Everything ships fully configured — our office pre-programs the SIM and your contact details before the unit ever reaches you, so there's genuinely very little to do at home. Sit the base unit within a couple of metres of a power point, plug it in, and switch on the battery backup underneath the unit. That's it — because this system runs entirely over the 4G mobile network, there's no landline, NBN connection, ethernet cable or WiFi setup required at all.

The pendant and any wall buttons talk to the base unit over a shorter-range wireless link — typically 100 to 300 metres in open air, though thick walls, distance and interference will reduce this in practice. It's a property-based system, so it covers the home and yard well but won't work once you've left the property, at the shops for example.

If you're in an area with weaker mobile coverage, see Checking Signal Strength & Antenna Range below.

Pressing the pendant, a wall button, or the HELP button on the base unit itself sends a signal straight to the base unit. The base unit will then notify the monitoring team, the monitoring team can then speak through the base unit and arrange care.

The stand-out feature here is Voice-Back — once your call is answered, the base unit automatically opens hands-free two-way voice, so there's nothing further to press or hold even if you're on the floor and can't reach the unit. See the next section for more on how this works.

The MediGuardian suits residential homes, retirement villages, and hospital settings where someone on site can respond once the alert comes through — whether that's a family member, an on-site carer, or our monitoring team.

Voice-Back is what separates a genuinely monitored alarm from a basic dialler. Ordinarily, answering an incoming call means finding a phone and pressing a button — not exactly realistic if you've just had a fall.

With Voice-Back, the base unit answers the return call itself, hands-free, the moment your contact or our monitoring team calls back. You'll hear them straight away and can talk normally from wherever you are in the room — no button to find, no phone to pick up, and no risk of the call going unanswered because you couldn't reach it in time.

• Connectivity — 4G mobile network, SIM pre-installed & pre-configured — no landline, NBN or WiFi required
• Base unit — L210 x W130 x D35mm, approximately 590g including battery
• Backup battery — rechargeable, provides 40+ hours of runtime during a power outage
• Pendant / wall button range — typically 100–300m open air from the base unit
• Pendant waterproofing — IP67 rated, safe in the shower (avoid full submersion in the bath)
• Comes fully programmed — configured in our office before dispatch
• Backlit Help & Cancel buttons — easy to see and use in low light
• Interchangeable wear — worn on the wrist or around the neck using the included holders

Because the base unit relies on the 4G network, signal strength matters. Press the green Cancel button while the unit is idle and it displays a signal reading from 0–9 for a couple of seconds:

• 0–1 — weak signal
• 2–5 — average signal
• 6–9 — strong signal

For the best reception, position the base unit somewhere with a clear view outside — near a window is usually ideal — and away from large metal objects, microwaves and WiFi routers, which can all interfere with the signal.

In a weak-coverage area, an external antenna is available. It plugs straight into the antenna port on the back of the unit and is placed and tested before it's stuck down permanently, so reception is confirmed first.

Additional waterproof wall buttons can be installed anywhere extra coverage is useful around the property.

Each additional standard pendant includes both a lanyard and a wristband, so the wearer can choose how to carry it. If a fall risk is a concern, you can also upgrade to a pendant with built-in fall detection, which can trigger an alert automatically even if the button itself isn't pressed.

A keysafe lets responders access the property without forcing entry. Provide a 4-digit code and we'll program it into both the alarm and the keysafe itself.

The system runs over the 4G mobile network rather than your home internet. 24/7 professional monitoring is $30 per month on the online direct debit price (or $45 per month by monthly invoice) — see 24/7 Professional Monitoring below for what's included.

If you'd rather not pay for the hardware upfront, a rental path is also available. It bundles the system rental together with monitoring into a single monthly fee, rather than paying for the unit outright plus a separate ongoing cost.

The unit remains our property under this option and needs to be returned if the service is ever cancelled.

This system is professionally monitored only — every alert is routed straight to our Australian, ASIAL-approved monitoring centre, not to family members or a private contact list. It's $30 per month on the online direct debit price (or $45 per month if paying by monthly invoice), with no lock-in contracts and the ability to cancel anytime.

• Wear the pendant at all times — it only works if it's on you when you need it
• Test your pendant and base unit monthly with our monitoring team, just to confirm everything's working
• Keep the base unit connected to power at all times, and avoid moving it once it's installed and signal-tested
• Wipe the base unit and pendant clean with a soft, slightly damp cloth if needed — never submerge the base unit
