building which has such a door
system. It actually turns on an exhaust
fan for a few seconds when the
door moves. I really don't know what a
few seconds would do for
removing CO. But, if the door is left
open, after about a minute, it
closes. It does have an infrared
detector about 2 feet from the floor
which will stop the door from closing
and actually reverse it. BTW,
the funny thing about the whole design
is that if you don't want it to
close, you simply stop it before it
reaches top. It will then stay open
forever. We use it that way all the
time while loading and unloading.
Pretty stupid design if you ask me.
I'd buy one.
Every morning on the way out, I
1. Watch the door close all the way.
2. Say to myself three times out loud "I closed the garage door".
3. Turn around and look as I drive off.
4. Still wonder if I forgot to close it.
This is all on top of the normal checklist (wallet - phone - keys -
sunglasses - parking pass - badge - train ticket - zipper up - front
door locked - back door locked - basement door locked - windows closed
- space heater unplugged - furnace off/set - lights off). No wonder
I'm late for work all the time.
There's nothing in the house worth stealing but the garage is full of
tools and motorcycles. Too much temptation. It would be great if,
after 30 minutes of no motion in the garage, the door would close on
My opener has been known to almost completely close, then reverse itself. One
day I worked an entire 12 hour shift only to find the door wide open when I got
home. My garage is attached to the house and is my normal method of entrance so
essentially the front door to the house was wide open all day long. Luckily,
nobody decided to take advantage of it or I'd be in a world of hurt.
Now I back out, hit the remote, and wait until the door has closed completely...
and about 15 seconds more just to be sure. I don't move until I know it's
closed all the way... ever.
I don't know why a manufacturer would have to worry particularly about injuring
somebody with an unattended closing, particularly if the IR beams remain active.
It seems like the worst that could happen would be that the door wouldn't close
if something was in its way. It already does that.
I have read about devices that alert you within the house if the door stays open
more than X number of minutes. Maybe that'd be an option.

YEah, and if the door doesn't close when the label says it will,
that's ANOTHER liability problem. All of which the manufacturers
would be prepared to deal with or just tolerate, if they thought
enough people would pay enough more to make it worthwhile.
Which they don't, or there's be a system.
(If you want your door to close in order to keep
people for stealing your stuff, why are are you
willing to leave before it does so? and how is the
door going to know the difference between when you WANT
the thing up, and when you just forgot to shut it?)
That's indicative of an adjustment problem or an obstruction -- either
the stroke is a little long or there's a building binding that on
occasion is just enough to trip the force-limiting reversing switch.
An adjustment/cleaning/lubrication should eliminate the
problem...ignoring it will probably just increase the frequency of
As someone said if the door is in proper adjustment this feature would
be as safe (no less a liability) as any already built into garage
I don't even fiddle with my garage door for days before I leave the
state to go to my summer place.. I can't imaging leaving the house for
the summer through the garage door. I dissconnect the power and lock it
into place.. I'd wonder all summer if I closed it or if it
As it is, I make a false departure on my trip (1200 miles) . I lock up
and shut off everything real good , then I head out on the road (about
half a mile) with my car packed. But I go back and get out and check
everything one more time as a fail safe..
When I'm living at either place, I do what the other poster does , I
watch it annaly till it completly closes and often look back. Sometimes
the IR trips can work too good on those things..
The cat squishing option can only be a good thing..
The timers are readily available for electric openers and are typically used
on apartment house door openers. They consist of a timer box with two
lights, one green which when lit indicates it's safe to drive through the
door opening and one red light when lit indicates not to drive through
because the door is about to close. The timer can be set to start the
close cycle after a predetermined amout of time ususually about two - five

If you go through steps 1 - 3 and *still* wonder if you forgot to
close it, how would a time-controlled closing device relieve your
Wouldn't you just spend your day wondering if the device worked? If
you don't trust your own eyes, why do you think you would trust an
electro-mechanical device that operates outside of your field of
I can't imagine anyone making such a thing. Just think of what would
happen the first time a small child got killed, and even with all the
current safety devices, it would happen.
I suggest that you work on another idea. You could have a light that
would show inside whenever the door was up, or an audio alarm that would go
off after a pre-determined time. It could be in the garage or in the house.
Legal issues aside (should it malfunction), I made mine out of X10 parts.
USe a universal module to act as a switch and then get a controller to issue
commands when you want the door closed. IF desired a powerflash module can
be used to signal the controller the door is open and than have the
controller go into a X minute timer and than send a close door command
Go to www.smarthome.com for x10 info. THere are other sites with cheaper
The expensive one: http://www.smarthome.com/73101.html
There are also X10 sites that will tell you exactly how to do it also.
Now the disclaimer: IT aint cheap, and its not always reliable (there are
ways around that like sending each command twice)
I've been using this for a year now with no problems.... >>>>
It simply replaces the main controlling unit inside the garage and has a
receiver which mounts on the door to determine if it's open or close. It
does not take away from any safety features of the opener. It still allows
safety functions such as objects in the door area when closing.
The unit can be set to close in 2, 5, 10 and 20 minutes. With a simple touch
of the main unit, you can deactivate it if you want to keep the door open
while working inside the garage. AND...even if you forget to close the
garage after that, it will still close in about 2 hours. You can also
permanently deactivate with a touch of the button. But I've never used that
With the wife forgetting to close the garage door when she leaves or comes
home, I had to find something to auto close and this has been a blessing
since I have many of my tools and motorcycles inside.
For $40, it was the best investment I made for my piece of mind.
