Early fire detection

FireVu is introducing what it claims is the first fire detection technology that combines visual smoke detection (VSD), flame detection and temperature sensing technology in the form of a built-in thermopile.

The Multi Detector can identify and analyse smoke and heat patterns to raise alerts. VSD technology operates by identifying characteristic smoke patterns across a video image. It analyses changes in a range of variables such as colour, brightness, contrast, shape, edge content, motion, colour matching and loss of detail to alert operators early to potential fire danger.

The addition of a thermopile to detect radiated heat acts as a double check because it uses a different technology, and is designed to help distinguish potential triggers for false alarms. Steam and dust clouds, for example, can be excluded as danger points by setting heat criteria above temperatures likely to be encountered.

Simon Jenkins, product manager for FireVu, says: “VSD is already an effective and proven technology, so combining it with thermal radiated heat detecting technology gives us a solution not offered by competitors.”
