Model 826 DIGITAL CALL SYSTEM
PERFORMANCE CHARACTERISTICS
The URMET DOMUS Model 826 Digital Call System connects entrance
panels to apartment stations in large and medium size residential
complexes.
The system can manage two different sets of codes: one for identifying
doorphone and/or video doorphone apartment stations, and one for
identifying special services. For both sets, codes from 1 to 9999 can
be assigned.
Compared to conventional systems, the Digital Call System provides
the following major advantages:
•
Riser cable connections are made using only 5 wires for standard
doorphone systems, or 7 wires plus coaxial cable for video
doorphone systems. This streamlines installation and makes for
signifi cant savings in materials.
•
Complex multi-entrance systems can be set up for automatic
switching between entrance panels without the need for additional
switching relays.
•
Calls to apartment stations are made by entering a code from 1 to
9999 using the numeric keypad, thus ensuring complete privacy for
residents. However, if residents wish their names to be indicated
on the entrance panel, directory nameplates and/or an electronic
directory with LCD display are available.
•
The system can be readily adapted to use conventional Model 725
or Kombi series entrance panels instead of the standard Digital Call
entrance module, simply by installing the appropriate digitizer.
•
Special codes can be entered on the entrance module keypad to
activate one or more special services, such as opening the entrance
door, actuating one or more electric locks, opening electric gates,
turning on stair lights, arming a security system, and so forth. Each
special code consists of a maximum of four digits from 1 to 9999,
and must always be preceded by a “0”. This “0” has two functions:
it distinguishes special codes from ordinary apartment station call
codes, and prevents the code from being shown on the display while
it is being entered, thus guaranteeing complete security.
•
The system features inherent conversation privacy: only the apartment
station that has received a call from the entrance panel can
communicate with the visitor or hear the call. The conversation can
be maintained for up to 10 minutes, or until another call is made.
The system is designed so that electric locks can be activated
from apartment stations at any time by pressing the switch hook
on conventional buzzer doorphones, or by means of the special
door lock release key provided on electronic call tone signaling
doorphones. Alternatively, the system can be programmed so that
only the apartment station which has received a call can activate the
electric lock and thus open the door.
