BBT-2500
Break Beam Transmitter
User Guide
PRODUCT DESCRIPTION:
The BBT-2500 is used with the DCR-2500 receiver. The BBT-2500 uses Active Infrared to detect anything that
passes through the sensor pair and breaks both beams at the same time. When the beams are broken, the
unit sends a signal to the receiver. This will sound one of four different tones (Classical, Westminster Chime,
Ding Dong, or Whistle). The BBT-2500 can be used to monitor access into any area, from your backyard to
lumber yard and everything in between.

READ MANUAL THOROUGHLY BEFORE INSTALLATION. RETAIN MANUAL FOR
FUTURE REFERENCE. FAILURE TO FOLLOW DIRECTIONS PROPERLY MAY RESULT
IN DAMAGE.
ONLY use this product for the detection of moving objects such as people and vehicles.
DO NOT disassemble or attempt to repair the product.
DO NOT install this unit with any other infrared detector. It may cause false alarms.
DO clean and inspect the unit regularly for proper use. If any problem is found, contact Dakota Alert, Inc.
WARNINGS:
This device complies with Part 15 of the FCC rules, Operation of this device is subject to the following
conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference,
including interference that may cause undesired operation.
HARDWARE INSTALLATION:
Verify that all installation hardware Is included. Tools needed: Phillips screwdriver, adjustable wrench.
(4) Right Angle Brackets (4) Cross Brackets (4) ‘U’ Shaped Brackets
(8) M4 nuts (8) M5x27mm screws
(8) M5x18mm screws
(16) M5 nuts
(8) M4x12mm screws

PAIRING:
To make installation easier it is recommended to pair units ‘A’ and ‘B’ before mounting.
On a flat surface push the power button (Figure 1-1) on ‘A’ then push the power button on ‘B’. Laying the
units flat on counter or table, line up the infrared light holes (Figure 1-2). The units will then pair.
You will see lights flashing during this process. Leave the units in place for one minute to make sure this
process is complete. Once paired, test them by completely blocking all 3 holes (2 infrared light holes and
indicator hole shown in Figure 1-3). Unit should send a signal to the DCR-2500 and sound an alert. Unit
will only alert if all 3 holes are completely blocked for at least 100ms. If an object passes through the beam
faster than that it will not be detected. ‘A’ unit contains the radio transmitter module.
The ‘A’ unit transmitter module is factory set to match the zone 2 setting of the DCR-2500. It is not
recommended to change the code setting unless it is needed to avoid interference or a different zone is
desired. Be careful when opening this unit to avoid damaging any internal components or wires.
‘B’ unit contains no user serviceable parts. It is not recommended to open this unit.

CIRCULAR POST MOUNTING:
1. Take the right angle bracket (Figure 3-1) and attach the
cross bracket using (2) M4 nuts and (2) M4x12mm
screws. Repeat for all brackets.
2. Using (2) M5 nuts and (2) M5x18mm screws attach right
angle bracket (Figure 3-2) to units ‘A’ and ‘B’.
3. Attach to post with ‘U’ shaped bracket (Figure 3-3).
Using (2) M5 nuts and (2) M5x27mm screws attach ‘U’
bracket around post. Tighten securely.
FLAT SURFACE MOUNTING:
1). Using (2) M5 nuts and (2) M5x18mm screws attach right angle
bracket (Figure 4) to units ‘A’ and ‘B’.
2). Use screws that are appropriate for your material and surface
(not included) and mount right angle bracket taking care to keep
units ‘A’ and ‘B’ level.
MOUNTING OUTSIDE:
Units ‘A’ and ‘B’ can be mounted up to 100 metres apart.
Determine height and location you would like to mount the unit.
Recommended height is 1 metre’. There must be line of sight
between ‘A’ and ‘B’. Units must be mounted level. Install the unit
on a stable surface. Do not install where trees or other objects can
block the beam. Mounting 1 metre will avoid false alerts by small animals
crossing under the beam, but still detect people and vehicles.
Mount unit ‘B’ first and face the infrared holes toward where unit ‘A’ will be mounted. When mounting unit
‘A’, face the infrared holes towards unit ‘B’. When the units align the ‘A’ unit indicator light will begin to blink.
To make sure of proper alignment cover only the top two infrared holes. Unit should not alert. Then cover
only the bottom two holes, again unit should not alert. Cover all three holes and the unit should alert. If the
unit alerts with only the top two infrared holes covered, raise the unit about 25mm to correct misalignment.
If the unit alerts with only the bottom two infrared holes covered, lower the unit about 25mm. When properly
aligned, the unit will only alert when all three infrared holes are covered.
Detailed below are the two most common mounting options.

FOR ALL MOUNTING SITUATIONS:
For all mounting situations In all mounting situations it is very important that the ‘A’ unit only interact with one
‘B’ unit or the pair may not alert properly. Use the diagrams below for reference.

PERIMETER MOUNTING

ONLY OPEN UNIT ‘A’ IF CHANGING THE ZONE/CHIME IS ABSOLUTELY NECESSARY.
It is not recommended to change any settings as the BBA-2500 is factory set to match.
DO NOT OPEN UNIT ‘B’.
Remove the 8 screws on the back
of unit ‘A’ (Figure 5-1). Gently
lift the solar panel to expose the
transmitter board (Figure 5-2).
Locate the 10 dip switches on
the red block. The first eight dip
switches are for the frequency
setting (256 combinations). Set
switches 1-8 to match the eight
switches in the receiver. Switches
9 and 10 are for the zone/channel
settings on the transmitter.
The four zones are listed in the table below.
CODING THE DCR-2500 RECEIVER:
Open the receiver case by inserting a small
screwdriver into one of the pry notches on the side
of the case (refer to receiver manual). Gently lift off
the front cover. Locate the eight dip switches on the
DCR-2500 and make sure they are set identically to
dip switches 1-8 on the BBT-2500.
Note: If more than one transmitter is used with the
receiver, the first eight dip switches of all transmitters
must match the eight dip switches of the receiver.
Note: Whenever a change is made to the time jumper or the dip switches, the receiver must be
turned OFF and then back ON to operate properly.

TROUBLESHOOTING:
If sensor pair alerts when originally paired, but will not alert when mounted...
1. Push power button on unit ‘A’
2. Look in center hole for the indicator light. If light is on, proceed to step 3. If light is not on, press power
button again. Indicator light should come on.
3. Repeat steps 1 and 2 for unit ‘B’. This will re-sync the units.
If experiencing false alerts...
• Check for obstruction (i.e. branch, frost)
• Extreme fog
• Extreme snow and rain
• If obstruction/weather are not involved, try changing the frequency of the DCR-2500 and unit ‘A’
• If unit is blocked continually a second signal will be generated after one hour
If no signal...
• Turn power off on all units for 60 seconds and then turn power back on
• Make sure units are still aligned
• Make sure all 8 dip switches in DCR-2500 match the first 8 dip switches inside unit ‘A’
