Airis – Frequently Asked Questions

If you don’t find an answer to your question below, please get in touch via the Contact page.

How reliable is Airis?

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 reviews on Amazon from happy Airis users.

At what temperature does Airis cut the power to the hob?

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.

Does Airis limit cooking time?

No, 80 percent of fires start within the first 15 minutes of cooking – even less than two minutes. There is little value in restricting cooking time.

Do I have to connect Airis Sense WiFi to WiFi?

Airis Sense WiFi does not require a WiFi connection to shut off the cooker and prevent fires and smoke – the WiFi 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 WiFi capability.

Why isn’t Airis mandatory?

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

Does the fire service recommend Airis?

So far, 6 UK fire and rescue services install Airis in the homes of vulnerable people.

I have a smoke alarm, so why do I need Airis?

Smoke alarms aren’t fitted in kitchens because they create false alarms. When a smoke alarm eventually activates, for example when fitted outside the kitchen, it may be too late to evacuate, especially for vulnerable people.

Do I still need Airis if I have a heat sensor in my kitchen?

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.

Do building control departments recognise Airis?

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

Do I need Airis if I have a sprinkler system?

Yes. Airis will prevent a sprinkler system activating, meaning no water or smoke damage. Airis acts to prevent a fire as well as significant smoke, whereas a sprinkler system is only activated after a fire has started.

What’s the difference between Airis, Airis-C and Airis Sense WiFi?

The Airis and Airis Sense WiFi 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 WiFi features WiFi capability (and therefore the potential to use Airis Cloud) – Airis and Airis-C do not. However, all Airis variants provide identical, high levels of safety against fire and smoke.

Do Airis or Airis-C have WiFi?

No. This functionality is only available with Airis Sense WiFi.

What about the Safera Sense/I can’t find the Safera Sense, do you sell it?

Yes! In the UK, the Safera Sense (WiFi) is called Airis Sense WiFi. 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.

What happens if the Multisensor is removed from the wall or repositioned?

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

Do I need Airis if I have a suppression hood?

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

I was quoted for Airis prior to 2021, but the product looks like it has changed. What’s different, and can I still buy the product I was quoted for?

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

Why is Airis especially important for studio apartments?

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.

Why is Airis especially important for elderly people?

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.

Are induction hobs safer?

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.

Are cooking fires still a significant risk?

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.

Is there a sign or sticker available for the kitchen to tell the user how to reset the power?

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. Click here to see the sticker.

How is the power reset after Airis prevents fire or smoke?

After Airis cuts the power, it beeps and flashes periodically. Resetting is easily done by pressing the OK button.

How long does it take to install Airis, Airis-C or Airis Sense WiFi?

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 WiFi, a mobile app can also be used to make this part of the process even more straightforward.

How long does it take to install several Airis, Airis-C or Airis Sense WiFi units?

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.

What is the installation process?

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 Sense WiFi 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.

What is the warranty?

All Airis products come with a 2-year manufacturer’s warranty. Please refer to the user manual on our Downloads page for further details.

What is the rating of the PCU?

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

Can one Airis interfere with the radio signal of another in the same building or kitchen?

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

Can two Airis’ be used in the same kitchen?

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

What maintenance is required?

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 relevant guide in the downloads section. The Multisensor should be wiped clean occasionally to prevent a build-up of grease.

What is the battery life?

The battery life is 18 months.. When the battery is low, an LED flashes on the Multisensor and sounds a beep. Both the Airis and the Airis-C Multisensors use AA batteries.

What happens if an Airis device fails?

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.

How does Airis connect to telecare?

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

Can I use Airis for gas cookers?

No. If fitting an Airis is the only way to ensure a vulnerable person can cook safely, we suggest changing the gas hob to halogen with rotary mechanical controls.

Does Airis work with all types of electric hobs/cookers?

Yes.
