The front desk sounds different from the dispensary.
Five tones ship in the Spa pack. Each channel your team signals on carries one of them, chosen once for the whole spa, so a signal from the desk never arrives sounding like a signal from the back of house.
Tap any tone to hear it. These are the recordings themselves, the same five files the app plays, not impressions of them.
One tone per channel
A channel is a line your team signals on: the front desk, the dispensary, housekeeping. Each one carries a tone, set once and shared by the whole spa. Every screen hears the same tone for the same channel, which is what makes it mean something.
One pack per device
A pack is which recordings those tones play from. Classic ships with the app; Spa is the pack on this page. Each device picks its own, and picking changes nothing for anyone else. The channels keep their tones and their numbers exactly as they were.
The alarm never changes
There is one emergency sound. It is the same recording in every pack, it is not one of the five, and nobody can choose it, rename it, or soften it. A calm pack must never quiet the one signal that means someone is in trouble.
The number is the part your team says out loud. “Put the dispensary on Sound 3” works whichever pack each screen is running, because the number belongs to the channel and the name belongs to the pack.
What the app does not do.
There are no quiet hours in AltoSignal, and no schedule. Inside AltoSignal a screen sets four things: which of the two packs it plays, how loud its alert is (an Alert volume slider, per screen, within whatever the device itself is set to), whether the alert repeats until someone answers it, and whether it makes a sound at all.
A room that should hear nothing gets a screen with its alert sound switched off, under Alert sounds. That is set per screen, so the front desk stays audible. The emergency alarm still sounds on a silenced screen, at full volume, and nothing in the app can turn that down or off.
Hear them on your own devices.
Both packs ship with every plan. A screen picks its pack under Alert sounds, or switches its sound off there entirely; a channel’s tone is set once, from the channel list. Both take a moment during setup.
