Best For: Commercial double-door entrances, offices, schools, warehouses and access-controlled buildings requiring 580kg holding strength per door with lock and door status monitoring.
FSH FEM6600DM Standard Double Monitored Magnetic Door Lock – 580kg per Door
The FSH FEM6600DM Magnetic Door Lock is a standard-size, double electromagnetic lock designed for commercial access control installations. It combines two magnetic locks in one surface-mounted housing, providing up to 580kg holding strength per door leaf.
This fully monitored model includes Lock Status Sensors (LSS), Door Status Sensors (DSS) and red-green status LEDs. These features allow compatible access control systems to monitor the condition of both doors and confirm whether the magnetic locks are correctly engaged.
Field-selectable 12V or 24V DC operation provides flexibility when integrating the FEM6600DM with access controllers, intercoms, keypads, fob readers, card readers, emergency release devices and other commercial security equipment.

Monitoring for Both Door Leaves
The FEM6600DM provides monitoring for both sides of the double-door opening. Monitoring outputs can be connected to a compatible access control panel, security system or building management platform.
-
LSS – Lock Status Sensor: indicates whether each magnet and armature plate are correctly engaged
-
DSS – Door Status Sensor: provides feedback about whether each door leaf is open or closed
-
Red-green LEDs: provide a visual indication of the lock status
These monitoring functions can help identify a door that has been left open, an incorrectly aligned armature plate or a magnetic lock that has not secured correctly after access has been granted.
Fail-Safe Double-Door Operation
The FSH FEM6600DM operates as a fail-safe or Power To Lock electromagnetic lock. Both doors remain secured while power is supplied and release when power is removed.
This operating method is commonly used on access-controlled commercial entrances where the doors must release following an authorised access request, request-to-exit signal, emergency release activation or loss of power.
Emergency egress, fire-system integration and backup power requirements must be considered as part of the complete access control design.
Holding Strength for Double Doors
The FEM6600DM contains two magnetic locks, with each lock providing up to 580kg holding strength when correctly installed and aligned.
This provides locking for both door leaves independently. The quoted holding force applies to each magnet and should not be interpreted as 1160kg acting on a single door leaf.
Dual-Voltage Power Requirements
The FEM6600DM can operate from either 12V or 24V DC. Because it contains two magnetic locks, the access control power supply must be sized for the combined electrical load.
-
12V DC: approximately 500mA per lock or 1A combined
-
24V DC: approximately 250mA per lock or 500mA combined
Additional allowance must be made where the same power supply also operates an access controller, card reader, keypad, intercom, emergency release device or other equipment.
No Residual Magnetism
The FEM6600DM is designed without residual magnetism. When power is removed, the armature plates release cleanly rather than remaining lightly attached to the magnets.
This provides smoother door operation, reduces unnecessary stress on the hardware and helps prevent delayed release after access has been granted.

Ideal Applications
The FSH FEM6600DM is suitable for commercial double-door openings requiring strong, monitored access control, including:
- Office building entrances
- Schools and education facilities
- Warehouses and industrial premises
- Apartment common-area entrances
- Government and council buildings
- Retail and commercial properties
- Staff-only and restricted-access areas
- Intercom-controlled double doors
- Fire-rated double doors where approved
Mounting and Door Compatibility
The FEM6600DM is designed for surface mounting across a compatible double-door opening. The required mounting arrangement depends on the door construction, frame profile and opening direction.
Compatible L, Z or other mounting brackets may be required for inswing doors or installations where the magnets and armature plates cannot be correctly aligned using the standard mounting arrangement.
Fire-Rated Installation Note
The FEM6600 Series has been tested for use on compatible fire door assemblies for up to two hours in accordance with AS 1905.1:2015. The final fire rating depends on the approved doorset, mounting method, hardware configuration and installation.
Fire-door suitability should be confirmed with the doorset supplier, certifier or manufacturer before installation.
Professional Installation Recommended
The FEM6600DM should be installed by a qualified security, access control or locksmith professional. Correct alignment between both magnets and armature plates is essential for achieving the specified holding strength and reliable monitoring.
The installer should confirm the power supply capacity, cable size, voltage selection, access controller, monitoring inputs, emergency release devices and applicable building and egress requirements.
