Hi. I have a VW Polo 9n 2003, is similar to Fabia 1, central locking, two electric windows and I installed a remote central locking with alarm. I wired up the lock - unlock wires to CCM, pin 6, the unlock wire with a 220 ohm resistor and works fine. The alarm module has two wires, door trigger negative and door trigger positive. I tied the negative door trigger wire to the Power supply control unit, plug XS4, pin 6 (front left door switch input). When I disarm the car and I do not open any door, the alarm module rearms the car after 30 seconds. If I disarm the car and open the front left door the alarm module notice this and do not rearms the car. I found the other doors switch input in the plug XS4 (pin3 rear right door, pin4 front right door, pin13 rear left door), I tried each pin separately with the negative door trigger wire and it did not work, the alarm module rearmed the car after 30 seconds. I measured the voltage on the pins, pin6 had 7.5 volts, pin3, 4, 13 had 4.5 volts. Where did I go wrong?

Is your Polo left hand drive or right hand drive?

Left hand drive. 

Does the audible warning work if you leave the lights on , take out the ignition key and then open the door to leave?

Yes, all door locks, microswitches was repaired, remaked the solders. 

My big question is, where to connect the 'door negative trigger' wire and how to connect all doors to this wire?

Reading this again makes me think "Is this not just normal behaviour?"

I'm fairly sure that on both our (remote central locking) cars, if you unlock with remote, then don't open any doors within 30 seconds, the car re-locks itself. Designed so that accidental pressing of the unlock button when you are within range of the car doesn't leave the car unlocked. 

Yes, this is normal. My problem is when I unlock the car with remote, and open the passenger door, or any rear door, the alarm does not recognize this. Because i don't know how to connect these doors to alarm unit. 

Ah, sorry, I didn't understand.

 

No problem.
