I hope you have good liability insurance. Automatically closing a garage door is a very bad idea. And before someone chimes in regarding some newer garage door openers which offer this feature, I suggest you read the limited liability section of the manufacturers warranty.TLGriff said:I am monitoring the relay output (Out 3) to tell when the door state changes (when the relay closes), but the message itself comes from the input (Zn 15). After 15 seconds, when the door is fully open or closed, it reads (Zn 15). If it's open, the message is "Garage overhead door is open" and if it's closed it is "Garage overhead door is closed". I'm using the [Say Closed/Open] option, so the use of "open" or "closed" is dependent on the state of the sensor on (Zn 15). We can't see the garage door from the house, so it's nice to hear whether it's open or closed, and as I said, that part works very well.
As for the automatic closure after dark, I ordered a 360º occupancy sensor to mount on the ceiling of the garage. If there is no motion in the garage for a period of time and it is dark outside, I'll have it make a couple of "Garage door open" announcements and then close the door.

You can do it safely, but you have to do it correctly. You need a sensor to determine when the door is open, and a sensor to determine when the door is closed. One sensor won't cut it.elvisimprsntr said:I hope you have good liability insurance. Automatically closing a garage door is a very bad idea.

I have already cited documented cases in this and other forums where a child was crushed to death under a garage door, even with a beam break sensor. The parents of the child sued the homeowner (the uncle), Sears, and the contractor who installed the door opener. There is also the scenario in which you park a vehicle half way in the garage and the beam passes under the vehicle. Even if the door reverses direction it will likely at least cause some damage to the vehicle.
My conscience is clear. Is yours?
It's not just about safety. It's about liability. I suggest you speak to your homeowners insurance provider if your home brew Rube Goldberg autonomous garage door contraption of sensors and programming would be covered against personal injury or property damage.ano said:You can do it safely, but you have to do it correctly.

Second, the beam sensor the garage door manufacturers provide by law is a joke. Because people usually close their garage door as they go into their house, the door IS closing unsupervised, which is very dangerous. What you need is a wall of IR beams across ever inch of garage door opening. I use one with 10 beams, but what you use will depend on your garage door.
Last you need to write some programming to stop the door should a beam be blocked. On mine, the beam sensors will even stop the door when I use the opener button to close the door, not the automation system.
There is no reason you can't make it very safe, but like anything else, its going to cost you more money to do it correctly.

I have no respect for those who attempt to automatically close their garage door. I have even less respect for those who help those who ask how.

Apparently these companies didn't get your memo on the liability. Note that ALL of these systems use the stock one IR beam which I said was inadequate.
About 7 or 8 people are killed a year by garage doors. But 450 are killed a year from just falling out of bed, and another 480 are killed falling of of ladders. 70 kids die every year chocking on hot dogs. Life has risks, but most of these can be managed.
Donning my asbestos suit, I'm going to emphatically disagree, especially given prior experiences in testifying about system integration and automation.elvisimprsntr said:It's not just about safety.

Shouldn't be a delay unless your contact has a really large gap. I'd change the rule to be 2 based on the open/closed using miscellaneous VM on the system.TLGriff said:I guess I didn't write my post very clearly. The first set of code is from Elk, which doesn't work. The second set shows the modifications I made to it and works fine. It is reading the garage door zone (Zn 15), but only after it is fully opened or closed. That was the problem with the Elk code. It read (Zn 15) before the door was fully closed. I have since shortened the pulse from 5 seconds to 2 seconds because as you mentioned, 5 seconds was way longer than necessary.
Thanks,

Really doesn't cover much or require much. Most modern GDO's have the secondary sensor (PE beams) so the only item that would be discretionary would be (thinking out loud) adding a basic chime/strobe in the garage timed before the auto operation begins. That's a belt/suspenders install, but it would be the HO's responsibility to prove you didn't follow UL.RAL said:There is a UL standard for door opener safety - UL 325. It was updated a few years ago to include safety requirements for doors that can close automatically. If your system meets the UL 325 standards, as well as any additional local building code requirements, you should be reasonably safe from any negligence and liability claims.

The commercial available interfaces and GDO's, yes. That said, anything homebrew would technically not be listed, though the integrator could also show that due dilligence and design criteria was met, however there's no way to prove that the warning devices were functional at the time of an incident, unfortunately.RAL said:Under the 2010 changes, audible and visual warnings are required for 5 seconds before the door starts to close. Not discretionary.
You could try and upgrade an older system to meet the current standards. But should you ever have any legal problems, you'd have an easier time if the system was manufactured under the current standards and listed as meeting them. Just that much less for the lawyers to argue about.
Though I agree this went pretty far off topic, it's not irrelevant info, and the flaming was minimal. We do not over-moderate here if things can work themselves out.TLGriff said:I'm surprised the mods have let this post get so far off topic. If Elvis wants to talk about garage door safety, perhaps he should start a thread of his own, instead of hijacking mine.
