This has not to do with alarm, but with the closing mechanism of the 147. Did you ever noticed that when you close the car, the indicators light up one time (a bit longer than normal). If a door is open, the side indicators light up one time.......and then light up two times to tell you a door is open! NIFTY feature hey! If you didn't know, just try it. I now always have a look if it beeps once or more wink
Oh yeah, if a door isn't closed, the car WON'T lock!</strong><hr /></blockquote><font size="1" face="Verdana, Helvetica, sans-serif">Mel,
The alarm we talk about is META MP750/7
, designed to interfere perfectly with 147's electrics. It (dis-) arms by the car's (un)lock mechanism and its fully compatible with it. You are right about the car's feature, all Meta Alarms have the same behaviour though (a friend has MP870 at his Punto and it behaves the same as mine)
Hugo, you dont have the Spyball sensor (unless u have a Spyball alarm at your 147). Its build-in at Spyball alarms but its also as an external independent unit available, so u can add it to any other alarm. Thats what i did, Meta MP750 has anything except a vibration sensor, so i added the Spyball sensor i had from my previous car (i had LaserLine Alarm to my Pug).
This sensor actually is a small ball inside a bigger globular chamber (about 15mm big). The inner ball is free to move inside the bigger one and its movement is monitored by infrared beams. The movement data are controlled by a cpu and if they are found "suspicious" (car was vibrated, moved etc.) an activation signal is given to the car's alarm to start shouting. It has a sensitivity potentiometer and its quite reliable. No false alarms if adjusted carefully. It costs about €30.
