2. INDICATIONS AND CONTROLS IN ACCESS LEVEL1
2.1. Mandatory Indications and Controls in Access Level 1
All mandatory indications and controls must be provided and installed in access level 1. The minimum
requirement is to provide them all on one cabinet rack or when a system is divided in several cabinet racks,
then they can be distributed over several ones if these are installed adjacent to each other.
Two of the mandatory indications are available on the system manager SX-2000SM, the other mandatory
indications must be realised on a remote microphone which must be installed adjacent to the cabinet rack
(on front or side of the rack or on the wall next to the rack). If this remote microphone is programmed to be an
emergency microphone, then it must not contain any function that has to be in access level 2 (refer to chapter
3).
The mandatory indications are listed below. Each stated indication requires its separate indicator (LED).

Preparation
implemented in SX-2000SM, RM-200SA and RM-200SF
- available on the SX-2000SM (no preparation required);
- can be programmed on a remote microphone:
prepare a fault pattern including all faults of each alarm-
related system elements and speaker lines (including also
the faults which require a separate indication) assign this fault
pattern to one fault receipt button.
The system fault (CPU hang-up) is displayed on the SX-
2000SM.
This fault can be programmed on a remote microphone by
assigning all faults related with the VX-2000DS or VX-3000DS
(basically by all units where the VX-2000DS' or VX-3000DS'
are connected to) to one fault receipt button.
Prepare a fault pattern containing all SX units where the VX-
2000DS or VX-3000DS is connected to.
Assign this pattern to one fault receipt button.
This fault can be programmed on a remote microphone by
assigning all amplifier faults and SX-2000 unit's (SX-2000SM,
SX-2100AI, SX-2000AO, SX-2100AO, SX-2000CI and SX-
2000CO) faults to one fault receipt button.
Prepare a fault pattern containing all above mentioned SX
units and all amplifiers.
Assign this pattern to one fault receipt button.
Program a fault warning for every port of the Ethernet switches
of the IES-3000 series used for SX-2000 unit connections.
Connect their fault outputs to control inputs of the SX-2000
system.
Program these control inputs for an external fault. Make a fault
pattern for these faults including the activation of a common
control output.
Connect this control output with a control input and set this to
be an external fault input.
Make a fault pattern for this fault input and assign it to a fault
receipt button of a remote microphone.
