Ceiling Mount Dual Tec® Motion Sensor with Mirror Optics and Anti-Mask* 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. Beneath the two-piece, easy-open enclosure, installers will find easy access to the wiring terminal and built-in features which simplify the installation experience and reduce installation time. Furthermore, the new detectors come equipped with integrated EOL resistors with easy selectable DIP switches** or two wire V-Plex® technology***. A flexible mounting height adjustment dial and an enhanced flash light walk test will reduce time and trips up and down the ladder. * DT8360ACM and DT8360ACM-SN only ** DT8360CM and DT8360ACM only *** DT8360CM-SN AND DT8360ACM-SN only
