Best For: Double commercial doors, office entrances, retail premises and access-controlled entry points requiring slimline, fail-safe magnetic locking without monitoring outputs.
FSH FEM4300D Slimline Double Magnetic Door Lock – Non-Monitored, 280kg, 12/24V DC
The FSH FEM4300D is a slimline double electromagnetic door lock designed to secure pairs of access-controlled doors. It incorporates two magnetic locks, with each magnet providing a holding strength of up to 280kg.
Designed for fail-safe, Power To Lock operation, the FEM4300D supports field-selectable 12V or 24V DC input and releases the doors when power is removed. Its slimline surface-mount housing makes it suitable for commercial entrances where available mounting space and appearance are important.
This is the non-monitored model and does not include Lock Status Sensor, Door Status Sensor or LED status indication. For these monitoring functions, consider the FSH FEM4300DM monitored double magnetic lock.

Designed for Double-Door Entrances
The FEM4300D combines two electromagnetic locks within a single double-door housing. Each magnet operates with its own armature plate, allowing both door leaves to be secured as part of the same access control system.
Its slimline construction is well suited to office foyers, retail entrances, commercial buildings and controlled staff areas where a low-profile double magnetic lock is required.
Fail-Safe Magnetic Locking
The FSH FEM4300D operates in fail-safe or Power To Lock mode. Electrical power is applied to hold the doors secure, and the locks release when power is removed.
This operating method allows the lock to be integrated with compatible access control systems, emergency exit devices and fire-alarm interfaces. Emergency release and egress requirements must be considered as part of the complete door installation.
Non-Monitored Configuration
The FEM4300D is designed for installations where lock and door status feedback is not required. It does not include:
- Lock Status Sensor (LSS)
- Door Status Sensor (DSS)
- Red and green lock status LED
If these monitoring functions are required, the corresponding monitored model is the FSH FEM4300DM.
Dual-Voltage 12/24V DC Operation
Field-selectable 12V or 24V DC operation provides flexibility when integrating the FEM4300D with access control panels, intercom systems, card readers, keypads and professional access control power supplies.
The complete double lock draws approximately 1A at 12V DC or 500mA at 24V DC. The power supply should be sized to accommodate the magnetic lock, access controller and any other connected devices.
No Residual Magnetism
The FEM4300D is designed without residual magnetism after power is removed. This helps the doors release cleanly and reduces unnecessary resistance when users open the doors following an authorised access request or emergency release.

- Access-controlled internal double doors
Fire-Rated Door Applications
The FEM4300D has been tested for use on compatible fire-door assemblies for up to two hours in accordance with AS 1905.1:2015. Approval depends on the complete doorset, mounting arrangement and fire-door manufacturer requirements.
Suitability must be confirmed before installing the lock on a fire-rated door.
Installation Note
The FSH FEM4300D should be installed by a qualified security or access control technician. Door alignment, mounting brackets, power supply capacity, cable protection, emergency release devices and fire-alarm integration must be considered during system design.
An appropriate double L&Z bracket may be required where the door and frame configuration does not support standard direct mounting.
