1 System planning
The BR100 Microwave Detection Sensor is designed for outdoor perimeter intrusion detection.
BR100 consists of a microwave transmitter unit and receiver unit, which detect motion in a defined
area (see Figure 1). The transmitter emits microwave energy, which the receiver constantly
monitors. Any motion in the detection zone causes a variation in the received signal. The signal
variations are processed by the receiver, which declares a sensor alarm when the received signal
meets the criteria for a valid target.
Site design
To achieve the narrowest detection zone with the highest probability of detection (Pd) the BR100
requires a straight, flat, detection zone free of obstacles and depressions. The zone must be
completely free of standing and running water. The minimum distance between the beam
centerline and any object (fences, buildings, vehicles, trees, bushes, shrubs, etc.) is outlined in
Table 1. These numbers are typical conditions and can vary depending on site conditions including
zone length, unit mounting height, ground cover, type of obstacle and its mobility, etc. The
following separation distances are the minimum requirements. Increase the separation distance
between the beam centerline and any objects whenever possible.

Zone conditions
The detection sensitivity of each zone depends on several factors:
• the required level of security
• an acceptable nuisance alarm rate (NAR)
• microwave unit alignment
• the ground conditions
• physical constraints (terrain, trees, fences, buildings, etc.)
• available space for the detection zone
For the highest level of detection sensitivity and the narrowest beam-width, the terrain must be
level to grade ± 7.5 cm (3 in.) and the surface must be free of vegetation and either paved, or
covered with a 10 cm (4 in.) layer of crushed stone (2 cm {0.75 in.} max.). (At ranges up to 100 m
the BR100 shall detect a 35 kg (77 lb) human walking, running, hands and knees crawling, prone
crawling, rolling, or jumping.)
For mid-level detection sensitivity the terrain must be level to grade ± 15 cm (6 in.) and the surface
must be paved, or covered with crushed stone, or hard packed dirt or clay, or closely mowed
grass. (At ranges up to 100 m the BR100 will detect a 35 kg (77 lb) human walking, running, hands
and knees crawling or jumping.)
For low level detection sensitivity (beam break alarm) the terrain must be level to grade ± 23 cm
(9 in.) and the surface must be paved, or covered with crushed stone, or hard packed dirt or clay,
or closely mowed grass. (At ranges up to 100 m the BR100 will detect a 35 kg (77 lb) human
walking, running or jumping.)
Zone height
The height of the microwave field at midspan is approximately equal to the minimum required
clearance between the beam centerline and an object (see Table 1) plus the unit mounting height.
There are two recommended mounting heights for the BR100: 55 cm (22 in.) and 95 cm (37 in.).
(e.g., for a microwave pair with a unit separation of 50 m and a mounting height of 55 cm the zone
height is approximately 1 m + 0.55 m = 1.55 m or 5.1 ft.). For applications that require additional
zone height it is possible to stack two, or three BR100 units on one mounting post. Table 2
provides approximate zone height comparisons between single stack and double stack
configurations. Figure 2 illustrates a double stacked BR100 configuration.
Note Certain obstacles with large cross sections such as loose fences
and large sheets of metal (e.g., a tractor trailer) require additional
clearance. For this kind of obstacle, double the recommended
separation distance.
Tx/Rx separation configuration approximate zone height
50 m (164 ft.) single stack 1.55 m (5.1 ft.)
double stack 1.95 m (6.4 ft.)
100 m (328 ft.) single stack 2.55 m (8.4 ft.)
double stack 2.95 m (9.7 ft.)
Table 2 Extended zone height examples

BR100 Product Guide Page 7
Mounting angle
For microwave pairs with a unit separation of 50 m or less, the microwave units are mounted with
a 5º pitch (toward the ground). This provides the optimum signal strength, when combining the
direct signal and the reflected signal at the receiver unit (see Figure 6).
Microwave offsets
The areas immediately above and below the transmitter and receiver antennas are not exposed to
the microwave energy. The microwave offset area describes the distance from the unit’s mounting
position to the point where the beam reaches the ground. For a mounting height of 55 cm, the
coverage is effectively right up to the mounting post. For a 95 cm mounting height there is an
approximate offset area of 1.35 m (4.4 ft.). Only partial coverage is provided in the offset area. Full
coverage begins where the offset area ends (see Figure 3). The offset distances in the example
drawings are based on a mounting height of 95 cm (37 in.). As the mounting height increases, the
offset increases. Different types of offsets are shown in Figure 4.

Power requirements
The BR100 sensor (transmitter and receiver) consumes 2 W (nominal). Both the transmitter and
receiver can operate on a wide range of input voltages (12 to 48 VDC). The required gauge of the
power cable depends on the power supply capacity, the number of BR100 units being powered
and the lengths of the power cable runs. In locations where AC power may not be stable or
reliable, an uninterruptable power supply (UPS) is recommended for primary power.
Power over Ethernet
Both the transmitter and receiver units can receive power over Ethernet (PoE). Silver Network
based BR100 pairs have the option of using Ethernet communications. To use this powering
option requires a PoE class 3 switch that is located within 100 m (328 ft.) of the transmitter/
receiver, and minimum Category 5 shielded network cable.
Figure 4 Offset arrangement examples
CAUTION Senstar strongly recommends the use of external lightning protection
devices for all outdoor cable runs (i.e., power, I/O, Ethernet, RS-422).
Note Senstar recommends using a fully managed PoE switch to supply
power to the BR100 transmitter/receiver.

Alarm data communications
BR100 alarm data communications can be provided in two ways, via relays in Local control mode
and over the Silver Network in Remote control mode. Each BR100 unit (transmitter and receiver)
has two user-configurable relay outputs and one input. The relay contacts are held in the closed
position during normal operation and open to signal an event, or if power is lost.
Local control mode
In Local control mode, the receiver’s two outputs can be configured to signal Microwave Alarm,
Input Power Fail, Enclosure Tamper, Hardware Faults and Fail Safe (system fail). A momentary
switch input to the unit’s Aux input is used to activate an electronic self-test of the transmitter/
receiver unit. Figure 5 shows the selectable input/output (I/O) parameters for Local control mode.
Remote control mode
In Remote control mode, alarm and supervision data is carried over the network cables and each
unit’s two relays are available as output control points for the security management system (SMS).
The supervised input on each unit can be used to report the status of an auxiliary security device
to the SMS. In Remote control mode, a self-test is initiated by a command from the SMS. To
communicate on the Silver Network requires either RS-422 or Ethernet (PoE) cable.
CAUTION Input Power Fail, and Fail Safe conditions indicate that the BR100
sensor is not operational.
Figure 5 Local control mode I/O configuration parameters
Note You can setup a Silver Network to enable calibration, maintenance
and diagnostic access to your BR100 units from a central control
facility, and select Local control mode to use the receiver’s two
relay outputs to signal alarm and supervision conditions.

Relay contact ratings
The solid state relays are Form A (N.O.) rated for 60 V @ 100 mA maximum, non-inductive load.
In Remote control mode, you can configure the relays as steady ON, flash mode (ON-OFF-ON-
OFF, etc.), or pulse mode (ON for a period, then OFF). For flash and pulse modes, the relay
Active/Inactive times are selectable. In Local control mode the relays remain active for the event’s
duration or for the selectable Hold Time, whichever is longer. The relay contacts are held in the
closed position during normal operation and open to signal an event, or if power is lost.
Silver Network specifications
• Data rate - fixed 57.6 k bps
• Maximum 60 devices spread over up to 4 independent network loops
• Two communication Channels (Side A, Side B)
• Response time - 1 second, or less from alarm source to Network Manager (per loop)
• Network termination - not required
• Transmission media/maximum separation distances between sensors:
• RS-422 copper wire - 1.2 km (0.75 mi.) - 2 pairs per Channel
• Ethernet - Category 5 shielded cable, 100 m between PoE switch and microwave unit
Cable ports
Each BR100 unit includes a single 22 mm (0.875 in.) cable port fitted with a compression gland,
and two provisional rear entry cable ports (requires removal of circuit card and drilling the plastic
enclosure at the locations identified with alignment marks). The compression gland is for cable
sizes 4.3 mm to 11.4 mm (0.17 in. to 0.45 in.). If required, the enclosure can be fitted with 13 mm
(1/2 in.) conduit (not included) in place of the compression gland.
Mounting posts/surfaces
The BR100 units mount easily on posts with an outside diameter ranging between 4.8 cm and
11.4 cm (1.875 in. and 4.5 in.). The posts must be plumb, firmly set in the ground, and unable to
rotate or move. For areas where the ground freezes, the posts must be protected against potential
frost heaving. A 2.5 m (8 ft.) post is generally used with 1 m (3.3 ft.) of the post buried in a concrete
footing. Figure 6 is an illustration of a post-mounted BR100 unit.
Note Senstar recommends hiring a local fencing contractor to install the
BR100 mounting posts.
Consult the local building code for information on installing mounting

Surface-mount applications
The post-mount bracket can also be used to mount a BR100 unit on a fixed stable surface. If you
are considering a surface mount application, the transmitter receiver alignment must be carefully
planned, as the mounting bracket cannot be easily adjusted in the horizontal plane for surface
mount applications. The hardware required for fastening the bracket to the surface is not included.
Figure 7 illustrates a surface mounted BR100 unit.

BR100 alarm reporting
The BR100 system reports a sensor alarm when a target disturbs the microwave field. If a large
target (e.g., a vehicle) enters the microwave field and blocks the beam, the BR100 sensor goes
into alarm and continues the alarm until the object leaves the field. If the calibration parameters
are outside the valid range at startup, or during operation, the BR100 system goes into constant
alarm until the calibration problem is corrected. The receiver unit also signals an alarm if it does
not see the transmitter on startup.
The transmitter and receiver units are housed in weatherproof enclosures. Each enclosure
contains electronic circuitry and an antenna. Both units include tamper switches and can be
configured to report enclosure tamper alarms.
Fast Alarm Response
The BR100 receiver includes a Fast Response channel that bypasses the sensor’s advanced
signal processing algorithms when enabled. This causes the BR100 receiver to function like a
classic analog microwave sensor. With Fast Response enabled, BR100 will trigger an alarm as
soon as the microwave signal exceeds the Threshold setting. The Fast Response channel
provides early alarm notification, but can also cause an increase in the nuisance alarm rate (NAR).
Fast Response is intended for use in high-security applications that include a sterile zone.
However, Fast Response should NOT be used in Sally Port areas.
Automatic gain control
The BR100 microwave sensor employs automatic gain control (AGC) to ensure the received
signal remains at an optimal level. If the receiver detects an increase, or attenuation of the
transmitted signal the AGC gradually adjusts the signal gain to maintain proper detection.
Note If the BR100 signal is blocked continuously for a period that
exceeds 30 seconds, the system may be prone to nuisance alarms
or have a reduced probability of detection for 30 seconds after the
blocking object leaves the microwave field.

2 Installation
The cover on each BR100 unit enclosure is secured with two captive screws that are factory
installed to a finger-tight torque specification. There are no user-serviceable components inside
the compartment. The cover should only be removed:
• to access the circuit card assembly for setup and calibration purposes (via a UCM connection)
• to make the wiring connections
• if the unit will be fitted with conduit
• if the provisional rear entry ports are required
To access the circuit card assembly, remove the two screws on the enclosure cover. When
replacing the cover, tighten the screws until finger-tight. Do not over-tighten the screws.
The BR100 transmitter and receiver units are almost identical, with no visual difference in circuitry.
Each unit is identified by labels on the enclosure and the PCB. Figure 8 shows a BR100 receiver
and illustrates the unit’s features. The receiver’s diagnostic activity LEDs are listed in Table 3.

Mounting the BR100 units
Mount the transmitter and receiver units on their respective posts using the hardware provided.
The mounting height of the transmitter and receiver units is measured from the top of the mounting
bracket to the ground’s surface. The initial recommended mounting height is either 55 cm (22 in.)
or 95 cm (37 in.). The BR100 units can also be mounted on a wall or other flat stable surface. Both
the transmitter and receiver units must be mounted at the same height above ground. During
mounting, the two units must be aligned to point directly at each other.
Mounting angle
For microwave pairs that are separated by 50 m (164 ft.) or less, adjust each BR100 unit to have a
5º pitch (toward the ground). The 5º pitch combines the reflected signal and the direct signal to
create the strongest received signal possible for short range applications. The calibration testing
will determine if the mounting angle is correct for your installation.

Post-mounting procedure
1. Pass the gear clamp through the slots in the mounting bracket.
2. Tighten the mounting bracket assembly on the BR100 unit.
3. On the mounting post, measure the mounting height of the BR100 unit and mark the post at
that point.
4. Wrap the gear clamp around the post and tighten until snug against the post so that the BR100
unit is at the correct height (top of mounting bracket is at the measured mark).
5. Aim the BR100 unit at the second mounting post, and using an 8 mm (5/16 in.) nut driver or
socket, finish tightening the gear clamp with the BR100 unit at the specified height.
6. Verify the mounting height.
7. For BR100 units that are separated by 50 m or less, adjust the pitch of each unit to a 5º angle
toward the ground.
8. Repeat for the second BR100 unit.
Initial post-mount alignment
For optimal performance, ensure that the BR100 transmitter and receiver are aimed directly at
each other, and that the mounting height is correct for both units.
1. Verify the mounting height of each unit (ground to top of mounting bracket).
2. If required, loosen the transmitter’s gear clamp slightly, and then carefully aim the transmitter
directly at the receiver.
3. Tighten the transmitter’s gear clamp.
4. If required, loosen the receiver’s gear clamp slightly, and then carefully aim the receiver
directly at the transmitter.
5. Tighten the receiver’s gear clamp.
6. If required, loosen the bolts that attach the mounting bracket and tilt the units (in the vertical
axis) toward each other. Re-tighten the bolts.
7. For BR100 units that are separated by 50 m or less, adjust the pitch of each unit to a 5º angle
toward the ground.
Surface mounting
The BR100 mounting bracket can be used to surface mount the transmitter and/or receiver. The
mounting bracket is removed from the unit and is attached to the surface. The microwave unit is
then reattached to the mounting bracket. Customer-supplied hardware (7 mm, 1/4 in.) is used to
attach the assembly to the mounting surface.
Note The UCM includes a received signal strength indicator (RSSI)
which serves as an aid during final alignment.
CAUTION For surface mount applications, the two mounting surfaces
must face toward each other. Surface mounted BR100 units
cannot be rotated in the horizontal axis. If required, use shims
to adjust the horizontal alignment of surface mounted units.

Page 16 BR100 Product Guide
Surface mounting procedure
1. Measure the mounting height of the unit from the ground and mark the surface at that point.
2. Using an 11 mm (7/16 in.) wrench, remove the hardware attaching the mounting bracket to the
unit.
3. Hold the mounting bracket against the mounting surface so the top of the bracket is level with
the mounting height mark and then mark the two holes on the mounting surface.
4. Drill two holes in the mounting surface.
5. Attach the mounting bracket to the surface using appropriate fasteners.
6. Measure and verify the mounting height.
7. Re-attach the BR100 unit to the mounting bracket.
8. Mount the second BR100 unit.
Initial surface-mount alignment
To ensure optimal performance, it is critical that the BR100 transmitter and receiver are aimed
directly toward each other, and that the mounting height is correct for both units.
1. Verify the mounting height of each unit.
2. If required, loosen the mounting hardware on the post collars, and use shims so that the
BR100 transmitter and receiver point directly at each other (horizontal adjustment).
3. Tighten the mounting hardware.
4. If required, loosen the bolts attaching the mounting bracket and aim the units toward each
other (in the vertical axis). Re-tighten the bolts.

Transmitter/receiver wiring connections
The BR100 wiring connections are made on 45º spring terminal blocks. The spring terminals
accept wire sizes from 16 to 24 AWG with a 9 mm (0.35 in.) strip length. The DC power input is
made on T4 and the input/output (I/O) connections are made on T4 and T5. Each unit’s auxiliary
(AUX) input is available when using Remote control mode (network alarm data communications).
The self-test input is available in Local control mode (relay output alarm signaling).
T4 - power input
The BR100 units require 12 to 48 VDC to operate. Connect DC power to T4 pin 1 (-VDC) and
T4-2 (+VDC) or use PoE (T9).
T4, T5 - input/outputs
T5 connects to output 1 and output 2, and T4 connects to the auxiliary (AUX) or self-test input (see
Figure 12 for connection details).
In Local control mode, the two outputs can be configured via the UCM to report user-specified
alarm and supervision conditions (see Alarm data communications on page 9). A momentary
switch input to the self-test input activates an electronic test. Self-test activation requires a
normally open, unsupervised momentary switch input. The momentary switch input must be
closed for a minimum of the time specified in the Filter Window parameter (via the UCM). See
Table 4 for example input wiring diagrams and supervision resistor values.
In Remote control mode, the two outputs are used by the security management system (SMS) as
output control points. The AUX input is available to report the status of an auxiliary security device
to the SMS. The input’s status is determined via an internal reference voltage, and the
configuration of the contact closures and supervision resistors. Any change in the input’s status is
reported to the SMS.

Relay contact ratings
The solid state relays are Form A (N.O.) rated for 60 V @ 100 mA maximum, non-inductive load.
The relay contacts are held in the closed position during normal operation and open to signal an
event, or if power is lost.
Cable ports
Each BR100 unit includes one 22 mm (0.875 in.) cable port fitted with a compression gland. Pull
the cables through the compression gland, into the enclosure and through the locking nut. Then
install the compression gland in the cable port. After making the wiring connections, tighten the
compression gland to provide weather protection and strain relief.
Alternatively, there are two provisional cable entry ports that are indicated on the back of the unit.
To use the provisional ports you must remove the unit’s circuit card assembly (CCA) and drill the
holes in the plastic enclosure. The cable glands or conduit fittings required for the rear ports are
customer supplied.
Making the I/O wiring connections
1. Pull the data cable into the enclosure.
2. Prepare the data cable leads - strip length = 9 mm (0.35 in.).
3. Make the wiring connections on the appropriate terminals (see Figure 12).
Enclosure tamper switch
Each BR100 unit includes a tamper switch to indicate if the enclosure cover is removed
(closed = secure, open = tamper).
Power supply connection
When a central low voltage power supply is being used for primary power, it should be powered
from an uninterruptible power source.
• To power the system from a central source, run the power distribution cable around the
perimeter and tap off to each BR100 unit.
• In a weatherproof junction box near each BR100 unit, splice the power cable to a lighter gauge
pigtail. Connect the negative lead to T4-1 (-) and connect the positive lead to T4-2 (+) (see
Figure 12).
Local power supply
To use a local DC power supply, the power supply must be outdoor rated and installed in its own
weatherproof enclosure. The local power supply can be mounted on the same post as the BR100
unit to keep the wire run to a minimum. Connect the negative lead to T4-1 (-) and connect the
positive lead to T4-2 (+) (see Figure 12).
Note The contact closure input to the AUX input must be voltage-free.
WARNING! DO NOT bring AC mains power into the BR100 enclosure. If a local
power supply is being used, it must be installed in its own
weatherproof enclosure. Consult the local electrical code for
information about the connection of AC mains to your power supply.

BR100 Product Guide Page 19
Power over Ethernet
For power over Ethernet, a fully managed class 3 PoE switch is recommended. In this
configuration, minimum Category 5 shielded Ethernet cable is also required and the maximum
distance between the BR100 transmitter/receiver and the PoE switch is 100 m (328 ft.). To use
PoE, connect the PoE switch to the Ethernet port on the CCA.
