The SPCG310.000 E-BUS Gateway provides an interface between SPC X-BUS and Sintony E-BUS. The gateway enables the SPC controller to recognize Sintony peripheral devices by simulating the E-BUS devices so they appear to the SPC controller as X-BUS devices. The SPC controller supports up to five acre Intrusion E-Bus Gateways on its X-BUS. The maximum number of Sintony input zones supported by SPC is 252 and the maximum number of Sintony outputs is 174. The SPCG310.000 is supplied without housing. There are a number of housing options available. The acre Intrusion E-Bus Gateway can be mounted within the SPC controller housing, Sintony power supply units or in Sintony transponder housing.
