The Siemens 100-115588 is a 50 microfarad, 50 volt electrolytic capacitor sold in packs of 10. It is a Siemens-supplied service part for board-level repair of Siemens fire alarm control panels and modules.
Electrolytic capacitors are common service items in fire alarm panel maintenance. As a result, panels that have been in service for many years frequently need them replaced. In addition, the 100-115588 part number identifies the exact spec Siemens specifies for the affected boards.
Each package contains 10 individual capacitors. Therefore, a service tech has enough on hand for multiple board repairs without reordering between calls. Furthermore, the pack-of-10 pricing is generally lower per piece than single-quantity orders.
What the Siemens 100-115588 Capacitor Is For
This is a passive component used in board-level service work — not a complete device. Specifically, technicians use it to replace failed or aged 50uF/50V electrolytic capacitors in Siemens fire alarm panel boards. Always verify the value, polarity, and physical footprint match the original component on the board before installation.
