Bosch DS820i Series User manual

1.0 Description
The DS820i and DS820iT Series are high performance TriTech Passive Infrared (PIR)/Microwave (MW) Intrusion Detectors which use advanced signal
processing to provide outstanding catch performance and unsurpassed false alarm immunity. They are designed to detect movement of a human body in the
interior of a structure as it moves across the Detector’s field of view. When motion is detected, the Detector sends an alarm signal to the control panel. With
Bosch Security Systems Pet Friendly® pet immunity, these Detectors will not detect a dog up to 100 pounds (45 kg) or two 60 pound (27 kg) dogs, up to 10 cats,
numerous rodents or flying birds. This pet immunity feature has not been tested by Underwriters Laboratories.
• Input Power: 6 to 15 VDC, 16 mA nominal standby (up to 35 mA
during walk testing and alarm). Use only Limited Power
Source up to 5 A maximum.
• Standby Power: No internal standby battery.
For UL Certificated
installations, 4 hours (64 mAh) standby power must
be provided
by the control unit or by a Listed burglary
power supply.
• 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: The storage and operating temperature range is
-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:
DS820i/820iT: 10.525 GHz (UL Listed)
DS820iTA: 10.687 GHz (Export only, not UL Listed)
DS820iTB: 9.9 GHz (Export only, not UL Listed)
•Coverage: 20 ft. by 20 ft. (6 m by 6 m)
•Tamper: (“T” models only) Normally Closed (with cover on).
Contacts rated at 28 VDC, 125 mA max. Connect
tamper circuit to a 24-hour protection circuit.
•Options: B335LowProfileSwivelMountBracket,B338Ceiling
Mount Bracket. (The use of brackets is not
recommended for pet applications and may reduce
range and increase dead zone areas).
•Patents: This product is covered by one or more of the
following U.S. patents: #4,660,024, #4,764,755,

3.10 Microwave range is pre-set. Field
adjustment is not required.
NOTE: If you choose to adjust the range, set
the adjustment as low as possible for
proper catch performance. Be sure to
walk test throughout the coverage
pattern after any adjustment.

This detector contains an environmental
stabilization circuit which requires
approximately 2 minutes after initial
power-up to warm up. During this time
the detector will not respond to any
movement.
Please wait 2 minutes after initial power-up
to perform any walk tests.
