Description
LOX EM3500D Double Door Electromagnetic Lock | 560kg | 12/24VDC | Fire Rated
The LOX EM3500D is one of Australia's most trusted electromagnetic locks for double-door applications. Delivering 280kg of holding force per magnet (560kg combined), it is engineered for commercial, institutional, and industrial facilities where reliable, fire-rated access control is non-negotiable. Zero residual magnetism ensures instant door release the moment power is removed.
Key Features

Frequently Asked Questions
What is the difference between the EM3500D and the EM3500DM?
The EM3500D is the non-monitored version — ideal where lock or door status feedback is not required. The EM3500DM adds Lock Status Sensing (LSS), Door Status Sensing (DSS), and LED indicators for integration with access control panels that require door monitoring.
Is the LOX EM3500D suitable for fire-rated doors?
Yes. The EM3500D is fire rated to up to 4 hours in accordance with Australian Standards, making it suitable for installation on fire-rated double doors on compliant egress routes.
Can the EM3500D be used on glass double doors?
Yes, when paired with compatible LOX glass door brackets or armature holders. Refer to the LOX Accessories Catalogue (available in the Downloads section above) for suitable bracket options.
What does “zero residual magnetism” mean?
It means the maglock releases the door instantly when power is cut, with no lingering magnetic force. This is critical for egress compliance and ensures the door does not stick after the lock is de-energised.
Does CCTV Guru ship the LOX EM3500D Australia-wide?
Yes. We ship to all states and territories across Australia, including metro and regional areas.
