Wireless system - The Dakota Alert BBT-2500 doesn't require any wiring as it employs an active Infrared beam to detect any large object that passes through the beam area
Expandable - Add more BBT-2500 transmitters to your Break Beam System if you intend to monitor a larger perimeter like storage yards. Each beam can be spread up to 300-ft apart
Prevents false alarm reports - The built-in sensors only detect large animals or objects that broke into the beam area. It has detection immunity against small objects like falling leaves
Sends signals for up to 2500-ft - Even if your BBT-2500 is 1/2 mile (2500-ft) away from the DCR-2500 receiver, the latter can still pick up the alert signals when someone passes between the sensors
Recharges easily - The BBT-2500 is powered by lithium-ion batteries and can be recharged through the solar panels. Now, you don't need to worry about the sensors failing throughout the day
Dakota Alert BBT-2500 Wireless Infrared Break Beam Alarm SystemThe Dakota Alert BBT-2500 Break Beam Alarm System includes two sensors: a transmitter and receiver. The wireless transmitter uses an active infrared cross beam. Whenever a large object (e.g., person or bear) breaks into both beams, the BBT-2500 sends a warning automatically to a Dakota Alert 2500 Series Receiver.You can get an instant report if there are any intruders in your backyard. The BBT-2500 has four different alert tones that indicate which sensor was activated. You can also add more BBT-2500 transmitters to one receiver if you're monitoring a large perimeter such as car dealership, commercial parking lots, and storage yards.What makes the BBT-2500 stand out from other alert systems is its onboard solar panels. The solar panels in the sensors conserve and recycle power. You're at ease that the sensors won't fail throughout the day.Note: Additional sensors are sold separately. Please DO NOT install the BBT-2500 with a different infrared detector model as it may cause a false alarm.TECHNICAL SPECS:Detection Type: Infrared Break BeamWireless Frequency: 434 MHzCode Combinations: 256Wireless Range (from Sensors to DCR-2500 Receiver): Up to 1/2 Mile or 2500-ftDetection Range: 300-footZones: 4Types of Alert Tunes: Classical, Westminster, Ding Dong, WhistlePower Source: Solar Panels, Rechargeable Lithium-Ion BatteryOperating Temperature: 30~120 degrees FahrenheitDimensions: 13.3 x 3.3 x 2.0"
