Not only the business owner but you too if you installed the system. This is the reason security companies pay more for insurance then we do. I know insurance companies recently raised the rates for electricians because they install smoke detectors.

About all an attorney is going to tell you is anybody can sue anybody for any reason so it's not a question of whether he can be sued but rather how to protect himself if he is.

I would think his general liability would cover this and it would be best to check with his agent about his concerns.
