PA2000 Alarm going mad on 993
Discussion
Hi all,
I went out to my 993 a few days ago to discover the battery was totally dead. Not a huge surprise as it hadn't been used for 3 weeks or so (although it normally copes ok). So, I unlocked the car manually with the key, removed the battery, recharged it and replaced it this morning.
However, as soon as I reconnect the battery, all hell breaks loose - horn, siren, flashing indicators, flashing interior light the lot. No amount of frantic plipping on the PA2000 fob will stop it. The only way to silence it seems to be to disconnect the battery again.
Any ideas how to reset the alarm? It seems to be cycling through various phases of using the horn only, siren only, siren and horn together.
Many thanks in advance for any suggestions to avoid getting lynched by angry neighbours.

I've had the same kind of problem on my 993. I turn the alarm off using the small key you should have. This goes into the alarm gubbings that's in the engine bay. I then connect the battery.
The alarm still goes off, but you don't get any noise, just lights flashing. You can then use the fob to turn the alarm off. Just remember to turn the alarm back on using the key again.
Hi Rob,
I understand the PA2000 has it's key inside the car rather than on the siren in the engine bay.
The location largely depends on the installer but one was recently found under the seat. All well and good if you have the key!
That said all it does is silence the siren so if you can't switch it off with the fob now you still won't be able to with a quiet siren either.
Have you tried sticking the immob key in the dash?
If nothing works it's not unheard of for these to go screwy after a flat battery. Hamilton and Palmer can diagnose faults and can also supply any parts required to fix these systems.

Thanks for the various suggestions. I've just tried a combination of all of them. There's no sign of an additional keyslot or key to go in it anyway. The alarm is now going off on siren only (no horn now) and stops after 30s or so. However, any attempt to disturb the car such as getting in it and starting it sets the alarm off for another 30s. Weirdly, the ignition and immobiliser work fine - it even starts and drives, but it's like the keyfobs no longer have any effect. Neither will lock or unlock the car. Unlock it with the key and the alarm goes off.
Every car I've had around this vintage the alarm's always been much more grief than the car

Hamilton and Palmer did all the P1000s and may have done the 2000s as well. Give them a call. V helpful people

I've got a PA2000 on my 964, which sometimes plays up when the battery goes flat. Do you have the H&P manual that came with it? If you go to FAQ on http://www.964uk.com, you can download a copy from there
Thanks for the info, I'll try them on Tuesday then 
. Yep, I've got the alarm manual which looks identical to the one on the 964 site. As it seems that the alarm has 'forgotten' the keyfobs I might try the process to teach it about a new fob and see if that works, but as I think that almost certainly requires a working fob I doubt it'll work.

Sadly, that didn't solve the problem for me, so I've had to remove the alarm board to send to H&P for refurbishment. The board itself is reasonably straightforward to remove. It's in a black metal box usually under the driver's seat, so you have to remove the seat, unbolt the box from the car floor and then open the box and slide out the circuitboard inside. One potentially difficult part is that the alarm box is held to the car floor and the box is held together with special security screws which need a tamperproof screwdriver to remove (available from RS Components).
Luckily for me, my 993 has a separate immobiliser so it can be driven while the board is away for refurbishment, although apparently some PA2000's have integrated immobilisers where this wouldn't be the case.
