Showstopper 4 is the heart of your emergency stop system.

Built from industrial safety-rated components, Showstopper 4 ensures all motion halts at the press of a button. To operate, every Stagehand must receive a green-light signal from Showstopper.

Showstopper Base

Where it all begins. The mothership. E-stop Grand Central Station. Showstopper 4 Base is a rack-mountable device that powers the emergency-stop contactors of up to 10 Stagehands.

Showstopper Base also connects up to three accessory devices to expand your emergency stop topology. Add in Remote e-stop buttons, a Showstopper Consolette, Showstopper Hub, and lots more.

All this packed in a snug 2U rack-mountable case.

All Clear for Take Off

If your stage automation was an Apollo space mission, the Showstopper 4 system is mission control giving a Go/ No-Go for take off.

A green light means you're good for take off. A No-Go aborts the mission and nothing moves.

Who Goes There?

Showstopper ID

Is the e-stop button in the trap room pressed? How about the grid? No need to wonder (or wander), Showstopper 4 can tell you the status of every emergency stop button in your venue.

Each button has a unique, configurable identifier to take the guesswork out of recovering from an emergency stop. Every ID can be named in Spikemark then grouped and organized however you desire to make it quick and easy to pinpoint the problem.

Big Show?
