These instructions are written in accordance with the installation
guidelines of NFPA 72, National Fire Alarm Code. The model
FDOOT441detector(showninFigure1)meetstheVEWFD(Very
Early Warning Fire Detector) classification and sensitivity
requirements of NFPA 76 (Standard for the Fire Protection of
Telecommunications Facilities) incorporating a programmable
“Alert” (Pre-Alarm) sensitivity threshold of 0.2%/ft obscuration
and an “Alarm” sensitivity threshold of 1.0%/ft obscuration.
CAUTION
Detection Device Storage
DO NOT install this detection device until all construction
is completed.
DO NOT store this detection device where it can be
contaminated by dirt, dust, or humidity.
DETECTOR PLACEMENT
Although no specific spacings are set for the detectors used for
a clean air application, for multi-criteria fire detection use 30
foot center spacing (900 sq ft) from NFPAStandard 72 initiating
devices chapter, if practical, as a guide or starting point for a
detector installation layout. This spacing, however, is based on
ideal conditions–smooth ceiling, no air movement, and no
physical obstructions. In some applications, therefore,
considerably less area is protected adequately by each smoke
detector. This is why it is mandatory to closely follow the
installation drawings. In all installations place the detector on
the ceiling, a minimum of 6 inches from a side wall, or on a wall,
12 inches from the ceiling.

If you have any questions regarding detector placement, follow
the drawings provided or approved by Siemens Industry, Inc.,
or by its authorized distributors. This is extremely important! The
detectorplacementsshown onthese drawings werechosen after
a careful evaluation of the area that is protected. Such factors
as air currents, temperature, humidity, pressure, and the nature
of the fire load were carefully considered. Especially noted were
the room or area configuration and the type of ceiling (sloped or
flat, smooth or beamed). Siemens Industry, Inc.’s extensive
experiencein the design ofthe system assures thebestdetector
placement by following these drawings.
TO AVOID NUISANCE ALARMS
Do not locate the detectors where excessive smoke
concentrations exist under normal conditions, or in areas of
prolonged high relative humidity where condensation occurs.
Do not locate the detectors next to an oil burner, kitchen, or
garagewhere exhaust fumes cantriggeran alarm. Other causes
of false alarm are dust accumulation, heavy concentrations of
steam, heavy pipe or cigar smoke, and certain aerosol sprays.
AIR CURRENTS
Before a detector can sense a fire, the products of combustion
or smoke must travel from the fire to the detector. This travel is
especially influenced by air currents; therefore, consider air
movement when designing the system. While combustion
products tend to rise, drafts from hallways, air diffusers, fans,
etc., may help or hinder the travel of combustion products to the
detector. When positioning a detector at a particular location,
give consideration to windows and doors, both open and closed,
to ventilating systems, both in and out of operation, and to other
factors influencing air movement. Do not install a detector in the
air stream of a room air supply diffuser. It is better to position a
detector closer to an air return.
The distance that products of combustion or smoke travel from
a fire to the detector is not usually the shortest linear route.
Combustion products or smoke usually rise to the ceiling, then
spread out. Average ceiling heights of 8 to 10 feet do not
abnormally affect detector response. High ceilings, located in
churches, warehouses, auditoriums, etc., do affect detector
response and should be considered.

SPECIAL CEILING CONSTRUCTION FACTORS
Ceiling obstructions change the natural movement of air and
combustion products. Depending on the direction of smoke
travel, joists and beams can slow the movement of heated air
and smoke, while pockets between them can contain a reduced
level of smoke. Take obstructions created by girders, joists,
beams, air conditioning ducts, or architectural design into
consideration when determining area protection. Refer to the
Initiating Devices chapter of NFPAStandard 72 for Location and
Spacing requirements for specific types of construction; e.g.
beam, suspended, level, sloped and peaked ceilings.
TEMPERATURE – HUMIDITY – PRESSURE –AIR VELOCITY
Thetemperature range for the FDOOT441detector is32°F (0°C)
to 120°F (49°C). Use the detector in environments where the
humidity does not exceed 95% (non-condensing). Normal
changes of atmospheric pressure do not affect detector
sensitivity. The air velocity range is 0-4000 ft/min for open areas
applications. Follow detector spacing and location requirements
in NFPA 72 Chapter for High Air Movement Areas and Control
of Smoke Spread. The detectors can also be installed in duct
applications between 0 and 4000 ft/min. For duct installations
follow detector installation requirements in NFPA 90A, Chapter
for Special Ceiling Construction Factors. When the detectors
employ a fixed temperature rating of 1650F or less, they are
intended for a maximum installation temperature of 1000F
(37.80C).

(see www.STI-USA.com for details).
LED INDICATOR OPERATION
The Model FDOOT441 contains an LED indicator capable of
flashing either one of three distinct colors: green, yellow, or red.
During each flash interval, the microprocessor-based detector
monitors the following:
• Smoke in its sensing chamber
• Smoke sensitivity is within the range indicated on the
nameplate label
• Internal sensors and electronics
Basedon the results of themonitoring, theLED indicator flashes

DETECTOR PROGRAMMING
Each detector must be programmed to respond to a unique
system address between 001 - 050 for FC2005.
• To program the detector address, use the Model DPU
Device Programming Unit. Refer to the DPU Manual, P/N
315-033260.
• Record the loop and device number (system address) for
the detector on the detector label and on the base to
prevent installing the detector in the wrong base. The
optional DPU label printer can be used for this purpose.
Each detector provides pre-programmed parameter sets which
can be selected by the panel. The FDOOT441 provides two
different alarm channels: multi-criteria (UL268) and direct in-
duct (UL268A), and heat (UL521) which can be used
simultaneously and can be configured and switched on or off
individually by the panel.Follow the description and instructions
provided in the operation manual of specific control panel used.
The FDOOT441 can be set to the FDOOT441 Selectable
Application Profiles, the FDOOT441 Selectable Fixed
Temperature Threshold Profiles and the FDOOT441 Selectable
Alarm Threshold Setting Profiles shown in the tables below and
to the right.
Additionally the detector can have another channel that can be
configured by the panel to have a low or high temperature
warning in the range from -4° to 120°F (-20° to 49°C). (Not with
FC2005.)

SMOKEDETECTOR FUNCTIONALTEST (SMOKE TEST GAS)
The fire control panel must be programmed to test mode prior
toperforming a functional (*Go-No-Go)smoke entry test. Failure
to do so may result in a test failure. Refer to the specific control
panel installation operations manual for proper “test mode”
programming instructions. To determine how to put the control
panel in “test mode”, specific programming instructions are
located in the following documents: XLS IOM, P/N 315-033744,
FC2005 Installation Instructions, P/N A6V10333722, and
FC2025/FC2050 Installation Instructions, P/N A6V10315023.
Perform a functional (Go, No-Go) test by activating the detector
using Test Gas, P/N 500-649750, following the instruction on
the gas canister label. This test is simply used to ensure that
smoke can enter the sensing chamber and alarm the control
panel when the detector reaches the programmed obscuration
(concentration) level.
The FDOOT441 detectors can also be tested individually using
the DPU. Refer to the DPU manual, P/N 315-033260.
MAINTENANCE
The control unit automatically indicates the trouble message for
the FDOOT441 detector whose smoke chamber changes to the
level where the set sensitivity cannot be maintained. In such
circumstances, the detector may require replacement.
CAUTION: UNDERNO CIRCUMSTANCES IS THE DETECTORHEAD
TO BE DISASSEMBLED. NO REPAIRS SHOULD BE ATTEMPTED.
DO NOT PAINT
The detector/base plastic is marked DO NOT PAINT. This is
intended to prohibit painting during routine maintenance of the
occupancy which can affect proper operation of the detector.
