Frequently Asked Questions

What is a double mini magnetic lock?

A double mini magnetic lock is a compact electromagnetic locking device designed to secure both leaves of a double door. It provides electromagnetic locking across both doors from a single double lock housing.

What does DSU mean?

DSU identifies the door status monitoring version. The FR-U10004DSU includes a separate output that allows compatible equipment to monitor whether the doors are physically open or closed.

What monitoring does the FR-U10004DSU provide?

The FR-U10004DSU provides door status monitoring for door open or closed feedback. It is unmonitored in terms of engagement between the magnets and armature plates.

What is the difference between the FR-U10004 and FR-U10004DSU?

The FR-U10004DSU includes a separate door status output, allowing compatible systems to monitor whether the doors are open or closed. The FR-U10004 provides the same locking performance without this output. Both models are unmonitored in terms of lock engagement.

What is the holding force of the FR-U10004DSU?

The FR-U10004DSU provides up to 600lbs (272kg) of holding force per door leaf, giving 2 × 600lbs across the double-door installation.

Is the FR-U10004DSU fail-safe?

Yes. The FR-U10004DSU requires power to remain locked. When power to the lock is interrupted, it releases. Emergency release equipment and access controls must be correctly connected to interrupt the lock supply when required.

Has the FR-U10004DSU been fire tested?
