Professional Series TriTech AM Detectors with
Anti‑mask, LSN are two-wire bus units for commercial
and high security indoor applications with the Bosch
Local Security Network (LSN). Each detector sends
alarm, trouble, tamper, or anti-mask signals through
serial communication on the LSN bus. With LSN, there
can be a short or open at any point in the loop and all
devices still function. The LSN technology supports
flexible structures, efficient programming, and high
current levels.
MANTIS anti-mask technology makes obscuring the
detector view nearly impossible for intruders. Sensor
Data Fusion technology ensures that alarm conditions
are based on precise information. The powerful
combination of unique features in the Professional
Series delivers superior catch performance and
virtually eliminates false alarms.

System overview
LSN Technology
This detector is a two-wire unit for use with the Bosch
Local Security Network system (LSN and LSN
Improved). It communicates alarm, trouble or tamper
conditions through serial communication on the LSN
bus.
The detectors send the following condition signals
through LSN serial communication:
• Alarm, anti-mask, tamper, or trouble
• Remote self test response
The control panel sends the following condition and
status commands through LSN serial communication
to the detector:

• Device reset
• Armed/disarmed status
• Alarm, anti-mask, tamper, and trouble signals*
• LED controls for alarm, anti-mask, and trouble
• Anti-mask on/off
• Selectable coverage range
• Remote self test
*The control panel can put the signal into latch or real
time mode.
Functions
Sensor Data Fusion Technology
Sensor data fusion technology is a unique feature that
uses a sophisticated software algorithm to gather
signals from five sensors: two pyroelectric sensors, a
range adaptive radar sensor, a room temperature
sensor, and a white light level sensor. The
microcontroller analyzes and compares the sensor
data to make the most intelligent alarm decisions in
the security industry.
Tri-focus Optics Technology
Tri-focus optics technology uses optics with three
specific focal lengths: long-range coverage, middlerange coverage, and short-range coverage. The
detector applies the three focal lengths to 86
detection zones, which combine to make 11 solid
curtains of detection. Tri-focus optics technology also
includes two pyroelectric sensors, which deliver twice
the standard optical gain. The sensors process
multiple signals to deliver precise performance
virtually free of false alarms.
Range Adaptive Radar
The microwave transceiver automatically adjusts its
detection thresholds based on input from the PIR
sensors. Integrating the target distance information
from the PIR significantly reduces false alarms from
the microwave Doppler radar.
MANTIS Anti-mask Technology
MANTIS (Multi-point Anti-mask with Integrated Spray
detection) uses patented prism lenses and active
infrared detection to provide industry-leading
protection against all known forms of attack. MANTIS
complies with the latest world-wide regulatory
standards for detecting objects covering or placed in
front of the detector. MANTIS is sensitive to materials
regardless of texture or color, including fabric, paper,
metal, plastic, tape, and spray. When MANTIS
identifies a masking material, the detector sends an
anti-mask signal to the control panel through serial
communication on the LSN bus.
Installers can disable or enable the anti-mask feature.
This task is performed at the control panel.
Active White Light Suppression
An internal light sensor measures the level of light
intensity directed at the face of the detector. Sensor
data fusion technology uses this information to
eliminate false alarms from bright light sources.
Available Coverage
The standard coverage is 12 m x 12 m (40 ft x 40 ft).
Installers can select short range coverage of 8 m x
10 m (25 ft x 33 ft) at the control panel (serial
communication from control panel to detector over
the LSN bus).
Dynamic Temperature Compensation
The detector automatically adjusts PIR sensitivity to
identify human intruders at critical temperatures.
Dynamic temperature compensation detects human
body heat accurately, avoids false alarms, and delivers
consistent catch performance at all operating
temperatures.
Cover and Wall Tamper Switch
When an intruder removes the cover or attempts to
separate the detector from the wall, a normally‑closed
contact opens causing the detector to send a tamper
message to the control panel.
Remote Walk Test LED
Users can enter a command through a keypad, a
control center, or programming software to enable or
disable the walk test LED.
Draft, Insect, and Small Animal Immunity
The sealed optic chamber provides immunity to drafts
and insects, reducing false alarms. Small animal
immunity reduces false alarms caused by animals less
than 4.5 kg (10 lb), such as rodents.
Remote Self Test
When the control panel sends a remote self test
message to the detector, the detector tests its
detection systems. If any system fails, the detector
sends a self test fail message to the control panel. If
all systems pass, the detector sends a self test pass
message to the control panel. If the system is
configured for local LED control, the alarm LED
activates for four seconds following a successful test
or flashes after a failed test.
Flexible Topologies
Each detector can be added to flexible LSN structures
such as loops, stubs, T-tap, tee-offs, and mixed.
Short circuit isolators in each detector increase
system integrity and cost savings. If a short occurs in
the loop, all the devices continue to function.
Flexible Addressing and Programming Options
Installers can use rotary switches to set addresses or
program-specific options on the detectors.
Using the control panel, installers can centrally
program all device configurations. Additionally, all the
detectors on the loop are automatically identified and
shown on the control panel.
Cloak and Camouflage Detection Technology
Cloak and Camouflage Detection Technology (C2DT)
maximizes catch performance against intruders
attempting to cover their infrared signal.
