An FACP must be able to operate its normal functions between which temperatures?

The main idea is that a fire alarm control panel must function reliably in typical indoor environments, where temperatures stay within a moderate range. Electronics and batteries don’t like extreme heat or freezing. If temperatures drop too low, components can fail to operate or batteries lose capacity; if temperatures run too high, electronics can overheat and wear out faster. So devices are specified to run within a safe, moderate window. That window is usually 32°F to 120°F (0°C to about 49°C). This aligns with common building HVAC conditions and NFPA 72 guidance, ensuring the panel can perform its normal functions in most occupied spaces and mechanical rooms without temperature-related issues. Ranges that dip below freezing or exceed the upper limit invite the kinds of problems described, so they’re less suitable for regular operation.
