Good evening all, I am renovating the fire alarm system in a 12 unit apartment building out here in atlanta, ga. i am taking out the old 5 zone panel and adding a firelite ms9050. The whole building currently has 12 horn onlys and 3 horn strobes on each floor breezeway. I need to add additional 8 horn/strobes and 8 strobe onlys. Do you guys think that this panel can handle this or do i need a power supply? Thanks in advance. Also this panel has 2 nac circuits at 2.5 amps each.
