Cuts the power if the Multisensor detects danger

Temperature analysis
The Multisensor monitors surface temperature using patented IR analysis, cooking fumes (smoke and steam), humidity and air temperature with AI developed algorithms. Both the cooking temperature and the ambient temperature of the room are monitored. The temperature and rises in temperature are taken into account, as well as the type of stove – halogen, metal plate, or induction, for example.
Fail-safe communication
Airis Sense uses a high power two-way digital communication between the Multisensor and the power controller with a bespoke protocol developed by Safera called RobustLink. A digital signal is also far more reliable than an analogue radio signal. Frequently, analogue radio frequencies can be prone to interference from non-critical applications, such as garage-door remote controls. Without bi-directional communication, the PCU cannot know if the sensor is working correctly, or even at all. If the Airis sensor ever fails, cooking will be prevented to ensure the safety of the resident.
Fail-safe Multisensor orientation
The Multisensor has a firmly fixed attachment. For additional security, during installation the Multisensor measures its own pitch and roll axis to ensure that it has been placed horizontally. If the Multisensor is incorrectly mounted, or is moved from its original position any time thereafter, the power controller will prevent cooking to ensure the safety of the resident. A security cover is available to prevent removal of the Multisensor. We generally supply and recommend these for student accommodation applications, and sometimes in assisted living schemes.
Power monitoring
The role of the PCU is not just to cut the power when required; it also monitors the power consumption and makes this information available to the Multisensor. This enables the Multisensor to know when to analyse its own data, approximately every second. The PCU is able to determine the type of stove by analysing the current flow. The Multisensor includes this in its analysis. The PCU has volt-free outputs for connection to other systems such as BMS or telecare, and also has an input for the connection of leak sensors.
Smoke and steam analysis
The Multisensor monitors the amplitude of the infrared readings. In this way, it is able to tell if the readings are being affected by steam or smoke. Using its AI algorithms, built by machine learning, Airis can often determine when food is starting to burn and when a pan has boiled dry.
Human presence monitoring
The Multisensor detects when someone is close to the hob. The algorithms take this into account when deciding if the power should be disconnected. If someone is present (very close to the stove), Airis will allow cooking to continue at a very high temperature – for example, in the case of searing or charring a steak. As this type of cooking requires close monitoring, Airis will not allow it to take place unattended, even for a short time.

With an app, it keeps getting better.

“This device works exactly as described and gives me great peace of mind as my relative is many miles away. Just as important though is the help and support from Unicook themselves, they made sure that the unit would do what I wanted it to do and could be fitted in the correct location. Even gave me a follow-up call to make sure everything was working as it should. I cannot fault the product or the service.”

Our elderly 90-year-old mother lives on her own and has always cooked for herself. We noticed that she regularly had burnt pans, an obvious indication that she was now becoming more forgetful... Plenty of support was provided for assistance with installing the unit... When there is any overheating the audible and flashing alarm which is picked up by the sensor does indeed cut the power supply to the hob until it is reset. Notifications are sent each time the alarm goes off and a weekly report is generated. We highly recommend the installation of the Airis for peace of mind and the support from the manufacturers and Unicook have been above and beyond to ensure that the system works as it should.

“I bought this for an elderly relative who lives by themselves and who can be occasionally forgetful. As they cook for themselves, this product seemed like the ideal solution for peace of mind – both for my relative and for the family as a whole. A local electrician installed the product within 20 minutes… My only concern when buying the product was that it may be over-sensitive like smoke alarms can sometimes be, but this has not been the case.”

“My mum lives alone since my Dad passed away a couple of years ago and I was worried about her cooking… Now she wouldn’t be without it as over Christmas the phone rang and she forgot she was cooking. She said when she went back to the kitchen, cooking had stopped as the food she was frying started to burn and the Airis cut the power”

Flintshire Council and North Wales Fire and Rescue Service - a study of the efficacy of BS EN 50615 technology using Airis Sense

Flintshire County Council logo

North Wales Fire and Rescue Service has experienced a number of incidents at the Flintshire Council- run tower blocks Bolingbroke Heights, Castle Heights, and Richard Heights, resulting from unattended cooking fires.

In response, the fire service set up a study in cooperation with the council and Unicook Ltd to assess the effect of stove guard technology in preventing the tower block fire and smoke incidents. The Unicook Airis product was chosen in part for its built-in data recording.

The council has experienced incidents placing residents at considerable risk with extensive (multi- apartment) damage from the sprinkler systems. In June 2021, an elderly gentleman was admitted to hospital with burns caused by a flash-over in an oil pan fire. Ten apartments were damaged by water following this incident. The council was therefore keen to find a cost-effective solution to protect the lives and wellbeing of residents as well as the properties. Having served in the fire service myself, I was particularly interested to see what impact stove guard technology could have.

A brief introduction to stove guard technology

A ‘stove guard’ is a device that cuts the power to a cooker or hob to prevent a fire. These are distinct from PIRs and timers etc as they only intervene when they determine there is a risk of fire. They prevent fires, and to a large extent smoke, resulting from unattended cooking.

Stove guard origins

The first stove guard was invented by a Swedish company called Cabinova in the 1980’s. The technology has now advanced considerably. In 2010, Norway mandated stove guards for all domestic kitchens. In practice, this meant that a stove guard must be installed in a new house or when a kitchen is renovated. Norway’s action created a substantial market for stove guards and led to considerable investment in developing the technology. There are now over 1 million devices installed in Europe. In the UK, 3 brands are available, namely Firechief Kitchen stove guard, Prefect Hobsensus and the Unicook Airis Sense.

BS EN 50615 standard (Part B)

In 2015, several manufacturers were consulted to create a pan-European standard to ensure stove guard products are tested and proven effective and, ultimately, to prevent stove guards from being confused with non-compliant cut-off devices triggered by timers or PIRs.

How they work

Stove guards consist of a sensor unit which fits to the wall/splashback behind the hob/cooker, to the underside of the extraction hood, or on the ceiling. A power controller (‘interrupter’) is wired between the power outlet at the wall and the hob/cooker. This is mounted behind a cooker or, in the case of a hob, usually behind the oven below. The sensor and power control units are linked by radio. An electrician is required for the installation, but no specialist training is needed.

Potential benefits

Stove guards prevent fires and, in some cases, greatly limit smoke. This reduces false as well as real alarms. This in turn can reduce calls to telecare alarm receiving centres and the fire services. As cooking is the root cause of 50% of domestic dwelling fires, the impact of a stove guard can be significant. Stove guards prevent sprinkler systems from activating.

Methodology

A sample of 42 apartments was fitted with a stove guard following individual assessments by the fire service and the council to identify residents considered to be at higher risk. At the end of the study, incident data from the council’s community alarm system both prior to and during the study would be compared.

Data from the stove guards would give detailed information about cooking sessions and potential incidents prevented. It would also provide a comparative risk profile of individual residents.

The stove guards were installed between March and August 2021 and the results were assessed using data collected up to 20th June 2022.

Findings

Flintshire community alarm data

During the study period, there was one community alarm triggered by cooking. This compares with 9 during a similar period preceding the introduction of stove guards.

While the Airis stove guard can in many cases react before significant smoke is produced, this depends on many variables and it is not possible in every case. However, in one such case, the community alarm was triggered by a smoking pan and the fire service was called. When the firefighters gained access to the property, they found that the stove guard had cut the power and had likely prevented a fire.

Assessment by Unicook

Airis cuts the power to prevent smoke, fires and damage to pans by analysing data from many sensing devices, and not all shut-offs would have prevented a fire. Although we cannot say with certainty how many fires may have been prevented, surface temperature data suggested that fires could have occurred without the stove guard’s intervention.

The widely varying ratio of activations to the number of times someone cooked reflects the varying degree of risk that a resident might leave cooking unattended or accidentally leaving a ring on after cooking. Most people occasionally leave cooking unattended or leave a ring on after cooking and therefore an occasional shut-off can be expected. However, as the data illustrates, in one case, the system intervened in almost 1 in 3 cooking sessions.

Summary

The study has helped to reinforce our knowledge of the efficacy of BS EN 50615 certified technology.

I would like to thank Flintshire Council and Unicook for their cooperation.
