirens or strobes by placing the relay module adjacent to the load and pairing it wirelessly to the new panel.
• Small Business Owners: Needing to tie auxiliary equipment - roller door openers, warning lights, or audible sounders - into their AX PRO alarm events without rewiring the premises.
• Residential Installers: Connecting a hardwired outdoor siren or garden light to the AX PRO system in a home where routing cable back to the panel through finished walls is not feasible.

Honest Assessment

The DS-PM1-O1L-WB does one thing well: it adds a wireless, remotely switchable relay output to a Hikvision AX PRO system with tamper monitoring included. The NO/NC configuration at up to 36 VDC and 5 A covers the vast majority of auxiliary devices found in residential and light commercial alarm installs, and the wide 7-24 VDC input means power is rarely a problem. The compact housing keeps installation tidy regardless of where the module is placed near the load. What it will not do is operate outside the AX PRO ecosystem - it is not a standalone relay, and it cannot pair with other Hikvision product lines or third-party panels. It provides only 1 relay output, so applications requiring multiple independent switched outputs will need additional modules. If the goal is hardwired integration with an existing conventional panel, a different wired output expander would be more appropriate. The DS-PM1-O1L-WB is available through Security Australia for sites already committed to the AX PRO platform.

Before You Buy

Quick Fit Check

• Good match if: You are expanding an existing AX PRO wireless alarm system and need to trigger a hardwired siren, strobe, or electric lock from an alarm event without running control cable back to the main panel.
• Good match if: You need remote manual switching of an auxiliary device via Hik-Connect on top of automatic alarm-event triggering, and the load operates within the 36 VDC, 5 A relay rating.
• You may need a different model if: Your installation requires multiple independent relay outputs at a single location - in that case, a multi-output wired expander module will be more practical and cost-effective than multiple individual DS-PM1-O1L-WB units.

Real-World Scenarios

How It Compares

• Choose this if: Your site already runs a Hikvision AX PRO wireless panel and you need to add a triggered or remotely switched output for a siren, strobe, or electric lock without running wiring back to the panel.
• You may need a different model if: You require multiple independent relay outputs at one location - a wired multi-output expander module will handle that more efficiently than stacking individual wireless relay modules.
• Pairs well with: AX PRO wireless panel, wireless detectors, and wired sirens or strobes used as the controlled load.

Common Questions

1. Will the DS-PM1-O1L-WB work with any Hikvision alarm panel, or only AX PRO?

   Only AX PRO panels. The DS-PM1-O1L-WB communicates over 433 MHz using the proprietary AX PRO wireless protocol and cannot be enrolled into other Hikvision panel ranges or third-party alarm systems. Confirm your panel model is within the AX PRO series before purchasing.

2. Does this module need its own power supply on-site?

   Yes. The DS-PM1-O1L-WB requires a local DC power supply between 7 VDC and 24 VDC at the installation point. Power is not transmitted wirelessly from the panel. In most cases, the same 12 V or 24 V supply used for the connected load can also power the module, provided the supply has sufficient current capacity.

3. Can I use this to control a 240 VAC device such as a mains-powered siren?

   No. The relay output is rated for DC circuits only, up to 36 VDC and 5 A. It is not rated for 240 VAC mains switching. For mains-powered devices, an additional appropriately rated contactor or relay would be required - this is outside the scope of the DS-PM1-O1L-WB on its own.

4. Does this module provide tamper protection?

   Yes. There is 1 dedicated tamper alarm input configured as NO or NC. If the module is opened or removed from its mounting surface, a tamper alert is transmitted to the AX PRO panel, which can then notify the monitoring centre or generate an alert through Hik-Connect - the same as any other supervised AX PRO device.

5. Will this work for gate or door release in an access control scenario?

   It can, within defined limits. The NO relay output can be wired to most gate controllers or electric strike inputs that accept a dry contact trigger. However, the DS-PM1-O1L-WB does not provide any credential reading, user management, or access logging - it simply switches the relay on command. For a full access control deployment, a dedicated access control reader and controller is the appropriate product type. This relay module suits simple one-button remote release applications within an existing AX PRO alarm setup. The DS-PM1-O1L-WB is stocked by Security Australia for AX PRO system expansion.

6. How many of these modules can I add to one AX PRO panel?

   The number of DS-PM1-O1L-WB units you can enroll is governed by your specific AX PRO panel's total wireless device capacity, not by the module itself. Check your panel's published specifications for total peripheral device slots. Each module occupies one enrollment slot regardless of whether it is being used as an auto-triggered output or a manually switched relay.
