Alarm Transmission warning requirements
The 3GS system is required to comply with EN50131 8.6.1 Table 6
Europlex Conformity
en50131-1, 8.6.1, Table 6 and Annex B includes the requirements for alarm and signalling security.
This is divided into substituion and security and information security.
In the Europlex 3GS system, substitution security is acheived by a unique autodial id (0-9999). Thesys-
tem also has unique system id (0-9999). When setting up communications for a Class IV system, the
system ID and autodial ID must be assigned. It is also necessary to set the dial access to level 2 and
enter an access code.
Information security is a function of the alarm transmission equipment (ATE). If alarm transmission is
used with the alarm system, the classisfication of the equipment will influence the overall classification
of the alarm system,therefore a Class IV alarm system requires a Class IV transmission equipment to
maintain a Class IV grading.

Entry Time.
Means shall be provided to limit the exit entry time to a maximum of 45 seconds, Example: when unsetting is initiated
outside the supervised area and completed inside the supervised area.
Europlex Conformity
The Entry Exit timer on the Europlex system can be set from 0-9999. In the case of the class IV system this timer is
defaulted to 45 seconds. This timer is user adjustable but cannot be set to a time exceeding 45 seconds for class IV sys-
tems. If an installation deviates from this specification then the system is no longer class IV compliant.
In the case of a system with multiple areas, then each area exit entry time must be set to comply with the above
criteria.
