The RIF-1032 is an external GPI interface designed for the Artist digital intercom. The device connects to the expansion ports of all Artist 1000, 2000 and 3000 series control panels, as well as the DIF-1000, via CAT5 cabling. While six RIF-1032 GPI interfaces can be cascaded for each matrix port, this versatile interface provides 32 single-fused, potential free change-over contacts as well as potential free inputs.
