Designed for high security commercial indoor environments and large residences, the new ceiling mount DT8360 DUAL TEC® motion detector series with anti-mask* technology quickly detect intentional and accidental masks or attempts to block the detector, ensuring a trouble condition is immediately sent to the control panel. A 360° field-of-view and an extremely dense and wide detection coverage reduces the need for multiple detectors. Anti-masking technology combined with Honeywell patented sensing technologies, high quality mirror optics and microprocessor-based DualCore signal processing, will improve catch performance and reduce false alarm and trouble conditions.
