Product name: laser correlation detector "double beam" Product model: DA208Y - 2 The alert level: double beam Docking way: Exib Ⅱ BT6 (explosion protection with the optional) wavelength: 980 nm (not visible) Warning distance: 0 ~ 1000 m is optional Signal recognition: each beam independent signal identification, multiple beam same direction signals of non-interference in each other Alarm way: can choose single or double beam beam interrupt call the police Working voltage: AC/DC12V (support wide voltage intelligent management mode) Working current: launch 180 ma, receive 180 ma Relay output way: two groups often open/closed contact, often can support the linkage Contact capacity: AC120V/DC24V 1 a Max level effectively Angle adjustment: horizontal plus or minus 15 °, vertical + 15 ° Alarm time: 10 s (optional alarm output time) Response time: 20 ~ 380 ms ms (trigger alarm response time) Working temperature: - 45 to 80 cent.degree Acceptance Angle: > 13 ° Waterproof level: IP67 Size: column: 70 * 90 * 460 mm chassis: 120 * 100 mm Mounting holes: hole center 122 * 102 (4) 6.5 * 14 mm hole Use environment: the wild, outdoor and indoor Product scope Mainly aimed at the field, outdoor and other areas, such as: railways, subways, factories and enterprises, large-scale oil depots, terminals, bank vault, electricity, museums, galleries, schools, farms, airports guard, prison fortification, military areas, armory, ammunition depots, border lines and the need to focus strengthen surveillance, prevention of cross-border thieves wild outdoors all places, and have important items of shops and warehouses, more security guarantees for home burglar. The false positive rate is one ten thousandth of DAAO TIMES commitment to you. Product introduction Daaotimes laser correlation alerter with invisible light 980 nm wavelength laser technology, easily concealed protection, the shape of the column makes products could vertical installed on the wall or be installed in a tilting Angle of 90 degrees, which according to the characteristics of the building and security requirements. The installation key point is to post the basis fixed and no shift or shaking. Strong penetrating power of laser, very low rate of false positives, far prevent distance makes laser beam do not like radio waves, infrared light that can be influenced by the background light and interference (also does not affect product performance in the hot sun protection).the detection range can be adjusted from 0 to 1000 meters according to the requirement. Products elegant appearance, convenient installation, good waterproof performance is suitable for use in indoor, outdoor, outdoors, such as protection operation, can also support monitoring probe linkage lights, etc.
