u Modern, ultra-low profile design
u Color inserts match the surrounding decor
The FCP‑500 Conventional Flush-mount Detectors are
UL Listed, open area photoelectric smoke detectors.
Use them with commercial fire protective signaling
systems and household fire warning systems (see
NFPA 72, the National Fire Alarm Code).
These smoke detectors are available as a photoelectric
smoke detector or as a multi‑sensor detector with an
additional carbon monoxide (CO) sensor. The
detectors are ideal for areas where increased levels of
dust and fibers are expected. Each type is offered in
white or transparent with color inserts.
These smoke detectors satisfy the most demanding
aesthetic requirements. Their ultra-low profile design
offers flush ceiling mounting. The detectors and covers
in the P versions are supplied with reversible printed
color rings in 32 colors for individual color matching.
Functions
Sensor Technology and Signal Processing
All of these detectors are equipped with two optical
sensors and a contamination sensor. The FCP‑500‑C
multi-sensor detector also has a CO sensor.
u Smooth, easily-cleaned detector surface
u Innovative retention mechanism
u High reliability
All sensor signals are constantly analyzed by the
internal signal electronics through specially developed
algorithms.
Multiple criteria optical sensors with the CO sensor
results in an extremely high tolerance to unwanted
alarms. Consequently, the detector can be used in
areas with small amounts of non-fire-related smoke,
steam, or dust.
Optical (Smoke) Sensor (all models)
The optical sensor operates according to the scattered
light method.
The LEDs transmit pulsed infrared light at a defined
angle into the scattered light area. If a fire occurs, the
light is scattered by the smoke particles and strikes
the photo diodes that transform the quantity of light
into a proportional electrical signal.
Interference effects from daylight and lighting sources
are filtered out with an optical daylight filter and by
using electronic filtering and rectification algorithms.
The detector's various diodes (infrared and photo) are
individually controlled by the detector's electronics.
Independent signal combinations are produced that
are ideal for detecting smoke. This makes it possible

to differentiate between smoke and interference
agents (insects, objects). In addition, the detector's
algorithm checks the plausibility of the timing and
correlation of sensor signals. This makes it possible to
detect errors in the signal electronics or the LEDs.
CO sensor (C models only)
Notice
The CO sensor is for detection enhancement only.
It is not a CO detector and cannot activate an
alarm in the presence of CO only.
Without the presence of CO, the smoke sensor is half
as sensitive to smoke as a standard commercial
photoelectric smoke detector. This reduces false
alarms. When the sensor detects CO, the detection
chamber's sensitivity to smoke increases so it is equal
to that of a standard commercial photoelectric smoke
chamber.
Contamination Sensor (all models)
The degree of contamination on the detector surface
or a blockage of the detector is continually measured
by the contamination (antimask) sensor. Heavy
contamination of the detector surface or a blockage
causes a fault indication.
Additional Performance Features
• A clearly visible two-color LED indicates various
operating states:
– A green LED flashes every 8 seconds when the
detector has power and the smoke sampling
circuitry is working.
– A green double flash every 8 seconds indicates a
trouble.
– A green flash every second indicates that the
detector is in test mode. This test mode, that
checks the physical function of the optical and
CO sensors, starts by activating the detector's
dry reed contact with a magnet for at least 2 sec
but not more than 4 sec.
• Perform an electrical function test by activating the
dry reed contact for more than 10 sec. The detector
activates an alarm and the LED turns red.
• An external alarm LED indicator can be connected.
• The innovative detector lock operates on a click and
lock principle to provide fast and simple insertion and
replacement of the detector. Use the specially
developed FAA‑500‑RTL Removal Tool, especially for
high mounting heights.
• Convenient detector testing is available with the
FAA‑500‑TTL Test Adapter with Magnet.

Installation/configuration notes
• For detailed instructions, see the FCP-500 Series
Installation Guide.
• Compatible with all UL Listed four-wire control
panels. Refer to the manufacturer's installation
instructions for proper EOL resistor selection. The
EOL resistor can be connected to terminals in the
FCA-500-E base.
• Install the detectors exclusively in the FCA‑500 or
FCA‑500‑E bases provided. In addition, install the
detector base in an FAA‑500‑BB‑UL ceiling-mount
back box.
• Do not use these detectors outdoors.
• Maintain an unobstructed hemispherical space with a
radius of 1.7 ft (50 cm) below the detector.
• Ensure that people, larger animals, plants, or other
objects do not intrude into this hemispherical area
and that no parts of the detector surface become
covered.
• Install the detector in a position which is out of arm's
reach. A minimum mounting height of 9 ft (2.7 m) is
recommended.
• Do not install thes detectors in rooms where data is
transmitted by means of high-intensity infrared light
(such as rooms with IR systems for interpreters).
• Do not mount the detectors in direct sunlight.
• Maintain a minimum distance of 1.7 ft (50 cm) from
lamps. Do not mount the detectors in a cone of light
from lamps.
• Consult NFPA 72 for proper detector placement. Use
the specifications of a standard spot smoke detector.
A half-inch conduit connector can be mounted to the
back box.
• Six‑conductor wiring is required to connect power,
alarm contacts, and trouble contacts.
