Introduction
Cerberus Pyrotronics MSI-10B and 20B intelligent manual
fire alarm boxes provide the markets’ most advanced
method of address programming and supervision, com-
bined with sophisticated control panel communication.
Each MSI manual fire alarm box incorporates a new
custom microcomputer chip. The microcomputer chip
technology, and its sophisticated bi-directional communi-
cation capabilities with the control panel, achieves the
state of an “Intelligent Initiating Device.”
Description
The MSI-10B and 20B are constructed of durable molded
polycarbonate material which is matte finished in red with
raised white lettering. The housing accommodates a “pull-
down” 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 the
manual fire alarm box is reset. The manual fire alarm box is
reset only by opening the hinged housing cover with an
allen key and then closing and locking the cover.
The MSI-10B and 20B manual fire alarm boxes operate
with the MXL, IXL/ICON-1 and XL3 control panels.
The manual fire alarm box’s microcomputer chip has the
capacity of storing, in memory, identification information as
well as important operating status information.
Cerberus Pyrotronics’ innovative technology also allows all
MSI Series Intelligent manual fire alarm boxes to be
programmed by using the Model FPI-32 Programmer/
Tester. The FPI-32 Programmer/Tester is a compact,
portable, menu driven accessory which makes program-
ming and testing a manual fire alarm box device faster,
easier and more dependable than previous methods. The
FPI-32 eliminates the need for the device’s mechanical
addressing mechanisms, such as program jumpers,
dipswitches or rotary dials because the FPI-32 electroni-
cally sets the manual fire alarm box’s address into its
microcomputer chip, nonvolatile memory. Vibration,
corrosion and other conditions which deteriorate mechani-
cal addressing mechanisms are no longer a cause for
concern.
