Complete SDA Intercom System for Multi-Home Support, Safety & 24/7 Communication

Creating a reliable and effective Intercom Solution NDIS for Specialist Disability Accommodation (SDA) is more than installing intercom devices — it is designing a communication ecosystem that ensures safety, independence, and rapid response during emergencies. SDA residents often have diverse accessibility requirements, and many rely heavily on their support workers, especially in High Physical Support (HPS) environments. This makes a robust, long-range, and uninterrupted intercom system a critical part of SDA home design.

Digital Home Systems works closely with SDA builders, SIL providers, and disability accommodation managers to design advanced communication solutions tailored to NDIS standards. You can explore our full range of smart intercom technologies here:

This expanded guide provides a comprehensive look at how we designed a customised Intercom Solution NDIS suitable for a cluster of four SDA homes, each with different accessibility classifications but all connected to one central support worker. This article is intentionally in-depth to help developers, providers, and project managers understand the full scope, design considerations, hardware choices, cabling strategies, and compliance expectations involved in building a future-ready SDA intercom network.

Understanding the Purpose of an Intercom Solution NDIS in SDA Environments

An Intercom Solution NDIS is not just a communication device — it is a life-safety system. SDA participants must be able to contact support workers quickly and effortlessly, particularly during emergencies. Whether the resident is non-verbal, has limited mobility, uses assistive technology, or relies on wearable pendants, the intercom system must accommodate their needs without complexity or delays.

Several NDIS and SDA requirements influence how an Intercom Solution NDIS should be designed:

  • Accessibility: Residents of varying ability levels must be able to activate calls easily.

  • Emergency Readiness: The system must support emergency call triggers such as pendants, wall buttons, or automation sensors.

  • Power Resilience: Communication must continue during blackouts, as per NDIS safety guidelines.

  • Assistive Technology Integration: Devices like pull cords, fall detectors, smoke sensors, and door contacts must be linkable.

  • SDA Layout Considerations: Multi-home SDA properties often separate residents and support workers, requiring a long-range intercom network.

  • Data Logging: For incident reporting and compliance, systems should record call times, response times, and call durations.

Digital Home Systems has designed numerous solutions following these principles. For a broader view of how we integrate smart automation across SDA developments, you can also explore:

A high-quality Intercom Solution NDIS elevates both safety and independence for residents while giving support teams the reliability they need to deliver timely care.

Project Overview: Designing a Multi-Home Intercom Solution NDIS for Four SDA Dwellings

In this particular project, the client was developing four SDA homes located adjacent to one another. Each home had a different classification, but all residents needed to communicate with the OOA (Onsite Overnight Assistance) worker located in a central base.

The homes included:

  • House 1: High Physical Support (HPS)

  • House 2: Fully Accessible (FA)

  • House 3: Improved Liveability (IL) + OOA support worker office

  • House 4: Fully Accessible (FA)

A major design requirement was that House 1 contained the NDIS-mandated battery backup (UPS). However, the staff monitoring station was in House 3. This required careful engineering so the Intercom Solution NDIS would remain fully operational even if Houses 2, 3, or 4 lost their mains power.

We needed to achieve the following:

  • Full intercom connectivity between all homes

  • Ability for any resident to call the OOA support worker

  • Centralised monitoring at House 3

  • Long-range cabling between dwellings

  • Cloud-based system management

  • Integration with emergency pendants and assistive devices

  • Reliable operation during a blackout

Our solution used a combination of Akuvox intercom technology, long-range 2-wire cabling, cloud-connected SIP calling, and a centrally located UPS.

Why Akuvox Was Selected for This Intercom Solution NDIS

The 2-wire version of Akuvox supports distances up to 300 metres, making it ideal for SDA homes located on large blocks or across multiple lots.

2. Cloud-based management

Through Akuvox Cloud, SIL providers or property managers can remotely:

  • Monitor device status

  • Change call routing

  • Update firmware

  • Review call logs

  • Expand or modify the system

This makes the Intercom Solution NDIS scalable and future-proof.

3. Multiple device types

Akuvox supports:

  • Indoor monitors

  • Video door stations

  • Wearable pendants

  • IP phones

  • Assistive switch inputs

  • Network sensors

This allows the Intercom Solution NDIS to be customised for different SDA classifications.

4. Highly reliable SIP communication

Calls between homes use SIP protocols, which are stable, fast, and compatible with cloud routing.

5. Assistive technology integration

NDIS homes often require integration with:

  • Pull cords

  • Fall detection sensors

  • Door contacts

  • Smoke detectors

  • Push buttons

  • Smart relays

Akuvox supports these integrations natively.

For SDA developers planning large or multi-site projects, this makes the solution extremely adaptable.

Cabling and Network Topology Used in This Intercom Solution NDIS

A critical part of designing a multi-home intercom system is selecting the right cabling architecture. We used a 2-wire long-range configuration because the distance between houses exceeded 100 metres in some areas.

Key network design elements included:

  • A long-range NS-2 network switch placed in House 1

  • All homes linked through underground conduit using 2-wire cabling

  • NC-2 converters where PoE-only devices required adaptation

  • SIP routing configured through the cloud

  • A 4G/5G modem or NBN connection with UPS backup

  • Automatic call sequences (fallback routing to mobile phones if unanswered)

This design ensured that the Intercom Solution NDIS remained robust, even if one home experienced an outage or disconnection.

How the Central UPS Maintains NDIS-Required Resilience

NDIS requires critical communication systems to remain operational during a blackout. For this reason, the UPS installed in House 1 needed to support:

  • NBN or 4G/5G modem

  • Router

  • NS-2 intercom network switch

  • Any SIP gateway

  • Cloud connectivity

A high-quality UPS such as the PowerShield Commander 2kVA was recommended:
