Product Overview

The Siemens - Fire Safety Manual Fire-Alarm Box (Model MSI-B6F), which operates

with the FireFinder XLS and MXL fire-alarm control panels (FACPs), provides the

most advanced method of address programming and supervision currently available

to the fire industry.

Model MSI-B6F is the essence of an ‘intelligent initiating device’ through the built-in,

microcomputer-chip technology of each box; as well as Model MSI-B6F’s

sophisticated, bi-directional communication capabilities with the FireFinder XLS and

the MXL FACPs. The manual fire-alarm box’s microcomputer chip has the capacity of

storing - in memory - identification and operating-status data.

Specifications

Model MSI-B6F has all-metal-material construction, which is matte finished in red

with raised white lettering. The housing accommodates a ‘pull-down’ a lever which -

when operated - locks in position, indicating the manual fire-alarm box has been

activated.

The pull-down lever remains down and locked, until each intelligent manual fire-

alarm box is reset, via first opening the hinged housing cover with an Allen Key,

followed by closing and locking the cover.

Siemens - Fire Safety’s innovative technology also allows all Model MSI-series

Intelligent Manual Fire-Alarm Boxes to be programmed via the Model DPU

Programmer / Tester. The Model DPU Programmer / Tester is a compact, portable

and menu-driven accessory that makes programming and testing a manual fire-

alarm box more efficient, reliable and quicker than previous methods.

Model DPU eliminates the need for the device’s mechanical addressing mechanisms

(such as: program jumpers, dip switches or rotary dials) because Model DPU

electronically sets the pull station’s microcomputer chip’s non-volatile memory.

Specifications (cont.) Mounting Diagram Vibration, corrosion and other conditions, which can deteriorate mechanical-addressing mechanisms, are no longer a cause for concern because each Model MSI-B6F box is fitted with screw terminals for connection to an addressable circuit. Model MSI-B6F can be either surface or semi-flush mounted. Model MS-FB Backbox Overall, the Model MSI-series manual fire-alarm boxes derive their power, communicate information and receive commands over a single pair of wires.
