The dual power monitoring module BSS-311 provides redundant power input to the BSS-310A module mounted in the fire alarm control panel (BS-420) or the controller (BC-420). AutroSafe 4.

The BSS-311 module may also be used as a standalone unit with two redundant power inputs and one power output.

Connecting several BSS-311 modules in parallel increases output power. In such a configuration, the power inputs must be connected in parallel, e.g., common +24V Input-1 and common 0V Input-1 for all BSS-311 modules.
