STI (SS2039PS-EN) Red indoor/outdoor flush turn-to-reset (illuminated) stopper station with fuel pump shut down label english

The STI SS2039PS-EN is a red, illuminated, turn-to-reset Stopper Station with a “FUEL PUMP SHUT DOWN” label in English — a complete switch station, not a pull-station cover. First, an operator pushes the recessed button. Then the integrated illumination confirms activation. As a result, the wired switch contacts open or close the connected fuel-pump shutdown circuit at gas stations, fueling depots, and similar fuel-dispensing sites.

What SS2039PS-EN is built for

NFPA 30A and local fuel-handling codes require an accessible emergency shutoff for the fuel dispensers at any service station or fleet fueling site. However, a plain industrial pushbutton can be mistakenly activated or fail to draw an operator’s eye in an emergency. Therefore, the Stopper Station combines a recessed button, a bright illuminated head, a turn-to-reset action that resists casual reset, and a clearly labeled cover so the station survives daily public exposure and still functions reliably when needed.

What the “PS” suffix means and how to pick the right label

The STI 2039 series ships under multiple label SKUs that share the same station hardware. Specifically: PS = FUEL PUMP SHUT DOWN (this SKU); ES = EMERGENCY STOP; EX = EMERGENCY EXIT; PO = EMERGENCY POWER OFF; LD = LOCKDOWN. Therefore, the only practical difference among these SKUs is the screened label — wiring, contacts, and mounting are identical. As a result, specify the PS variant when the station controls a fuel dispenser shutdown circuit; specify the PO variant when it controls a building-wide emergency power-off; specify the ES variant for machine emergency stops.

Application context

Fueling sites typically wire the SS2039PS-EN to the emergency stop input on the dispenser controller or the dispenser circuit’s shunt-trip breaker. However, the Stopper Station is a switch only — it carries no panel-side intelligence. Therefore, the connected circuit determines the actual shutdown behavior. In addition, the SS2039PS-EN is NOT a fire alarm pull station and is not UL Listed for fire alarm initiating-device service.
