NT-SS102-EN STI

The STI NT-SS102-EN is an indoor, pneumatic push-button Stopper® Station designed for access control, egress, and emergency door-release applications. Molded from a durable, high-impact green polycarbonate shell, the faceplate features a prominent, raised "EXIT" label to provide clear visibility for building occupants.
This model utilizes a specialized, all-mechanical pneumatic adjustable timer that requires no external electrical power to manage the door release window. The timing cycle can be field-adjusted directly from the back of the switch mechanism to keep a door unlocked anywhere from 2 to 60 seconds after a single push.
It comes equipped with one set of Form C (SPDT) dry contacts rated for heavy-duty switching at 10 Amps @ 125/250 VAC. The device functions reliably across an extreme temperature range of -40°F to 250°F (-40°C to 121.1°C), is fully ADA compliant, and is UL/cUL Listed.
