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|
|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
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.
