Fire alarm system installation involves designing, physically installing components (control panel, detectors, alarms, wiring), programming the system based on building layout and codes (like NFPA 72), and rigorous final testing to ensure reliable detection, alert occupants (audible/visual), and trigger emergency actions (like sprinkler activation or elevator recall), all managed by a central control panel to meet safety standards and code compliance. 

Fire alarm maintenance is a systematic process of inspecting, testing, cleaning, and repairing all components—like detectors, control panels, batteries, and notification devices (strobes/bells)—to ensure they function correctly, preventing false alarms and guaranteeing reliable fire detection and warning for life safety, involving regular checks (monthly/quarterly) and professional annual servicing to meet safety codes.
