Electromagnetic Lock
Electro-Magnetic Lock Description:
Power setting and Input
The FEM5700 is an unmonitored single magnetic lock and FEM5700D is an unmonitored double magnetic
lock with dual 12 or 24 volt settings. There are no Lock or Door status sensors on these units. For wiring
instruction refer to figure 2.
The FEM5700M is a monitored single magnetic lock and the FEM5700DM is a monitored double
magnetic lock with 12 or 24 volt settings. Each magnetic lock has a built-in Hall crystal for remote
monitoring of Lock status (open or closed) through relay contacts rated at 24 VDC, 2.0 A max on
visible high luminosity backlight indicator position on the aluminum housing and a Door Status
Sensors (DSS) for remote monitoring of Door status through reed switch contact. For wiring
instruction refer to Figure 1.
The (+) lead of the power source is connected to Pins 1 (VDC +) of the terminal block and the (-) lead
is connected to Pin 2 (-). The operating switch or controlling contacts must be installed between the
power source and the magnetic lock to reduce operating time of the magnetic lock to a minimum. The
electromagnetic lock requires a filtered and regulated DC Power Source for optimal performance.
Remove the wiring cavity cover plate and check the position of the two shunts located on the PCB. A
single shunt across pins 2 and 3 will set the operating voltage to 24 volts. A shunt between pins 1 to
2 and a shunt between pins 3 to 4 sets the operating voltage to 12 volts.
These voltage shunts must be set correctly before 12 VDC or 24 VDC power is supplied to the
Electromagnetic Lock to prevent damage to the unit.

Installation Tips
Important Safety Requirements
Trouble Shooting
Maintenance
Armature Plate must remain flexible
The armature plate must be remained movable to allow surface alignment with the magnet face. The
Magnetic Lock will lose holding force without this floating alignment.
Do not trim the rubber washer mounted on the head of the armature center bolt.
Trimming rubber washers will adversely affect the release of the armature plate from the magnetic lock.
1. Apply thread-locker glue (i.g. Loctite) to the thread of the Armature-Plate-Fixing Screw (Allen-Screw) to
prevent from becoming loose.
2. Locks should be inspected at regular intervals to ascertain the safety functionality in conjunction with the
door environment.
3. The supplied Allen screws cater for maximum door-thickness of 45mm.
Problem Possible Cause Solution
Door will not lock No DC voltage to lock.
Loose wire on terminal strip.
Check power supply and wiring to
magnetic lock.
Check for voltage at terminal block of
magnetic lock.
Ensure mating surfaces are clean and in
proper alignment and the armature plate
floats freely.
Check magnetic lock for low voltage or
wrong voltage setting.
Re-wire circuit switch between magnetic
lock and power source.
Remove this diode. Voltage spike
protection is on the PCB.
Check alignment of armature plate.
Reposition reed switch; contact
manufacturer for instruction.
Bad physical contact between
armature plate and face of magnet.
Circuit switch is not between
magnetic lock and power source.
Secondary diode installed across
magnetic lock.
Misalignment of armature plate.
Reed switch located in wrong position
in magnetic block.
Reduced holding force
Delay in door release
LED Status is incorrect

Contacting surface of the Electromagnet and Armature plate must be kept free of contaminating materials.
Surfaces should be cleaned periodically with a non-abrasive cleaner. Do not spray the Electromagnet or
Armature plate surface with any lacquer chemical, this will create problems with the release of the magnetic
lock and Armature plate and might cause serious safety problems.
