Alpine Alarm sensor/activation question

[bosljeff]

I have an alpine alarm that when arms locks the doors and does other fancy stuff....anyway. If the alarm is armed and I unlock/open a door without disarming it, it should go off. If I bump it lightly it should chirp quietly, and any subsequent bumps should make the alarm go off.

Now, however, if I do any of the above, the alarm doesn't go off at all. In fact, the alarm light remains blinking, which it should cuz I didn't disarm it....

Ideas? I don't know how the 'sensors' work, but that is what is sounds like to me, but I don't know.

Thank you for your time.

Do your dome lights turn on when you open your door? If your door-pins are shot, then they won't open and the alarm won't know the door is open.

As for the shock sensor, there should be a dial or something of the like on it to adjust sensitivity.... but personally, I don't even use one. Door/hatch pins and a glass breakage sensor are good for me, and I never get falses

I thought of the door pins, but it wasn't that. It would be a freaky coincidence that all 3 doors went faulty at the same time. Also, I traced the system from alarm horn thing from under the hood, to the wiring behind fuse box, and I can't find any selenoid/servo/master box thing. How is it wired to the doors? Shouldn't there be something to sense the vibrations? This is a pretty decent alarm that shuts off ignition and so on, so if it isn't "sensing" anything, it is pretty useless.

Thanks.

OK, I checked this morning. I left the alarm armed and simply unlocked the doors, nothing. I fiddled with the plungers and still nothing. So it seems that the alarm doesn't know the doors are open or that the car is being bumped.

Are there sensors or something that could be dirty, or what?

Thanks.

Is your alarm horn just a horn?? How many wires from from it?? I'm guessing they just did a good job installing it and the wires go to behind the fuse box so you can't just trace them to the brain. You can try unhooking the siren (so you don't go deaf), and set the alarm off, most alarms, you can hear the relay for the parking lights ticking when they're flashing.

Check out this link to see where everything is *probably* hooked up, you might be able to figure out where the brain is from there. When I put my alarm in, I just went right at the pin switch, did you take them out and see if anything was attached to them?

No, not the car horn, but a P.A./speaker/horn looking thing that is part of the alpine system.

So, if I find the 'brain' what would be the next step?

Thanks again for the help.

yea, I meant the alarm horn, sorry, it should only be two wires, if it's more, you probably have an "all in one" car alarm... but I'm not sure if alpine made one of those.

Once you find the brain, find out what model alarm you have, and look around for installation instructions on the net so you know which wires do what. (or just trace wires from the brain, you'll be able to figure out which one is which from the link above).

If the wire that is supposed to trigger the door is hooked up, I'd unplug that plug from the brain, and get a multimeter, see if that wire is grounding out at the plug when the door is opened, if not, trace it all back and find out why. If it is grounding when the door is opened, and the alarm isn't sounding, that's a programming option (or a broken alarm), and you'll probably have to find an Alpine installer to change it.
