User manual VISONIC DUO

[. . . ] The superiority of the DUO over other dual detectors has been achieved by the advent of a True Motion RecognitionTM Installation Instructions algorithm (patented). This advanced motion analysis method provides the DUO with the ability to distinguish between the true motion of a human body and any other disturbances which invariably cause false alarms. Another unique feature of the DUO is the MW Motion Simulator circuit (patents applied for), which simulates the effect created by a human body moving in the MW field. The simulation routine is carried out periodically for self-testing, supervision and assurance that the MW detector operates properly. 2. [. . . ] Details: Once the cover is removed, the tamper switch opens. 3. 4 The Power-up Process After connecting the (+) and (­) terminals to the power source, the DUO starts a 60-second warm-up period, indicated by alternate flashing of the green and red LEDs. If the alternate flashing of the LEDs does not stop within 60 seconds, a failure has been detected by the self-test circuitry and the TRB output is activated 4. INDICATORS AND SELECTORS 4. 1 LED Indications The two LEDs (Fig. 3), which are hidden behind the lens when the cover is installed, are visible through the lens when illuminated. They are used to signal various alarm and trouble messages as shown in Table 1 below: Notes: 1. During walk testing, the first LED to respond is the green one. It illuminates steadily (MW detection) or flashes (PIR detection), depending on which detector discovered the movement first. Upon subsequent discovery of the movement by the other detector, the green LED will go off and the red LED will illuminate (alarm). If the green and red LEDs continue to flash beyond the warmup period, a malfunction has been diagnosed. Replace the unit without delay. 2 DE1826 Table 1. Interpreting the States of the LEDs GREEN Off On Flashes Off Flashes RED Off Off Off On Flashes Significance No detection MW walk-test detection PIR walk-test detection Alarm: MW + PIR detection Trouble is being detected by the self test circuitry, or Initial warm-up routine (stops 60 seconds after power up). Table 2. Set DIP switches SW-2 and SW-3 to ON (both LEDs are enabled). Temporarily mount the detector's cover in place. Walk across the detector's field of view in different directions, at various distances from the detector, and verify proper detection throughout the entire coverage area (the red LED will illuminate for 2 to 3 seconds). When done, remove the cover and set DIP switches SW-2 and SW-3 to OFF to prevent unauthorized people from tracing the coverage pattern. To assure proper function of the detector, the range and coverage area should be checked at least twice a year. Furthermore, it is recommended to perform a walk test at the far end of the coverage pattern to assure an alarm signal prior to each time the alarm system is armed. 6. WARNINGS Although this detector is a highly reliable device, it does not guarantee complete protection against intrusion. Even the most sophisticated detectors can sometimes be defeated or may fail to warn because: A. The detector will not function if the DC power supplied to it is incorrect or improperly connected. Detection is confined to the area covered by the detection pattern as adjusted by the installer. A PIR detector does not provide full volumetric coverage of the protected area.
