Ubiquiti UACC-Lock-Strike-Safe-8mm Fail-Safe Strike Lock
Overview
The Ubiquiti UACC-Lock-Strike-Safe-8mm is a fail-safe electric strike lock designed for single wooden or metal doors in UniFi Access installations. It supports an 8 mm lock slot depth and provides 227 kg (500 lb) of holding force.
The strike lock operates from 12V DC and uses continuous electrical power to remain locked. When power is interrupted, the lock releases, providing the fail-safe behavior specified for this model.
Lock Operation
The UACC-Lock-Strike-Safe-8mm uses a fail-safe locking configuration. When powered, the strike remains locked. When power is removed, the lock releases.
Ubiquiti specifies the lock for a single wooden or metal door with door-frame recess mounting.
Electrical Specifications
The strike lock operates at 12V DC ±10% and draws 200mA ±10%. The lock uses normally closed and common wiring for its fail-safe operation.
For UniFi Access Control Hubs, Ubiquiti specifies that the fail-safe strike lock connects to the NC and COM terminals of the hub's powered relay.
Door Status Detection
The integrated door status interface uses a dry contact. When the door is open, DPS/+ and DPS/- are open; when the door is closed, DPS/+ and DPS/- are shorted. The door status contact is rated for a maximum of 30V DC and 0.1A.
Construction and Mounting
The lock body is made from zinc alloy, while the front plate and latches are stainless steel. The lock body measures 112 x 21 x 28 mm.
Two front plate sizes are specified: a short front plate measuring 152 x 24.5 x 3 mm and a long front plate measuring 250 x 25 x 3 mm. The lock is designed for door-frame recess mounting.
Key Features

DC Supplies Product Note
Because this is a fail-safe strike lock, it releases when electrical power is interrupted. The access control design should therefore account for the desired door behavior during power loss.
