Introduction
The Cerberus Pyrotronics MSI-2S two-stage dual address intelligent manual station provides the markets’
most advanced method of address programming and
supervision, combined with sophisticated control panel
communication. Each MSI-2S manual station incorporates a new custom microcomputer chip. The MSI-2S
microcomputer chip technology, and its sophisticated
bi-directional communication capabilities with the control
panel, achieves the state of an “Intelligent Initiating
Device.” Both the pull switch and the second stage key
switch have their own addresses and are fully identifiable. Only one pair of wires is required by this pull
station.
Description
The MSI-2S is 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 station has been activated. The
pull down lever remains down and locked until the
manual station is reset. The manual station is reset only
by opening the hinged housing cover with an Allen Key
and then closing and locking the cover.
The MSI-2S is designed for 2 stage applications. The
pull station is designed such that the activation of the
first stage of alarm is activated by pulling down the lever.
The second stage alarm is activated when the key switch
is turned on. The manual station’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-2S intelligent manual station to be programmed
by using a new accessory, the Model FPI-32 Programmer/Tester. The FPI-32 Programmer/Tester is a compact,
portable, menu driven accessory which makes programming and testing a manual station device faster, easier
and more dependable than previous methods. The FPI32 eliminates the need for the device’s mechanical

addressing mechanisms, such as program jumpers, dip
switches or rotary dials because the FPI-32 electronically
sets the pull station’s microcomputer chip’s non-volatile
memory. Vibration, corrosion and other conditions which
deteriorate mechanical addressing mechanisms are no
longer a cause for concern.
The MSI-2S is fitted with screw terminals for connection
to an addressable circuit. The MSI-2S can be either
surface or semi-flush mounted. The MSI-2S manual
station operates with the MXL, MXLV and the IXL control
panels. The IXL requires the use of the ICON module to
interface to the MSI-2S. The MSI-2S manual station
derives its power and communication over a single pair
of wires.
The MSI-2S intelligent manual station is Underwriters
Laboratories of Canada listed.
Engineer and Architect Specifications
The addressable manual station shall be constructed of
durable molded polycarbonate material which is matte
finished in red with raised white lettering. The housing
shall accommodate a “pull down” lever, which when
operated, locks in position after releasing a spring
loaded switch. To indicate the manual station has been
activated, the pull down lever shall remain down and
locked until the manual station is reset. The manual
station shall be reset only by opening the hinged housing
cover with an Allen key and then closing and locking the
cover.
The addressable manual station’s two addresses shall be
programmed with the use of a portable programming
accessory. The programming accessory shall be a
Cerberus Pyrotronics FPI-32 Programmer/Tester. The
portable programmer shall be menu driven.
Once the desired addresses are entered, the programmer shall set and verify the addresses. The programming
accessory shall also be capable of testing the device’s
functionality. The addressable manual station’s addresses shall be set by electronic means only. No
mechanical means such as programming pins, dip
switches or rotary dials shall be required to set the
device’s address.
