The STI-4100 Break Glass Stopper from Safety Technology International delivers robust protection for large break-glass fire alarm pull stations. Like its smaller counterpart, the STI-4100 uses a clear polycarbonate shield to cover the pull station face, acting as a visible deterrent to accidental and malicious activations.
Large break-glass stations are frequently installed in commercial buildings, industrial facilities, healthcare campuses, and multi-story structures. The STI-4100 is sized to fit these larger housings, ensuring a secure, snug fit that protects the glass element while keeping the station accessible in a real emergency.
