communicate, and user can type number of handset/flat. If the assingment is valid, Optima SL255 will save
it in non erasable memory. P1-P6 stands for assignment index.
ABCD Numeration
This function allows to extend the flat number with letter A-Z. When entering this function, it's similar to
NR ↔ HS Assignment, and screen prompts NR (number of flat entered on the Optima SL255) to HS
(physical address of handset) connections. ABCD numeration can only be added to number of flat, which is
used. Pressing the “7” and “9” buttons user can scroll edited flat number, and when pressed “ “, edition
screen shows. Current NO<->HS assignment is prompt below the “NOW:” inscription. If there is no ABCD
numeration for current flat number, screen prompts “----”, otherwise there are four characters (three
numbers, and one A-Z letter, eg. “010A”, “155B”, “155C”). Pressing the “7” and “9” buttons user can choose
character to edit. Four “-” characters means there is no ABCD numeration for this flat, and when user sets
“----”, and save changes, this action will erase the ABCD numeration. Setting three digits without letter at
the end (eg. “155-”, “080-”) is a ABCD numeration without letter. It can be used with mixed numeration
(when there are flats with number both – with letter and without – e.g. “010-”, “010A”, “010B”, “010C”).
After setting numeration, it is needed to confirm “ “, to save the setting.
5.1.2 Service test
Picked up handsets
When addressing all sequential handsets, the panel checks whether any of them is picked up.
One of the possible causes of incorrect operation of the system could be incorrect putting down of a
receiver of one of the handsets (or a few). To facilitate the fitters work, a feature that automatically
searches for such handsets is added. To use this option:
§ Enter the menu Settings ( code )
§ Select Service programs (confirm with „ ”)
§ Select Handsets test (confirm with „ ”)
§ Select Handsets picked up (confirm with „ ”)
Panel will check each handset (if the ranges are added, only within the assigned ranges). When a handset
with picked up receiver is found, the panel stops the search and shows on display the following message
"NUMBER XXX PICKED UP", where XXX stands for flat number. Message will be displayed until putting down
the receiver or pressing the key "#". At the end of the procedure, the panel displays a message informing
about the number of handsets with picked up receiver (if the panel detected a handset and the receiver
was not put down, and the checking was omitted with "#", the number will be more than 0).
Multi-entry system
During the test "picked up handsets", handsets line is busy - it is not possible to establish connection form
other panels. However, when a connection is already established from other panel, it is not possible to start
the test.
Wrong polarization test
Activation of this option, causes the panel, having left the menu Settings to switch to Service Mode, that
consists in generating a characteristic sound signal in the handsets line.
Some of the handset types, connected with wrong polarization, have the receiver loudspeaker connected to
the line all the time. This can also apply to correctly connected handsets, but with defective address
decoder system or other defect. Such handsets, because they impose significant load to the line, may be the
source of incorrect operation of the whole system. When starting the Wrong polarization test fitter can
detect handsets that load the line, even though they have not been addressed yet. The test consists in
starting the function and checking whether signal generated by the panel can be heard in a given handset.
