Bracket (supplied). 
Note: Misaligning the detector in 
these brackets can reduce the 
detector’s range and increase the 
dead zone area.

This device complies with Part 
15 of the FCC Rules and with 
RSS-210 of Industry and Science 
Canada. Operation is subject to 
two conditions:
1. This device cannot cause 

harmful interference.

2. This device must accept 

any interference, including 
interference that might cause 
undesired operation.

Changes or modifi cations not 
expressly approved by Bosch 
Security Systems can void the 
user’s authority to operate the 
equipment.

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 traffi c. 

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.

SELV
Some countries require the relay to be connected to a 
Safety Extra-Low Voltage (SELV) circuit only.

 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 fi nger is the strongest and responds 
more quickly to an intruder’s presence. Every fi nger 
shown in the top view (3-1) has the same side view 
(3-2) confi guration.

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 fi t around the pole are recommended for fastening 
the detector mounting plate to the pole.

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.

AND/OR 
Mode

Determines if the detector alarms 
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.

ON: AND Mode (recommended)
OFF: OR Mode, you must also cut the 
jumper (4-10).

Day/Night 
Mode

Note: If the LEDs are enabled (SW0), 
then LED indications continue.

ON: With the control unit armed and this 
switch ON, the unit does not trigger an 
alarm during daylight.
OFF: With the control unit armed and this 
switch OFF, the unit can trigger an alarm 
day or night.

Power-up

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 fi rmly seated. Avoid 
pinching the wires.

2.  With a small fl at head screwdriver, turn the locking 

cam (9-1) 180

o

 to lock (9-2) the detector unit to the 

mounting plate. Avoid excessive force.

Note: Ensure the detector is fastened to the mounting plate and all wiring is connected and powered before 
beginning the Walk Test.

Note: Ensure the LED Disable (SW0) is on (refer to Section 7 DIP Switch Confi guration).

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 fl ashes 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 fl ashes, 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.
