The B520 Auxiliary Power Supply Module is a fully supervised, addressable SDI2 bus device that provides an integrated auxiliary power supply solution for Bosch control panels.

The B520 Auxiliary Power Supply Module is an auxiliary power supply expansion device that connects to compatible control panels through the SDI2 bus. This module is supervised and communicates back to the control panel all status changes. Industrial, commercial, and institutional facilities are typical installations for the B520 module. The B520 rotary switches allow for ease of use in device addressing. The SDI2 Out terminals provide auxiliary power for SDI2 expansion devices such as keypads. The AUX PWR terminals provides added auxiliary power capabilities for additional devices such as PIR's.
