Siemens MSI-20B Dual Action Addressable Pull Station
The Siemens MSI-20B is a dual-action (double-action) addressable manual pull station from the Siemens MSI series. Designed to reduce accidental false alarms, the MSI-20B requires two distinct motions to initiate an alarm signal: a first action to prepare the station, and a second pull to activate. This dual-action mechanism provides critical protection against unintentional activations in high-traffic areas.
The MSI-20B connects directly to Siemens addressable signaling line circuits and is compatible with Siemens MXL, MXLV, FireFinder XLS, and Sinteso fire alarm control panels. Its addressable design allows the panel to identify the exact station that was activated, supporting faster emergency response and simplified system troubleshooting.
