He's right, just look at the pictures
I would meter the voltages. Your labeling doesn't line up with standard colours for the power.
Are you sure it's not TT + - NC from top to bottom ? With red being +12V and black being 0V ?
If you can get that right, then it's green and white to the two tamper NC terminals (doesn't matter which way around). Red to +Vin. Black to GND. And blue and yellow to the two Relay NC terminals (again does not matter which way around).
As I say though, check that black and red have 12V dc.
What are you on about there are no "standard colours" for anything in the alarm business................. Your labeling doesn't line up with standard colours for the power.
It's pretty much common sense for red and black to be wired as power. To obfuscate power cabling is unwise and will only lead to blown fuses and damaged equipment.
If it's something that you practice, then you're in the minority.
