The simplified Citymax PALACE telephones, in addition to the standard functions of electronic intercom, allow internal communication (all with all) within the same office, company or home, between 12 points or extensions. The entrance panel and internal call are different to distinguish its origin. The terminals have 6 buttons under the telephone arm and an additional one on the base to make the call to each extension. The phones are slimline format and are made of high impact ABS plastic with a mirror polished finish for easy cleaning.
