The BBT-2500 dual beam sensor from Dakota Alert features a solar powered dual beam detector with built-in rechargeable batteries. When both beams are broken a wireless alarm signal is sent up to 2500 feet to the chime receiver. The BBT-2500 system operates on the same frequency as all Dakota Alert 2500 products. This means you can expand your existing Dakota Alert system with the new photo beam sensors. The BBT-2500 wireless beam sensors come complete with a solar panel and built-in rechargeable batteries so you'll never need to worry about changing batteries again!
The incredible 2500 foot wireless range allows these units to be placed almost half a mile away from the receiver. Popular as both driveway alarms and perimeter alarms the beam sensor units can be placed up to 300 feet apart allowing a large monitoring area plus they use a dual beam system helping to greatly reduce any false alarms as BOTH beams need to be broken for an alarm to be triggered.
