GUARDIAN2

Combined Motion and Presence Detectorfor Automatic Curved and Straight Sliding DoorsGUARDIAN 2• Overhead sensor for curved and straight sliding doors• Motion and presence detection in one unit• Digital Video Camera Technology• Easy teach of presence zone• Environmental adaptation• No Crosstalk between sensors• Separate motion and presence output• 2 x SPST relay outputs• Supply voltage: 12 to 24 VAC/DC• LED indication for: Power, Motion and Presence• CE, UL325 and TÜV approvedProduct DescriptionOrdering KeyGUARDIAN 2The GUARDIAN 2 is an over- head sensor for pedestrian slidingdoors.Thesensor has combined motion and presence (safe) detection zones. The sensor is based on CMOS camera technolo- gy and detectionon image processing. The motion zone reacts only to movement whereas the presence zone reacts to both movement and presence. The motion zone can be blanked in 3 directions (front, left and right) in order to avoid detec-tion ofunwanted objects. The presence zone is taught intothe sensor byrecogni- tion of standard test targets in the setupphase -itwill adapt to theshapeofa curved or straight sliding door. The presence zone also adapts to the surround- ings to work in different weather conditions. The sen- sor has separate outputs for the motion and presence zones as well as a test input totestthesensorfunction for each door cycle.Type SelectionHousing sizeOrdering no.210 x 77 x 58 mm GUARDIAN 2SpecificationsRated operational voltage (Ue) 12 - 24 VAC (12 - 24 VCA) RMS incl. ripple 50-60 Hz,±15% tolerance12 - 24 VDC (12 - 24 VCC)±15% toleranceTest input* Max. input current 5 mA Active high: ON > 9 VAC/VDCOFF < 6 VAC/VDC Active low:ON < 6 VAC/VDCOFF > 9 VAC/VDCNo load supply current (Ie)TypicalMax.192 mA230 mA@ 12V AC146 mA170 mA@ 12V DC103 mA120 mA@ 24V AC65 mA80 mA @ 24V DCSensitivityAdjusting in 7 stepsPresence zone reaction timeReaction time:210 ms (20% contrast, object speed 1 m/s, testTechnologyDigital video camera technologyPower ON delay5 secondsOutput function*Safety and Motion Zone Relay – SPST Common relay data: 1A DC 30VDCOperations minimum600.000 @ 0,5A, 50 VAC/30 VDCOperations minimum100.000 @ 1A, 30 VDCbody CA (DIN18650-1)) Fall time: 500 msMotion zone reaction timeReaction time:1,2 s (20% contrast, object speed 1 m/s, test body CA (DIN18650-1))Fall time: 500 ms* UL connected to supply class 2Specifications are subject to change without notice (01.06.2012) 1
