The Z-6a small contol units can be networked using the RS 485 MASTER-SLAVE-INTERFACES. As a result, up to 12 speaker lines (2 x Z-6a) can be set up on 2-CHANNEL (program 1, Z-6a-1 and program 2, Z-6a-2) with 500 watts / 100 V power. The speaker lines are managed by the DPM-12 desktop microphone station, MSP-MS MASTER-CARD (intercom input module), MSP-SL SLAVE-CARD (intercom input module) and the input INTERFACE (12-zone switch + ALARM button).

Installed as standard are DIN alarms, 2-4 tone gong (REMOTE output) and 1-tone pre-gong (settings are made on the desktop microphone station with DIP switches).

Despite its complex features, the small digital control center Z-6a is easy to use by everyone thanks to saved presettings and further setting options. This is an important product property, especially in areas with changing staff (such as in gastronomy or retail).

Numerous setting options and retrofitting options make the small control unit Z-6a a problem solver in many applications. Optional supplements such as the telephone module TPC-6 (telephone paging card) with direct telephone extension input or the intercom input module MSP-6 (RS 485) with 2 x RJ-45 for connecting up to 15 x microprocessor-controlled DPM-6 or DPM-12 desktop microphone stations are available.
