Note: Misaligning the detector in
these brackets can reduce the
detector's range and increase the
dead zone area.
Compliance: OD850-F1 complies with Part

RSS-210 of Industry and Science
Canada. Operation is subject to
two conditions:
1. This device cannot cause
harmful interference.

any interference, including
interference that might cause
undesired operation.
Changes or modifications not
expressly approved by Bosch
Security Systems, Inc. can void
the user's authority to operate the
equipment.

Installation Considerations

Never install the detector where the PIR or microwave
is in constant alarm (LED on). The LED is off when
properly installed.
Point away from traffic.
Avoid installing where hanging signs, trees or other
objects that the wind can move are within the coverage
pattern or where wildlife might move within the
coverage pattern.
The mounting surface must be solid and vibration-free.
UL Listing Requirements
The unit shall only be installed outdoors for primary
protection in high security installations where unwanted
alarms would be tolerated. Otherwise, the outdoor
device should be used for supplementary protection
only, and be connected to a trouble zone or to a zone
that is not programmed for off-premises transmission.
Warning!
- Apply power only after all connections are made
and inspected. Do not coil excess wiring inside
detector.
- Do not connect any terminal to any power supply
providing more than 25 VDC.

Coverage Patterns
Microwave coverage
PIR coverage
Look-down zone
Note: When choosing the appropriate mounting height
for your application (particularly, when the terrain is not
level) the upper finger is the strongest and responds
more quickly to an intruder's presence. Every finger
shown in the top view (3-1) has the same side view
(3-2) configuration.
5
Tamper Options
The unit has a built-in cover tamper that signals when
the detector unit (4-9) separates from the
mounting plate (4-1). The unit can also be installed so
the tamper signals if the entire unit is pulled away from
the surface on which it is mounted.
Note: The wall and cover tamper option are only
available when the unit is surface mounted. The cover
tamper is available with all mounting options.
Determine whether the tamper switch is to be used as
a cover tamper or a wall and cover tamper:
- Wall and cover tamper: Use the appropriate
screw to fasten the mounting plate tamper section
(5-1) to the wall.
- Cover tamper: Do not attach the mounting plate
tamper section (5-1) to the wall.

Attaching Detector to Mounting
Plate
1. When all wiring is connected to the detector but not
to the power supply and all the settings are made,
slide the detector unit (4-9) onto the mounting plate
(4-1) and down until it is firmly seated. Avoid
pinching the wires.
2. With a small flat head screwdriver, turn the locking
cam (9-1) 180 o to lock (9-2) the detector unit to the
mounting plate. Avoid excessive force.
4
Mounting
1. Select a mounting location. Mount the sensor where an intruder is most likely to cross the coverage pattern.
2. Mount the detector 7 ft to 9 ft (2.1 m to 2.7 m) above the ground. Recommended: 7 ft (2.1 m)
Note: Mounting height recommendations are based on level surfaces. If the terrain is not level, adjust the
mounting height and detector angle to provide the best coverage.
3. Slide the mounting plate down (4-1) until you hear a click, and remove it from the cover.
4. Mount the mounting plate using one of these options:
Note: Do not remove the waterproof label from the mounting plate (4-2). Push the mounting screws or wiring
knockouts through the label as needed.
- Surface mount using a single-gang electrical box.
1. Install a single-gang electrical box at the detector location.
2. Attach the mounting plate (4-3) to the single-gang box with the appropriate screws.
- Surface mount without an electrical box.
1. Select an appropriate location.
2. Using the mounting plate (4-1) as a template, mark the location of the mounting screws and the wire run.
3. Attach the mounting plate (4-1) to the wall with the appropriate screws.
- Surface Mount using the supplied B335 Bracket or an optional bracket. Use the bracket's instructions to
attach the bracket to the appropriate mounting surface.
- Attach the B335 Bracket to the mounting plate. (4-4).
- Attach the B328 Bracket to the mounting plate. (4-5).
- Attach the B338 Bracket to the mounting plate. (4-6).
- Pole Mount using the supplied bracket.
Note: Do not mount to fence posts that might sway in the wind.
- Attach the bracket (4-7) to the mounting plate (4-8) using the appropriate screws and mounting
holes.
- Two hose clamps (not supplied) large enough to fit around the pole are recommended for fastening
the detector mounting plate to the pole.

DIP Switch Configuration
(7-1) On
(7-2) Off
Switch Feature Description
0 LED Determines if the LED lights during
Disable alarm situations.
Default factory setting: ON
1 PIR Standard: Minimizes false alarms.
Sensitivity Tolerates environmental extremes
Intermediate: Use where an intruder
might cover only a small portion of the
protected area.
Tolerates normal environments.
Note: The detector is shipped in
Standard Mode.
2 and 3 Timed Form "C," unsupervised, timed relay
Relay contact that transfers 1 sec after an
Outputs alarm. It follows a user-selectable
timer. The time expires at the time set
after the last alarm. It resets on each
new alarm.
4 AND/OR Determines if the detector alarms
Mode in the AND mode (when both
technologies simultaneously sense an
alarm condition) or in the OR mode
(when either the PIR or Microwave
technology senses an alarm state).
Note: The OR mode is not
recommended for most installations.
The OR mode provides faster
detection in some conditions. It
can also increase the likelihood of
nuisance alarms because the detector
activates the alarm relay based on
input from a single technology.

Walk Test
Note: Ensure the detector is fastened to the mounting plate and all wiring is connected and powered before begin-
ning the Walk Test.
Note: Ensure the LED Disable (SW0) is on (refer to Section 7 DIP Switch Configuration).
Note: To avoid false alarms, set the microwave range (10-1) to its minimum setting before starting the Walk Test.
Microwave coverage
PIR coverage
1. Wait at least 2 minutes after power up to start the
Walk Test.
The LED flashes red until the detector stabilizes and
no movement is detected for 2 seconds.
2. Watch the LED as you walk towards the edge of the
pattern (10-2). The LED lights at the outside edge of
the coverage range.
3. Repeat Step 3 from different directions until you
adequately verify the coverage pattern.
The green LED lights, identifying the PIR pattern
edge.
The green LED flashes, identifying the microwave
pattern edge.
4. Repeat Step 3 from the opposite side.
5. If the required range is not achieved, increase the
microwave adjustment (10-1) by turning it clockwise
slightly.
6. Repeat the walk test and adjustments until you
reach the farthest edge of coverage needed.
