PRODUCT OVERVIEW
Stainless Steel
This heavy-duty, 1.2 mm stainless steel cover features a natural resistance to corrosion
making it an excellent choice for applications where food is present as well as water
treatment plants and correctional facilities. Available for flush mount (STI-8200-SS) or
with a conduit spacer for surface mount (STI-8230-SS, shown) applications. Easy to
install, it helps assure the smoke detector will remain operational where vandalism and
accidental damage are causing false fire alarms or high maintenance costs.
Coated Cold-Rolled Steel
Here is a protective cover for persons who prefer the strength and durability of steel but
need not be concerned with the presence of food in the area. Fabricated from 1.5 mm
cold rolled steel, it has a white corrosion-resistant polyester coating. As the stainless
steel cover, it is available for flush mount (STI-8200-W) or with a spacer for surface mount
(STI-8230-W) applications. Surface models include tamper-resistant fasteners for added
protection against vandalism. Tamperproof fastners are available for flush models.
Polycarbonate
Two models available: STI-8100 for flush mount and STI-8130 with a spacer for surface
mount. They are offered in clear, black or white polycarbonate.
