Link alarm to garage door opener

[Craikeybaby]

I've got a Hormann Promatic garage door opener with a 2 button remote, but only one button is used to open/close the door. I want to fit an alarm to the garage (possibly not needed, but old garage was broken in to) but trying to work out how best to set it up, so that when the garage door is opened with the remote the alarm is disarmed.

I'm thinking either using the second button on the remote, althogh some confirmation would be needed that the alarm is disarmed, before opening the garage. Or somehow getting a signal out of the door mechanism to deactivate the alarm.

Does anybody have a similar set up? Or ideas on how this could be achieved?

Thanks. The installer did day that if I can get a signal to the alarm it should be possible to disarm it.

I don't want to leave it with a long entry delay on the alarm as it takes some manoeuvring to get into the garage, so the time delay would give plenty of time for someone to get in and out with bikes/tools etc.

I want to be able to deactivate the alarm from in the car.

Thanks.

I'll dig into that a bit further, a quick Google didn't bring up any wiring diagrams, but will see what I can find.

This is all very interesting - thank you!

I was planning a Texecom Veritas alarm anyway, as that is what I've got in the house. So instead of using the Hormann fob to activate the alarm I use the alarm fob to open/shut the door.

I've done a bit more digging on this and I think I have 2 options:

Add a relay to the opener, which bypasses the signal from the sensor when the door opens. (Cheaper, but less secure)
Or add another reviever to work with the second button on the remote and link that to the key switch on the alarm panel to switch on/off the alarm. (More complicated, but more secure).

I hadn't seen that. Hormann keep referring me to their local dealer, who are a bit rubbish at this.

The door alarm looks like it just protects the door, but I'm more concerned about the personnel door and the window, as the wain door is pretty secure.

I want to be able to get in though!

Thanks for the feedback. I'd pretty much decided to go for your first suggestion anyway. The installer is setting it up today.
