5-Call Addon Master Station

The AP1057 5-Call Master System is a flexible and expandable intercom system that supports up to six stations, which can be configured as a mix of master and sub-stations. For setups using only substations that communicate with a single master, a simple two-pair wiring configuration is sufficient. However, if all stations need to function as masters and communicate with each other, a 12-conductor cable is required. To minimize interference and ensure clear communication, shielded wiring is recommended. This AP1076 is used in multi-master systems.

The system is powered by a 12V DC power supply (included in the 5-call kit) is capable of driving the entire network.
