TOPENS TRF3 Safety Reflection Photocell Retro-Reflective Photoelectric Beam Sensor for Automatic Swing Sliding Gate Openers Garage Door Openers Access Control Security Alarm Systems Outdoor Use

The motion sensor light took a few tries to install, but it now works perfectly. Jessica (and the rest of the customer service team) was helpful in responding immediately with some tips and instructions to get it to work. I needed an electrician to help me install, but I'm very happy we now have this safety feature on our gate. So far so good! And MUCH less expensive than having a company come to install the system.

This product it’s very good and effective to security the gate, I used this in all my installations and very happy with this product

Had some issues with the wiring since the control box is so small and the inlet holes are not big enough to fit wiring. Other than that, pretty simple.

The media could not be loaded. Great product. Was able to set up without completely boring underneath 13 foot driveway. This reflective photocell is the way to go! My ck700 opener which is also amazing, had plenty of room in the circuit board for this upgrade.

It didn't work for me at all. Bad product

Works great. Only problem is it fogs up on the inside sometimes. This is user error, however, as I am missing a screw on the bottom.My only improvement would be that it should not stop the gate on the open cycle, otherwise, works great!

Easy installation with direction provided. This accessories is easy to line up using a string.

I would like to say that TOPENS customer support has been great and responsive. They replaced the unit with another that worked even worse. Here is the deal - the way gate openers are sold is that things like this item are options. I have a Topens CK700 sliding gate opener which works fine. I have bought several other add-on options which all work fine.However, this infrared sensor did not work as expected - the first one only worked 8 out of 10 times (the rest of the times the gate did not open - in other words the fault was intermittent). The replacement sensor did not work at all.In the end, I purchased https://www.amazon.com/gp/product/B07J6S51RC/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 which worked as advertised. Please note that I could have purchased TC102 photocell: https://www.amazon.com/dp/B07ZTB4VML which I believe would also have worked.I even built housings in case sunlight (or the infrared light on the gate camera for night vision) was the root cause of the failures.I spent about 20 hours trying to get this to work without fail. I believe the problem lies in the sensor's internal relay which informs the gate opener that the path is clear of objects. I would heed the other reviews saying this sensor does not work. Two of them did not work for me.I gave this a three star review because TOPENS has refunded the monies for this purchase. Again I am very pleased with their customer support which I the best I have ever encountered. I highly recommend TOPENS products because of their support and quality.
