STI STI-9713 Steel Web Stopper for Photoelectric Smoke Detector
Overview
The STI STI-9713 is a patented protective enclosure designed to shield photoelectric smoke detectors from intentional damage and accidental impact in high-abuse environments. Constructed from 9-gauge steel wire with a web-like octagonal design, this stopper guards detection equipment while preserving optical sensor access and alarm signal transmission. Deploy this in commercial, institutional, and industrial facilities where detector protection is critical to both life safety compliance and equipment durability.
Compatibility
The STI-9713 features universal fit design and covers nearly all photoelectric smoke detectors on the market. No cutting or modification is required — the octagonal wire web geometry adapts to standard ceiling-mount detector housings. Suitable for controlled indoor environments only (not intended for outdoor use).
Installation Notes
Installation is quick and simple: position the protective enclosure over the detector. The patented design allows easy removal for routine detector maintenance and cleaning without tools or special procedures. Rated for controlled environments from -40° to 212°F (-40° to 100°C). Steel models feature a corrosion-resistant linear low-density polyethylene (LLDPE) coating; medical-grade 304 stainless steel variants are available for hygienic environments (hospitals, clean rooms) where corrosion resistance and washdown tolerance are required. Impact-resistant construction withstands repeated contact and abuse without deforming or losing structural integrity. Covered by a three-year guarantee against breakage in normal use.
