FSK is associated with which standard in alarm signaling?

• A. SIA
• B. UL
• C. ISO
• D. NFPA

Answer: (A)

FSK stands for Frequency Shift Keying, a way to modulate data during alarm signaling. In the alarm industry, the formats and transmission methods used between control panels and central stations are standardized by the Security Industry Association (SIA). That’s why FSK is associated with SIA. Other organizations serve different roles: UL focuses on safety testing and certification of equipment, ISO sets broad international standards, and NFPA publishes fire and life-safety codes—none of these specifically define the FSK signaling format used in alarm signaling like SIA does.
