Fire alarm device wiring

Can anyone recommend some good books to learn about commercial fire alarm system. Regarding devices… Are there signaling, notification and annunciation devices? Do they all get a pair of wires except say speaker/strobes? Thanks

NFPA 72 would be a good start.

Depending on the model, they can either use one or two pairs of wires. The ones that use two pairs will power the horn and strobe separately.
