The B208 Octo-input Module is an 8 point expansion device that connects to the control panel through the SDI2 bus. This module is fully supervised and communicates back to the control panel all point status changes. The module's expansion points operate the same as the points on the control. Industrial, commercial, and institutional facilities are typical installations for the B208 module. The B208 Octo-input Modules connect to the SDI2 bus on the control panel using Terminals 33 through 36, or using the interconnect cable. You can connect multiple B208 modules to a single control panel.
