DT15AM Fresnel based EN Grade 3 Dual Technology Detector with Active IR and Microwave Anti-Mask.

Varifocal optics and advanced digital signal processing guarantee impressive catch performance with excellent immunity to false alarm sources. Through-the-lens active IR and microwave anti-masking, provides outstanding detection coverage that is immune to almost all masking attempts.

This detector also combines advanced elements such as Anti-Stealth™ and the environmentally friendly Microwave Day Disable option along with all the features you would expect from a high quality detector.
As part of the detector platform range, reducing installation time has been a major driving force behind some of the design features included in the product. Variable mounting heights, adjustment free optics, selectable EOL resistors and quick-fit assembly are just some of these.
