The Autronica 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). Connecting several BSS-311 modules in parallel increases output power. In such a configuration it is essential that the power inputs are connected in parallel, e.g. common +24V Input-1 and common 0V Input-1 for all BSS-311 modules.
Features
Provides redundant power input to the BSS-310A module. The BSS-311 module may also be used as a standalone unit with two redundant power inputs and one power output
Both power inputs are monitored and the common fault output will be de-energized in the case of low input voltage or interruption in any power input wire
Easily plugged onto a standard mounting rail
Designed to meet EN 54 requirements and conforms to CE standards.
