Stove Alarm SA101 Features

  • Attaches to the range hood with magnets or to the wall with screws
  • Identifies overheating very early in the development of hazardous situations
  • Intelligently learns from and adjusts to the individual cooking styles
  • Does not react to fumes produced with cooking fat, to steam or dirt on the alarm
  • Manual resetting of the alarm
  • Automatic resetting of the alarm triggered by falling temperature
  • Works on all kind of cookers (gas, electrical, dual-fuel)
  • Low-battery alarm, can be postponed for 12 hours
  • Audible alarm signal 90dB/10 cm
  • Battery life up to 5 years
  • Dimensions 30x60x45 mm

This is the latest version of this popular stand alone safety device which is attached magnetically to a cooker hood or to the wall using screws. When the surrounding temperature rise has increased significantly it will transmit an alarm to alert the user but does not switch the cooker off. It does not interfere with normal cooking activities. It is able to be reset using the  button.

This is ideal for the forgetful and compliments smoke detectors. It is battery operated with an approximate 5 year battery life depending on the number of alerts.

In addition to the stand alone Stove Alarm SA101 there is also available a Cooker Safety System kit Stove Guard SGK510 which includes a smarter version of the Stove Alarm – the Intelligent Sensor incorporating an extra I.R. sensor and radio transmitter, together with the Stove Guard cut off switch. When the Intelligent Sensor of the SGK510 detects a potential of a cooker top fire, it sounds an alert and then sends a radio signal to the Stove Guard which will turn off the cooker electricity supply, so cutting off the ignition source to the fire. There is a short pre-alarm delay before this happens to give time for someone to take action. The Stove Guard cut off switch will also be activated by the audio signal from other nearby detectors such as Smoke, Carbon Monoxide or gas detector.

There is an alarm output socket (3.5mm stereo jack plug) on the Stove Guard so that a Telecare type transmitter can be plugged in to send a signal to a Lifeline telephone to alert a social alarm monitoring centre if required.

The Cooker Safety System could be particularly useful to Housing Associations especially with vulnerable tenants. Not only has it the potential to save lives but also to reduce the likely hood of expensive damage/redecoration as well as possible tenant relocation, making it very cost effective. It is also proving useful in student university kitchens where students leave cooker hobs unattended whilst cooking.

The two pictures below illustrate the easy installation of the cooker connection to the Stove Guard. This installation was undertaken in the Lambeth Council Assistive Technology Show Flat as part of a demonstration I organized between the Manufacturers, myself as their representative, the Lambeth AT Lead, London Fire Brigade and Department of Communities & Local Government. The previous 300 Sensor illustrated, has since been improved to the new SGK 550 sensor with improved features.

Stove Guard SGK 510  is a new model addition to the Stove Guard cooker safety system range featuring a new Intelligent Sensor incorporating both Infra Red and NTC sensors to monitor the cooker hob heat, together with the Stove Guard cooker cut off device.. The new Intelligent Sensor,  which has a built in solar battery charger so the batteries will not require replacement for some 10 years! It also has a safety device to isolate the cooker if the Intelligent Sensor is removed – accidently or on purpose. In addition the SGK500 has a built in self-test facility to ensure it is working OK everytime the cooker is switched on and conforms to the newly introduced EU Standard and Directive for these type of devices.

The Stove Alarm SA101, 300 Stove Guard and GSK 500 Stove Guard Cooker Safety Systems are additional safety devices that do not necessarily cover all possible hazardous situations, but that significantly improves the safety of the cooker.


Every year, a significant number of fire incidents happen in the United Kingdom, many of them leading to deaths and injuries. According to Fire Statistics, UK, there were a total of 43,351 fire incidents in the year 2007. More than half of these were caused by cooking appliances.

The source of fires in domestic dwellings in UK

Sources of ignition

There are many kinds of cooking appliances; they differ in design, size, and type of fuel. Most cookers use gas or electric power. Statistics show that electric cookers cause more than double the number of fires caused by gas cookers; however, this probably reflects the fact that there are far more of them in use, rather than suggesting that they are more dangerous.

In 2007, electric cookers were the cause of 63% of all fires ignited by cooking appliances.

Causes of accidents and fire

Food left unattended while it is cooking is the main cause of fires, believed to be the source of more than 50% of all fires in the home. Other causes include turning cooking appliances on by mistake or Failure to turn them off after cooking, and children or pets in the kitchen.

Chip pans / hot fat frying

  • Never fill a pan more than a third full with fat or oil.
  • Dry chips/food before putting them in the pan.
  • If the oil has started smoking turn off the heat and leave the oil to cool down, otherwise it may catch fire.
  • Turn off the hob if you have to leave the kitchen whilst cooking.

In 2008 a Sinteff report concluded:

it would be beneficial in social terms to let all households invest in a kitchen stove alarm, which is set off when the electric cooker becomes overheated, such as when a pan boils dry. Such alarms are already on the market. If they were installed in all homes, they would save three to six lives a year, the report shows.”

Innohome is tested by SINTEF in 2012

The Innohome Stove Guard is tested by SINTEF (NBL F12102), the largest independent research organisation in Scandinavia.

“The Innohome Stove Guard (control unit SFC300RF in combination with intelligent heat sensor SA102RF) cut off the electric power supply with satisfactory margin without unnecessary alarm before spontaneous ignition temperature in the scenarios tested was reached.”

“The tests performed did not lead to fire.”
