Note: Due to extended storage, the original plastic wrapping of these devices deteriorated. As a result, they were re-packaged, but they are 100% new and fully functional.

The Siemens MSI-20B Dual Action Pull Station delivers dependable manual activation for advanced fire alarm systems. Designed for use with Siemens fire control panels, this pull station ensures both intentional activation and system compatibility. It is ideal for facilities that demand high performance and safety compliance.

Key Features

• Dual-Action Mechanism: To initiate an alarm, users must first push in the handle and then pull it down. This two-step process prevents accidental activations, making it suitable for high-traffic areas.

• Strong and Durable Design: Constructed from high-impact polycarbonate, the MSI-20B withstands tough environments. Additionally, its matte red finish and bold white lettering improve visibility in emergencies.

• Electronic Addressing: Instead of using DIP switches, technicians can assign a unique address using Siemens DPU or FPI-32 programming tools. As a result, installation becomes faster and more accurate.

• Active Supervision: The device maintains continuous communication with Siemens control panels. Due to this feature, the system promptly detects any faults or disconnections.

• Secure and Simple Reset: After activation, the lever locks in place. Technicians can easily reset the unit using an Allen key once the situation is clear.

• Flexible Mounting Options: Whether mounting to a surface or semi-flush wall, the MSI-20B adapts to different building requirements.
