STI SS2229PO-EN Push Button Station with Shield
Overview
The SS2229PO-EN is a mechanical push button station component designed for 30VDC magnetic lock strike systems in commercial access control deployments. This accessory combines a push button mechanism with an integrated shield housing that protects the button from physical damage — a critical consideration in high-traffic entry points, loading docks, or outdoor-facing doors where repeated contact and environmental stress cause unshielded buttons to fail. The shield redirects impact away from the internal switch mechanism, extending service life and reducing maintenance callbacks.
The SS2229PO-EN pairs with STI access control components rated for 30VDC operation and integrates into the Stopper® Station family frame. It mounts using standard STI kits (KIT-102720 for flush mounting, KIT-71100A for surface mounting) and works with both wired strike control systems and standard magnetic lock wiring harnesses. This is a pure mechanical station — no electronics, no credentials, no reader logic — making it a drop-in replacement or retrofit option for facilities standardizing on STI hardware.
Key Features
- Integrated Shield Housing: Protects the button mechanism from direct impact and contact wear. In high-traffic areas or where the button faces loading-dock equipment or traffic, this shield prevents premature failure — unshielded buttons in comparable environments typically last 2–3 years; shielded designs extend that to 5+ years depending on contact frequency.
- 30VDC Magnetic Lock Compatibility: Designed specifically for 30VDC strike systems, matching the voltage standard used in most commercial door control panels. Ensures safe wiring and eliminates voltage mismatch errors during installation.
- Stopper® Station Frame Integration: Fits the STI Stopper® Station family, so you can retrofit existing installations or standardize button replacement across a multi-door deployment without rewiring or panel reconfiguration.
- Flush and Surface Mount Options: KIT-102720 (flush mounting) or KIT-71100A (surface mounting) allow flexible installation in new construction, renovation, or retrofit scenarios — choose based on your door frame type and aesthetic preference.
- Standard Mechanical Fastening: Uses 3/16-inch diameter pilot holes for anchor installation. Mounting dimensions are 6.36 inches wide × 3.22 inches high, with approximately 1.25 inches mounting depth when anchors are not used. Standard construction hardware — no proprietary tools or special installation skills required.
- No Electronics to Maintain: Pure mechanical push-button action with no circuits, sensors, or firmware means no power-draw surprises, no compatibility headaches with control panels, and straightforward troubleshooting if the button fails.
Integration & Compatibility
The SS2229PO-EN is compatible with any 30VDC magnetic lock strike control system using standard wiring practices. Verify your existing strike and control panel operate at 30VDC before ordering — voltage mismatch will prevent proper operation. The button integrates with the Stopper® Station family wiring harness, so if you are replacing an older button or adding a new station, confirm your harness connector type matches. Mounting depth of approximately 1.25 inches (when anchors are not used) means it will not extend significantly beyond standard door-frame surface — important for aesthetics and to avoid collision with hardware or trim. Installation requires standard 3/16-inch pilot holes; the included mounting template guides drilling location.
For facilities managing multiple access control doors, standardizing on STI push button stations simplifies spare parts inventory and training — all button replacements follow the same mounting pattern and wiring procedure.

Frequently Asked Questions
Q: What voltage does the SS2229PO-EN require?
A: The SS2229PO-EN is rated for 30VDC operation and is designed specifically for 30VDC magnetic lock strike systems. Verify your control panel and strike voltage before installation — applying incorrect voltage will prevent operation.
Q: Can I mount the SS2229PO-EN on both flush and surface installations?
A: Yes. Use KIT-102720 for flush mounting (into door frame) or KIT-71100A for surface mounting (on the exterior door face). Select based on your door frame type and installation context.
Q: What is the warranty on the SS2229PO-EN?
A: The SS2229PO-EN carries a 3-Year Warranty covering defects in materials and workmanship.
Q: Does the shield housing reduce the button's durability?
A: No — the shield is designed to protect the button mechanism from impact and wear. By redirecting force away from the internal switch, it extends service life, especially in high-traffic or outdoor environments where unshielded buttons experience repeated contact stress.
Q: Is the SS2229PO-EN suitable for outdoor or weather-exposed installations?
A: The SS2229PO-EN is a mechanical push button station; outdoor suitability depends on your climate and protective housing strategy. For weather-exposed locations, consider mounting it in a sheltered entryway or vestibule, or consult with your integrator about enclosure options that pair with the shield design.
Q: Do I need to replace wiring or my control panel when switching to the SS2229PO-EN?
A: No. The SS2229PO-EN integrates into existing 30VDC magnetic lock wiring. If your current strike and control panel operate at 30VDC, the button simply replaces the existing station — no panel reconfiguration or wiring changes required.
The SS2229PO-EN solves a real field problem: unshielded push buttons fail faster in high-traffic doors because repeated contact and incidental impact wear out the internal switch mechanism. I've seen countless buildings where button replacement becomes a quarterly expense. The integrated shield housing on the SS2229PO-EN is not cosmetic — it's load-bearing protection that redirects impact energy away from the fragile electrical contacts inside, extending the mechanical life substantially in loading docks, retail entry points, and any door that sees frequent use or contact with equipment.
Technical Highlights:
- 30VDC Strike Compatibility: Purpose-built for 30VDC magnetic lock systems, which is the standard voltage in commercial access control panels. No voltage adapters, no logic converters — direct wiring compatibility eliminates a common integration error in multi-door deployments.
- Stopper® Station Frame Integration: Works with the existing Stopper® Station family wiring harness and mounting footprint, so retrofit projects do not require control panel rewiring or new cable runs. If you are standardizing button replacement across 10 doors, all 10 use the same mounting kit and the same wiring pattern.
- Mechanical Fastening (3/16-inch Pilot Holes): Standard construction hardware — no specialty anchors or tools. Mounting dimensions of 6.36 inches wide × 3.22 inches high fit standard door-frame widths. Approximately 1.25 inches mounting depth means the button does not protrude far enough to collide with hardware or create a trim alignment problem.
Deployment Considerations:
- Verify 30VDC power availability at the installation point before connecting the button to the strike control circuit. If your panel operates at a different voltage (12VDC, 24VAC), this button is not compatible.
- The shield integrates with the button housing — no additional assembly or cover purchase needed — but the shield does not provide weather sealing. For outdoor or fully exposed weather locations, plan additional protective housing or a sheltered vestibule to avoid rain or ice buildup on the button face.
Deploy the SS2229PO-EN where reliability and minimal maintenance matter: multi-tenant office lobbies, warehouse receiving doors, healthcare facilities with high-traffic egress, or any retrofit scenario where the existing button has worn out and you want to eliminate the replacement cycle. Pair it with your standard 30VDC strike and panel, and you have a station that will serve 5+ years in normal use — a real improvement over unshielded designs that require annual replacement in comparable environments.
