Team,
I'm putting together a proposal for 30 door system and requested my UTC local dealer to help with the design of the solution. I've used ATS2099 panel and ATS1170 before in another site and would say the solution was quite stable and would not mind using it again on this particular situation. However, going through UTC site, I'm not sure why my dealer loves quoting ATS1170 which is a single door controller instead of the 4-door controllers like ATS1250, as I'm looking to implement Reader IN/OUT on each door for the 30 doors. May I request anyone with literature or knowledge with reference resources to help me understand this design. Also would be interested in understanding when to use DGPs & RAS.
Thanks in advance good people.
