Ubiquiti UACC-LOCK-STRIKE-SECURE-15MM Fail-Secure Electric Strike Lock
Overview
The UACC-LOCK-STRIKE-SECURE-15MM is a fail-secure electric strike lock purpose-built for access control systems integrated with UniFi Access hubs. It combines zinc alloy construction with stainless steel latches to deliver 1,200 kg (2,645 lb) holding force—meaning the lock stays engaged if power fails, a critical safety feature for secure perimeter doors, server rooms, and high-security storage areas. Powered by 12V DC at 400mA, it operates across industrial temperature ranges (-10 to 60°C) and handles both wooden and metal door frames via recess mounting.
Key Features
- 1,200 kg holding force: Substantial mechanical resistance to forced entry; equivalent to supporting two-thirds of a loaded car. This matters for doors protecting valuable equipment or restricted areas where break-in deterrence is non-negotiable.
- Fail-secure operation: Remains locked when power is lost—critical for emergency lockdown scenarios. Contrast this with fail-safe strikes, which release on power loss; choose fail-secure for high-security applications where you cannot afford unauthorized access during an outage.
- 12V DC, 400mA power draw: Low current consumption means integration into standard UniFi Access power budgets without additional supply infrastructure. A single 12V rail can support multiple strikes if wired in parallel.
- Dry-contact door status reporting: Integrated reed switch provides real-time confirmation of door lock state (open/closed) back to the UniFi Access Hub, enabling audit trails and automated alerts if a door is propped or held open abnormally.
- Zinc alloy and stainless steel construction: Resists corrosion in humid or salt-spray environments; survives aggressive cleaning chemicals common in food processing, pharmaceutical, and healthcare facilities.
- Short and long front plate options: Two mounting profiles accommodate standard and non-standard door frame geometries, reducing custom fabrication during retrofit installations.
- NDAA and international compliance: FCC, IC, and CE certifications; NDAA Section 889 compliant, meeting federal procurement requirements for government and defense contractor deployments.
- Recess mounting for wooden and metal frames: Flexible installation reduces cost compared to surface-mounted solutions; compatible with both traditional wood-stud framing and modern metal door frames.
Integration & Compatibility
The UACC-LOCK-STRIKE-SECURE-15MM wires directly to UniFi Access Hub controllers via 12V/NO (red) and 12V/COM (black) terminals. Door status contact is rated 30V DC, 0.1A maximum, allowing integration into access control recording systems that log every strike event. Operating environment tolerance spans -10 to 60°C and 5–90% noncondensing humidity, supporting indoor lobbies, climate-controlled server rooms, and partially enclosed parking structures.

When to Choose a Different Model
The UACC-LOCK-STRIKE-SECURE-15MM is optimized for standard single-door, fail-secure scenarios. If you need fail-safe operation (where the lock releases on power loss to allow emergency egress without manual override), or if your door frames require surface mounting rather than recess installation, evaluate alternative strike models in the Ubiquiti access control line. For multi-door or high-throughput entryways (e.g., turnstiles, gates), consider modular access control solutions with graduated strike options.
Frequently Asked Questions
Q: Does the UACC-LOCK-STRIKE-SECURE-15MM remain locked during a power outage?
A: Yes. Fail-secure operation means the lock stays engaged when power is lost. This protects the space behind the door even if the electrical supply is interrupted.
Q: What is the current draw, and will it strain a UniFi Access power supply?
A: The strike consumes 400mA at 12V DC (4.8W). A standard UniFi Access Hub power allocation supports multiple strikes on a single supply without overload.
Q: Can I use the UACC-LOCK-STRIKE-SECURE-15MM on both wooden and metal door frames?
A: Yes. Recess mounting accommodates both frame types. The short and long front plates adjust for frame-depth variations.
Q: Does the strike lock provide door open/close status back to UniFi Access?
A: Yes. A built-in reed switch (dry contact, 30V DC, 0.1A max) reports lock state to the UniFi Access Hub, enabling real-time monitoring and historical logs of door activity.
Q: Is the UACC-LOCK-STRIKE-SECURE-15MM NDAA compliant?
A: Yes. It is NDAA Section 889 compliant and carries FCC, IC, and CE certifications, meeting federal and international procurement standards.
Q: What temperature range does this strike lock support?
A: Operating range is -10 to 60°C (-14 to 140°F) at 5–90% noncondensing humidity, suitable for indoor secure facilities and climate-controlled storage areas.

The UACC-LOCK-STRIKE-SECURE-15MM is straightforward engineering—a fail-secure strike that stays locked when power dies, which is exactly what you want on a secure perimeter. The 1,200 kg holding force is substantial, and the 400mA draw is light enough that you won't need supplemental power infrastructure if you're deploying across multiple doors on a single UniFi Access controller.
Technical Highlights:
- 1,200 kg holding force with fail-secure operation: Mechanical energy stays locked in a blackout. This is not a convenience—it's a requirement for server rooms, high-value storage, and restricted-access facilities where you cannot accept loss of access control during a power event.
- 12V DC, 400mA consumption: Negligible current draw means you can wire multiple strikes in parallel without triggering power-budget constraints on a UniFi Access Hub supply. Compare this to fail-safe strikes that sometimes pull 600–800mA and require dedicated 12V rails.
- Dry-contact door status (30V DC, 0.1A): Reed switch feedback loops back to the controller, enabling continuous audit logging and real-time alerts if a door is held open or propped. Critical for compliance audits in healthcare, financial, and government facilities.
- Zinc alloy + stainless steel latches: Resists salt spray and aggressive cleaning agents. If your facility uses hospital-grade disinfectants or operates in coastal environments, this material selection matters—cheaper plated strikes corrode within 12–18 months.
Deployment Considerations:
- Recess mounting requires careful frame preparation; verify frame depth matches the short or long plate before ordering hardware. Retrofit installations sometimes need frame shimming to achieve proper strike alignment.
- Fail-secure means the door will not unlock during a power loss. Ensure your facility has manual override keys and egress protocols documented for occupants. OSHA and ADA may require failover lighting or panic hardware on emergency exits.
Deploy this strike on any secure single-door application where power-loss lockdown is a feature, not a bug: server rooms, secure storage, vaults, and restricted-access corridors in government buildings. Pair it with Ubiquiti UniFi Access hubs for integrated credential management and logging. Avoid it for emergency exits or public spaces where fail-safe (release-on-power-loss) is legally required.
