Outdoor Warning

FC Siren Controller

  • Remote radio control function available
  • Controls warning lights and audible devices
  • Two-tone sequential, DTMF and digital FSK decoding
  • Four individually programmable output relays
  • Push-button local control or dry-contact closure inputs for landline control
  • Six built-in siren tone signals

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 ECLIPSE8. 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used to add radio activation of indoor PA and SelecTone® systems, to control warning lights, or to replace existing and outdated electro-mechanical timing mechanisms for existing systems.

Special Considerations

  • Specify voltage (120VAC or 240VAC)
  • Specify radio frequency
  • Specify antenna (RP164) high band or UHF band (one-way)
  • Specify options
    • Programming Software(FSPWARE)
    • Tone coded squelch decoder (CTCSS/PL)
  • Call the factory for assistance in specifying an outdoor warning system
