My Federal Signal SiraTone

A little demo of my 1985 SiraTone controller. It’s running off it’s internal 10 amp power supply. This is serial number E1725, which from what I can tell is the 725th controller manufactured. This unit shipped with an EOWS*612 and came with a low frequency, DTMF SiraTrol and had home remote positioning for live PA over radio. It was a top of the line SiraTone at the time. Pulsed signals are really hard on the supply, so that’s why I pulled the fuses on two amps before running them.
