Alarm Systems for Older People – How to Choose the Right One with Ajax Systems and Outdoor Detection

November 25, 2025 5 min read

In this article we focus on how to set up an alarm system that's specifically suited to older people: easy to use, reliable and quick to summon help. We look at the excellent range from Ajax Systems as well as the more traditional but highly effective outdoor detectors: the UMA AIR‑B60‑2 dual beam detector set and the UMA AIR‑BI1001408 multi beam detector set. You can use these, for example, to detect someone walking through the garden and send an alert to a security guard or family member.

1. Why an alarm system designed for older people?

Older people often have different needs from younger users:
✔ Simple operation – ideally a single press of a button.
✔ Instant alerts to family, informal carers or care providers.
✔ Reliability: keeps working during a power cut, with no complicated controls or devices.
✔ Options such as fall detection, a panic button or outdoor motion detection to improve safety around the home.

A suitable alarm system for older people doesn't just protect against burglary – it also helps when assistance is needed quickly, for example after a fall or when something unexpected happens.

2. Why choose Ajax Systems?

Ajax Systems is a security system whose strengths match the needs of older people closely:

Modern wireless systems that are easy to install and operate.
Support for panic buttons (such as the Ajax Button) to call for help immediately.
The platform sends notifications to your smartphone – ideal for family members or care partners who live further away.
Expandable: you can add and link extra sensors, motion detectors or outdoor detection (such as the WL4 sets) later on.
Reliable connectivity – many devices use secure wireless protocols (such as Jeweller) and are well supported.

In short: a system that suits older people because it's user-friendly, reliable and expandable.

3. Integrating outdoor detection: WL4 AIR detectors

Besides standard indoor protection, you can also improve safety outdoors – think of the garden, driveway or a path around the house. The two detector sets mentioned above are ideal for this:

WL4 AIR‑B60‑2 dual beam detector set: an active infrared dual-beam detector for outdoor use, with a range of up to approx. 60 m.
WL4 AIR‑BI1001408 multi beam detector set: a multi-beam option with an outdoor range of up to approx. 100 m.

According to the product page, these detector sets can be connected externally to an alarm system (for example via a "DoorProtect" input), so you receive an alert whenever someone walks through the garden.

Benefits of outdoor detection for elderly security

✔ Helps prevent someone from falling outside the home or wandering outdoors unintentionally – for example at night or with reduced mobility.
✔ Extra peace of mind for family members or carers: movement outside is monitored too.
✔ Linking it to the indoor alarm system means one central system, with no separate installations.

Points to consider

Make sure the detector is positioned correctly (height, clear beam path, no unwanted triggers from animals, wind or traffic).
Think about weather resistance: outdoor installation calls for a suitable housing, maintenance and possibly a power supply.
Connect the detector correctly to the alarm system or control panel so that alerts are reliable.

4. Setting up an elderly-friendly alarm system in practice

Step 1: Basic Ajax installation

Choose an Ajax hub (e.g. Hub 2 4G) so the system stays connected even if the internet goes down.
Install a panic button (Ajax Button) within easy reach: bedside table, living room chair, bathroom.
Optionally add a remote control or key tag for easy arming and disarming.

Step 2: Add indoor detection

Motion detectors (PIR) in the living room, hall, corridor and other key rooms.
Opening sensors (door/window) on the main entry points.
Make sure alerts are clear: for example a siren plus a notification on a smartphone or to a contact person.

Step 3: Add outdoor detection

Mount the WL4 AIR detector set in the garden or across a passageway.
Connect it to your Ajax system via a DoorProtect.
Configure the alert: when the outdoor sensor is triggered, an alarm notification is sent to the app or care contact.
Make sure the system can also be easily disarmed by the older person, or switches to standby automatically (e.g. offline or in a low-sensitivity mode at night).

Step 4: Ease of use & training

Help the older person get comfortable with the panic button: practise using it together once.
Draw up a list of who will be linked as emergency contacts: family, neighbours, informal carers.
Configure app notifications so you know straight away what's going on – but avoid notification overload.

Step 5: Maintenance and testing

Check the batteries of wireless components regularly. Most Ajax products last around 4 years.
Test the outdoor detector periodically (e.g. a monthly walk test).
Make sure people know how the installation works: who can step in if there's an alarm or a false alert?

5. Why this combination works for older people

Ajax Systems offers simple operation and fast assistance: panic button, app notifications and reliable hardware.
The UMA AIR sets add a layer of outdoor protection, providing extra safety when someone is still walking outside in the evening, for example, or when there's unfamiliar movement around the house.
Together they form an integrated system that works both indoors (fall detection, panic button, alarm sensors) and outdoors (motion detection, perimeter protection) – ideal for seniors who want both protection and independence.

6. Summary & recommendation

For older people, an alarm system isn't just about preventing burglary – above all, it's a tool for safety and independence.
Choose a system that is user-friendly, quick to access (with a panic button) and reliable – such as Ajax Systems. Optionally combine it with outdoor detection such as the dual or multi-beam WL4 AIR detectors for extra protection around the house.
