EN Installation Guide TriTech PIR/Microwave Intrusion Detector DS840LSN DS840LSN | Installation Guide | 1. General InformationEN | 2 Bosch Security Systems | 9/03 | PRELIMINARY 4998132113Ar11 1. 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. The DS840LSN can communicate and connect to all LSN Bus Systems. 2. Specifications Table 1: DS840LSN Specifications Standby Power No internal standby battery. For each hour of standby time needed, 4 mAh are required. For UL Listed Requirements, four hours (16 mAh) are required. LSN Supply Voltage 33 V maximum LSN Current Consumption 4.0 mA Alarm Signal Alarms are reported to the panel via the LSN Bus. Temperature -40°C to +49°C (-40°F to +120°F). For UL Certificated Installations, the temperature range is 0°C to +49°C (+32°F to +120°F). DS840LSN10.525 GHz (UL Listed) Microwave Frequency DS840LSNC10.588 GHz (UK, France) Coverage 12 m x 12 m (40 ft. x 40 ft.) Internal Pointability +2° to –18° Vertical Cover Tamper Tamper signaling via LSN Bus Options B335 Low Profile Swivel Mount Bracket and B338 Ceiling Mount Bracket. (The use of brackets may reduce range and increase dead zone areas.) Patents These detectors are covered under one or more of the following U.S. patents: #4,660,024, #4,764,755, #5,077,548, #5,208,567, #5,262,783, #5,450,062 and #5,670,943. Other patents pending. Compliance This device complies with Part 15 of the FCC Rules and with RSS-210 of Industry and Science Canada. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesirable operation. Changes or modifications not expressly approved by Bosch Security Systems can void the user's authority to operate the equipment. 3. Mounting 3.1Mounting Considerations • Never install the detector in an environment that causes a constant alarm in one technology; it should never be left to operate with the LEDs in a constant flashing green, yellow, or red condition. A detector with one technology in constant alarm will cause an alarm output whenever the other technology alarms. Good installations start with the LEDs OFF when there is no target motion. • Point the unit away from outside traffic (for example, roads, alleys, and parking lots). Microwave energy will pass through glass and most common non-metallic construction walls. • Avoid direct or indirect sunlight. • Point the unit away from glass exposed to the outdoors and objects that may change temperature rapidly (see Figure 1) The PIR detector will react to objects rapidly changing temperature within its field-of-view. Figure 1: Avoid extreme temperature change locations • Eliminate interference from nearby outside sources. • Avoid installations where rotating machines (such as ceiling fans) are normally in operation within the coverage pattern (see Figure 2). DS840LSN | Installation Guide | 3. MountingEN | 3 Bosch Security Systems | 9/03 | PRELIMINARY 4998132113Ar11 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.). The recommended height is 2.3 m (7.5 ft.). Mounting height for Pet Applications is 2 m (6.5 ft.). DS840LSN | Installation Guide | 3. MountingEN | 4 Bosch Security Systems | 9/03 | PRELIMINARY 4998132113Ar11 3.2Mounting the Detector See Figure 4 for location of features. 1. Remove the cover by inserting a thin flathead screwdriver into the locking tab hole at the bottom front of the detector, pressing in, and pulling the cover up and forward. Mount the unit with the terminal block up. 2. Remove the circuit board from the base by pulling outward slightly on one of the Circuit Board Locking Tabs (7). Do not touch the mirror surface. If you have touched the mirror surface accidentally, be sure to carefully clean wipe off fingerprints with a clean cloth and a mild non-abrasive cleaning solution. 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). Route to the rear of the base and through the wire entrance. Make sure all wiring is unpowered before routing. 9. Securely attach the base to the mounting surface. 10. Return the circuit board to the base. 11. Install the mirror using settings in Table 3.
