Seco-Larm E-931-S35RRQ Enforcer Indoor/Outdoor Wall Mounted Photoelectric Beam Sensor with 35 Foot Range

Tested it indoors at up to 16m and it was working reliably, I ran out of more distance to test. But in the end I installed it for my swinging gate outdoors which is only about 6m and it was a breeze. Saved me from the hassle of replacing the old sensor’s batteries every few weeks.I have to say the reflector is pretty small (about the size of 3 fingers) so aiming is challenging but not too hard. Power the sensor, hold the reflector in your hand right in front of it, then slowly move to the other side while making the necessary adjustments and it should be fairly easy and quick.

Wired this into my konnected smart alarm to notify me when the pizza guy walked up the drive. I love it. No more surprises. If the cops come up the drive I have time to hit the back door and over the fence before they realize I'm gone.

bought this wire https://a.co/d/fwDGndn, wire the device wires brown+white wire to cable red,blue device wire to black wire of cable, gray wire device to yellow cable wire, at the other end,(1) 12vdc electronics relay, one 12vdc power pack, wire 12+ to red, common ground, ground right side of coil, yellow to left side if coil,for ardrino input, 5v to 300 or greater resister the other side of resister goes to common side of relay contacts, ground the other side of contacts, the just set homeseer event to change on open of input,mount the reflector about 4' form ground, turn trimmer up all the way, have someone watch for the yellow led to come on (do not block the unit) as you move the reflector, then just mount the reflector in the spot it turned yellow led on and you are done

very relaybole, working for the past two years with no issues

The bright ness and the quality is top notch

The unit was bought as a direct replacement for an existing one, operating a motorized exterior door, since it was installed without a protection from the rain, preventing water could go through the adjusting screw and the adjustment access upwards, instead of protecting it through a sideways installation. There is a factory installed o-ring preventing water from damaging the unit, but it doesn't guarantee a full water ingress. Therefore, a cover has been added to the replacement, protecting it against rain and extending its useful life. Complete installation instructions make the installation fairly easy. Other than this inconvenience, it works as intended.

The wiring is different for all models, but a brief google search will help you figure it out. I have a co-z opener and found instructions quickly.

zero mounting instructions, had to mirror the replacement. However if it was a new install I would have been stuck. Once mounted and hooked up it worked well. Took about 15 minutes for process.
