Smoke Detector Guard STI-9605

The Safety Technology International STI-9605 is a steel wire guard designed to shield indoor smoke detectors from vandalism and accidental impact. It mounts directly onto a surface and fits over the detector without a back plate. The white coated finish suits standard ceilings and walls.

Replaces Exposed Installations

This guard upgrades a bare detector that is vulnerable to knocks, tampering or deliberate damage in public or high-traffic areas. The jump is worth it when a building code, insurance requirement or risk assessment calls for physical protection of the life-safety device. MEA approval and UL listing confirm it meets recognised safety standards.

Fits Surface-Mount Builds

The open-back design slips over the existing detector and secures with the included mounting hardware, requiring no rewiring or enclosure modification. It frees the detector from physical abuse while leaving sensor vents unobstructed. Operating tolerance from -40 to 250 degrees Fahrenheit ensures the guard survives extreme ambient conditions.

Questions about this item

How much wall space does the 7 1/8 in wide guard need for surface mounting?

The guard measures 7 1/8 inches wide, 7 1/8 inches high and 4 1/2 inches deep, so allow at least that footprint plus clearance for the mounting hardware on a flat wall or ceiling.

What is the installation step people often miss when fitting the STI-9605 guard?

The open-back design requires the smoke detector to be mounted first; the guard then slides over it and is screwed to the surface through the supplied brackets, not directly to the detector.

Will the white coated steel wire need repainting or replacement after years in a hot attic?

The 9-gauge coated steel wire is rated for continuous exposure from -40 to 250 degrees F, so the finish is designed to withstand extreme heat without degrading or requiring recoating.
