ELK Transformer Help

I recently got a DSC PC1616 from a house that needs a 16.5vac/40va input. I got an ELK-TRG1640 transformer that came with it but its output is 16.5vac/45va. Can I still use this transformer and not hurt the system?


The Alarm system should be fine, as long as the transformer is 16.5vac.
