A quick question guys, when doing a fire alarm weekly test do you have to do every call point.

No, it's never been a requirement - just a single different call point each week gradually rotating them so each one gets tested eventually. A long time ago you had to have tested every call point within 13 weeks meaning on big systems you did have to test more than one a week, but that was dropped a long time ago - after all the service organisation should test 100% of call points each year across it's 2 or more service visits anyway.
