Introduction

This European Standard is for opening contacts (magnetic) used as part of intrusion and hold-up

alarm systems (I&HAS) installed in buildings. It includes four security grades and four environmental

classes.

The purpose of an opening contact (magnetic) is to detect a displacement of a door or window from

the defined closed position. The opening contact comprises two separate parts, the active connection

between which is at least one magnetic field. Separating the two parts disturbs the connection and

produces an intruder signal or message.

The number and scope of these signals or messages will be more comprehensive for systems that are

specified at the higher grades.

This European Standard is only concerned with the requirements and tests for opening contacts

(magnetic). Other types of detectors are covered by other documents identified in the EN 50131 series

and in the EN 50131-2 series.

1 Scope

This European Standard provides for security grades 1 to 4, (see EN 50131-1) specific or non-specific

wired or wire-free opening contacts (magnetic), and includes the requirements for four environmental

classes covering applications in internal and outdoor locations as specified in EN 50130-5.

A detector shall fulfil all the requirements of the specified grade.

Functions additional to the mandatory functions specified in this European Standard may be included

in the detector, providing they do not influence the correct operation of the mandatory functions.

The two separate parts of the opening contact (magnetic) shall be referred to in the body of this

European Standard as the detector.
This European Standard does not apply to system interconnections.

All terminals and means of mechanical and electronic adjustments shall be located within the

detector’s housings.

The tamper security requirements for each grade of detector are shown in Table 1.

---------------------- Page: 13 ----------------------
SIST EN 50131-2-6:2009
EN 50131-2-6:2008 – 12 –

If the detector can be opened, a tool shall be required to open the unit. For grades 2, 3 and 4

detectors all covers giving access to components that could adversely affect the operation of the

detector shall be fitted with a tamper detection device that shall generate signals or messages in

accordance with Table 2. It shall not be possible to gain such access without generating a tamper

signal or message or causing visible damage. Sealed contacts do not require the means to detect

access to the inside of the detector.
4.5.3 Detection of removal from the mounting surface

A detection device shall be fitted that generates a tamper signal or message in accordance with

Table 2 if the detector is removed from the mounting surface. Operation of the tamper device shall not

be compromised by external means. This device shall activate before access can be gained to it.

4.5.4 Magnetic field interference

When the detector is mounted in accordance with the manufacturer’s instructions and is subject to the

presence of an external magnetic field generated by the interference test magnets specified in

Annex A and applied to the faces of the detector according to Annex F, the detector shall either:

a) be immune to any influence by the interference test magnets and continue to operate normally

with the make and break distances not exceeding twice those specified in accordance with 4.3.1,

b) generate an intrusion, and/or tamper, and/or fault, and/or other independent signal or message in

accordance with Table 2 when the make or break distances exceed twice those specified in

accordance with 4.3.1. These signals or messages may be generated either on application of the

interference test magnet or when the corresponding magnet has returned to its original installed

position.

NOTE The signals or messages generated by a grade 4 detector are intended to be used by the I&HAS to positively identify an

attempt to sabotage the detector through magnetic interference.
4.5.5 Matched coded pairs

A grade 4 detector shall consist of a matched pair of switch component and corresponding magnet.

The means of matching shall have a minimum of 8 differs. It shall not be possible to determine the

specific pair identity by visual inspection of the detector.
The probability of the use of each code shall be equal.
4.6 Electrical requirements
4.6.1 Grade dependencies

The requirements of 4.6.2 to 4.6.6 only apply to detectors having external power to operate the

components of the detector.

4.6.2 Detector current consumption

The detector's quiescent and maximum current consumption shall not exceed the figures claimed by

the manufacturer at the nominal input voltage.
4.6.3 Slow input voltage change and input voltage range limits

The detector shall meet all functional requirements when the input voltage lies between ± 25 % of the

nominal value, or between the manufacturer's stated range limits if greater. When the supply voltage is

raised slowly, the detector shall function normally at the specified range limits.

4.6.4 Input voltage ripple

The detector shall function during the sinusoidal variation of the input voltage by ± 10 % of nominal, at

a frequency of 100 Hz.
4.6.5 Input voltage step change

No signals or messages shall be caused by a step in the input voltage between nominal and maximum

and between nominal and minimum.
4.6.6 Total loss of external power
This subclause applies to detectors that require an external power supply.

This does not include any applied voltage to a purely reed based switch detector.

An intrusion signal or message shall be generated by the total loss of the supply voltage.

No generation of a message or signal is required when this total loss of external power condition is

detected by the CIE due to system design, e.g. bus based systems.
4.6.7 Low supply voltage
This subclause applies to detectors that require an external power supply.

NOTE This does not include any applied voltage to a purely reed based switch detector.

A fault signal or message shall be generated when the minimum level of voltage that is required for

the detector to operate reliably is compromised according to the specification of the manufacturer.

No generation of a message or signal is required when this low power condition is detected by the CIE

due to system design, e.g. bus based systems.
4.6.8 Interconnection Integrity

The detector shall provide a means to enable the I&HAS to monitor the integrity of the interconnection.

Where the interconnecting cable or wire is provided with the detector, means shall be provided to

permit the monitoring of this interconnecting cable in accordance with EN 50131-1 (e.g. a tamper loop

or end of line resistor built into the body of the detector).

NOTE This requirement may be fulfilled either by the detector itself or by suitable system design.

4.7 Environmental classification and conditions
4.7.1 Environmental classification

The environmental classification is described in EN 50131-1 and shall be specified by the

manufacturer.
