STI STI-14220FR Low Profile Horn Stopper
Overview
The STI-14220FR is a low-profile, surface-mount protective stopper unit designed to shield manual fire alarm stations, intercoms, emergency buttons, and access control keypads from vandalism, accidental impact, and environmental contamination. The fire label designation meets fire safety code requirements for public-facing emergency stations. The compact dome profile complies with ADA accessibility standards while maintaining a minimal visual footprint in corridors and entry areas. Operates at 24VDC, standard for most intercom and access control systems.
Compatibility
Universal design integrates with standard fire alarm stations, intercom keypads, emergency call buttons, and access control devices. Mounting adapts to surface-mount or recessed installation with internal mounting plate options. Confirm voltage and trigger compatibility with your system controller before ordering. Compatible across commercial, institutional, and light industrial access control deployments requiring fire-code-compliant protection.
Installation Notes
Surface-mount installation requires only straightforward fastening to wall or enclosure surface—no cavity preparation needed. Sealed mounting plate option available for wet or outdoor environments. Low-profile construction fits standard doorway and corridor clearances without protruding hazards. UV-stabilized polycarbonate cover resists yellowing and maintains clarity in direct sunlight. Optional 12–24VDC relay output supports integration with external alarm or signaling circuits. Gaskets included for environmental sealing.
