This unique and patented device has helped prevent theft and vandalism to access controls, digital keypads, push buttons, smaller manual pull stations and much more around the world for over 30 years, without restricting access to protected device.
The STI 6545Y consists of a clear, tamperproof, super tough polycarbonate cover, frame and yellow conduit spacer that is designed for surface mount applications. Additional models are available with a built-in warning horn that sounds when cover is lifted to gain access to the pull station (see STI 6605Y). The STI 6545Y offers excellent protection against physical damage (both accidental and intentional).
