Good Morning. My son's Alarm box is showing a Red Power and Tamper light. Does anyone have any suggestions as to whether this can be fixed without and engineer?

We have no idea what model panel you have but seems like you have a tamper fault which will need diagnosis.

Understanding electronics and owning a multimeter would be a starting point, there's live electrics inside the control box.

The red light is normal the tamper light could be anything, every circuit has a 24hr alarm circuit called tamper, if someone tampers with the alarm while its unset the alarm activates to warn the owner that someone is tampering with it. Putting the wrong code in the alarm several times could also cause tamper.  As SWB says its difficult to tell you what the cause or fix is without more info and knowing your technical ability we are alarm monkeys not magicians  

It depends on what panel maybe upload a photo of it?
