Siemens BC-35 Battery Charger and Transfer Switch for System 3
The Siemens BC-35 is the battery charger and transfer switch module for the Siemens System 3 fire alarm control panel platform. The BC-35 performs two critical functions: it maintains the standby battery at full charge under normal AC power conditions, and it automatically transfers the panel to battery backup power in the event of an AC power failure.
As a core component of the System 3 power subsystem, the BC-35 works in conjunction with the PS-35 power supply to deliver continuous, reliable power to the fire alarm system. Proper operation of the BC-35 is essential for code compliance, as NFPA 72 requires fire alarm systems to maintain secondary (battery) power for a specified duration.
The BC-35 is a genuine Siemens component designed specifically for the System 3 platform. Using OEM-quality battery charger and transfer switch components is critical in life-safety systems where battery backup integrity directly impacts emergency response capability.
Life Safety Consultants supports legacy Siemens System 3 installations with genuine components including the BC-35.
