DS840LSN | Installation Guide | 1. General Information EN | 2Bosch Security Systems | 9/03 | PRELIMINARY 4998132113Ar111. General InformationThe DS840LSN is a microprocessor-based TriTechPassive Infrared/Microwave Intrusion Detector.Patented Passive Infrared and Microwave signalprocessing provides excellent catch performance withfreedom from false alarms.The DS840LSN can communicate and connect to allLSN Bus Systems.2. SpecificationsTable 1: DS840LSN SpecificationsStandby Power No internal standby battery. For eachhour of standby time needed, 4 mAhare required. For UL ListedRequirements, four hours (16 mAh)are required.LSN Supply Voltage 33 V maximumLSN CurrentConsumption4.0 mAAlarm Signal Alarms are reported to the panel viathe LSN Bus.Temperature -40°C to +49°C (-40°F to +120°F).For UL Certificated Installations, thetemperature range is 0°C to +49°C(+32°F to +120°F).DS840LSN 10.525 GHz (UL Listed)MicrowaveFrequency DS840LSNC 10.588 GHz (UK, France)Coverage 12 m x 12 m (40 ft. x 40 ft.)Internal Pointability +2° to –18° VerticalCover Tamper Tamper signaling via LSN BusOptions B335 Low Profile Swivel MountBracket and B338 Ceiling MountBracket. (The use of brackets mayreduce range and increase deadzone areas.)Patents These detectors are covered underone 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 theFCC Rules and with RSS-210 of Industryand Science Canada. Operation is subjectto the following two conditions:(1) This device may not cause harmfulinterference, and(2) This device must accept any interferencereceived, including interference that maycause undesirable operation.Changes or modifications not expressly approved byBosch Security Systems can void the user's authority tooperate the equipment.3. Mounting3.1 Mounting Considerations• Never install the detector in an environment thatcauses a constant alarm in one technology; itshould never be left to operate with the LEDs in aconstant flashing green, yellow, or red condition. Adetector with one technology in constant alarm willcause an alarm output whenever the othertechnology alarms. Good installations start with theLEDs OFF when there is no target motion.• Point the unit away from outside traffic (forexample, roads, alleys, and parking lots).Microwave energy will pass through glassand most common non-metallicconstruction walls.• Avoid direct or indirect sunlight.• Point the unit away from glass exposed to theoutdoors and objects that may change temperaturerapidly (see Figure 1)The PIR detector will react to objectsrapidly changing temperature within itsfield-of-view.Figure 1: Avoid extreme temperature changelocations• Eliminate interference from nearby outsidesources.• Avoid installations where rotating machines (suchas ceiling fans) are normally in operation withinthe coverage pattern (see Figure 2).
