Sensepoint XCD RFD
A flammable gas transmitter
for use with remotely mounted
flammable gas sensors
Sensepoint XCD RFD
Applications
•
•
•
•
•
Compatible with high temperature sensors for use in and around Gas Turbine Enclosures
and solvent based printing and coating
drying ovens
Compliant with the requirements of HSE guidance
note PM84
Transmitter can be mounted in easy to access
area even if sensor is in a hard to access or
restricted access area
Sensor can be mounted up to 30 metres
(100 feet) from transmitter
Standard temperature catalytic and infrared
sensor types also available
Reliable detection
•
•
•
Compatible with Honeywell Analytics’ proven
catalytic bead flammable gas sensors
High temperature gas sensors have thermally
matched beads for highest accuracy and stability
enabling low alarm levels
Gas sensors use long life, poison resistant beads
as standard, reducing ongoing cost of ownership
Easy to Use
Sensepoint XCD RFD (Remote Flammable
Detector) has been specifically designed for use
with remotely mounted flammable gas sensors.
This configuration is ideal for applications
where the sensor is required to be mounted
remotely from the transmitter in areas
where temperatures are well above ambient
(up to 150°C/302°F), or that are difficult to
access. The transmitter can be mounted at a
suitable location away from this area where it
is easy to access, view its display and interact
with via the user interface.
• Easy to read tri-colour backlit display with digits,
bar graph and icons
• Fully configurable via non-intrusive magnetic
switches
• Selectable sink or source 4-20mA output
• Auto-inhibit during maintenance prevents
false alarms
Cost Effective

•
Sensepoint XCD common transmitter platform
Reduces training costs
Reduced spares and stock costs
Non-intrusive, one-man operation reduces
cost of maintenance
Optional Sensepoint XCD plug-in sensor
reduces maintenance time further
Sensepoint XCD RFD is suitable for use with
several Honeywell Analytics’ sensors; the
Sensepoint XCD catalytic bead and infrared
type plug-in sensors and the Sensepoint
standard and high temperature sensors.
These sensors can be mounted up to
30 metres (100 feet) away from the transmitter
thereby accommodating even the most remote
and inaccessible applications.
The gas range is user adjustable at the
transmitter from 0-100%LEL down to
0-20%LEL. The 0-20%LEL range is particularly
suited for use with the Sensepoint high
temperature sensors that have thermally
matched beads providing optimum accuracy
and stability allowing alarm set points as low
as 5%LEL.
The transmitter’s tri-colour backlit LCD clearly
indicates the unit’s status at a glance, even
from a distance. A steady green backlight
indicates normal operation, flashing yellow
indicates fault and flashing red indicates
an alarm.
Outputs include 2 programmable alarm relays,
1 programmable fault relay as well as 4-20mA
output (sink or source selectable).
The range, relay operation, alarm set points
and electronic tag number of the detector
can be adjusted using the transmitter’s LCD
and the non-intrusive magnetic switches.
Outputs are automatically inhibited during
adjustment thereby reducing the risk of false
alarm at the control panel during maintenance.
Sensepoint XCD RFD
Overview
The Sensepoint XCD Remote Flammable
Detector (RFD) can be used with Sensepoint
XCD remote flammable sensors (Catalytic and
IR), or with the Sensepoint range of flammable
gas detectors. The sensors can be directly
mounted to the M25 entry at the bottom of the
transmitter, or remotely mounted to suitable
junction boxes or duct mounting assemblies.
Sensepoint flammable detectors are available in
both standard and high temperature versions.

and socket (with weather protection fitted)
Ready, Steady, Go!
Sensepoint XCD RFD uses three instantly
recognisable ‘traffic light’ colours to indicate its
status. The large tri-colour backlit LCD flashes
red to indicate an alarm, flashes yellow to
indicate a fault and is steady green to indicate
normal operation. 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.

Installation Options
The Sensepoint XCD RFD transmitter has an integral mounting plate consisting of four mounting
holes on the transmitter body. The transmitter may be fixed directly to a surface mounting, or to
a horizontal or vertical pipe/structure, 40.0-80.0mm (1.6 to 3.1 inches) in diameter/cross section.
The pipe mounting bracket accessory (optional accessory) may be used for this purpose.

Installation
Electrical
Sensepoint XCD RFD is designed for use in
potentially explosive atmospheres. As such,
installation should follow national guidelines
using suitable mechanically protected cable
and glands (M20 and M25). Use 0.5mm2
to 2.5mm2 cross sectional area cable as
needed to ensure minimum operating
voltage at the detector, depending on
installed cable length.

Wiring Schematics
The Sensepoint XCD RFD transmitter may be wired in either current source or current sink
configuration. These two options are offered to allow greater flexibility in the type of control
system that it can be used with. Source/sink is selectable via the switch located on the back
side of the display module; accessible by removing the display module during installation/
commissioning.

NOTES
Performance data is: 1. Taken at nominal 20°C, 50%RH. 2. Applicable over the range 10 to 90% full scale. 3. Measured on units calibrated at 50% full scale. 4. Accuracy at 10% of default full scale (typical A1 alarm) of applied gas, or
minimum (whichever is greater). 5. Measured at 500ml/min for IR and 1 Ltr/min for Catalytic bead using the calibration cup. Contact Honeywell Analytics for any additional data or details. For more details on the Sensepoint Standard and
High Temperature sensors refer to Datasheet DS01069.
