The Kidde 2447TH-W is a 24V DC temporal pattern fire alarm horn built for conventional commercial fire alarm systems. It delivers the ANSI/NFPA 72 temporal-3 audible signal that occupants and AHJs expect, running off the panel's NAC circuit with no additional power supply runs.
Built for the commercial installer
Part of Kidde's 2400 Series conventional notification appliance line, the 2447TH-W mounts on standard electrical backboxes and connects directly to the building's 24V DC NAC circuit. Two-wire hookup, no addressing, no programming. The white finish blends with standard commercial ceiling and wall surfaces without drawing attention.

System requirements
Requires a conventional fire alarm control panel with a 24V DC NAC (Notification Appliance Circuit). Verify the panel's NAC amperage capacity against the horn's current draw before adding devices to the circuit.
