[bsp-forum] Person Machine Interface (PMI)

["Deborah MacPherson" <debmacp@xxxxxxxxx>]

Hi Michelle and Rex,

I'm reviewing a digital addressable fire-alarm system for a hotel. The paragraph below caught my attention and wanted to pass along to you see if this is realistic or achievable. It makes me now worried about the Building Control System requirements too. Typically I only review for conflicts with the contract and similar but I couldn't help notice this perhaps unachievable result.

Any expertise or comments would be sincerely appreciated.

Thanks - Deborah
