The FEM5700 is an unmonitored single magnetic lock and the FEM5700D is an unmonitored double magnetic lock with 12 or 24 Volt settings.
The FEM5700M is a monitored single magnetic lock and the FEM5700DM is a monitored double magnetic lock with 12 or 24 Volt settings. Each monitored magnetic lock has a built-in Hall Effect Sensor for remote monitoring of Lock status (LSS).
The devices have a patented highly visible high luminosity Light Panel and Door Status Sensor (DSS) for remote monitoring of the door status through a reed switch contact as well as a Lock Status Sensor (LSS). The monitored devices come with a Patented Anti-Tamper-Security-Plate as standard to prevent hostile attacks on the dome-nut-fixing bolt of the Armature Plate. All FEM5700 Series Electro Magnetic Locks come with a lifetime warranty and have no residual magnetism.
