The STI-13020FR is a flush-mount universal stopper device with integrated 105dB sounder, designed to protect manual fire alarm stations, emergency buttons, keypads, intercoms, and electrical switches from vandalism and environmental damage. Operating at 24VDC, it mounts flush against wall surfaces and fits both indoor and wet environments. The thick polycarbonate cap and waterproof enclosure option shield protected equipment from dust, moisture, and casual interference while allowing authorized personnel rapid access when needed.
The STI-13020FR accommodates most standard fire alarm station geometries and emergency device footprints. Its universal design integrates into building fire alarm systems and access control architectures that operate at 24VDC. Waterproof enclosure variant available for outdoor or high-moisture installations. The optional relay output (12–24VDC) enables integration with building management systems and third-party alarm logic. Check your specific alarm station dimensions against the STI mounting template before ordering — the stopper is dimensioned to fit most common manual stations, but custom layouts may require site verification.
Available in flush-mount configuration (recessed into wall) or surface-mount with waterproof sealing plate. The top and bottom of the waterproof enclosure are threaded for ¾-inch rigid conduit. ADA compliant low-profile design. Integrated hinge is solid—no moving parts to fail. Gaskets and seals included. Do not use the latch tab on fire alarm installations (latch blocks emergency access). No special tools required; standard mounting hardware suitable for drywall, masonry, or structural framing depending on enclosure type. UV-stabilized polycarbonate maintains transparency outdoors.
