What CSI Codes Do You Normal List Yourself Under?

An application is asking us for the CSI codes. There are dozens that we can fall under. What are the ones that you normally use?


Do you do video surveillance and access control?

Do you replace door hardware/locks?

Do you install structured cabling?

Do you install intrusion alarms?

Do you install Public Address/Intercoms?

You should know that the CSI Materformat Sections are being revised. Here is a link to the most current sections starting with the FAQ "What's My MasterFormat Number" . Most I would think work in Division 28 for security and fire alarms. But some integrators work in Division 27 if they install telephones, network communications, etc. There is also Div 8 if you deal with door hardware and a division that deals with building automation (Division 25).
