Airis Stove Guard: Frequently Asked Questions

A stove guard, sometimes called a cooker cut off device, comprises of a sensor and a controller. In the event of a dangerous situation, the sensor will instruct the controller to disconnect the power to the hob/stove.

However, not all devices marketed as a stove guard provide the ideal level of protection. Airis is by far the most advanced in this area. More information can be found at stoveguard.co.uk.

Extremely, in terms of both fire prevention and product quality. Since early 2018, we have supplied many customers – both private individuals and large organisations. Our business customers all have several hundred Airis systems each, and we are pleased to say that not a single customer has ever had to return more than one unit, if any!

Airis is designed to work for a minimum of 15 years and is made in a factory that specialises in high build quality. This encompasses automated state-of-the-art quality testing of the production processes, integrated with quality management. Unicook has visited the factory and inspected the end-to-end process first-hand. Each Multisensor and PCU assembly is electronically examined at many stages, culminating in a test at maximum load.

If you are an organisation looking at installing Airis and would like to talk to one of our existing customers, please let us know and we’ll be pleased to arrange contact. If you are an individual looking into Airis for your home or a loved one, we have many reviews from happy Airis users.

Cutting the power at a specific temperature is comparatively easy to achieve but it can result in false alarms or a lot of smoke, depending on the level set. Using simple analysis of infrared doesn’t take account of the fact that each pan radiates heat differently depending on the colour of the pan. For example, a stainless steel pan will radiate differently to a pan coated in black Teflon. Airis uses a patented technique which analyses three wavelengths. In this way it can far more accurately assess the real temperature. Airis combines this with algorithms, built using artificial intelligence, which ‘understand’ the effect of steam and particulates on infrared radiation. This makes Airis uniquely able to avoid false alarms as well as cut the power early enough to minimise smoke.

No, 80 percent of fires start within the first 15 minutes of cooking – sometimes even less than two minutes. There is little value in restricting cooking time and it can be frustrating for the person cooking.

Airis Sense Wi-Fi does not require a Wi-Fi connection to shut off the cooker and prevent fires and smoke – the Wi-Fi connection is required only for sending notifications to relatives or carers, or for connecting with Airis Cloud for additional wellbeing support. Airis and Airis-C do not have Wi-Fi capability.

Norway was the first country to make EN 50615 technology mandatory in 2015 for all domestic kitchens. Other countries are considering this option.

After Airis cuts the power, it beeps and flashes periodically. Resetting is easily done by pressing the OK button in the centre of the sensor - the power will be switched back on immediately.

Yes, BS EN 50615 devices were included in the building regulations update BS 9991:2024. Feel free to contact us for more details or to arrange a CPD presentation.

So far, six UK fire and rescue services install Airis in the homes of vulnerable people.

Smoke detectors are not installed in kitchens because they create false alarms. When a smoke detector goes off, for example when installed outside the kitchen, it may be too late to evacuate, especially for vulnerable people.

A heat sensor doesn’t prevent a fire. A fire has to start and raise the air temperature before the heat sensor raises the alarm and valuable time is lost. With Airis, there’s no fire and far less smoke.

Yes, Airis is often used to mitigate risk in building designs where escape routes could be compromised by the location of cooking facilities.

Airis is a proactive safety device. It prevents fires and, in many cases, smoke. That means a significantly lower chance of sprinkler system activation and the subsequent and widespread water damage.

Sprinkler systems only activate nine out of ten times. Airis activates successfully in 99% of cases.

Airis can therefore be a low-cost complement to a property already equipped with a sprinkler system.

The Airis Sense and Airis Sense Wi-Fi Multisensors attach to the wall behind the hob or cooker, or to the cooker hood. The Airis-C Multisensor is for ceiling mounting in situations where the hob is installed in an island or where there’s no suitable position for the standard Airis Multisensor. Airis Sense Wi-Fi features Wi-Fi capability (and therefore the potential to use Airis Cloud) – Airis Sense and Airis-C do not. However, all Airis variants provide identical, high levels of safety against fire and smoke.

No. This functionality is only available with Airis Sense Wi-Fi.

Yes! In the UK, the Safera Sense (WiFi) is called Airis Sense Wi-Fi. We also supply Airis, as well as Aurora (known in the UK as Airis-C). Please contact us if you need any clarification or to discuss your requirements.

Cooking will be prevented. Airis precisely records its position during installation and knows when it has been moved.

Yes, suppression hoods don’t prevent fire or smoke. Airis does.

Yes, most of the images on our website are of Airis Sense Wi-Fi, but we still sell Airis Sense and Airis-C. Please contact us to confirm your requirements.

Heat sensors, smoke sensors and sprinkler systems don’t prevent smoke. Airis greatly reduces smoke and prevents fires. Residents in studio apartments are more vulnerable to the dangers of smoke and fire from the kitchen.

People over 80 are twice as likely to have a cooking fire. Airis helps elderly people stay independent and gives peace of mind to them and those that care for them. Airis can be connected to telecare if required.

Yes and no.

Induction hobs help protect the kitchen user from burns, as the cooktop doesn’t reach as high a temperature as other types of hob. However, with an induction hob a fire is possible in a much shorter time duration. Watch our video showing just how quickly this can happen. Equipping an induction hob with Airis can ensure the benefits can be enjoyed without bringing other risks into the kitchen.

Yes. Cooking is the most common cause of house fires and cooktop fires are set to become a bigger risk in the future, for some key reasons:

• Around 1 million people have dementia in the UK and this number is set to rise to 2 million by 2050
• Induction hobs are highly efficient and are now inexpensive and popular, but a fire can occur much more quickly with an induction hob
• The population is aging and a person over eighty is twice as likely to have a cooking fire
• Gas is likely to be phased out for sustainability reasons. Cooking fires are twice as likely on electric hobs than on gas.

A vinyl sticker is provided in the box. This is useful when the occupants might change periodically, such as in student accommodation. It can also serve as a reminder for people with dementia.

Airis products can be installed in most circumstances without needing any settings to be changed. Only the PCU requires wiring. The Multisensor is wireless and is very securely attached with VHB tape (already attached) to most surfaces. The installation verification process takes 5 seconds. Airis products take under an hour to install. If settings do need to be changed, the manual explains how this can be quickly done. With Airis Sense Wi-Fi, a mobile app can also be used to make this part of the process even more straightforward.

When installing several units in the same building, an electrician – once familiar with the process – can install Airis at a rate of at least 10 units per day.

If you're an electrician looking to get an overview of the installation please visit our Knowledge Base for installation guides, datasheets, and product manuals.

The PCU is wired between the wall power outlet and the hob/cooker. It’s usually mounted behind a built-in oven, on the wall behind the free-standing cooker or, if space is limited, under an adjacent kitchen cabinet plinth.

The Airis and Airis Wi-Fi Multisensors are mounted on the wall/splashback behind the cooker/hob or on the cooker hood, with VHB tape for a very secure fixing on ceramics, metal and glass without the need for drilling.

The Airis-C Multisensor is mounted on the ceiling with screws.

The set up (verification) process takes a matter of seconds. Only a small number of tools need to be carried for the job.

Airis comes with an unlimited warranty for as long as your subscription runs. A one-off purchase comes with a 2-year manufacturer’s warranty, which Unicook extends to 3 years when you register your product. Please refer to the Knowledge Base for further details.

The Airis PCU is available in ratings 35A or 50A.

No, the radio pairing between the PCU and Multisensor is unique.

Yes. If the two cookers/hobs are less than 150mm apart, the Multisensors must be offset. Please contact us for instructions.

Airis devices do not require any maintenance. A simple user test is provided and the manufacturer recommends that this is carried out periodically. Please refer to the user and installation manuals in the Knowledge Base. The Multisensor should be wiped clean occasionally to prevent a build-up of grease.

The batteries last from 3 to 7 years, depending on the model used. When the battery is low, an LED flashes on the Multisensor and sounds a beep. If Airis Sense Wi-Fi is used, a notification will be sent to relatives/carers/personnel.  All Airis Multisensors use replaceable AA batteries.

Both the Multisensor and PCU have extensive self-diagnosis and on-board data recording, which has enabled the product to be made highly reliable. Should a fault be found in either the Multisensor or the PCU, cooking is limited to a short period, after which the user must reset the power with the OK button to continue.

If a problem has been detected and the OK button is pressed, a series of colour flashes indicates the precise nature of the issue.

All Airis products have a volt-free output (normally open) which can be connected to any telecare system. Please contact us for further advice. Wi-Fi is not required for connecting an Airis device to telecare.

Airis is only for electric hobs (all types).

Yes. Airis works with all hobs/stoves powered by electricity, including induction, ceramic/halogen, and older 'iron ring' style hobs.

For this application, a ceiling-mounted version of Airis is available called the Airis-C. Note that this model doesn't have Wi-Fi capability.

Yes, but ALL versions of Airis prevent fire and most smoke.

Airis Sense is mounted on the wall, but does not have Wi-Fi or remote alert functionality.

Airis Sense Wi-Fi does everything that Airis Sense does, except it has Wi-Fi which enables it to send SMS and email alerts to relatives, carers, or personnel, depending on the application.

Airis-C is mounted on the ceiling. It does not have Wi-Fi or remote alert functionality.

Airis is ideal for people living with neurodegenerative disease, including Alzheimer's. This is why no button presses or actions by the user are necessary in order to use the stove. The individual cooks on the hob in the way that they always have done, as he or she wishes, protected by Airis in case of a dangerous situation.

Your order should arrive in 7 working days or less.
