DUAL TEC Honeywell DT900AM-UK Long Range Detector

DUAL TEC Honeywell DT900AM-UK Long Range Detector

The fully featured DT7900 motion sensor achieves consistent protection at huge ranges and false alarm immunity has been improved through DualCore signal processing, uniform sensitivity optics and XBand technology. MaskAlert technology quickly detects intentional or accidental blocking and masking of the sensor, sending a trouble signal immediately once the mask conditions are met. Through a combination of these features you are provided with quality, secure detection that complies with PD6662, TS50131-2-4 & EN50131-1 Security Grade 3 Environmental Class II.

No matter if motion is detected at the edge of the pattern or directly in front of the sensor, the custom-designed Fresnal lens had constant sensitivity for human targets throughout the working area. With a working range up to a gigantic 24m x 21m, no movement within the detection pattern goes unnoticed.

The DT7900 stays reliable with constant diagnostics without compromising performance. In addition to performing a complete self-test on start up, microwave supervision run continuously, Passive infra-red supervision occurs once every hour and temperature compensation is logged and updated every 30 seconds. This results in a sensor that watches and adapts to it's changing environment while still fine-tuned to any and all suspicious movements.
