Overview
The Ubiquiti UACC-Lock-Bolt-Secure is a fail-secure electric drop bolt lock designed for UniFi Access door control installations. It uses 12V DC power and is intended for single wooden or metal doors with door-frame recess mounting. The lock includes an embedded door position sensor (DPS) for monitoring door status.
Operation
The fail-secure design keeps the bolt locked when power is removed and releases the lock when electrical power is applied. Ubiquiti specifies NO/COM/NC relay wiring for connection to a UniFi Access Hub. The lock supports a maximum current draw of 900mA at 12V DC ±10%.
Door Monitoring
An embedded door position sensor provides a dry-contact output for door-status monitoring. The DPS reports an open door when DPS/+ and DPS/- are open and a closed door when those contacts are shorted. The contact is rated for up to 30V DC and 0.5A.
Mounting and Construction
The lock is designed for door-frame recess mounting. The lock body measures 132 x 30 x 42 mm, while the supplied door frame plate measures 82 x 32 x 3 mm and the door plate measures 204 x 33 x 3 mm. The lock body and plates use aluminum alloy construction.
Key Features
- Fail-secure electric drop bolt operation
- 12V DC ±10% operating voltage
- Embedded door position sensor for door-status monitoring
- NO/COM/NC relay wiring for UniFi Access Hub installations
- Red and green LED status indication
Applications
The UACC-Lock-Bolt-Secure is intended for controlled single-door access installations where the locking mechanism must remain locked during a power loss. It can be used with UniFi Access Hubs for electronically controlled entry on compatible wooden or metal doors.
DC Supplies Product Note
Because this is a fail-secure lock, the locking behavior differs from Ubiquiti's fail-safe bolt model: the UACC-Lock-Bolt-Secure remains locked without power and requires power to release.
