I had a manufacturing location in NY area a bit smaller that on a 10 acre site. It had OH doors in a shipping area, separate storage and wharehouse areas all isolated from each other with the main controller keypad in my office and a separate slaved keypad and badge reader at the assigned employee entrance from Access Control system that was linked to the Security system.
My security hardware was Honeywell (Ademco), the access system was WinPack. I had the security system hard wired and had it self test itself and comms every 4 to 6 hrs. The building was divided into separate production and office areas so each could be armed/disarmed by authorized badge holder or schedule depending on the areas purpose. Using the Access System to disarm on an authorized badge user took the confusion of the employees out of the process for the most part. It does require using a command file sent from the server to arm or disarm on an authorized entry but keep in mind a remotely located server may cause comm failures if IT has issues. It should not be a problem inside the actual building.. We used HID and iClass readers and cards. We also used a keypad acting as a reader input to arm manually by the exit with a common code as well as an autoarm schedule JIC.
I have 26 location currently using Bosch GV2's that we are replacing with DMP systems, wireless in my smaller location.
DMP: I havent had any problems to date after about 1 year. There is one issue on using dual cellular that is built in because of a patent issue where the one of the cell modem cannot be used as the primary modem but I used a cell bu as well so for me its not a problem, it was a problem when we used TelGuard systems for BU because the telGuard became the primary and that limited point ID too much.
Bosch: Has always been a rock solid system, especially in Lightning Strike city. I have had only one in 30 panels fry from an overload. Their database on the other hand is a nightmare because they have not fixed the date issue that requires using 1999 to search and that cannot time stamp the event with a proper year. Steer clear unless year dating is not a problem but for court records you cant prove the date of occurrence.
Ademco/Honeywell: N1000 and NetAXS I have used a few different acess system and they all have their own quirks in the software. The ademco hardware is solid and resistant to problems mand over a networked area latency isnt a problem for remote locations. If you plan on having a system with a lot of readers, each panel contains 2 or 4 doors you might want to look at the blade system where you add circutit boards to a main opanel instead of adding individual panels and try to locate the main panel room centraly in the building to cut costs on excessive wiring. I wont recommend wireless on any security except maybe door contacts but thats just a personal thing.
Good luck.
