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 - 1

• 1800 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.

6
2. Application - 2

• 5300 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 - 3

• Accessories
• 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. Wiring

• Connecting 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

33
5. Wiring

• The 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)

34
5. Wiring - example

• 3 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. Troubleshooting

• The 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).

43
6. Troubleshooting

• The 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
