Class III
Outdoor (sheltered or
indoor extreme
conditions)
Indoor (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%
and 95% without being subject to condensation.
Class IV
Outdoor (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.
Table 2 - Environmental Classes EN50313-1
EN 50131-1 establishes four levels of user access that define the ability of users to access system
components and controls:
Level 1
Access by anyone.
Level 2
Access by the user (e.g. an operator).
Level 3
Access by the maintainer.
Level 4
Access by the manufacturer.

IMQ mark
IMQ is a Notified Organism, or a structure authorised by the national government authority
and notified to the European Commission. The Notified Organism is responsible for
evaluating - with skill, transparency, neutrality, and independence - the conformity of
products and services with the conditions established by the European directives. These verifications are
carried out upon specific request of the economic operators, who pay all costs.
IMQ is the only Italian body that certifies security systems, attesting to the conformity of devices and
components with security specifications and performance contained in the relative CEI and EN standards.
Moreover, it conducts the tests required by other directives applicable to security systems, like those on
electromagnetic emissions, on wireless frequencies, and wireless communications.
MEDEA certifications
The MEDEA 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.
Certified notification configuration:
Outdoor Siren + PSTN card encoded SP2, DP1 or GSM card encoded SP4, DP2 or Ethernet port encoded
SP6, DP2.
