Vesda Xtralis FTD-8865-S Failsafe Thermography Detector (FTD)

The Failsafe Thermography Detector (FTD) is a bi-spectral (IR & Visual) smart edge device that has been specifically designed for early warning  heat-detection. It can directly communicate with Fire Alarm Control Panel (FACP) for Pre-Alarm, Alarm and Fault conditions. The thermography detectors provide fire detection solutions where traditional smoke/fire  detectors cannot cope with high smoke and dust conditions as part of normal operating conditions. Their applications target the critical infrastructures and challenging environments such as: waste recycling, tunnels, machine and process supervision, power stations, etc.

Operation

Every object above 0° Kelvin (-273 °C or -459 °F) emits infrared energy, invisible to the human eye. Long wavelength IR microbolometers can detect this energy and feed as electrical signals to the processing unit. The measured IR/heat is visualized in artificial colours on screen. The heat intensity across surfaces and objects is measured and displayed on pixel level. This allows to exactly pinpoint the location of a developing heat source.

The system allows to set various alarm levels in several regions of interest (ROI) allowing to signal both pre-alarms and alarms through on-board relays. Thermal imaging technology is contactless and non-invasive. The detector continuously supervises for various fault conditions and signals these via an onboard failsafe relay. The FTD range detectors connect very fast and are user-friendly to any industry standard FACP in the same way traditional smoke/fire detectors do. The bi-spectral camera allows visual camera as needed by switching from IR mode to Visual mode.

Configuration

For an accurate detection, FTD range allows several regions of interest to be set with different detection levels to suit a wide range of environments. The system allows for alarm delays and security temperature per ROI. Next to the relay outputs, the detectors feature Ethernet out for rich data to powerful management software. They also offer an SD card slot for local storage of alarm snapshots and/or video clips.
