I guess the unanswered question here is: is this a design/build opportunity, or has a security system been designed (drawn & sealed by an engineer)? If the design is done and you are just the procurer and installer, you are not responsible for more than proper installation. These things are a little like FA work, the trickiest part (once the layout and design work is done) is the programming, startup & test.
If this is a design / build project for the security system, I'd either locate an engineer or design specialist or decline the opportunity. More liability than you probably want to have handed to you. Tell the client you'd need a consultant engineer and the cost will have to be added to the project.
Out west here, alarm & low voltage installers make less than wiremen, and they operate under a different license (C7, I think). A regular electrical contractors license (C10) covers alarm work as well - in other words, a C10 electrical contractor does not need a C7 license to do alarm work, and they can hire wiremen or sound/alarm techs to do the installation work.
There are 10 types of people. Those who know binary, and those who don't.
