The Federal Signal Controller Model FC is a 120VAC radio receiver/decoder and timer with relay outputs. This versatile model is ideal for virtually all siren control applications and any other process which can be controlled via relay contacts.

The microprocessor–based controller comes with two–tone sequential, dual–tone multiple frequency (DTMF), or frequency shift keying (FSK) decoding capabilities, and up to four individually programmable relays.

Options include a synthesized radio receiver (low band, high band, or UHF), a built–in tone generator, which adds six standard tones, public address capability, and a software package that allows the unit to be connected to any IBM–compatible computer to modify supplied timing or to create unique tone patterns. Programming options include radio receiver frequency, two–tone sequential tones/DTMF/FSK decoding digits, custom audible signal tones, and independent control of output relays and timing patterns for electromechanical sirens.

Up to six control codes may be programmed and activated by any combination of two–tone sequential, DTMF or FSK tone bursts. Four of the timing sequences can be initiated using local push buttons or remotely through dry contact closures.

The Federal Controller is used to control Federal Signal siren Models 2, 2001 and STH10. Also, the unit can be used to add radio activation of indoor PA and SelecTone systems, to control warning lights, or to replace existing and outdated electro–mechanical timing mechanisms for existing systems.
