Installation Instructions DS825, DS825T, DS840, DS840T TriTech PIR/Microwave Intrusion Detectors 1.0 General Information The DS825 Series and DS840 Series are microprocessor-based TriTech Passive Infrared/Microwave Intrusion Detectors that provide immunity to false alarms caused by pets [a dog up to 100 lbs. (45 kg) or up to 10 cats, and other small animals such as birds and rodents]. Patented Passive Infrared and Microwave signal processing provides excellent catch performance with freedom from false alarms. 2.0 Specifications • Input Power: 6 to 15 VDC, 15 mA DC nominal (up to 35 mA DC during walk testing). • Standby Power: No internal standby battery. Connect to DC power sources capable of supplying standby power. For each hour of standbytime needed, 15 mAh are required. For UL Listed Requirements, four hours (60 mAh) are required. • Alarm Relay: Silent operating Normally Closed reed relay. Contacts rated 3 W, 125 mA, 28 VDC maximum for DC resistive loads; and protected by a 4.7 Ω,1/2 W resistor in the common "C" leg of the relay. Do not use with capacitive or inductive loads. • Temperature: -40°F to +120°F (-40°C to +49°C). For UL Certificated Installations, the temperature range is +32°F to +120°F (0°C to +49°C). • Microwave Frequency: DS825(T)/DS840(T): 10.525 GHz (UL Listed) DS825TA/DS840TA: 10.687 GHz (Export only, not UL Listed) DS825TB/DS840TB: 9.9 GHz (Export only, not UL Listed) • Coverage: DS825 Series: 25 ft. x 25 ft. (8 m x 8 m) DS840 Series: 40 ft. x 40 ft. (12 m x 12 m) • Internal Pointability: +1° to -18° Vertical. • Optional Tamper: The DS825T, DS825TA, DS825TB, DS840T, DS840TA, and DS840TB have a Normally Closed (with cover on) tamper switch. Contacts rated at 28 VDC, 125 mA max. Connect the tamper circuit to a 24-hour protection circuit. • Options: B335 Low Profile Swivel Mount Bracket and B338 Ceiling Mount Bracket. (The use of brackets may reduce range and increase dead zone areas.) • Reading Bosch Security Systems, Inc. Product Date Codes For Product Date Code information, refer to the Bosch Security Systems, Inc. Web site at: http://www.boschsecurity.com/datecodes/ • 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. 3.0 Mounting 3.1 Mounting 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 tri-color LED in a constant 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 LED OFF when there is no target motion. The best installations will have background noise voltages below recommended limits. • Point the unit away from outside traffic (e.g. roads, alleys, and parking lots). NOTE: 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. NOTE: The PIR detector will react to objects rapidly changing temperature within its field-of-view. • Eliminate interference from nearby outside sources. • Avoid installations where rotating machines (e.g. ceiling fans) are normally in operation within the coverage pattern. • Select a location likely to intercept an intruder moving across the coverage pattern. • The surface should be solid and vibration-free. • Mounting height range is 6 to 8 ft. (1.8 to 2.4 m). The recommended height is 7.5 ft. (2.3 m). Mounting height for Pet Applications is 6.5 ft. (2 meters). 3.2 Mounting the Detector • 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. NOTE: Mount the unit with the terminal block up. • Remove the circuit board from the base by pulling outward slightly on one of the Circuit Board Locking Tabs (see Figure A).
