Compatibility with older models

Digital doorphone CD-3100 is based on experience gained in the design and manufacture of CD-3000 doorphone, however, introduced changes do not allow for the use of CD-3100 elements as counterparts to parts used in previous models, in particular in CD-3000 doorphone.
CD-3100 doorphone elements (electronic cassette, outdoor panels) cannot be used as counterparts to CD-2502 system but both systems can co work with each other.

Cooperation with CD-2502 doorphone

CD-2502 and CD-3100 doorphones have different uses, but both systems have been designed in such a way as to complement each other. Their unique features and possible cooperation allow for the construction of complex doorphone systems, which components are optimally matched to user requirements and building design.

For instance, in a fenced property with two gates and four staircases, CD-3100 doorphone will be used to operate the gates, because it provides the ability to connect several panels in one electronic cassette, and the allowable distance between the outdoor panel and the electronic cassette are much greater. CD-2500 doorphones will be installed in staircases, because only one entrance carries for each staircase and there is no need for more expensive CD-3100 system.
