Fire alarm systems require how many reliable power supplies?

Explanation:
Redundancy in power supplies is essential for life-safety fire alarm systems. They must stay operable even if the main power fails or a power path has an issue. That’s why two independent, reliable sources are required: a primary source from the building’s normal electrical supply and a secondary standby source (typically a battery-backed UPS and/or generator). The standby source automatically takes over to keep the system running—ensuring alarms, indicators, and monitoring continue during outages. This dual-source setup is the standard approach to maintain operation under with power interruptions.
