Door trigger problem for alarm, SCrew
When the door is opened the wires for the door or the dome light registure GROUND. When the doors are shut the wires show 12V. The alarm looks for Ground to show the door is open and triggers the alarm when armed. The GEM system goes into sleep mode at about 45 minutes. When that happens the wires go from showing 12V to being Grounded. I have tried a diode but then when the door is opened it doesnt show ground and the alarm is not trigged.
Any ideas.
