Does the word, "signal", refer to sounding the horn?

In those same instructions it says, for scorer's equipment: "Scorebook, pencils, possession arrow & signaling device with sound
different from that of the timer."

How often is it where the scorer has a seperate signaling device?

Technically, according to the rules/regulations, it is the scorer that signals subs, not the timer. Yet how can that be done if the scorer does not have a separate signaling device?
