PREFACE
CONFORMITY WITH EN50131-1
The EN50131-1 standard calls for the installation of a grade four intruder alarm system, based on the level of risk determined in
function of the type of environments, of the value of the goods to be protected, and the typical intruder expected.
Grade 1: Low risk
It is expected that the intruders have little knowledge of intrusion alarm systems and have a limited range of tools that can be easily
obtained. It is indicated for premises with contents of low value.
The system is simple and equipped with external and/or internal acoustic alarms, optical warnings, and eventually a telephonic
communicator to vocal messages to other people.
Grade 2: Average-low risk
It is expected that the intruders have limited knowledge of intruder alarm systems and use some tools and portable instruments (for
example, a multimeter).
It is the minimum level that can be recognised by insurance companies.
It involves mostly residential and commercial premises of low value.
The system can be connected with a Security Service.
Grade 3: Average-high risk
It is expected that the intruders have knowledge of intruder alarm systems and have a full range of tools and portable electr onic
equipment.
It is indicated for commercial and industrial premises, as well as for residential premises with a high value.
The system is usually connected with a Security Service.
Grade 4: High risk
To be used when security has the priority over all other factors. It is expected that the intruders have the skills and resources to plan a
detailed intrusion and have a complete set of tools available, including the means for substituting components of an intruder alarm
system. This is indicated for particularly sensitive premises, for example, banks.
ATTENTION!
The grade of an intruder alarm system is the one of its lowest grade component.
The EN50131-1 standard requires that the components of the intruder alarm system are suitable to be used in one of the following
environmental classes, where Class I is the most moderate and class IV is the most severe.
Environmental class I
– Indoors
Environmental influences normally present in closed environments, when the temperature is well-controlled (ex: in a residential or
commercial property).
NOTE
: The environment should not be subject to condensation and the temperature should vary between +5°C and +40°C with an
average relative humidity of about 75%.
Environmental class II
– Indoors – General
Environmental influences normally present in closed environments, when the temperature has not been controlled (ex: in corridors,
other spaces or stairways where condensation may form on windows and in unheated areas used as a deposit or in warehouses where
heating is intermittent).
NOTE
: The environment should not be subject to condensation and the temperature should vary between -10°C and +40°C with an
average relative humidity of about 75%.
Environmental class III
– Outdoors – Sheltered or indoors under extreme conditions
Environmental influences normally present outdoors when components of the intruder alarm system are not totally exposed to
atmospheric agents or indoors, when the environmental conditions are extreme.
NOTE:
The environment should not be subject to condensation and the temperature should vary between -25°C and +50°C with an
average relative humidity of about 75%. For 30 days a year it is expected that the relative humidity will vary between 85% an d 95%
without being subject to condensation.
Environmental class IV
– Outdoors – General
Environmental influences normally present outdoors, when the components of the intruder alarm system are completely exposed to the
elements.
NOTE
: The environment should not be subject to condensation and the temperature should vary between -25°C and +60°C with an
average relative humidity of about 75%. For 30 days a year it is expected that the relative humidity will vary between 85% and 95%
without being subject to condensation.
The MP500 intruder alarm system was certified at IMQ - SECURITY SYSTEMS laboratories in conformity with European standards
EN 50131-1, EN 50131-3, and EN 50131-6 - Grade 2 or 3 - Environmental class II - general indoors.
The grade depends on how the system is constructed and/or configured.
With an ATS4 communicator connected, the MP500/8 and MP500/16 control panels respect notification options A and B
– Grade 3.
With the telephone line connected, the MP500/4N, MP500/8, and MP500/16 control panels can respect the notification options A and B
- Grade 2.
