Lock switch contact
Target group of this documentation
This documentation is intended for use by specialists only. All work described in this document
is to be performed by experienced professionals with training and practice in the assembly
and installation of door locks in connection with electronic components. Safe and proper
assembly of this electronic door lock is not possible without expert knowledge.
Intended use
• The lock switch contact is suitable for use in striker plates or locking rails with Q-adjustment
in combination with KFV multi-point locks with hook bolts or pin-hook-bolt combination.
• The lock switch contact is used in systems, e.g. alarm systems that provide feedback on the
status of the door lock.
• The lock switch contact is suitable for installation in timber, aluminium, steel and PVC front
doors in residential and public buildings.
• All assembly and electrical installation work must be carried out according to our assembly
and installation instructions.
• Use the lock switch contact only when it is in a technically sound condition. Do not modify
the unit's components in any way.
• Use the lock switch contact only with genuine accessories from KFV.
• Switching voltage 30 V DC, 0.2 A
Improper use
• When used in steel frames and /or doors made of timber, aluminium and PVC with steel
reinforcement, it must be ensured that there is sufficient clearance to the magnetic parts. This
area must be milled if necessary.
• Application of mechanical force to the housing e.g. during assembly, could damage the
casing of the reed switch. Installation using heavy tools (e.g. hammers) is strictly prohibited!
• The magnet loses its field strength if it is subjected to intense heat, vibration or mechanical
processing.
• Wiring the unit incorrectly can irreparably damage the component.
• Operating voltage >30 V DC; switching current > 0.2 A
• Temperatures outside the specifications in the technical data

Technical information on magnetic contacts
Please observe the technical specifications on page 14. These specifications are max. values and
may never be exceeded, not even for brief periods of time. Therefore, under no circumstances may
continuity testers with in-built bulbs be used for the testing/inspection of lock switch contacts. The
current flowing through the lock switch contact in these devices is so high that the contact could
be damaged irreparably. Only use the control device magnetic switch ZUPG0010 for testing or
inspection purposes. (Fig. 6)
Lock switch contacts based on reed contact are sensitive to excessive voltage or currents. As reed
contacts open their contact extremely quickly, very high self-induction voltages are generated when
switching off inductive and capacitive switching devices such as e.g. relays. The lock switch contact
must be protected here.
Contact protection
To avoid overloading the switch, we recommend the provision of a protective circuit for the
switching of lamp loads, capacity or inductivity. The electrical values (current, voltage and output)
defined in the technical specifications of the magnetic contacts are applicable for purely ohmic
loads. Usually, however, the loads are combined with inductive or capacitive components or
lamp loads are switched. In all these cases, the magnetic contacts must be protected against the
occurrence of peak voltages and currents.
When is a contact protection necessary?
• VdS burglar alarm systems are designed for the activation of alarm contacts and do not
require any further contact protection. Contact protection is appropriate if alarm contacts
are operated outside units/systems that are not designed for reed contacts.
Alarm contacts loaded with capacitive or inductive switching devices must be safeguarded with
a contact protection.
Below you will find some recommendations of how magnetic contacts should be wired for different
types of load in order to prevent wear and tear or premature failure.

Capacitive loads
In contrast to inductive loads, increased inrush currents could occur with capacitive loads and lamp
loads, which could lead to interference - including contacts possibly welding together.
When charged capacitors are switched (e.g. also cable capacitors), a sudden discharge occurs,
the intensity of which depends on the capacity and length of the supply line to the switch to be
regarded as series resistor. The discharge current peak is reduced to a greater extent by a series
resistor to the capacitor.
Its dimensions are determined by the possibilities of the relevant circuit. In any case, it should be
as large as possible to limit the discharge current to an admissible value. These considerations also
apply to the charging of capacitors.
Lamp loads
It is a well-known fact that light bulb filaments when cold, i.e. when switched off, have a resistance
that is approximately one tenth of the resistance when burning. This means that on activation, even
for a short time, a current flows that is ten times higher than the current when the lamp is static. This
10-fold inrush current can be reduced to an admissible level by means of a current-limiting resistor
connected in series. Another possibility is the parallel connection of a resistor to the switch which
continually pre-heats the deactivated lamp filament to an extent that it is not quite yet glowing. Both
types of protection are associated with a loss in performance.

Direct current
For switching of direct current, a free-wheeling diode must be connected in parallel to the load. The
polarity must be accomplished out to ensure that the diode locks at the normal operating voltage
and, on opening the switch, inversely short circuits occurring voltage peaks.
+
Alternating current
An electric arc attenuator must be used when switching to alternating current. In general this is an
RC element, which is connected in parallel to the switch and therefore connected in series with the
load.

Magnetic switch test unit ZUPG0010
You can check the function of the magnetic contact and the NO or NC contacts with the aid of the
magnetic switch ZUPG0010.
To do this, connect the three cables of the magnetic contact to the connections 1-3 with the aid of
the test terminals provided. When disconnected, the two LEDs of the NC contact light up.
If a metal bar is now pushed between the magnetic contact, the two LEDs of the NO contact light
up.
