Preparation
A lamp test must be provided for all mandatory indications.
A lamp test button is available on the system manager SX-
2000Sm for its indications and the lamp test button must
be programmed on the remote microphone(s) used for the
mandatory indications.
A lamp test must also be programmed on a button of remote
microphones that provide emergency control.
All earth leakage faults are implemented in other fault
detections, therefore this separate indication is not required.
Table 1: Mandatory Indications and Controls in Access Level 1
If wanted, the mandatory indications and controls can additionally be assigned to other remote microphones or
other indication and control devices.
2.2. Options Requiring Indications and Controls in Access Level 1
the following options can be used if required. they belong to the so called options with requirements. that
means, if they will be used, then they must fulfil the requirements.
the two applicable options with requirements that require mandatory indications are certain fault indications.
the covered faults must be indicated acoustically and visible by a yellow indication (lamp/lED) in access level
1, so a fault receipt button must be provided and a lamp test must be available for all these failure indications.
It is the best to program these functions on the remote microphone that is installed adjacent to the cabinet rack
(refer to the previous chapter 2.1).

Indication
faults in VA zones
(EN 54-16, §8.4)
requirement and Preparation
requirement: a fault in each VA zone must be indicated separately, i.e. by a
separate lED per VA zone.
Assign surveillance to each speaker line of the whole emergency area.
for each VA zone, combine the speaker line faults of the same VA zone to a failure
output pattern, i.e. each VA zone must have its own pattern.
Assign each of these failure pattern to a separate fault receipt button of a remote
microphone which must be installed adjacent to the main rack in access level 1.
