xxxxxx is 2-6 numerals). After dialling of confirmation characters NLLW reply by
its serial number (DTMF tones).
Second way (
with confirmation
) is detection that call was succesfull
only by dial confirmation characters (*xxxxxx, where xxxxxx is 2-6 numerals).
This way is most reliable but requires trained people in service department
(they must be able insert confirmation characters when call is pick up), or at
service department must be used evaluation software.
After dialling of confirmation characters the NLLW reply by its unique
serial number. By this way is detected where from is coming a call even when
more NLLW is installed behind PBX. In this case is not possible detect it by
CLIP because all NLLW have the same CLIP due the same telephone line use
for outgoing calls.
2.2.6 Machine room connection
Connection between machine room and NLLW is special case which has
absolut priority. The reason is that during machine room communication is
disconnected telephone line. The NLLW accept machine room call as incoming
, it means you can programm the unit , control relay,.. The call is not time
limited as same as not possible hang up.
Possibility to make machine room connection is only when you use option
box named
„PREPOJ“ and via connection of third wire (telephone line has 2
wires And third is for NLLW controlling). Wires connection is displayed on
picture 8, page 15. The call is activated by picking up of phone. The NLLW
picks up immediatelly (is active). This status is indicated by both indicators (
green and yellow) light up. You can make voice communication. The call
duration is until hang up phone in machine room.
2.2.7 Incoming call
Incoming call is coming from outside to NLLW. After extension dialling or
land line number where is NLLW connected the NLLW is ringing and after
preprogrammed number of rings (parameter 51) the NLLW picks up And you
can speak to lift cabin.
Exceptional is first 10sec, where is additionally possible insert "# and
service password" (
parameter 44
), to enter programming mode.
When jumper "SERVIS" on NLLW basic board is closed you are
automatically going to programming mode when call is picks up. ( without
service password). It is usefull when you forget service password and by this
way you can programm the new one. Do not forget disconnect jumper after
programming . Jumper is on the basic board (picture 1 page 7).
Incoming call is detected by green indicator. It is possible control relay. It
is possible voice communication. After dialling of confirmation characters the
NLLW
returns seriál number. The incoming call is only the way how programm
the NLLW by telephone (tone dial DTMF).
