Ajax is known mainly for wireless alarms run from a central hub and a well-designed app. It's a good match for apartments, renovated homes you don't want to cut into, and people who like managing things from their phone.
Ring 0421 772 661 to plan your system. A floor plan, even a hand sketch, lets us suggest a sensible detector layout.
An Ajax system looks quite different from a traditional alarm. Instead of a metal panel box in a cupboard, there's a compact hub, and the detectors, door contacts, keypads and sirens connect to it wirelessly. Setup, arming and notifications all happen through the Ajax app.
Because there's little or no cabling to detectors, Ajax suits finished interiors: freshly painted terraces, apartments with concrete ceilings and homes where the roof space is inaccessible. The trade-off is battery-powered devices, which need replacing every so often, and a hub that needs good placement for coverage.
Blue Link Electrical is a licensed electrician based in Hurlstone Park, holding NSW Security Licence S00014414 and Electrical Contractor Licence 332956C. We plan, install and commission Ajax systems across the Inner West and Sydney.
Ajax hubs come in versions with different communication options, such as Ethernet, mobile and Wi-Fi, and different device capacities. For reliability, a hub with more than one way to reach the internet is worth considering, so notifications still get through if your broadband drops. Check each hub's specifications against the number of devices you plan to use.
Ajax also offers wired-device options for installers who want them, but most homes choose the wireless range. Whatever you buy, the location of the hub matters most: central, out of sight, away from large metal objects and close to a power point and network connection.
The hub plugs into mains power and has a built-in backup battery for outages. A power point in the right central spot may need adding.
An Ethernet connection to the hub is more dependable than Wi-Fi. We can run a data cable if there isn't one; see Ethernet cabling.
Large or multi-level houses with thick brick walls may need a range extender. We test signal at each device location before fixing.
Detectors, contacts and sirens run on batteries. The app warns you as they get low.
Optional, but handy for family members who don't want to use the app every time.
Apartment by-laws may limit external sirens or drilling. An indoor siren is often a sensible alternative.
1. Plan the coverage. We mark detector positions, decide whether you need a range extender, and choose a hub location with power and a network connection. You get a written quote.
2. Power and data. If needed, we add a power point or data point at the hub location, so it isn't relying on a power board behind the TV.
3. Mount and pair. Devices are paired with the hub, signal-tested in place, then fixed. Detectors are aimed to avoid heaters, windows and pets.
4. Configure and hand over. We set up groups, night mode, users and notifications in the app, test every device and the siren, and show you around the app. Our alarm guide covers the broader choices.
Usually Wi-Fi at the edge of range or a router change. A cabled connection or mobile backup is the fix.
Thick walls, new mirrors or metal shelving can weaken signal. Moving the device or adding a range extender helps.
The power point or circuit feeding the hub has lost power. Check the switchboard; see alarm panel no power.
Often phone settings or app permissions rather than the system itself. We check both sides.
Ajax is designed to be straightforward, but NSW treats alarm installation for others as licensed security work, and good placement makes a big difference. We hold Security Licence S00014414.
Yes, it's a common choice because it needs little drilling. Check your strata by-laws about external sirens.
The hub switches to its backup battery and devices keep running on their own batteries. How long it lasts depends on the hub and how it's connected.
No. Ajax can send notifications to your phone, and monitoring companies offer professional monitoring as a separate service.
