STI Exit Button with Alarmed Shield

The STI Stopper® Station button with shield (SS-21A4EX) has a local alarm that sounds when cover is lifted, drawing immediate attention to the area. Constructed of tough polycarbonate, the unit can take hard knocks in stride and can be customized for emergency application in days.

The momentary button with shield helps prevent accidental activation, yet allows legitimate button use. If someone leans against the button or a child tries to push it out of curiosity, the shield helps prevent a false activation, eliminating unnecessary building interruptions. When legitimate use is required, user simply lifts the cover and pushes the button. When activated, the button will perform designated action (i.e. open door).

Stopper Stations are available in red, green, yellow, white or blue and offer customized wording in virtually any language. Polycarbonate is backed by a three year guarantee against breakage in normal use (one year on electro mechanical and electronic components). Button is UL/cUL Listed and ADA Compliant, shield is UL/cUL Listed.
