The Dakota Alert BBT-2500 Solar Powered Wireless Transmitters are designed for adding to your Dakota Alert BBA-2500 solar powered wireless infrared break beam system. They are extra wireless transmitters that can be used in other locations; for example, a second driveway, other buildings, backyard, etc.
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.

Pairing the BBT-2500 Units
To make installation easier it is recommended to pair units ‘A’ and ‘B’ of the BBT-2500 before mounting. On a flat surface push the power button on ‘A’ then push the power button on ‘B’. Laying the BBT-2500 units flat on counter or table, line up the infrared light holes. The BBT-2500 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. Unit should send a signal to the DCR-2500 and sound an alert. The BBT-2500 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.
The BBT-2500 units ‘A’ and ‘B’ can be mounted up to 300’ apart. Determine height and location you would like to mount the unit. Recommended height is 3-4’. 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 3-4’ 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 there is an audible click in unit ‘A’.
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 an inch to correct misalignment. If the unit alerts with only the bottom two infrared holes covered, lower the unit about an inch. When properly aligned, the unit will only alert when all three infrared holes are covered.
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.
If sensor pair alerts when originally paired, but will not alert when mounted...
1. Push power button on unit ‘A’ of the BBT-2500
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 BBT-2500 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’
