Overhead Door Contact False Alarming, Need Information Before Pursuing An Account

Take a look at GRI - 4700-A Series Industrial Track Mount - I found that the worst place for the contact is on the concrete - These seem to eliminate any issues.

There's really no way to answer this question without actually looking at the door, preferably on a windy day. 

If you have a very large amount of vertical motion, which is possible with an older door or a door that has been dented, use a track mounted contact, as Chris suggests. Otherwise, use a good quality wide gap contact. 

Usually, I mount OH door contacts on the concrete floor. I use a wide gap contact and test the door by locking it then shaking the door. I test all magnetic contact installs, windows and doors, with a shake test. If I find a OH door the needs maintenance, I’ll tell the customer and have them initial a document acknowledging the door problem. I may wait until the door is fixed if it’s really bad. These types of doors are not that much of a problem to troubleshoot.

Some doors will not accommodate a track mounted contact, and the only way is to mount them is on the floor.  Another method could be using two contacts in parallel if it is an extreme case where the door is loose and sloppy.

Look at the door.

Floor mounting is an option until you see someone rip one of the upper door panels out and leave the bottom one in place.

My experience is that overheads tend to false in environments where there are careless forklift operators or really sloppy doors. Worst case, rewire that zone with a new wide gap industrial contact. I wouldnt let that deter you, if youre not going to cover overhead doors youre limiting your commercial market severely.

I ordered the GRI 4700 but it's not going to work, or at least not without serious modification.

The door is a POS, it's a landscaping company so not much care is given to the shop. The door has no bottom tracks and I think the door is sitting on the floor, with the upper guide rollers just sort of aiming it. I suspect the upper rollers slap worn out/broken. If I pull on the door, it can move at least 1.5 inches away from the wall. I do not mean side to side as if you were opening it. I mean if you walk up and just pull the door toward you.

Suggestions?

The panel is a DSC Neo and I am wondering if a curtain motion detector would be the best solution here

So this is a horizontal sliding door and it doesn't appear to have a track at the bottom to keep it from being moved inward from the wind. Yes the contact that is there probably won't work. From picture it looks like the actual contact is not secured to the wall thus making the break distance even shorter. This door appears to be homemade and not very secure. I would suggest, if the customer can be careful, would be a pull cord type of contact. One would be the following by Interlogix but there are others as well. You have to mount it so that if they don't unplug it first it will but out by itself. This has been a good solution for me when I have come across a situation like this.

If the door has 1.5" of play with no effort, a strong wind is going to move it 3" or more. 

Use a curtain PIR.

Crazy thought, how about a hasp lock on the inside near the contact?

Mounting that contact higher, closer to the top, but still side mounted should be fine. The top rail should prevent the top part of the door from moving more than the bottom part of the door. You can test this by wiggling the door. Or, have the property owner install a sturdy lock which will help to immobilize the door.

Thanks, Shannon, that is perfect. I was thinking of something like that but did not want to rig something up.
