Tyco 472488-F Supervised Horn/Strobe SIM Module

The Tyco 472488‑F Supervised Horn/Strobe SIM Module is a fire alarm accessory module designed to control and supervise horn and strobe signaling appliances. It integrates with compatible alarm panels to manage audible horns and visible strobes, ensuring that both sound and flashing light signals are coordinated and supervised for integrity. The module ensures that wiring faults such as open or short circuits are detected, providing supervisory signals back to the control panel. It supports regulated voltage input (often in the 24 VDC range) and can handle both horn and strobe loads according to NFPA / UL standards. The device allows for mounting in standard back‑box hardware, facilitates field wiring for multiple circuits, and often supports selectable candela levels for the strobe. The housing is rugged to meet environmental conditions typical of indoor fire protection installations. This SIM Module is used where building codes require visible and audible alerts and a supervised circuit such that failure of components triggers a fault indication.
