STI STI-8100-BK Smoke Detector Protective Enclosure
Overview
The STI-8100-BK is a flush-mount polycarbonate protective enclosure designed to shield smoke detectors from intentional and accidental damage in high-traffic institutional and commercial environments. The sealed design prevents vandalism while maintaining detector functionality and accessibility for service. This model fits standard smoke detector mounting scenarios where physical protection is a priority without requiring surface-mounted conduit routing.
Compatibility
The STI-8100-BK accommodates existing smoke detector installations in flush or recessed mounting configurations. The enclosure is compatible with standard detector geometries and does not interfere with detector optical or thermal sensing. The 2.75-inch opening allows seamless integration with typical ceiling-mounted detector footprints. Consult the detector manufacturer's installation documentation to confirm clearance and airflow requirements when combining with specific models.
Installation Notes
The STI-8100-BK installs flush into drywall or plaster surfaces using standard mounting hardware (included). For unstable or uneven mounting surfaces, STI offers the optional STI-8171 backplate to distribute load and ensure secure seating. The polycarbonate construction remains transparent, allowing visual inspection of detector status without removal. No wiring, power, or network connectivity is required — the enclosure is a passive protective component. Slot geometry is designed to prevent insertion of tools or implements that could trigger false alarms or damage optical sensors. Installation time is typically under 15 minutes per unit once the mounting location is prepared.
