5.2
System with entrance hierarchy
In case of the system with entrance hierarchy two types of entrances can be
distinguished: main (master) entrances and slave (subordinate) entrances. CD-3100
can operate from one up to four main entrances and up to 64 staircases (buildings)
with slave entrances. From one up to three slave entrances can lead to each
staircase (see Fig. 3). In practice the maximum number of subordinate entrances
(served by the electronic cassette EC-3100/U) depends on system connections -
wires length, theirs profile and configuration. L+/L- line resistance between the
furthest electronic‘s cassettes shouldn‘t exceed 10
W

Figure 3: Multi-entrance system
main entrances, connection can be established with each apartment in any building
or staircase.
By means of panels situated at slave entrances, connection can be established only
with the apartments located in the staircase or the building, to which a given
entrance is leading.
At the same moment, when one panel is used, on displays of the other panels the
message [ZAJ] will appear informing that temporarily they cannot be used.
If during conversation led from the slave entrance in one of the buildings (staircases)
an attempt to establish connection from the main entrance with any apartment in
such a building (staircase) will be carried out, then such earlier conversation will
be interrupted and an attempt to establish connection from the main entrance will
follow.
An electro-catch shall always be released at this entrance, from which the call has
been made. Combination lock and electronic key can be used both at the main
entrance and at the slave entrance.
Doorphone has been provided with the function of ”quick entrance”, facilitating
usage of doorphone systems with the main entrance (see page 42). In the Fig. 5,
a scheme illustrating certain sections of doorphone wiring system and the required
number of cables are presented.
