Well you came asking for help and your disregarding what you are told by people that work with this stuff every day. I have told you how to rule this out and some things to check, there are further things that need ruling out but it's not normal. To expand on MrH above, as a rule of thumb I would expect each power supply to have <~500mA quiescent per 7Ah battery to conform to BS EN; this is aside to your issue.2 points

That's nice... did you read the installation book where it states the size of the psu & the current drawn by each texecom device ? You have the main board, 5 expanders, 5 speakers & a keypad I also assume you have an external bell(s) & powered detection All powered by the panel....1 point
