Solar Powered Break Beam Sensors with 1-Month Standby Time on Recharge Batteries!

Used in conjunction with the DCR-4000, the RE-4K PLUS receiver by Dakota Alert, or the PR-4000 Portable Receiver, the SBB-4000 Break Beam Sensors are Solar Powered Break Beam Sensors that will enhance your security by providing you with a larger monitored area to fit your needs. 

SBB-4000 Break Beam Sensor Transmitters by Dakota Alert

Not to say that the two standard sensors that come with the break beam system are not good enough; they are. Right out of the box, the system can do anything you want and more.  These solar-powered break beam sensors are wireless, so installation can be done in mere minutes as no electrical wiring needs to be done.  The sensors are powered by a lithium-ion battery that will recharge in the sun and hold a charge for up to 1-month. Want to use them indoors? That’s okay, too. The sensor features a charging port for USB microcharging.

The sensors may be set at a maximum distance of 300 feet apart and used with up to 14 other sensors (a total 16).  When both beams between the sensors are broken, the sensors will send a wireless signal up to 5,000 feet away to the DCR-4000 receiver or other Dakota Alert 4,000 series receiver.

Most entrance chimes on the market today use one PIR beam per sensor to detect motion or movement.  These sensors (SBB-4000) are called “break beam” sensors.  Beams are sent between a set of sensors. When something passes between them, an alarm is triggered (only when both beams are “broken.”)  This eliminates false alarms sometimes created by falling objects like leaves, for example.  However, small animals may break both beams, so sensors in a set should be mounted off the ground, at least 3-4 feet high.

SBB-4000 Feature Highlights

  • Up to 16 sensors/transmitters may be paired to any Dakota Alert 4000 series receiver.
  • Easy setup and programming.
  • Large solar panels work in areas that don’t receive constant sunlight.
  • Rechargeable batteries power units for up to 1 month on a full charge.
  • A Micro USB port is available to charge manually for indoor use.
  • Alert notice is triggered if beams are continuously uninterrupted. For example, if something constantly breaks the beam between the two sensors, an alert will be sent every 5 or 20 seconds (duration is set on sensors).
  • Break beams prevent false alarms as they are only triggered when the beams between the sensors are broken or interrupted.
  • Included industrial hardware included for sensor mounting. It may be mounted on a flat surface, pole, pipe, or support using the “c” bracket on the back of the units.
