826
MAXIMUM NUMBER OF APARTMENT
STATIONS PER DECODER CHANNEL
Each four-port decoder (826/23) can be connected to a maximum of 4
apartment stations, one per branch.
NOTE: Two doorphones or video doorphones of any type (with the
exception of Explorer video doorphones) can be connected
directly in parallel to each of the four branches. If several
doorphones or video doorphones must be connected in parallel
to the same branch, see the applicable URMET DOMUS
installation diagrams.
Single-port decoder (826/14) is designed for installation in the
doorphone casing, while single-port decoders for the Scout monitor
(1204/94) are installed on the associated bracket.
Where single-port decoders 826/14 and 1204/94 are used, it is
not possible to connect two apartment station doorphones or video
doorphones in parallel. Where this type of connection is required, a
ring repeater relay with supplementary power supply or transformer
must be installed.
NOTE: ALL CODES USED IN A SYSTEM MUST BE UNIQUE. NEVER
ASSIGN TWO IDENTICAL CODES IN ORDER TO MAKE
TWO APARTMENT STATIONS RING AT THE SAME TIME.
TYPE SETTINGS AND ERROR WARNINGS
In any given system, all entrance panels and the guard door
switchboard station, if provided, must be programmed with THE SAME
TYPE DIGIT.
If an entrance panel is programmed for a different installation TYPE than
that used for the system as a whole, it will generate an error warning.
Entrance modules and digitizers will generate an audible warning, while
a visual warning will also be displayed at entrance modules. The audible
warning consists of a continuous tone, while the visual warning will
consist of one of the error messages detailed below:
E 12 - Module confi gured for TYPE 1, system confi gured for TYPE 2
E 13 - Module confi gured for TYPE 1, system confi gured for TYPE 3
E 21 - Module confi gured for TYPE 2, system confi gured for TYPE 1
E 23 - Module confi gured for TYPE 2, system confi gured for TYPE 3
E 31 - Module confi gured for TYPE 3, system confi gured for TYPE 1
E 32 - Module confi gured for TYPE 3, system confi gured for TYPE 2
The error warning will continue until one of the following events occurs:
•
A key is pressed on the incorrectly confi gured entrance panel.
•
The incorrectly confi gured entrance panel receives a message with
TYPE identical to its own.
•
The 30 minute time-out ends.
Following system installation, check that all entrance modules have
been correctly programmed with the same TYPE digit. To do so,
proceed as follows:

Following system installation, check that all entrance modules have
been correctly programmed with the same TYPE digit. To do so,
proceed as follows:
•
Call an apartment station from any of the entrance panels in the
system.
•
Check that NONE OF THE REMAINING entrance panels generates
an error warning

•
Repeat this procedure for ALL entrance panels in the system, in
each case checking that no error warnings are generated at ALL OF
THE REMAINING entrance panels (i.e., all entrance panels other
than the one from which the call was made).
NOTE: If a second-generation entrance panel is installed in a fi rst-
generation system, it must be programmed for TYPE 1.
GENERAL LAYOUT DIAGRAMS
Before installing the system, it is necessary to determine which
installation diagram is applicable. As an aid in selecting the correct
diagram, a number of general layouts summarizing the possible
confi gurations are provided on the following pages.
Once the desired system confi guration has been identifi ed, fi nd the
number of the diagram to be used for the doorphone or video
doorphone system in question in the table.
Any diagrams which are not enclosed with this publication are available
from our after-sales service.
IMPORTANT:
In systems with or without a guard door switchboard stations and
featuring multiple riser cables for apartment station connection, the
main entrance can be equipped only with a digital entrance module.
Conventional entrance panels adapted by installing a digitizer cannot
be used.
In systems with or without a guard door switchboard stations and
featuring a single riser cable for apartment station connection,
conventional entrance panels adapted by installing a digitizer can be
used only if there are no more than two outdoor stations with automatic
switching between them. If there are three or more such outdoor
stations, use only digital entrance modules.
To facilitate installation work, however, it is recommended that digital
entrance modules be used in all cases, employing conventional
entrance panels with digitizers only where strictly necessary.
