Alarm disarms, but when triggered, it doesn't!?

Hi, I have a Pursuit Pro9231 that hooks into my existing stock keyless entry system on a '02 Lancer.  I have disarm input#1 to the cars priority unlock motor wire(+) and disarm input#2 to a constant ground.  The car arms and disarms fine with the remote, but when the alarm is going off (triggered), I can't get it to disarm.  After the 30 second cycle is fine, the alarm arms and disarms with the remote just fine.  It just does not respond when the alarm is in its triggered state. 

Someone told me to disconnect the main harness for 30 seconds so everything will reset and recognize the polarity of the wire setup when it was reconnected.  It didn't seem to help me any.  Any suggestions?

Thanks.

Hi metidogeno, if I recall correctly, the 9231 has 4 programming switches. One of them is for 1 or 2 wire disarm and another is for positive or negative disarm. Make sure you have them in the correct positions (sorry, I don't remember which). If you are unsure of which direction they should be, try both, it won't harm the alarm. If this doesn't solve your problem,  you may need to connect the disarm input #2 to the all unlock wire or even disconnect it with the programming switch set to 1 wire disarm. Let us know how you make out. If necessary, I'll hunt for a manual and any notes this evening to see if I can find any more info.

Thanks 12volt.  The car is a negative door lock system but I had to switch it to (+) for the motor wires since these are the only wires energized with the stock remote.  I have the alarm on the 1-wire disarm.  I'll try switching it to 2-wire disarm and see what happens.  But shouldn't it work under 1-wire disarm w/ disarm input#2 grounded? 

Thanks again 12volt.

Hi metidogeno, it may be necessary to disconnect it when configured for 1 wire disarm.

The 12volt,

That's what I originally did, but it still wouldn't disarm in triggered state.  I think the alarm may be defective since it still disarms when the alarm isn't going off.

Thanks.

Hi metidogeno,, I've experienced this in the past, but it wasn't because of a defective alarm. It's been a while since I've installed a 9231, but when I get home this evening, I'll look for any notes I may have on it. I'm willing to bet it's a simply problem with a simple solution. In the meantime, if you can, try the things I've suggested.

Thanks 12volt.  That's comforting to know that you've ran into similar problems.  I'll try the things you told me when I get home.  Yeah, please let me know if you figure out this weird dilemma.

Also, the reason I didn't originally hook up the disarm2 wire to the "all unlock on the car," is that if someone (such as a passenger waiting in the car) locks the car from the inside and the car arms, I still would like to have the freedom to unlock it from the inside if it was accidently armed.  If I hook up the disarm2 wire to the all unlock, the car will not disarm and the passenger is likely to set it off by either triggering the shock sensor or opening the door.  Is my understanding of this correct?

Thanks.

Well yes, that can happen, but typically when someone is in the vehicle, the key is likely to be in the on position, but you could install a switch on the arm lead to to prevent it from arming if the key is not in the on position and a passenger is in the vehicle and happens to use the door lock switch (then again, it's just as easy to tell them not to lock the doors unless they exit the vehicle or feel they have to). The door locks will work either way. But like I said, I'm sure the disarming problem has to do with the way you've connected the disarm wires and/or the setting of the 1-2 wire disarm programming switch.

You're right, most likely I would leave the keys in the car if someone is waiting.  That was fun...I made a small concern sound like a huge problem.  I just can't believe that the car is not disarming in the triggered state.  To me, I would think that the disarming of the alarm should either work or not work; not only when it is not triggered.  I feel that is the logical way of understanding this.  Previous to the posts, I had it hooked up to 1-wire disarm with the input2 wire disconnected, and this is when the problem started. 

Sorry for all the whining, I just hope you find a simple solution for me.  Thanks again 12volt.

No problem, just try what I already mentioned and if the problem still exist, we'll go from there.

12volt,

Please email me or post a message if you find any notes on this alarm.

Thanks,

I had seen this type of problem along time ago.  On this paticular install, the customer wanted a pager unit installed so he could know when his alarm was going off.   So arming/disarming worked fine,  but when the alarm was going off,  the pager unit was transmitting and because of the location of it,  it was creating RF interference with the Receiver part of the alarm that receives the transmitted data from the remote.    Moving the pager unit far away from the alarm solved the problem.

So,  just in case you have something like that, that could be the problem.  If not,  check for something else that may be interfering only when the alarm is triggered.   Or it could be a problem with the alarm itself.   I used to repair some alarms several years ago and I think I came across one with the problem you described.   Typicall I would have replaced the Microprocessor.   However this was a rare problem.

Good luck.

Hi Thinkster, while I've seen alarms encounter the same problem you described with a pager, this particular unit usually has this problem when the disarm leads are not connected properly and/or the programming switches are not set correctly. 

BTW metidogeno, I haven't had a chance to hunt through my notes, but you should have been able to solve the problem with the remedies I described. If you haven't, let me know.

The 12volt,

I tried the following and the problem still occurs:

--1wire disarm switched on, disconnected input#2 wire

--2wire disarm switched on, connected input#2 wire to "all unlock wire on car when remote unlc**k button is pushed twice."

--I even switched between 1wire disarm to 2wire disarm with the described setups and the darn thing still won't disarm when triggered! 

P.S.  I'm starting to have nightmares in my sleep about this.
