Hikvision AX Hybrid Pro DS-PM2-P PSTN Communication Module with Wired Alarm Panel Support, PSTN Communication, Plug-In Module Design

Model: DS-PM2-P

Who This Is For

Property managers specifying alarm systems for sites where internet connectivity is unreliable, unavailable, or simply not trusted as a sole communication path will find the DS-PM2-P fills a critical gap in the Hikvision AX Pro hybrid panel setup. This plug-in PSTN communication module connects directly into a compatible AX Pro panel and adds a traditional phone line as a signalling channel, allowing the panel to report alarm events to a central monitoring station over the PSTN network. It suits commercial sites, rural properties, and heritage buildings where broadband infrastructure is inconsistent, as well as installers who specify PSTN as a backup path alongside IP or GSM communications. The module slots in cleanly without additional enclosure space, keeping the installation tidy and the panel's footprint unchanged. If your panel specification calls for PSTN reporting capability, this is the dedicated module that enables it.

What This Module Actually Does

Who Buys This Module

• Alarm Installers Specifying Dual-Path Signalling: Installers who need a PSTN backup alongside IP or 4G on AX Pro panels to satisfy monitoring station grade requirements or insurance conditions.
• Rural and Remote Site Integrators: Sites without reliable broadband or mobile coverage that still have an active phone line - the DS-PM2-P makes PSTN the primary or sole communication path for those installations.
• Commercial Property Managers Upgrading Existing Panels: Properties already wired with PSTN infrastructure looking to add or retain phone line reporting when transitioning to an AX Pro hybrid panel.
• Monitoring Stations and Their Preferred Installers: Stations that still accept or mandate PSTN as a signalling protocol for certain customer accounts will direct installers toward this module to enable compatible reporting formats.

Honest Assessment

The DS-PM2-P does one thing well: it adds a dedicated, clean PSTN communication channel to an AX Pro panel without complicating the installation. The plug-in form factor means it takes up a module slot, gets configured through the existing panel interface, and does not require any additional hardware. For sites with an active phone line and a requirement for PSTN-based alarm reporting, this is the correct and straightforward solution within the AX Pro ecosystem. What it will not do is substitute for IP or 4G communication on sites where the phone line has already been decommissioned or where the monitoring station has moved entirely to IP-based protocols - in those cases, the relevant IP or 4G communication module is the appropriate choice. It also does not add any detection, processing, or panel expansion functions beyond the communication path itself. The DS-PM2-P is available through Security Australia as a stocked accessory for AX Pro hybrid panel builds.

Before You Buy

Quick Fit Check

• Good match if: You are installing or upgrading an AX Pro hybrid panel at a site with an active analogue phone line and the monitoring station accepts or requires PSTN as a signalling path.
• Good match if: The site specification calls for dual-path communication and IP or 4G is already covered by another module - the DS-PM2-P adds PSTN as the second independent channel using an available panel bay.
• You may need a different model if: The site has no active PSTN line or the monitoring station operates on IP-only protocols - a 4G or IP communication module for the AX Pro panel will be the appropriate choice instead.

Real-World Scenarios

How It Compares

• Choose this if: The site has an active analogue PSTN line and you need to enable phone-line alarm reporting on an AX Pro panel - either as the sole path or as a backup alongside IP or 4G.
• You may need a different model if: The site's copper phone line has been decommissioned or the NBN connection type does not support analogue signalling - a 4G or IP communication module for the AX Pro panel will provide a suitable alternative path without relying on PSTN infrastructure.
• Pairs well with: An AX Pro IP or 4G communication module installed in a second bay on the same panel, creating a dual-path setup where PSTN and IP or cellular operate as independent backup channels.

Common Questions

1. Will the DS-PM2-P work with any Hikvision alarm panel, or only the AX Pro series?

   Only the AX Pro hybrid panel series. The DS-PM2-P is designed as a plug-in module for the AX Pro platform specifically and slots into the dedicated module bay on compatible AX Pro panels. It is not a standalone dialler and cannot be wired into older Hikvision panels or third-party panels that lack an AX Pro-compatible module bay.

2. Does this module work on NBN connections?

   It depends on the NBN connection type. NBN services delivered over fibre-to-the-node (FTTN) or fibre-to-the-curb (FTTC) typically retain an active analogue signal on the copper pair, which the DS-PM2-P can use. However, FTTP, FTTB, and HFC connections generally do not carry an analogue phone signal, meaning there is no compatible line for the module to use. Always confirm the NBN technology type at the site before specifying PSTN as the communication path.

3. Can the DS-PM2-P and a 4G or IP module both be installed in the same AX Pro panel?

   Yes, provided the panel has 2 available module bays. Multiple communication modules can be fitted to the AX Pro panel simultaneously, allowing PSTN and 4G or IP to operate as independent signalling paths. This is the recommended configuration for sites requiring dual-path reporting to a monitoring station, as it provides genuine redundancy rather than reliance on a single communication channel.

4. Does this module require its own power supply?

   No. The DS-PM2-P draws power from the AX Pro panel through the module bay connection. No separate power supply, transformer, or additional wiring is needed beyond the phone line termination at the panel. This is one of the practical advantages of the plug-in module design over adding a standalone PSTN dialler.

5. What signalling protocols does the DS-PM2-P support for monitoring station reporting?

   The DS-PM2-P communicates using standard PSTN alarm signalling protocols supported by the AX Pro panel. For specific protocol compatibility with your monitoring station's receiver (such as Contact ID or SIA), confirm directly with your monitoring station prior to installation. Security Australia can assist with stocking and availability queries, but monitoring station protocol compatibility is confirmed at the commissioning stage between the installer and the station.

6. Is this module configured through the AX Pro app or through a separate interface?

   Configuration is handled through the standard AX Pro panel setup interface. Once the DS-PM2-P is inserted into the module bay, the panel recognises it and the communication settings - including reporting destination numbers and priority order if multiple modules are installed - are set through the same interface used to configure the rest of the panel. There is no separate app or standalone configuration tool required for the module itself.
