1. General• Installing an electromagnet is particularly easy.

There is no need to be a specialist installer of locks.

• The magnet attracts the armature plate and holds it tight. That is the reason why the plate has to be fitted as close as possible to the magnet.

• A magnet correctly installed, never affects its surroundings because it is a closed magnetic field. When used correctly, there is no interference with nearby installations and no health risks.

• The electromagnetic locks EM are particularly well treated to resist corrosion. But care must be taken to protect the electrical parts and connections.


1. General• There is NO residual magnetism on the EM magnets!

It means that as soon as the power is switched off, the lock is released immediately and there is no residual holding.

• The EM electromagnets do not require special maintenance. It is important not to clean them with an abrasive or a solvent.


2. Application - 11800 Newton

• Small magnet designed for light but reliable and secure locking. Particularly well adapted for locking glass doors, or medium internal doors of modern offices

3000 Newton

• Intermediate range of magnets meeting most of the middle range security needs. It is recommended for the majority of internal doors as they do not have to be resistant to heavy attacks.


2. Application - 25300 Newton

• Basic electro-magnet, specially designed to combine a maximum holding force with low power consumption. This magnet is used for all high security access where efficiency and security cannot be comprised.

The Shearlock

• This is a hybrid magnet mixing a classical electro-magnet and an electric lock. The shearlock is the only solution for fitting a flush magnet on a swinging door.


2. Application - 3Accessories

• The mounting brackets are made from extruded anodized aluminium. They adapt

the magnets for all kinds of doors.

4. Installation (see steps on next slide) • Start first by fitting the armature plate (do not

tighten the screw too much) and install the magnet next.

• After you fit the plate, power the magnet with a 9 volt battery. It will stick to the plate and you will have your two hands free to mark the outlines of the magnet with a pencil on the frame.

• After checking that the system is working correctly, slightly unscrew the armature plate and put a drop of thread locking compound into the thread of the screw.

• Do a final check on the movement of the plate.

5. WiringConnecting an electromagnet is simple. Nevertheless,

it can be useful to carefully read the following notes: • The minimum voltage for the power supply must be

12/24 Volts DC minimum (tolerance of –0% + 20 %).

• This voltage should always be measured on the magnet connector and not on the connector of the power supply.

• An electric cable has a loss of voltage directly proportional to its length and inversely proportional

to its cross-section as explained here after:


5. WiringThe basic formula is: Rw = (r x L) / S

Rw : resistance of the wire

r : specific resistance determinate by the type of wire (for copper 0,0175 ohm)

L : length in meter (attention, there are 2 wires. Do not forget to multiply by 2!)

S : cross-section of the wires in mm2

And the ohm law: V = R x I V: voltage (volts)

R: resistance (ohm)

I: Current (ampere)


5. Wiring - example3 magnets are installed at 25 meters from the power supply! They

are powered in 12 VDC and each of them has a consumption of 500 Ma. The wire has a section of 0,5 mm2.

• We have then a cable length of 50 m (there are 2 wires) and a total consumption of 1,5 A (1500 mA)

• A: Calculation of the resistance of the wire:

• R = (0,0175 x 50) / 0,5 = 1,75 ohm

• B: Calculation of the voltage drop:

• V = 1,75 x 1,5 = 2,62 volts

• The magnet must have as a minimum its nominal voltage on the connector, which in this case 12 VDC.

• As the cable will cause a voltage drop of 2,62 volts, it will be necessary to adjust the power supply to 14,62 volts minimum.

6. TroubleshootingThe armature plate is too tight:

• This is a common error when you install a magnet for the first time. The installer is concerned when he sees that the plate is loose and he overtightens the screw, to crushing the rubber washer and clamping the whole set together. However, a door has an angular motion, and it is the flexibility of the armature plate that compensates for this movement. The more flexible the plate, the better the system will function (see: installation of the armature plate).


6. TroubleshootingThe voltage on the magnet connector is too low :

• This is another classic problem of first-time installation. The electromagnetic locks have to be powered in 12 VDC or 24 VDC minimum. If the voltage is lower, the holding force will be also lowered and the monitoring will not function properly.

• Attention: The magnets are supplied with a factory setting to 24VDC. If you power in 12VDC, do not forget to change the voltage selection
