 Can you guess what safety device has been installed (badly) here?

WinnerTough to stop the door from pinning little Jimmy if the beam travels a 6 inch gap rather than being placed on either side of the door. I kind of hope the guy who installed it damages his car as the door continues to close on his hood since there is effectively no safety mechanism anymore.

Don't garage doors have a pressure sensor? All the ones I've known in the past 20-30 years or so use the IR sensor, but I seem to remember in my younger days before they used IR that if you shoved something under the garage door, it would stop and open back up. edit: if pressure sensors have been replaced by IR optic sensors, I just came up with a new idea for a high output can crusher.

I think it's more of torque limiter that goes into reverse if the electric motor suddenly increases load due to something stopping the door from traveling all the way down. Regardless, I think the downforce is still enough crush pets and break little Jimmy's bones before that kicks in. That's why IR beams are mandated now.

They have both. But you SHOULD have both. Because the same kind of person who puts the light sensors like that is also going to crank the down force sensor up to "cut children in half" rather than lubing their garage door tracks.

How hard is it to actually line up those sensors across the width of a garage door? I am trying to get a sense for exactly how lazy people are being about this.

They just need to be roughly pointed at each other. I bent the metal hanger on mine once and it took maybe 15s to re bend and fix it.

Those IR sensors make for great foot-activated "whoops forgot something inside" switches.

They literally clip on to the door track, so they don't even needs to be screwed onto anything. You then roughly aim them at each other and if the LED doesn't come on you adjust from there. The hardest part is the 5 minutes you'll spend tacking the wire up on the wall/ceiling with the cable staples that come in the box with the opener.

Man that is super depressing. If it was some sort of Mission Impossible poo poo with angling mirrors or whatever I would understand people getting frustrated and trying to shortcut it to finish the job, but if its that simple and people just don't give a gently caress...  I don't know why I should be remotely surprised given everything else in this thread.

Maybe they live in some crazy plot of land where the sun is always setting? At my old house during fall I think the drat thing wouldn't close at 5-6pm when the sun was setting and blinding one of the sensors. Had to get a cardboard box to place in front of my garage door to cast a shadow on the thing and then close the door and go back outside to collect the box

Or maybe they just like hitting the garage door button and then running out of the garage under the door before it closes.

How do those sensors look when installed correctly? I've never actually seen an automatic garage door before. Mine is big heavy chunk of wood from 1951 and my opener is my wife if she's in the car.

A little black box at the bottom of the track on each side of the garage door opening, aimed at each other. There's an IR light shining out of one and a sensor in the other. If the sensor sees the light, the door is probably clear and is allowed to close. If it doesn't, it must be blocked, and the door reverses back up. e: I'm a nice guy, so I googled it. Here's an example, you'd have one on each side:

So if something is taller than the beam it gets crushed? I remember now my grandpa had an automatic door on his garage and I once closed it while his truck's bumper was sticking out. It touched the bumper then backed off, sort of like an elevator door. With the IR sensor I imagine I'd have been hosed? Some sort of pressure system seems way safer, and no false trips from running out the door.

Yeah, if you have something sort of leaning out over the beam then of course the beam won't trip. But far more common is that you have something standing on the beam path. Like Motronic said, the motor is also supposed to detect obstructions; it's a multi-step safety.

And on commercial doors you typically have a third safety: a compression strip that's part of the gasket on the bottom of the door that will trip if it hits something.

The litter is non-porous plastic, and the water gets an added dose of a enzymatic mixture and a deodorizer. Nifty kit, but drat expensive to buy and maintain.

Why do all these improperly installed sensors still have all the excess wire slack? Are they delusional enough to think that they will fix it later?  e: Or does the wire come stripped and they are too lazy to cut and strip it again?
