Protective Wire Guard for Flush Detectors

The STI Stopper STI-9609 is a UL Listed wire cage designed to shield flush-mounted smoke detectors from vandalism and accidental impact. It serves facilities managers and building owners who need durable protection for life-safety devices in high-traffic or vulnerable areas.

Steel Construction with Corrosion Resistance

Built from 9-gauge steel wire with a polyester coating, the cover resists rust and physical abuse without impeding detector operation. The open web design allows smoke to reach the sensor freely while the robust frame absorbs knocks and tampering attempts.

Fits 4.6 by 8.3 Inch Flush Units

This model covers detectors measuring 4.6 inches in height and 8.3 inches in width. Installers must verify these exact dimensions against the target device; the guard will not suit surface-mounted units or detectors outside this footprint.

Questions about this item

How is the STI-9609 cover installed over a flush-mounted smoke detector, and what step is often missed?

Mount the steel wire frame directly over the detector using the existing ceiling screws; the step often missed is ensuring the 9-gauge wire grid sits flat so smoke can still enter the detector vents.

What maintenance or replacement will the STI-9609 need over its lifetime?

The corrosion-resistant polyester coating on the 9-gauge steel wire is designed to last; inspect occasionally for coating damage and replace the cover only if the wire mesh is bent or corroded.

What physical limit of the STI-9609 shows up first under sustained impact or vandalism attempts?

The 9-gauge steel wire mesh will deform before the mounting points fail; the cover measures 8.3 inches wide by 4.6 inches high, so heavy repeated blows can bend the grid out of shape.
