Each of the four branch lines can be connected to up to two apartment
station units in parallel as shown in the table below.
See the applicable installation diagrams for connections.
PROGRAMMING
For inspection purposes, each four-port decoder produced by URMET
DOMUS is programmed with the four call codes 9996, 9997, 9998 and
9999.
The apartment station call codes programmed in a decoder are
numbers between 1 and 9999. Code format will depend the system’s
installation TYPE as follows.
•
In TYPE 1 systems without secondary entrance panels,
format will be: “NNNN”
•
In TYPE 1 systems with secondary entrance panels,
format will be: “SNNN”
•
In TYPE 2 systems, format will be: “SSNN”
•
In TYPE 3 systems, format will be: “SSSN”
IMPORTANT
In systems with secondary entrance panels, the four stored codes
must all have the same prefi x: S for TYPE 1, SS for TYPE 2 and
SSS for TYPE 3.
Once the programming method has been selected as illustrated in the
appropriate section, proceed as follows:
1) Press the programming pushbutton : LED will go on.
2) Using the keypad on the calling device (i.e., an entrance module or
guard door switchboard station), enter the code for the apartment
station connected via terminal A) and press the call button . If a
digitizer is used, press the call key for this apartment station. LED
will fl ash and then remain on.
3) Subsequently enter the codes for the 21 st , 31 st and 41 st apartment
stations as directed in step 2. After the 41
st
code is entered, LED
will fl ash for a few moments and then go off.
If fewer than four numbers are to be stored in memory, press the
programming pushbutton after entering the fi rst, second or third
number, as applicable.
NOTICE
To ensure that system maintenance can be effi ciently performed,
it is ESSENTIAL that the codes programmed in each four-port
decoder be written down on the memorandum label (2) provided
inside the decoder cover.
DECODER PROGRAMMING METHODS
Decoders can be programmed in three ways:
1) Directly on the system after connecting and supplying the latter,
using either an outdoor station (entrance module or digitizer) or a
guard door switchboard station.
This operation must be carried out by two people who communicate
either by cellular phone or by using the system’s outdoor and indoor
stations. One person will use the outdoor station or switchboard
station, while the other works at the decoders. After programming
each decoder, calls can be made from an outdoor station to check
that all functions operate correctly.
2) Directly on the system as above, but disconnecting the entrance
module and connecting it directly to the various four-port decoders
using an appropriate programming cord (Ref. 826/104). With this
method, programming can be carried out by a single person. In
this case, checks on correct operation will obviously have to be
performed afterwards.
3) At the workshop prior to installation, using an outdoor station (or
the switchboard station) and the power supply unit. In this way, all
decoders can be programmed at the same time, and subsequently
installed in the appropriate locations.
After programming all decoders, carry out a fi nal check by turning off
power supply units for at least 5 seconds. Then turn power supply units
back on and send calls to check the programmed codes.
OPERATION
The four-port decoder must be programmed with the codes assigned
to the apartment stations associated with it. These codes are resident
on an EEPROM memory which guarantees that they are retained even
with power off.
During operation, the code emitted by a calling device (i.e., an entrance
module, digitizer or guard door switchboard station) is recognized
by the decoder, which causes the associated apartment station
doorphone to ring for the entire period that the call button is held down,
and activates the voice channel. The conversation can last up to ten
minutes if no calls are made to another user.
After this 10 minute period, or if the call is interrupted by a call
to another user, the decoder sends a brief intermittent tone to the
connected apartment station to inform the user that the call has been
interrupted. The doorphone apartment station and/or video doorphone
apartment station is provided with two special keys which can be
used to send “Door Lock Release” and “Call Switchboard” (optional)
command signals. Only one door lock release signal is needed, even
if the system includes several outdoor stations, each with an electric
lock: actuating the door lock release key will open the electric lock only
at the outdoor station from which the call was made.
