SynC · Topic
These are the standards in the SynC Standards library that cover Emergency Communication Systems. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
In-building, wide-area, and distributed-recipient emergency communications systems (ECS) — commonly called mass notification systems (MNS) — that warn occupants and the public of fire and non-fire emergencies and instruct them on the appropriate protective action, in accordance with NFPA 72 Chapter 24. Covers the risk-analysis basis of design that establishes the need for and scope of an MNS; the autonomous control unit (ACU) and local operating consoles (LOC); in-building MNS using voice/alarm communications and visible notification and signage; wide-area MNS using high-power speaker arrays for outdoor and campus-scale coverage; distributed-recipient MNS using text, email, telephone, and mobile-app delivery, and interfaces to the public-alerting infrastructure (IPAWS, Wireless Emergency Alerts, and the Emergency Alert System); message prioritization and integration with the fire alarm system; voice intelligibility requirements and acceptance testing using the Speech Transmission Index and the Common Intelligibility Scale; pathway survivability; primary and secondary power; and commissioning and intelligibility testing. Typical applications include higher-education and K-12 campuses, healthcare and hospital campuses, military and federal facilities subject to UFC 4-021-01, high-rise and large assembly occupancies, transportation terminals, and corporate and industrial sites.
