What is a Wireless Break Beam Sensor Alert Kit?
The BALERT entrance alert kit has been around for as long as I can remember. It’s a top-rated product because it’s a simple but effective way to monitor a door or hallway. In many cases, customers who liked the functionality of the BALERT didn’t purchase the product because it was wired…from the emitter box to the speaker.
Now, we have a wireless version of the BALERT, the BALERT-W (“W” for Wireless) is the Seco-Larm E-931CS22RFCQ. You get the same reliability as the photo beam reflector-based product with the added benefit of a wireless transmission from the emitter to the speaker.
Here’s how this break beam sensor-based kit works:
The BALERT-W is the Seco-Larm E-931CS22RFCQ. The kit comes with three (3) main components: a sensor that emits an invisible beam to a reflector, a reflector, and a wireless speaker. To understand how the product works, we will use a typical doorway as the area we want to monitor. On one side of the door, we will mount the wireless sensor (plugs into a standard wall outlet); on the other side, we will mount the reflector. The sensor will send an invisible beam to the reflector. The system is silent as long as that beam is reflected in the sensor. When that beam is broken, which means the beam has not reflected the sensor, the sensor is triggered, and it then sends a wireless signal to the speaker (the speaker plugs into a standard wall outlet).

Break Beam Kit Features:
- Waterproof reflective sensor (transmitter)
- Wireless Speaker
- Reflector
- Two power adapters (one for the sensor, one for the speaker)
- Three mounting brackets
- An optional Wall Mount Bracket is available for separate purchase
Here’s what’s in the BALERT-W (Seco-Larm E-931CS22RFCQ) Kit:
- The maximum distance from the sensor to the reflector is 22 ft.
- The wireless range, from the sensor to the speaker, is “up to” 328 ft. (100 m). Please note this is a line-of-sight range. Building materials will interfere and possibly reduce the range.
- Included plug-in transformers power the speaker and sensor
- Adjustable volume on speaker up to 90 dB
- Sensor and reflector are outdoor rated 32 F – 122 F
- The sensor can pair with an unlimited number of speakers
- The speaker can pair with up to 5 sensors
- The speaker will make a chime or ALARM sound
- The alarm output duration is 3-30 seconds
We would also recommend two other choices:
- The ERA-PIR-SPK kit is a passive infrared sensor typically mounted over the door. When a visitor passes through the zone, the speaker inside the sensor plays a chime sound.
- The EZ CHIME – a purely mechanical entrance alert.

Finally found one that works every time unlike the cheap electronic ones.

Easy setup. Good price. Fast shipping. Asked company about not able to order Solar charger from them. Did not get response.
Billie Jo Patraw –
It was exactly what we were looking for! Easy to install and works great!
John Sherman –
Every thing was a great experience..thank you
Brad Wagner –
Product arrived quickly and was a fairly easy installation. Works great so far.
One thing I’d like to add is to have the ability to cant the reflector to allow for a diagonal beam.
Otherwise I would recommend this product and order it again.
Stacey Howell –
This was purchased for the front door of our 1500’ sqft shop that is usually open. Works great The speaker was placed in the back work area. Chime is loud and clear to alert when someone walks in. Perfect for our needs!
Greg Mahan –
We had a 20+ years door buzzer & it finally quite working.
This new product is 1/10 the size & with a remote speaker we mounted in the rear room. GREAT PRODUCT…
5 STAR’S

This wireless reflector works well, and is nice that it will only notify you once when people are standing in the way instead of continuing to go off. Only think it seems maybe a bit sensitive to reflective light, so we might get a “cover” to try to shield it and see if that works.

We have a little cat shelter in a busy shopping mall. Now, when working in the back area, we can hear when our customers come in. Couldn’t be happier!
Larry Yeatts –
Will the wireless speaker pick up the signal through a block wall 65 feet away from the beam alert .If not will the wired system expand to 85 feet .
Huskers –
What temperature is the speaker rated for? I see the sensor and reflector are rated for 32-122 degrees Fahrenheit.
Randall Tullier –
I bought this unit but itâs not load enough can you give me a extra loud speaker to plug into the outport
Dustin Pecora –
Iâd like to purchase this kit, but would need a second sensor to link to the same speaker. I see options to add on additional speakers, but not additional beam and reflector. How would I go about ordering a kit with two beams, two reflectors and one speaker?

The wireless speaker keeps the beeping away from the incoming customer and close to where the sales people are.
