Home Security System Repair Questions? Ask a Technician.
Hello, my name is***** to Justanswer! Give me just a few minutes to look up some specifics, I'm working on this now.
Do you still need help with this?
Sorry for the delay, your money is just a deposit at this point.
Does it otherwise function properly? Just the alarm won't sound from the door triggers, but it does sound when you test it?
There is a switch inside the unit that seems to have fried. It's attached to the trigger circuitry, and it's not switching to trip the alarm. Since you can hear it on a test, we know the alarm works, and that the triggers are working because you can see it in the system when a door opens. We would need advanced schematics to fix the thing. You're going to have to call ADT and schedule a repair. (###) ###-####
How advanced are the schematics you have? It's a tiny switch that is triggered by the sensors, and sends the signal to your alarm circuit to sound the alarm.
It doesn't look like a switch, it will be either a little white box, or a capacitor looking thing. Should read 0vdc on the output of the switch.
It should read between 12 and 18vdc when it's open. It opens and closes when a door is opened, when the system is armed. You will read a short when a door is open, and an open when the door is shut.
If there is no change and it always reads open, that's the switch.
0vdc stands for zero volts DC. It's going to be soldered to a green circuit board, and it will have to be tested with a multimeter. Have you worked on electronics in the past?
Ok, you're going to need someone who knows their way around a multimeter to do this. The switch doesn't look like anything you're used to.
That's great! Poking around may have freed the switch. Does it go off when you open a door?
Ok, well it needs to be done by someone who needs to use a multimeter. An electronic switch should be replaced by a technician who knows how to run these tests. You should show them our conversation about the switch, and they will be able to do the necessary testing and replacement of the switch.
I would try the local electronics repair shops. Which city are you nearest to?
I would start here, they have the guys who've been in the business and would know your system..

Try the installers, the ones who really know their stuff will know repairs on yours. If you still have no luck, I would take the entire control panel into a full service electronics repair shop and tell them about the switch that doesn't appear to work.
