Socket Plus (type G): Automation plus fire safety

Ajax Systems announced an addition to the automation product line — the new Socket Plus (type G) — a smart socket with a British plug and a unique mechanism against arc faults. Socket helps Ajax users remotely control appliances’ power supply, monitor their power consumption, and protect them against overcurrent and voltage surges. As a part of an Ajax system, Socket Plus (type G) executes automation scenarios, making life safer and more comfortable.

Each year, around 20,000 fires in the UK are caused by electricity. Due to faulty devices, damaged wires and uneven load. So to keep you safe from this, we’ve improved one of our most popular devices.

The first barrier against arc fault

An arc fault is a spark phenomenon between two conductors with high current density and low voltage. In simple words, this is a rapid temperature spike in damaged wires or contacts of an electrical appliance. It can also occur in place of an improper connection with an outlet or inside the device itself.

In some modern buildings, arc fault prevention devices are already installed in junction boxes. They automatically switch off an entire section when abnormal current flow is detected. But such an approach makes it difficult to determine the exact faulty device. Plus, it requires the involvement of a professional electrician to restore regular operation. In turn, even a minor problem costs money and time.

Socket Plus (type G) helps to localize a faulty device, eliminating the risk of ignition. No need to wait hours, or even days, for an electrician, all other sockets and appliances continue to operate normally.

How it works

Suppose damaged electronics or a wire with damaged insulation is connected to the Socket Plus (type G). In that case, a unique patented module will detect abnormal current flow in the circuit that precedes arcing and shuts off the power. At the same time, the LED frame on the socket will change colour to red, and the system will send a notification to all users.

Socket Plus (type G) received a protection mechanism against arc faults, a unique solution among smart sockets.

Once the faulty device is turned off, it is enough to tap a toggle in the Ajax app or press the physical button on the socket on-site to restore its regular operation.

Security software serving users’ comfort

Socket Plus (type G) can be connected and set up in minutes. Adding the new socket to the system includes three simple steps: scanning a QR code with the Ajax app, naming the socket and assigning a room. The Jeweller radio protocol ensures uninterrupted interaction of all the system devices. It uses frames to synchronize device communication, authentication to prevent forgery, and encryption to protect against hacking. Thanks to Jeweller, Socket Plus (type G) can be installed at a distance of up to 1,100 meters from an Ajax hub. And even twice as far with a range extender.

Socket Plus (type G) is effortlessly set up and controlled in the Ajax app.

Ajax apps help control and set up the socket from anywhere in the world via the Internet. There is a real-time device status and power consumption meter. Everything is set up in a few clicks — starting with the brightness of the LED and ending with automation scenarios. With other Ajax devices, it is easy to create scenarios based on temperature, CO2 or humidity rise. A few taps in the Ajax app allow you to set up a schedule, synchronize the socket with security or even lighting.

The best components and reliable communication using the Jeweller radio protocol, which does not depend on Wi-Fi, guarantee that the socket will do the job. Regardless of how many sockets are in the system.


Socket Plus (type G) will be available for order in the fourth quarter of 2022.
