Complete Kit:
This comprehensive station features the high-visibility EPO button, a custom stainless steel wall plate, and the clear view safety cover for a code compliant installation.
PET/CT Safety Cover & Hardware Kit
Available separately for facilities needing to upgrade or replace protective hardware on PET/CT stations.
Stop the Guesswork.
Projects Happen Quickly — No Room for Error.
When lives and equipment are on the line, there’s no room for mistakes. Our EPO stations are engineered to meet exact specifications and prevent catastrophic failures.
The Latching Requirement
Siemens requires stations to be Press to Trip and Twist to Reset — NOT MOMENTARY. Our stations meet this exact specification.
Accident Prevention
Stations must have a protective cover to prevent accidental tripping, which can damage sensitive electronics or corrupt patient data.
Complex Circuitry
Requires multiple contacts to handle both Normally Open (120VAC for Shunt Trip) and Normally Closed (UPS emergency off jumper) circuits simultaneously.
Room-by-Room Compliance
Every location with imaging equipment — Control Rooms, Exam Rooms, and Equipment Rooms — requires an EPO button.
Critical Wiring Safety
Improperly wiring these separate circuits can cause catastrophic damage to sensitive electronics in Siemens imaging equipment and UPS systems.
The XRAY Lighting Advantage
Our stations incorporate all required safety features and include simple-to-follow instructions to get your circuit fully operational and ready for inspection immediately.

Frequently Asked Questions
Why is getting the correct EPO station so difficult?
A medical EPO must perform multiple critical duties
simultaneously when depressed:
1. Shunt Trip: Provides Normally Open (N/O) contacts that are wired in parallel to send 120VAC to the main circuit breaker shunt trip mechanism. By wiring multiple stations in parallel, any single button can complete the circuit to kill power to the imaging equipment.
2. UPS Shutdown: Provides Normally Closed (N/C) dry contacts that are wired in series to maintain the UPS safety loop. This circuit is a continuous loop that starts and ends at the UPS; our station provides the critical break in that loop. When the button is pushed, the circuit opens, immediately signaling the UPS to shut down and prevent battery back-feed.
3. Manual Reset: It must stay tripped (Latching) and cannot reset automatically.
4. Accident Prevention: It must have a protective cover to prevent accidental shutdowns. Our stations incorporate these dual-circuit requirements into one code-compliant package.
Are your EPO buttons "Momentary" or "Latching"?
All our stations are Latching (Push to Activate / Twist to Reset). Siemens Healthineers and most local building codes strictly prohibit momentary buttons for emergency power-off circuits.
