Overview

Protect fire alarm pull stations and reduce costly false activations with the Safety Technology International STI-1150NR Stopper II protective cover. This flush-mount, polycarbonate hood provides rugged, weather-resistant protection (IP54) for indoor and outdoor installations while maintaining a low-profile appearance that suits commercial, educational, medical and public facilities. If the cover is lifted, an integrated self-contained horn delivers a piercing 95 or 105 dB alert at one foot to immediately draw attention, deter tampering and support alarm monitoring and security response. The STI Stopper II is UL/cUL Listed for reliable, code-compliant performance and is sized to fit standard pull stations (approx. 6.2 in H x 5 in W x 3.2 in D). Ideal for security, surveillance and life-safety systems, this no-label model keeps protected devices discreet without sacrificing deterrence. Specify the STI-1150NR for projects that require dependable vandal and false-alarm prevention—order now or contact your supplier for bulk pricing and installation guidance.
