Just got my alarm (DSC Power632) working a couple days ago. Last night it went off for no apparant reason.
The alarm company tells me they received an "Expansion Module Tamper" alarm. What would cause this? Is this an alarm for the actual panel or could be a sensor?
The panel does have the cover open, but it's been that way since the beginning... any help would be greatly appreciated.

Do you have any expansion boards? (wireless reciever, etc)

I have 1 hardwired zone and a 433 wireless receiver with 11 zones.

I cannot find a diagram indicating if there is a hardwire tamper input for this receiver board, but there is a RF jam detect feature that is off by default, but if the panel was installed to UL standards, the feature would have been turned on.
I _think_ that there's a hardwire tamper input on this board, as well. I just can't lay my hands on the diagram.
RF Jam Detect Zone
For RF jamming detection to work, you must select an unused zone to be used as the RF Jam Detect zone. When the receiver detects an attempt to jam the RF signal, the RF Jam Detect zone will be violated and the system will generate a tamper signal. When the jamming signal is gone, the RF Jam Detect zone closes and the system sends a tamper restore signal.
