4 Installation considerations
When installing the detector, observe the following installation considerations.
i
Notice!
Bracket use
Using a mounting bracket might reduce catch performance and false alarm immunity.
Reduced catch performance might invalidate regulatory certification on the installation.
Regulatory agencies do not approve bracket use. In order to optimize catch performance and
false alarm immunity, ensure that the motion detector is level both vertically and horizontally
and is mounted within the defined mounting height range.
Microwave energy passes through glass and most common non-metallic walls. The PIR
detector reacts to objects rapidly changing temperature within its field-of-view.
Detectors using passive infrared (PIR) technology recognize that all objects give off (emit)
infrared energy. The warmer an object is, the greater the amount of infrared energy is emitted.
The PIR receiver technology is designed to detect the change in infrared energy caused when
a target of a different temperature from a stable background passes through its field of view
(coverage area).
Point the detector away from:
Glass exposed to the outdoors.
Objects that might change temperature rapidly such as heat sources, air
conditioning outlets, or surfaces heated by sunlight.
Objects that small animals such as birds and mice might climb on (stairs,
shelves, ledges, furniture) and appear in the upper zones of the PIR which
are more sensitive. Small animals in close proximity in the field of view of
the detector might also cause false alarms.
Do not install:
In a location where direct sunlight shines onto the detector.
Outdoors.

Commercial Series TriTech and TriTech AM

Bosch Security Systems B.V. Installation manual 2022.01 | 01 | F.01U.401.708
Do not install:
Near rotating machines or other moving objects within the coverage
pattern.
Near objects that can block the field of view.
Where an intruder would walk only directly toward or away from the
detector.
In a location where the detector’s field of view is blocked by movable
objects such as boxes, furniture, doors or windows. The PIR detector
does not detect through glass.
Near doors and windows or other openings where cold or warm air can
flow onto the detector.

10 en | Installation considerations Commercial Series TriTech and TriTech AM
detectors
2022.01 | 01 | F.01U.401.708 Installation manual Bosch Security Systems B.V.
Do not install:
Above doors where an object can appear within 30 cm (1 ft) in front of
and/or underneath the detector to avoid false anti-mask alarms.
In a location where the detector would be too close to any movable
object that may cause anti-mask alarms.
For detectors with anti-mask:
Do not install:
Above doors where an object can appear within 30 cm (1 ft) in front of
and/or underneath the detector to avoid false anti-mask alarms.
In a location where the detector would be too close to any movable
object that may cause anti-mask alarms.
Do install:
Where an intruder is most likely to cross through the coverage pattern.
Within recommended installation height range measured from the floor.

5 Installation
This section includes hardware details and the instructions you need to install the motion
detector base.
5.1 Self-locking cam
The detector includes a self-locking cam for easy installation. Refer to the following
information to open and close the detector.
Open the detector and remove the base
1. Insert a flathead screwdriver into the locking tab hole.
2. Turn to the unlock position.
3. Slide, then lift the detector from the base.
Attach the detector onto the base
i
Notice!
When you remove the detector from the base, the cam automatically returns to the locked
position. When you place the detector onto the base, the cam must remain in locked position.
Do not manually change the cam once you remove the detector from the base; doing so
unlocks the detector and prevents you from putting the detector correctly onto to base.
1. Put detector onto the base.
2. Slide the detector up until you hear it "click."

5.2 Install options
Install the detector using the detector base.
Install the detector on a flat wall or in a corner. Refer to Mount directly –
for linking.
Install the detector using a bracket. Refer to Install on a bracket, page
14 .
Detector coverage patterns are designed for optimal performance when
installed level both vertically and horizontally. The detector base includes
a removable bubble level which helps you align the unit. Before drilling
the installation holes, use the bubble level to align the detector. Refer to
Bubble level.
Install directly to the surface
When installing onto a flat surface, select the installation holes shown in the figure. Drill or tap
out holes with a screwdriver.
Figure5.1: Left: wall installation, right: corner installation

14 en | Installation Commercial Series TriTech and TriTech AM
detectors
2022.01 | 01 | F.01U.401.708 Installation manual Bosch Security Systems B.V.
Install on a bracket
Mounting brackets help align the detector to a vertical angle and to correct imperfections
(non-perpendicular angles) of installation surfaces.
Choosing a mounting bracket:
– The B335 bracket allows a vertical pivot range of +10º to -20º and a horizontal pivot
range of ±25º.
– The B328 bracket installs on a single-gang box and allows rotation of the detector. The
bracket allows you to insert the wiring through the black tube section in the center of the
bracket mounting plate and through the back of the detector base.
– The B338 bracket designed for ceiling mounting allows a vertical pivot range of +7º to
-16º and a horizontal pivot of ±45º. The bracket allows you to insert the wiring through
the ceiling cavity and into the detector base.
When using a mounting bracket, pre-drill or tap out all of the mounting holes shown for that
bracket in the following figure.

i
Notice!
Using a mounting bracket might reduce catch performance.
Always install the detector within the recommended installation height, with or without a
mounting bracket.
Brackets are not investigated by UL.
Brackets are not EN50131 compliant.
i
Notice!
Do not use the bracket to tip the detector vertically, unless you intend to compensate for a
non-vertical surface. It may cause false alarms or reduced catch performance.

* If you use the bracket mount knockout for wires, run the wires between the walls marked
in red in the figure. With the wiring between the walls and behind the terminal block, other
features, such as EOL resistor jumper pins, cannot interfere with or puncture the wires.
5.4 Bubble level
The detector’s coverage pattern performs best when the detector is installed vertically and is
level both vertically and horizontally. The detector base includes a removable bubble level
which helps you align the unit. Use the bubble level to align the detector before drilling holes.
4Put the detector base on the surface and install it in place using one screw only. Do not
over-tighten the screw.
4Make sure the base is level from side to side.
4Remove the bubble level and place it into the round cavity on the right side of the base.
Make sure the base is level and not tipped forwards or back.
4Make adjustments until the base is level, and mark the remaining surface hole locations.

6.1.2 Alarm terminals
– Normally closed solid state voltage-free (dry contact) relay. The contacts are closed
(shorted) during warm-up and during normal operation when no alarm is detected, or if
only one technology (PIR or Microwave) is active.
– The alarm contacts change to open status under the following conditions:
– Insufficient input power
– Motion alarm condition (both PIR and microwave activity)
i
Notice!
When using the built-in resistors between the alarm terminals, there is a resistance value
instead of an open circuit. Resistor jumper switch selection determines the resistance value
6.1.3 Tamper terminals
– Normally closed voltage-free (dry contact) switch. The tamper terminals change to an
open state if the detector separates from the mounting base or if the motion detector is
removed from the mounting surface.

6.1.4 Trouble terminals
– Normally closed solid state voltage-free (dry contact) relay. The contacts are closed
(shorted) during warm-up and during normal operation when no trouble condition is
detected.
– The trouble contacts change to open status under the following conditions:
– Insufficient input power
– Self test fault condition
– Anti-mask alarm condition
– Low power level detected
i
Notice!
When using the built-in resistors between the trouble terminals, there is a resistance value
instead of an open circuit. Resistor jumper switch selection determines the resistance value.
Connect the alarm, tamper, and trouble contacts to a SELV circuit only. Do not use with
capacitive or inductive loads.
!
Warning!
Connect the alarm, tamper, and trouble contacts to a SELV (Safety Extra-Low Voltage) circuit
only. Do not use with capacitive or inductive loads.
Only apply power after all connections have been made and inspected. Do not coil excess
wiring inside the motion detector.
Low voltage trouble condition
If the power supply voltage falls between 6.5 V and 8 V, the detector activates the trouble
output (open condition) to indicate that while the detector is still operational, further voltage
reduction below will result in functional failure. This condition may occur multiple times if the
detector's power line is overloaded. Typical line overload causes include multiple detectors
being powered from the same line, when the varying overall current consumption of all
connected detectors cause arbitrarily changing voltage levels due to varying voltage drops on
the wire.
i
Notice!
Do not confuse this condition with a situation when the supply voltage is insufficient for the
detector to operate without failure. In a situation where the supply voltage drops below 6.5 V,
both the alarm and the trouble output activate simultaneously.
6.2 EOL resistors overview
The detector includes multiple built-in status resistors to simplify the wiring when matching
the alarm outputs with the control panel input loop resistance specifications. Use the Resistor
jumper switch settings to match the loop circuit shown in the alarm control panel
documentation.
i
Notice!
Built-in resistor values cannot meet every control panel resistor value requirement. If the
connected control panel resistor values and loop structure do not match the combinations
allowed by the built-in resistors, make sure to leave the resistor jumper switch settings to off
and use only external resistors.
