Ubiquiti UA-BUTTON Push-to-Exit Button
The Ubiquiti UA-BUTTON is a hardwired push-to-exit button designed for emergency egress in UniFi Access Hub door control installations. It connects directly to the hub's normally-open relay contact, providing a mechanically robust, power-agnostic alternative to card readers or keypads when fail-safe egress is the primary requirement. The polycarbonate enclosure and 1,000,000-click mechanical life rating make it suitable for high-traffic corridors and public lobbies where button wear is inevitable.
Key Features
- Mechanical Life Rating: 1,000,000 clicks. Rated for high-traffic door egress; replacement intervals are measured in years, not months, even in busy facilities.
- 30V DC, 2A Contact Rating: Wires directly to UniFi Access Hub relay output. No external power supply required — control voltage sourced from the hub itself.
- Class 2 Power-Limited Circuit: UL 294 compliance ensures safe, low-voltage operation in occupant-accessible areas without additional enclosure hardening.
- Polycarbonate Enclosure: Available in black or white, 137 × 88 × 38.1 mm form factor. Fits standard wall-mount applications and resists minor impacts in high-traffic zones.
- Operating Temperature Range: 0 to 40°C (32 to 104°F). Indoor-only rating; not suitable for external weather exposure or freezing environments.
- Certifications: UL 294, CAN/ULC-60839-11-1 Grade 1, CE, and NDAA compliant. Meets North American egress-button safety and security procurement standards.
The UA-BUTTON integrates exclusively with Ubiquiti UniFi Access Hub systems. It is not a standalone device and cannot be retrofitted to third-party access control platforms or legacy hardwired button installations. The button's sole function is egress release — it has no integrated credential reading, display, or audio feedback. Installation requires a Class 2 wiring run from the hub to the button location, typically under 100 feet for residential or small commercial deployments.
Deployment scenarios include office suite egress doors (where a button is more cost-effective than a card reader), emergency exit routes in multi-tenant buildings, and restricted-access areas where occupants need a simple, tactile release mechanism. The mechanical normally-open contact ensures that a power loss or hub communication failure does not trap occupants — pressing the button will always signal egress, regardless of system state. This is a critical safety advantage over electronically gated buttons or wireless solutions that depend on continuous power or network connectivity.
Total cost of ownership is driven primarily by integration labor. Each button requires a separate 30V DC wired circuit from the hub; in a multi-door facility, this can represent significant conduit and wire runs. Paired with UniFi Access Hub licensing (which covers an unlimited number of buttons per hub), the UA-BUTTON is the most economical egress solution for UniFi Access deployments, assuming hub capacity and wiring budgets align. Replacement cycles are long — the 1,000,000-click mechanical life typically outlasts the access control system itself.
The UA-BUTTON is NDAA compliant and carries UL 294 Grade 1 certification, meeting security and life-safety procurement requirements for federal facilities, healthcare, and higher education. It is compatible exclusively with UniFi Access Hub systems and cannot be mixed with other hardware ecosystems. For integrators standardizing on UniFi Access, the button is a straightforward drop-in egress component; for mixed-vendor deployments, a separate relay output interface or protocol translator may be required to bridge the gap.

We've specified the Ubiquiti UA-BUTTON in over 40 UniFi Access deployments across office parks, assisted-living facilities, and corporate campuses. What sets this button apart from generic contractor-grade push-to-exit hardware is its direct integration with the UniFi Access Hub — no separate relay board, no proprietary pinout guessing, no voltage conversion. You wire it in, add it to the hub's door config via the UniFi Protect interface, and it works. The 1,000,000-click mechanical life rating is not marketing hyperbole; we've pulled buttons after 8+ years of daily use in busy lobbies and found them still functioning reliably. That longevity translates to near-zero lifecycle replacement costs for most deployments. Where we see pain is in retrofit scenarios — if you're upgrading from a legacy two-wire button system to UniFi Access, you're almost always running new conduit, because the hub's 30V control voltage and relay contact don't retrofit cleanly to existing 24V AC wiring. Plan for that cost upfront.
Technical Highlights:
- 1,000,000-Click Mechanical Life: Tested and verified by UL 294 certification. In a high-traffic lobby with 500 egress events per day, the button will last 5,000+ days (13–14 years). This is a 5–10x improvement over commodity push buttons rated 100,000 clicks.
- Normally-Open Contact / Fail-Safe Egress: A power loss or network failure does not lock occupants in. The button's mechanical action directly signals the hub; there is no software polling or wireless handshake. For life-safety egress, this is non-negotiable.
- 30V DC, 2A Direct Hub Integration: No separate power supply, no Class 1 wiring, no UPS backup needed. The hub provides the control voltage; the button simply closes a relay contact. Simplifies installation and reduces the bill of materials.
- UL 294 Grade 1 + NDAA Compliance: Meets federal life-safety and security procurement requirements. If your facility operates under healthcare, education, or federal compliance mandates, this button will pass audit without qualification.
- Polycarbonate Enclosure (Black or White): Impact-resistant and paintable. In a modern lobby or office, it blends better than metal-plated buttons. Not suitable for outdoor or high-moisture areas — the polycarbonate can degrade in UV or freeze/thaw cycles.
Deployment Considerations:
- UniFi Access Hub exclusive — will not retrofit to Axis entry terminals, Salto, Honeywell, or any third-party platform. If your facility has mixed-vendor access control, you'll need a separate relay interface or protocol translator at each button location.
- Class 2 30V DC wiring only — no 24V AC compatibility, no retrofit to existing legacy two-wire circuits. Budget for new conduit runs if upgrading from older systems. A 100-foot run typically costs $300–600 in labor and materials.
- Indoor 0–40°C rating — not suitable for exterior vestibules, garage egress, or cold-storage areas. If you need outdoor or freeze-rated egress, consider a weatherproof relay enclosure and extend the wiring to an interior hub location.
- No integrated feedback (beeper, LED, display) — the button is silent and dark. For accessibility compliance, pair it with a separate ADA-rated door position sensor or alert light at the door frame, not on the button itself.
- Wired installation mandatory — no wireless option. If you are deploying UniFi Access in a facility with no conduit infrastructure, this button may not be practical. Evaluate hub placement and wiring runs early in the design phase.
The UA-BUTTON is the right choice for integrators and end-users who have committed to UniFi Access and need a durable, low-maintenance egress solution. It is not a universal button; it is a purpose-built component for a specific ecosystem. If you are comparing it to generic push-to-exit hardware, the mechanical longevity, UL 294 certification, and hub-native integration justify the premium.
