Is it possible to Wire A fire alarm system without a FACP?

I was wondering is it possible to wire up a Fire Alarm system without a Fire Alarm Control Panel?
My idea is voltage, Pull Alarm, Photoelectric Smoke Detectors, Firehorn/strobes

Can anyone help here?

This has been asked on this forum before. See this thread.

This video here is actually a great example of a fire alarm system that doesn’t have a Fire Alarm Panel and how it would be wired up to the building that isn’t connected to a controlling component. Basically, the system and it’s relative components are wired and fed directly from the buildings AC circuitry. I’m not sure if it would work the same way with a DC horn system or if it has to be connected differently.
