Car Alarms: false alarms, gmc sierra, convenience center

Question
I have a 99 gmc sierra I installed a commando 501s alarm in it. everything works fine, other than after it has been armed for 15 minutes it goes off for no apparent reason. i have the door triggers diode isolated. do you have any suggestions?

Answer
Well, the ways it can be triggered is
1, the dome light/door trigger is doing
a diagnostic, and the current is triggering it,
or the shock sensor is set too high.

My question for you is why are you diode isolated
any way? You should just use the green (-)
door trigger wire on the white (-)
door trigger wire at the Convenience Center.
It's Located Under The Driver's Dash Near
the Fire Wall (Listen for dome light relay).

Atattch without the use of diode.
and then it should correct this issue.
Try that and let me or, commando know
if it worked out that way.

It should.
