I had to jump voltage from the power terminal to the com terminal on the NO screw. On the output screw I then ran the wire to my buzzer and then ground on the buzzer went back to the ground terminal of the Seco device.
The laser makes it really easy to align. Also the reason I installed this is I kept getting false alarms from the motion detection alarm from my security camera DVR. Another had many false alarms on another driveway defender motion detector system. With this photo beam detector so far there has been no false alarms. I just wish Seco alarm had designed this is a self contained unit that does not need to be connected to an existing Security system which wold include the buzzer with volume control.
I bought more. The signal level, which began to slowly drop off about two years ago, just recently took a huge dive and now the detectors are constantly giving false trips. No amount of alignment will provide enough signal, but I must say, these things have taken a beating outdoors, and I am not disappointed at all.
In fact, I just installed a new set in place of the old. The following is my original review: I've had these up and running for about a week now, at 55 feet of separation. I haven't had a single false nor do I know of them ever missing. We've had some pretty heavy rain and I expected them to false at least once, but they never did. The adjustable trigger timing is very nice, and the alarm LED makes testing a breeze.
Setup was a piece of cake with the laser alignment and I had both the transmitter and receiver dialed in in less than fifteen minutes. The screw terminals made the connections easy and reliable, and they are clearly labeled. To make them more inconspicuous, I wish the housing had a less reflective surface, and I wish there was an option to turn off the LED indicators.
The latter was remedied with a piece of electrical tape. Regardless, excellent product. I am very impressed. These things just plain work. This past winter we had one of the heaviest snowfalls we've had in 20 years and I was certain these sensors would false, but they never did. I couldn't believe it! We've had single digit temperatures, torrential rains, and degree summer days and through it all, these sensors never fail to detect and they never false. If the alarm sounds, rest assured, something has passed through the beam.
This is one of the most reliable, rock solid products I've bought in a long time and so easy to use. I am more impressed now than I was when I wrote my initial review above. It turned out to be an alignment problem. But my sensors are mounted to wooden fence posts stuck out in the woods. After two years of weathering, the posts have warped a bit.
I realigned the sensors and they are back to being as rock solid as ever. Once again, I can rest assured that if the sensors trip, something has passed through the beam.
Great product. These are good but the only thing the switches on these work montairly if you use it for a burglar alarm it needs to have time delays relays added to. Because it just cuts on and off very fast. Great maybe for driveway or something like that. Lots of options for open or closed contacts. Easily mounts and comes with extra hardware to mount on multiple surfaces. Be sure to mount high enough off the ground as to not get false alarms from neighborhood cats or other animals. The built in laser made it super quick and easy to align the units.
Should come with power supply and give options for add ons for simplicity. Bought my 3rd set of these so I had to write a review. During the day, they are noticeable, but most of the thieves wander at night and have no clue they are mounted. I would submit an image but its not giving me the option to do so. Go to Amazon.
