The U10004DSU Double Mini Magnetic Lock or Maglock is an unmonitored electromagnetic locking solution with a separate door status monitoring output , designed for securing double doors in access control systems , door entry systems , intercoms , and electronic door security applications. Suitable for commercial, industrial, educational, healthcare, residential, and public sector environments, it provides secure and reliable locking for paired access-controlled doors.
Operating from selectable 12VDC or 24VDC , the U10004DSU delivers up to 600lbs (272kg) of holding force per door leaf , providing 2 × 600lbs across the double-door installation. Manufactured with a durable aluminium housing and electroless nickel plated steel armature plates, this double magnetic lock is designed to provide long-term reliability and consistent locking performance.
The door status output allows compatible systems to monitor whether the doors are physically open or closed. This is separate from lock status monitoring: the U10004DSU does not provide an output confirming whether the magnets and armature plates are engaged.

Frequently Asked Questions
What is a double mini magnetic lock?
A double mini magnetic lock is a compact electromagnetic locking device designed to secure double doors. It provides electromagnetic locking on both door leaves whilst maintaining a smaller overall size than a standard double magnetic lock.
What is the holding force of the U10004DSU?
The U10004DSU provides up to 600lbs (272kg) of holding force per door leaf , giving 2 × 600lbs across the double-door installation.
What does DSU mean?
DSU means door status monitoring. The U10004DSU includes a door status output that allows compatible equipment to monitor whether the doors are physically open or closed.
Does the U10004DSU provide lock status monitoring?
No. The U10004DSU is an unmonitored magnetic lock. Its door status output indicates whether the doors are open or closed, rather than confirming engagement between the magnets and armature plates.
Can the U10004DSU be used on double doors?
Yes. The U10004DSU is specifically designed for double-door installations , providing electromagnetic locking for paired door leaves alongside door status monitoring.
What does fail-safe operation mean?
Fail-safe operation means the magnetic lock 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.
What is the difference between the U10004 and U10004DSU?
The U 10004DSU includes a door status output, allowing compatible systems to monitor whether the doors are open or closed. The U10004 provides the same locking performance without this output. Neither model provides lock status monitoring.
Can the U10004DSU be used with access control systems?
Yes. The U10004DSU can be used with compatible access control systems, intercoms, door entry systems, card readers, keypads, press to exit buttons and emergency door release units. Compatible door status inputs are required to receive door open or closed feedback.
Can I use the lock without connecting the door status output?
Yes. The lock can operate without the door status output connected, but the connected system will not receive door open or closed feedback from it.
Why choose a double mini magnetic lock with door status monitoring?
It provides a compact solution for securing paired doors whilst allowing compatible systems to monitor door position. This is useful where door open or closed feedback is required alongside electromagnetic locking.
