STI SS2188EX-EN Indoor/Outdoor Surface w/ Horn Pneumatic, Illuminated, Stopper Station with EMERGENCY EXIT, Green

Deliver fast, confident emergency signaling where security and clear user action matter most. The Safety Technology International SS2188EX-EN Stopper Station is a surface-mounted pneumatic emergency exit and lockdown button engineered for schools, healthcare, retail and other supervised environments. Its pneumatic timer requires no electricity to operate, providing a dependable 2–60 second timed response and repeatable performance ideal for monitored security and surveillance systems. When the protective cover is lifted, an audible horn sounds locally while the illuminated LED bar (12–24 VAC/VDC) provides clear visual status — reducing false alarms and calling immediate attention. ADA-compliant and UL-recognized, the SS2188EX-EN includes 1 N.O. and 1 N.C. contacts rated for 10 A resistive loads to integrate easily with access control, alarm panels and monitoring networks. Finish options and raised EMERGENCY EXIT messaging make it simple to deploy in public-facing areas.
