the installer must prepare the access to certain functions in access level 1 or 2 when installing and configuring
the SX-2000 system. the details are described in the next chapters.
1.2.1. Access level 1
(citation of EN 54-16:)
Parts in access level 1 must be visible and/or accessible by member(s) of the general public or persons having
a general responsibility for safety supervision who might be expected to investigate and initially respond to a
fire alarm or a fault warning.
All mandatory indications shall be visible at access level 1 without prior manual intervention (e.g. the need to
open a door). manual controls at access level 1 shall be accessible without special procedures.
Indications and manual controls that are mandatory at access level 1 shall also be accessible at access level 2.
(Explanation:)
usually the cabinet racks containing the SX-2000 system are installed in a separate (engine) room. the access
level 1 requirements are fulfilled when persons having a general responsibility for safety supervision (...) have
access to this room.
1.2.2. Access level 2
(citation of EN 54-16:)
the entry to access level 2 shall be restricted by a special procedure. the procedure may require
- mechanical keys,
- a code of at least 3 manual sequential operations, or
- access cards.
Parts in access level 2 must be visible and accessible by persons having a specific responsibility for safety and
who are trained and authorized to operate the VAcIE in the:
- quiescent condition,
- voice alarm condition and
- fault warning condition.

A lockable room is access level 2 when only persons having a specific responsibility for safety and who are
trained and authorized to operate the VAcIE can unlock it. An emergency microphone can be installed inside a
lockable (wall-mount) box to fulfil this requirement.
