A complete guide to wireless fire alarm systems — how they work, what NFPA 72 Chapter 23 requires, where they are the right solution, and what designers need to know about supervision intervals, battery life, and RF interference.
A wireless fire alarm system replaces hardwired initiating device circuits (IDCs) and signaling line circuits (SLCs) with radio frequency (RF) communication between devices and the fire alarm control panel (FACP). Devices — smoke detectors, heat detectors, pull stations, notification appliances, and modules — transmit their status to the panel or to intermediate repeater/mesh nodes using proprietary radio protocols rather than copper wire.
