General
World-class fire and carbon monoxide (CO) detection com-
bined in a single addressable device provides a practical solu-
tion for today’s market.
The IntelliQuad PLUS FCO-851(A) Advanced Multi-Criteria
Fire/CO Detector is a plug-in, addressable device that pro-
vides both fire and carbon monoxide (CO) detection. For fire,
the detector combines four separate sensing elements in one
unit (smoke, CO, light/flame, and heat) to sense multiple com-
ponents of a fire. This approach enables enhanced sensitivity
to real fire with heightened immunity to nuisance particulate.
For CO, the detector’s electrochemical sensing cell creates a
separate signal for life safety CO detection.
CO is a colorless, odorless, and deadly gas that is virtually
impossible to detect with the human senses. It is released
whenever carbon-based fuels (from fossil fuels to firewood)
burn without enough oxygen to form CO
2
. Because the poten-
tial exists for dangerous levels of CO to accumulate in almost
any building, legislation mandating the use of CO detection in
commercial spaces continues to increase across the U.S. and
Canada. The FCO-851(A) is listed to the UL 268 standard for
smoke detectors and the UL 2075 standard for system-con-
nected life safety carbon monoxide monitoring.
The FCO-851(A) should be used in conjunction with the
B200S(COA) intelligent sounder base, which can generate
either a Temp 3 pattern for fire or a Temp 4 pattern for CO
alarm indication.
The B200S(COA) recognizes the System Sensor synchroniza-
tion protocol. This enables it to be used as a component of the
general evacuation signal — along with other System Sensor
horns, horn strobes, and chimes — when connected to a
power supply or Fire Alarm Control Panel (FACP) output capa-
ble of generating the System Sensor synchronization pulses.
With each sounder base carrying a unique address, the FACP
can then command an indvidual sounder — or a group of
sounders — to activate. The command set from the panel can
be tailored to the specific event, allowing selection of volume,
tone, and group.
NOTE: The FCO-851(A) is compatible with the NFS-320(C), NFS-
320SYS, NFS2-640, and NFS2-3030 operating with firmware ver-
sion 17.0 (or higher) in FlashScan® mode; CLIP mode not sup-
ported.
Features
• Unique ability to detect all four major elements of a fire.
• Separate CO detection signal.
• Highest nuisance alarm immunity.
• Automatic drift compensation of smoke sensor and CO cell.
• Uses only one address on the SLC.
• RealTest® CO testing capability.
• Separates audible signal for fire or CO alarm when used
with the B200S base (B200SCOA in Canada).
• CO cell end-of-life warning and fault.
• FlashScan operation.
Sensitivity Settings and
Suggested Applications
• Level 1: 1% / ft of smoke. Suggested for very clean envi-
ronments such as laboratories.
• Level 2: 2% / ft of smoke. Suggested for clean environ-
ments such as offices.
• Level 3: 3% / ft of smoke. Suggested for moderately clean
environments such as hotel rooms, dorm rooms.
• Level 4: 3% / ft of smoke with different algorithm process-
ing and weighting of sensor elements. Suggested for hotel
rooms near a shower, boiler rooms.
• Level 5: 4% / ft of smoke. Suggested for equipment rooms,
kitchens, paint shops.
• Level 6: Thermal alarm at 135°F (57°C).
Once the CO cell has reached end-of-life, the CO sensor no
longer provides life safety protection; however, when the fire
detector enters Photo, Thermal, Infrared (PTIR) mode, the fol-
lowing sensitivities apply:
•
Level 1: 1% / ft of smoke. Suggested for very clean envi-
ronments such as laboratories.
• Level 2: 2% / ft of smoke. Suggested for clean environ-
ments such as offices.
• Level 3: 3% / ft of smoke. Suggested for moderately clean
environments such as hotel rooms, dorm rooms.
• Level 6: Thermal alarm at 135°F (57°C).
