Below is a guide on the most common personal alarm types, dimensions, features and materials to help you make the best choice for your situation.

Pendant Personal Alarm Sizes & Features

The pendant remains the most popular style of old age personal alarm in Australia, and for good reason. It sits comfortably around the neck and is easy to activate with one press, even for people with limited hand strength or arthritis. Most pendants are small and lightweight, so they do not feel burdensome during daily activities like gardening, cooking, or walking around the home. Pendant alarms work just as well outdoors in the backyard as they do indoors, making them a versatile choice for Australian lifestyles.

• Typical pendant dimensions: approximately 6.2 cm x 4.7 cm x 1.7 cm (W x H x D)
• Typical weight: 25 g to 53 g depending on the model
• Wear options: lanyard around neck, wristband, belt clip, or pouch
• Water resistance: IP67 rated (submersible to 1 metre for 30 minutes) on most 4G models
• Battery life: typically 5 to 7 days on a full charge
• Connectivity: 4G mobile network, no landline or NBN required on modern models

Smartwatch Personal Alarm Sizes & Features

A smartwatch-style personal alarm for elderly users is a great option for those who are more active and prefer something that looks less like a medical device. These are worn on the wrist like a regular watch and are increasingly popular among seniors who go out regularly, whether it is a morning walk, visits to the local shops, or catching up with friends. The wrist form factor also means it is harder to accidentally leave behind.

• Typical screen size: 1.4 cm to 1.6 cm display
• Battery capacity: 850 mAh to 1000 mAh, typically lasting 5 to 7 days
• Charging method: magnetic charging cradle, full charge in approximately 2 hours
• SIM card type: Nano SIM (4G), not included with most models
• Water resistance: IP67 or IPX7 waterproof rating on quality models
• Materials: ABS and polycarbonate casing, silicone strap
• Positioning: GPS, WiFi and LBS combined for indoor and outdoor tracking

In-Home Base Unit Personal Alarm Sizes & Features

The traditional in-home system is designed for people who primarily need coverage inside their home and immediate surrounds. The base unit sits on a benchtop or shelf and connects to your home via NBN or WiFi. A wireless pendant with a range of up to 100 metres is included. This type of personal alarm is a reliable and cost-effective option for elderly Australians who mostly stay at home or live in aged care villages.

• Base unit dimensions: approximately 18 cm x 5.8 cm x 9.8 cm (L x W x H)
• Pendant range: up to 100 metres from the base unit
• Pendant weight: typically under 30 g
• Connectivity: landline, NBN, or WiFi depending on the model
• Best for: indoor use at home or in a retirement village

Mobile GPS Personal Alarm Sizes & Features

A mobile GPS personal alarm is ideal for people who are still out and about regularly. These devices work anywhere there is a 4G mobile signal across Australia, which means they are just as useful at the park or the shops as they are at home. Many can be worn as a pendant or a wristband, giving flexibility for different situations throughout the day.

• Weight: typically 40 g to 80 g
• GPS accuracy: location sent to emergency contacts via Google Maps link, accurate to approximately 2 metres
• Network coverage: Telstra 4G network covering 99% of populated Australia
• SIM requirement: a standard Nano SIM card on a low-cost prepaid plan
• Contacts supported: up to 3 to 6 emergency contacts depending on the model

Additional Personal Alarm Considerations

1. Fall Detection vs Manual SOS: Fall detection uses built-in accelerometers to automatically trigger an alert if the device detects a sudden drop followed by no movement. It is a major safety advantage for people who live alone and may be unable to press a button after a fall, but it should be treated as an extra layer of protection rather than a replacement for the SOS button.
2. Monitored vs Unmonitored: A monitored alarm connects to a 24/7 professional response centre. Unmonitored alarms dial a list of family or friends directly. Monitored services generally cost more, but they can offer a meaningful safety net for people who live alone.
3. Waterproofing is Non-Negotiable: A significant number of falls among older Australians happen in the bathroom. A device rated below IP67 should not be considered for most users.
4. SIM Card and Network Costs: Most 4G mobile alarms require a SIM card that is not always included. Check whether a SIM is provided and what the ongoing plan cost is before purchasing.
5. Government Funding Eligibility: Many Australians may be eligible for subsidised or fully funded personal alarms through My Aged Care, the NDIS, or state-based programs.

Common Personal Alarm Materials

Understanding what a personal alarm is made of helps you assess comfort, durability and suitability for everyday wear. Most devices are worn for many hours each day, so the materials genuinely matter.

ABS and Polycarbonate Plastic Casing

The most common casing material for both pendant and watch-style alarms. It is lightweight, durable, and easy to mould into compact shapes. The hard plastic protects internal components from impact and moisture.

Pros:

• Lightweight, often under 60 g
• Impact resistant for everyday knocks and drops
• Allows waterproofing seals to be effective

Cons:

• Can look and feel clinical or medical in appearance
• May feel warm in hot Australian summers when worn directly on skin

Silicone Strap

Most wristband and watch-style personal alarms use silicone straps. Silicone is flexible, skin-friendly, and easy to clean.

Pros:

• Comfortable and non-irritating on sensitive skin
• Waterproof and easy to wipe clean
• Available in multiple colours

Cons:

• Can attract lint and dirt over time
• May feel tight for users with larger or swollen wrists

Lanyard and Fabric Cord

Pendant-style alarms are typically supplied with a breakaway lanyard made from fabric or nylon cord. A breakaway clasp is an important safety feature, as it releases under pressure to prevent the lanyard from becoming a strangulation risk.

Pros:

• Keeps the alarm visible and easy to locate
• No wrist sizing issues
• Breakaway design adds an important safety element

Cons:

• Can become tangled if worn constantly
• Some users forget or dislike wearing items around their neck

Top 6 Tips for How to Choose the Right Personal Alarm

1. Think about where they spend most of their time. Someone who rarely leaves home may only need an in-home base unit, while an active user is better suited to a mobile GPS model.
2. Prioritise wearability above all else. The most common reason personal alarms end up unused is that the person did not want to wear them.
3. Check the waterproof rating before buying. Only consider devices rated IP67 or above for reliable bathroom use.
4. Understand what happens when the alarm goes off. Know whether the device calls family directly or connects to a monitoring centre.
5. Consider fall detection as an add-on, not a replacement. It is useful, but it is not infallible.
6. Check government funding options first. Before paying out of pocket, review whether the user may qualify for support through My Aged Care or the NDIS.
