3. INDICATIONS AND CONTROLS IN ACCESS LEvEL 2
Basically all alarm related manual controls and the fault reset control must be in access level 2.
3.1. Mandatory Control in Access Level 2
All faults except two ones in the SX-2000 system are reset automatically when the fault is not available anymore.
the faults of amplifiers and short circuits on the speaker line require a fault reset control to re-enable the
operation of them (before the reason of the fault should be removed). therefore the fault reset button must be
available but has to be in access level 2.
No.

Preparation and requirements
- fault reset button on system manager SX-2000Sm (preparation in chapter 8, for
the operation refer to the text below this table);
- programming the fault reset function on a remote microphone requires to install
the remote microphone in access level 2 (refer to the chapter 3.3.1 installation
place);
- programming the fault reset function on a control input requires to install the
connected switch to be in access level 2 (e.g. in a lockable box)
Table 3: Mandatory control in access level 2
Since the system manager SX-2000Sm shall be installed in access level 1 but also containing a fault reset button,
its operation was modified to meet the access level 2 requirements (refer to chapter 8 also). It is necessary to
proceed a 3-step sequential procedure to make a fault reset on this button:
1. push the fault reset button start for a duration between 0.1 - 1.5 seconds and release it
2. push the fault reset button within 2 seconds after the previous push start for a duration between 0.1 - 1.5
seconds and release it
3. push the fault reset button within 2 seconds after the previous push start for a minimum duration of 2
seconds and release it
When the pushing procedure does not cause the fault reset, then the done action was probably wrong. then
wait for 2 seconds after the last button release and start the sequence again.
