Expand Break Beam Security With Additional Sensors

Expand your break bream perimeter security by connecting additional break beam transmitters to your break beam receiver with the Dakota Alert 4000 Wireless Break Beam Transmitters (Pair). This pair of point to point infrared sensors create an infrared cross beam and detects any intruder that passes through the beam area. When a beam is broken, the sensors signal the receiver to alert you, helping you keep your home safe and secure. The infrared sensing terminals can be mounted up to 300 feet apart and send a signal back to the receiver up to a mile away anytime someone passes between the sensors.

  • Up to 300 foot operating range
  • Sends signals to a Dakota Alert 4000 receiver up to a mile away
  • Solar panels conserve and recycle power
  • Detection immunity to small animals and objects reduces false alarms

Installation Details

The Dakota Alert 4000 Wireless Break Beam Transmitters (Pair) are a solar powered wireless infrared break beam sensor that is simple to install and requires no wiring. The break beam transmitters are powered by lithium ion batteries that are recharged through the solar panels during the day. The sensors are not affected by small objects such as falling leaves or birds. The beam sensor is ideal for outdoor applications such as storage lots, lumber yards, car dealerships, etc. Multiple sensor pairs can be used to send a signal to one receiver if you wish to set up a perimeter.
