Description
Solar-Powered Break Beam Sensors with 1-Month Standby Time for Recharging 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.

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 (the duration is set on the 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.
What’s Included with the SSB-4000 Beam Sensors?
- 2 x SSB-4000 break beam sensor pair (A & B sensor).
- Mounting screws, nuts, washers
- Metal pipe mounts
- Pipe mount rubber adaptors
- “C” mounting brackets
- User guide
What You’ll Need
- A compatible Dakota Alert 4000 series receiver
- Phillips head screwdriver and 7mm or an adjustable wrench for mounting
- USB micro charger (not mandatory)








joel jones –
how can I get this unit to alert me via TXT or phone call??
Customer –
1. How does snow and ice affect the sensors? 2. Where is the solar receiver located on the sensor – back, front, top?
3. Can the sensors be mounted tight to a brick column and will the solar receiver still work?
Mary A Coletti –
Can you program for the alarm to last for 5 seconds or will it sound the alarm until you turn it off?
Thomas Clarke –
Hi, I am looking for a simple alert for the front door of our business. I would like to surface mount a beam on the inside of the door jams which would trigger a remote bell/alert in our production area.
Bruce Bierman –
If this never receives direct sunlight but receives a full day of outdoor shaded light (some of which is reflected off of houses across the street), will that be enough light to keep the batteries charged? It will likely be “tripped” less than once or twice a day on average, unless a delivered package is left in the beam.

Why isnât my receiver going off when the beams are broken
