Multitone TrueAlert

No, it has to be coded by the panel.

The horn on that TrueAlert sounds different then the horns on the other TrueAlerts I heard.

Yeah, the horn is a half-step lower in pitch than normal TrueAlerts.

Glad to finally see/hear one of these in action. Pretty much what I expected - the regular horn sounds close (not quite identical) to a regular TrueAlert, while the others are close to the Wheelock MT tones. Thanks for sharing!
