STI SS2421EM-EN Stopper Station Push Button with Stopper Station Shield, "Emergency" Label, Turn-to-Reset Button, Blue

Quick, reliable emergency control is essential for effective security and lockdown procedures. The Safety Technology International SS2421EM-EN Stopper Station push button is built for confident, low-voltage activation in schools, healthcare facilities, retail sites and corporate campuses. The Turn-to-Reset button prevents accidental rearming and makes post-incident recovery deliberate and auditable. A protective polycarbonate shield guards the switch from damage and unintended presses, keeping your monitoring and surveillance systems accurate when seconds matter.

Designed for system integrators, the Stopper Station accepts interchangeable gold-plated N.O./N.C. contact blocks (rated up to 6A @ 600VAC or 1A @ 250VDC) and supports 230V AC / 30V DC inputs, enabling flexible connection to access control, alarm panels and building automation. UL/cUL listing and ADA compliance simplify code requirements while stainless steel construction withstands daily use. Ideal for indoor emergency and lockdown installations where reliability, compliance and ease of use are priorities.
