What was that light/siren system (plus others) that can be controlled by a laptop?

Specifically I'm thinking of and earlier siren system that you could run off the laptop. I believe it was Federal Signal related but not certain. I do not use or deal with sirens so I do not keep up with the ever changing advancements.

More interested in one that would do light controls so curious as to what other older systems can operate lights via laptop? I am not a computer person but think I have read about custom systems that connect via usb to control relay banks. Just exploring the idea for my home display to be PC controlled (at least partly).

With the Fire service there is no one meaning that is absalutely right or wrong. It just depends on where you are and what they use it in reference to.
