Description
The F900-MB-6CO Analog Addressable CO Sounder
Base is a combination carbon monoxide (CO) detec-
tor and sounder base. It is designed to be used as a
stand alone device or with the addition of Firecom F900
or F1000 Series analog addressable smoke, heat or
mult-sensor detectors. The CO Sounder Base is also
designedtoallowthedetectorto fitoneway only,without
snagging, with a simple clock wise twist motion. For
stand alone CO detection, two blank covers are avail-
able, the F900-MB-6COBC-LP for the low profile and
the F900-MB-6COBC-HP for the high profile.
The CO Sounder base sounds a temporal 3 sound for
smoke detection and a temporal 4 sound for carbon
monoxide detection. The integral sounder is capable
of producing an 85db tone at 10 feet. The CO Sounder
Base is powered by a UL listed Notification Appliance
Circuit,and maybesynchronized withotherCO Sounder
Bases using appropriate synchronization modules.
Each base has locking feature whereby a socket screw
oneachdetectormaybeturnedtolocateinafixing hole
in the base to prevent unauthorized removal.
The6-inch diameter F900-MB-6COAnalogAddressable
CO Sounder Base mounts to 4-inch octagonal and
4-inchsquare boxes. Whenmountingon aceiling,install
atleast4-inches from the wall. Whenmountingdetector
on the wall, install 4 to 12 inches from the ceiling.

Wiring Connection
FIRECOMINC.COM
The smoke detection is addressed via the XPERT
card. The XPERT card is a plastic, coded card con-
taining seven ‘pips’.
The address is set by simply remov-
ing the ‘pips’ with a screwdriver
according to the ADDRESS DATA
chart shown on the right. The coded
card is then inserted into the side of
the base where it locks into position.
When the detector head is rotated
intothebase,theremaining‘pips’on
thecardoperate the address buttons
on the base of the detector and the
addressis read by the detector elec-
tronics. Factory set Addressable XPERT
cards are available.
The CO detection has its own address setting, which
is unique from the address of the attached smoke
detector. Set the address for the CO detection to the
CO ADDRESS DATA chart.
Address Setting
The power for the smoke detector that is mounted onto
the base and the integral Carbon Monoxide detector are
supplied by the addressable loop.
Powering the Smoke and
CO Detectors
ANotificationCircuitthat reverses voltage polarity powers
thesounder that is included intheCO Sounder Base. The
NAC circuit must be on an approved Firecom Fire Alarm
Panel. The circuit may be wired as Style 4 or Style 6.
RemotebaseoutputsfromtheCOSensorortheinstalled
Smoke Detector determine the type of sound generated
by the sounder. If the CO Sensor detects CO Levels
that indicate an Alarm condition, the sounder base will
generate a Temporal 4 sound (4 rapid beeps separated
by about 5 seconds of silence). If the attached Smoke
Detector indicates an alarm condition, the sounder base
will generate a Temporal 3 sound (three beeps separated
by about 1.5 seconds of silence).
