The Siemens MSI-10B is a single-action addressable manual fire alarm pull station. Specifically, it carries Siemens part number 500-893080. In addition, it activates with one downward pull of the lever for fast alarm initiation.
First, the station’s molded polycarbonate housing is matte red with raised white lettering. As a result, it stays readable in low light and resists most impact damage.
How the Siemens MSI-10B Works
First, a user pulls the lever down to activate the alarm. Then, the lever locks in the down position. Therefore, anyone walking by can see the station has been operated.
Furthermore, the station resets only by opening the hinged cover with an Allen key, then closing and locking the cover again. As a result, casual or accidental resets are not possible.
In addition, the MSI-10B communicates on the Siemens addressable SLC. Therefore, the panel identifies the exact station that was pulled, not just the zone.
Compatible Siemens Panels
The MSI-10B was specified for several Siemens addressable platforms. Specifically, it operates with:
- Siemens MXL
- Siemens IXL / ICON-1
- Siemens XL3
However, before ordering, confirm your panel model and firmware revision. Also, newer Siemens platforms may require a different MSI variant.

When Single-Action Stations Are Used
Specifically, single-action pull stations meet most US fire alarm code requirements for manual signaling. However, some authorities having jurisdiction (AHJs) require dual-action stations in certain occupancies. Therefore, always verify your local code before swapping a dual-action station for a single-action MSI-10B.
