The Intelligent CO Detector and Sounder Base (45681-
800ADV) is an analog/addressable combination carbon
monoxide (CO) detector for use with Advanced fi re alarm
control panels. In addition to carbon monoxide monitoring,
the CO detector and sounder base can accommodate any
Advanced intelligent smoke, heat, or multi-sensor detector.
For stand-alone CO detection, blank covers are available in
low profi le (45681-292) and high profi le (45681-380) formats.
The built in sounder of the Intelligent CO Detector and
Sounder Base base, can provide either a temporal 3 (fi re
alarm event) or temporal 4 (CO event) signal, with the fi re
alarm event having the highest priority. The sounder base
requires a separate regulated 24 VDC supply whether from
an AxisAX Notifi cation Appliance Circuit (NAC) or from a
Listed, supervised, power supply. In addition, common area
sounder synchronization is possible with the MB-SDRT-SM,
Synchronization Module.
The CO sensor is an electrochemical sensor that is able
to detect three levels of carbon monoxide and has a life of
approximately six years, in normal environmental conditions.
The CO sensor is fully supervised and provides a signal for
fi eld replacement once it has reached its end of life cycle.
The Intelligent CO Detector is individually addressed utilizing
segments 1-7 of an integral DIP switch. In addition, the
optional intelligent smoke, heat, or multi-sensor detector
is individually addressed through the base, by a patented
address (“XPerT”) card. The address is quickly and easily set
by removing “pips” on the XPerT card according to a chart
supplied with each base.
In addition to an automatic daily test of the Intelligent CO
Detector by the fi re alarm control panel, the CO Detector can
be manually tested locally, via an on-board test button, by
spraying CO test gas through its outer edge opening, or by
manually initiating a test command from the fi re alarm control
panel.
The Intelligent CO Detector and Sounder Base is designed
as a 6” diameter base which can mounted to a standard 4”
octagonal or 4” square electrical box.
