DS840LSN Installation Guide EN TriTech PIR/Microwave Intrusion Detector
DS840LSN | Installation Guide | 1. 1. General Information General Information The DS840LSN is a microprocessor-based TriTech Passive Infrared/Microwave Intrusion Detector. Patented Passive Infrared and Microwave signal processing provides excellent catch performance with freedom from false alarms. EN | 2 3. Mounting 3.
DS840LSN | Installation Guide | 3. Mounting Figure 2: Avoid installing near rotating machines • Select a location likely to intercept an intruder moving across the coverage pattern (see Figure 3). Figure 3: Coverage Pattern Avoid mounting the detector in locations (such as above a doorway) where people can pass in close proximity (0.5 m / 1.5 ft.) of the detector. • The surface should be solid and vibration-free. • Mounting height range is 1.8 m to 2.4 m (6 ft. to 8 ft.).
DS840LSN | Installation Guide | 3. 3.2 Mounting EN | 4 3. Remove the Mirror Assembly (9). Carefully press with two fingers on the top end of the mirror assembly (9) and slide it out of the spring loaded tracks (11). 4. Break away the needed Wire Knockouts for the wire entrance (4). 5. Open two holes for surface or corner mounting (13). 6. Mark the location for the mounting screws using the enclosure as a template. 7. Pre-start the mounting screws. 8. Route wiring as necessary (see Section 4. Wiring).

DS840LSN | Installation Guide | 8. 8. Supervision Features Supervision Features The supervision features function as follows: • • 9. • • PIR/Microwave: The complete circuit operation of these subsystems is checked approximately every 12 hours. If the PIR or microwave subsystem fails, this will be communicated to the control panel. Default: The detector will default to PIR technology protection if the microwave subsystem fails. EN | 7 10.
