User manual VISONIC DUO

[. . . ] Be sure to adjust the MW range to the necessary minimum, to reduce the possibility of interference from lower floors. · Large reflecting objects (especially metals) within the coverage area can distort the microwave detector's coverage pattern. · Although the DUO is extremely immune to air turbulence and RF interference, avoid installation in a room with very strong air drafts or close to high-power electrical cables. It is also recommended to avoid aiming the detection pattern at sources of bright light and/or heat. [. . . ] Disconnect the AC mains from the alarm control panel and verify that the voltage supplied to the detector is above 9 Volts with the backup battery as the only power source. IMPORTANT: To comply with CE safety requirements, connect to CE-approved control panels with current-limited DC output. Note: Use RTV to seal the base opening(s) to prevent insects from entering the detector. Figure 3. Terminal Block Wiring 3. 3 Wiring Connect wires to the terminal block in the following order (Fig. 4): Terminal: TAMP (tamper switch) Connect to: A normally closed 24-hour tamper zone of the control panel. 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. 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. 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. 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. 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. It can only detect motion that disturbs the sensitive beam array spread within the protected space. DE1826 3 D. Motion will not be detected by PIRs if it takes place behind closed doors, floors, walls, ceilings, glass partitions, windows and shutters. The detection ability of the PIR detector may be reduced by malicious masking or by spraying various materials on the optical lens. The PIR detector's performance can decrease as the ambient temperature within the protected area approaches the range of 32° - 40°C (90° -105°F). The protection pattern provided by the microwave detector may be altered by metal objects or foil-covered insulation. Even the most reliable electrical devices, including this detector, may go wrong because of unexpected failure of component parts.
