Airis Stove Guard

Airis 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 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.

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 at any time, the power controller will prevent cooking to ensure the safety of the resident.

SecureFit wall bracket is available to prevent removal of the Multisensor. We generally supply and recommend these for student accommodation applications, and sometimes in assisted living schemes.

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 water leak sensors.

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.

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 at the stove, Airis will allow cooking to continue at a very high temperature – searing or charring a steak, for example. As this type of cooking requires close monitoring, Airis will not allow it to take place unattended, even for a short time.
