clifford supernova 2, possible need of reset

1991 Toyota MR2 Turbo. This car has been in my garage since 2009 while getting work done to it on and off. The alarm worked before I parked it and while working on the car. Battery for the car has been disconnected for long periods of time between engine work. I had disconnected the alarm horn to reroute the wiring and when I connected it again and tried everything out I noticed this: I can program remotes and I can arm and disarm the alarm like before. The problem is that when the alarm is not triggered the alarm horn is going off. When I trigger the alarm the horn stops. So the horn is working backwards. Like I said I can program anything on the alarm but the horn is working backwards. Do I need to do a reset on the alarm and how do I do that? I have the valet code and that works fine too. Thanks.

Also I noticed that when I disconnect the brain and connect it back in I can feel the relay inside the brain click.

Never heard of that one before! Standard procedure was to disconnect power and ground for 2o minutes. But really is it worth it? That alarm must be at least 20 years old.

The car has gone weeks without any battery so that would of done it if that was the case.

Check the ground for both the alarm brain and the siren is good.sparky

Check what the last post says then bin it.

Does anyone know how to reset the brain in case I have to go that route?

At least one poster including myself has already told you. The fact that the battery was disconnected and it still went wrong means you've had it. It's a gonna.

Oh howei: I think what I want it to know was how to reset it. The fact that the car can be without power for days and I can still arm and disarm with the remote tells me that the brain needs to be reset through other means. It's ok if you don't know. It an old unit but really the only thing that it does not have is two way comm so if I can use it I would like to. Does anyone know the procedure to completely reset the brain. Thanks

The only way was to disconnect from power and ground for 20 minutes.
