Zones Test

Two different tests are available in the Zones Test sub-menu:

●

single zone test that displays the signal level of the selected zone (depending on the

value of the installed resistors)

●

a multiple zone test that displays the status (balanced/unbalanced) of groups of 8

zones (see Figure 28). Press

to scroll to the next group of 8 zones (if installed on

the system). A dot (.) indicates a balanced zone, while a plus sign (+) indicates an

unbalanced zone.

Figure 28.

Zones testing

Outputs Test

Similar to the Zones Test, it is possible to test each output. Select Outputs Test to display the

status of groups of 8 outputs (installed on the system). Press

to scroll to the next group

of 8 outputs. Press

to select an output. Press ENT to change the status of the selected

output.

Modules Acquisition

The Modules Acquisition feature is used when one or more modules are removed from the

system, or when the installer wants to update the bus configuration. When this feature is

selected, the CU erases all the modules stored into the internal memory, and starts

scanning the bus. Each module that responds to the CU is stored into the CU modules table.

5.6.7

Timer events

This option is not yet implemented.

5.6.8

Date and time

This sub-menu (Figure 29) is used to modify the system date and time. When this sub-menu

is selected, both the date and the time have to be modified (reset). Press ENT to modify the

date and time values. The cursor starts to blink on the first digit of the month. Enter the

correct value and then press ENT in order to modify the day, year, hours and minutes.
