GB2 2-Wire Audio Intercom System
Ideal for Single-Unit or Multi-Unit Buildings, up to 256 Audio Stations (Open-Voice or Handset Type). Optional Access Control and Touchscreen Monitors!
The GB2™ Series, simply put, is our lowest cost multi-family digital audio-intercom system. The GB2™ series connects to two (2) non-polarized wires and can handle up to 256 apartment audio stations and up to four (4) door entry stations.
While the GB2™ Series digital audio-intercom is designed primarily for use in multi-family (apartment house) or commercial office buildings, it can also be used in residential applications, in "villa mode".
Options include multiple entrance capability, video monitors, secondary (single or multiple) camera switching and multi-relay outputs.
The GB2™ Series door stations are available in the NEXA Aluminum (flush or surface), INOX Stainless Steel (flush or surface) or JAZZ (surface/economy/2-Button maximum).
The GB2™ system uses simple 2-conductor non-polarized wiring making it ideal for new installations as well as for retrofit applications. All audio, video and data functions are fully digital and using the RAP-2150 cable you can run up to 300 meters from the entrance panel to the furthest audio station.
For CAT5 Cabling, the 4 solid color wires must be joined together as one, and the 4 striped wires must also be joined together as one to create your 2-wire cabling structure.
