Notifier Sensepoint XCD - Manual (Page 3)

There are three different types of the XCD
transmitter for use with three different families
of sensors.
The mV type transmitter is for use with the
mV family of XCD sensors including catalytic
sensors to detect flammable gases in the
range 0-100%LEL and infrared (IR) sensors
for detection of Hydrocarbon gases in the
range 0-100%LEL and 0-100%Vol*, as well as
Carbon Dioxide (CO
2
) in the range 0-2%Vol.
The EC type transmitter is for use with
the EC family of XCD sensors including
Carbon Monoxide (CO), Hydrogen Sulfide,
(H
2
S) and Hydrogen (H
2
).
The Oxygen transmitter is for use with the
Oxygen (O
2
) XCD sensors.
A transmitter can auto-recognise any sensor
from within its sensor family. The sensor
simply plugs into the bottom of the transmitter
and the transmitter automatically configures
itself accordingly.
Ready, Steady, Go!
Sensepoint XCD uses three instantly
recognisable ‘traffic light’ colours to indicate
its status. The large tri-colour backlit LCD
is steady green to indicate normal operation,
flashes yellow to indicate a fault/warning
and flashes red to indicate an alarm. This
allows anyone in the area to clearly see at a
glance the status of any detector. This can be
particularly useful to identify detector status if
the detector is located in a difficult to access
area or if a number of detectors are located in
the same area.
