The STI STI-9665 is a protective wire cage designed to shield beacon and sounder units from vandalism, impact damage, and accidental contact. Fabricated from 9-gauge steel wire with polyester-resistant coating, it mounts directly to beacons and sounders in controlled indoor environments (offices, control rooms, server areas) where equipment abuse is a concern or uptime is critical. The STI-9665 prevents physical damage while maintaining full audio and visual functionality of the protected unit.
The STI-9665 works with STI beacon and sounder models in the STI-9614, STI-9664, STI-9615, and STI-9617 families. Verify your specific beacon or sounder model number against STI documentation to confirm compatible cage dimensions before ordering. The cage is sized to fit standard STI sounder housings used in access control and life-safety alarm systems.
Installation is straightforward: mounting screws and anchors are included. No special tools or fasteners are required beyond a standard screwdriver. The cage mounts externally to the beacon or sounder enclosure in minutes. The unit is rated for indoor, controlled environments only—do not install in outdoor, wet, or corrosive settings. The polyester coating resists corrosion in typical commercial interior conditions (non-industrial, non-marine).
