Fires can be caused by various factors. Faulty electronics can cause smouldering and braising fires to spread and develop over hours and days. In order to monitor a room or area not only for high surface temperatures but also for gases that are produced, early fire detection is an important preventive measure.
The 4-factors of early fire detection by the new Kentix MultiSensor-TI are explained and defined in detail below.

1st factor: surface temperature

Very hot surface temperatures emit strong infrared radiation. This radiation is picked up by the MultiSensor-TI with an infrared sensor and output as a thermal image. In this way, different temperature ranges in rooms or on machines can be determined very accurately. If these hotspots exceed a certain value, an alarm is given in time. The surface temperature can only be measured in the direct viewing window of the infrared sensor. Hidden or internal temperature hotspots are not detected, or only when the surface is reached.

2nd factor: CO gas detection

Carbon monoxide (CO) is a tasteless, odourless, colourless and toxic gas. Carbon monoxide (also known as carbon monoxide) is produced by the incomplete combustion of various carbonaceous substances without sufficient oxygen supply. These burns can occur over a long period of time. Even before smoke or even flames are visible, the Kentix MultiSensor-TI will detect the CO gas and trigger an alarm.

Possible human adverse effects due to carbon monoxide exposure are listed in the following table:

Carbon monoxide value
in parts-per-million
Consequences for humans
200 ppm (0,02%)headache, fatigue, dizziness, sickness
400 ppm (0,04%)

Headache, life-threatening after 3 hours

800 ppm (0,08%)Dizziness, sickness and cramps within 45 minutes
1600 ppm (0,16%)Headache, dizziness and sickness after 20 minutes, unconsciousness
within 2 hours, death possible within one hour
3200 ppm (0,32%) Headache, dizziness and sickness after 5 minutes. Death within 30 minutes
6400 ppm (0,64%)

Headaches, dizziness and sickness after 1-2 minutes. Seizures, respiratory arrest and death in less than 20 minutes

12800 ppm (1,28%)unconsciousness after 2-3 breaths, death in less than 3 minutes

3rd factor: air pollution

The Kentix MultiSensor-TI detects a rapid change in air quality in a room. As soon as a strong air pollution is detected, which can be caused by various reasons, an alarm is reported. In contrast to surface temperature detection, the air quality sensor monitors not only the direct viewing window, but also concealed areas around the environment. The MultiSensor-TI detects the proportion of volatile organic compounds (VOC) and can thus determine an Indoor Air Quality Index (IAQ). The subdivision of the IAQs can be found here: Measurement of air quality according to IAQ index

4th factor: air temperature

The integrated temperature sensor measures the rise in air temperature in a room. If the value rises sharply in a very short time and exceeds a defined threshold value, the Kentix MultiSensor-TI triggers a temperature alarm.
