Siemens FP-11 - Manual (Page 2)

non-mechanical thermal sensor, microprocessor based
electronics with a low-profile plastic cover and base.
The FP-11 utilizes state-of-the-art ASIC and surface
mount technology for maximum reliability. Every FP-11
fire detector is shipped with a protective dust cover.
The FP-11 fire detector utilizes an infrared light
emitting diode (IRLED), and light sensing photodiode.
Under normal conditions, light transmitted by the LED
is directed away from the photodiode and scattered
through the smoke chamber in a controlled pattern.
The smoke chamber is designed to manage light
dissipation and extraneous reflections from dust
particles or other non-smoke airborne contaminants in
such a way as to maintain stable, consistent detector
operation. When smoke enters the detector chamber,
light emitted from the IRLED is scattered by the
smoke particles and is received by the photodiode.
The FP-11 also utilizes a modern, accurate, shock-
resistant thermistor to sense temperature changes.
The “on-board” FirePrint technology allows the
detector to gather smoke and thermal data, and to
analyze this information in the detector’s “neural
network”. By comparing data received with the
common characteristics of fires, or fire fingerprints,
the FP-11 can compare these “Fire Prints” to those of
deceptive phenomena that cause other detectors to
alarm. The advanced FirePrint technology allows the
FP-11 to accurately determine a true fire hazard from
a nonthreatening deceptive phenomena WITHOUT
needing to use alarm delaying verification and confir-
mation techniques, which can increase the probability
of losses due to fire.
The FP-11 provides the highest level of detector
intelligence available today with a detector/control
panel link that allows the user to program the detector
for the specific hazard profile Detectors are optimized
by selecting one of the following applications:
• Office/Retail
• Lobby
• Computer Room
• Dormitory
• Healthcare
• Parking Garage
• Utility/Transformer Room
• Hostile Environment
• Precious Storage
• Air Duct
• Warehouse/Light Manufacturing
The software does the rest; no guessing on detector
sensitivities or alarm verification; the control panel
programs the FP-11 detector for the protected area
without hassle and without confirmation delays.
Once optimized for the hazards in the protected area,
the FP-11 provides the best detection you can buy.
Should the operator or installer forget to program the
detector, the FP-11 will revert to a default setting that
allows it to operate as a standard photoelectric or
photothermal detector.
The FP-11’s FirePrint technology monitors input from
both the photo chamber and the thermal sensor,
evaluating this information with sophisticated
mathematical formulas, or algorithms, comparing this
input to characteristics of both threatening fires and
deceptive phenomena that would “fool” any ordinary
detector. This technology was developed over years of
research and reviewing the results of over 20 years of
fire test data in one of the world’s most advanced fire
research centers. The results of this research are the
mathematical models that form the algorithms used in
FirePrint. No other fire detector has this level of
intelligence or this amount of research and develop-
ment supporting it’s design.
The microprocessor’s software can identify and
disregard false input caused by radio frequency (RFI)
and electromagnetic (EMI) interference, and validates
all trouble conditions before annunciating or reporting
to the control panel. The FP-11 detector’s microproces-
sor uses an integral EEPROM to store the detector’s
address and other critical operating parameters which
include the assigned program values for alarm and
trouble thresholds. Communications within the
detector itself and between the FP-11 and the control
panel, or with the FPI-32 field programmer/tester, are
supervised and safeguarded against disruption by
reliable, microprocessor based error checking routines.
Additionally, the microprocessor supervises all
EEPROM memory locations and provides a high
degree of EEPROM failure fault tolerance.
In MXL(V) applications, the FP-11 determines its
operating status to be normal, in alarm, or in trouble
depending on the difference between the alarm
threshold values stored in the detector’s memory and
the detector’s latest analog measurement. The
detector then communicates changes in its status to
the control panel.
In addition, the MXL(V) control panel will sample the
value of the FP-11’s analog signal over a period of time
in order to determine if those values indicate exces-
sive buildup in the photo chamber; if so, the MXL(V)
will indicate that the particular detector requires
maintenance.
The FP-11 is listed as a self-testing device. The FP-11’s
visible light emitting diode (LED) flashes green every
4 seconds to indicate it is communicating with the
control panel and that it has passed its internal self-
test. Should the detector sense a fault or failure within
its systems, the LED will flash amber and the detector
will transmit that information to the control panel.
A quick visual inspection is sufficient to indicate the
condition of the detector at any time. If more detailed
information is required, a printed report can be
provided from the MXL panel indicating the status
and settings assigned to each individual detector.
When the FP-11 moves to the alarm mode, it will flash
amber and transmit that information to the control
panel. When the MXL(V) confirms the detectors
condition, the panel will instruct the FP-11 to flash red
and to continue flashing until the system is reset at
the control panel. At that same time, any user defined
