Gas Point XCD-RTD Oxygen, Toxic & Combustible Remote
Gas Sensors
Class 1 Div 2 Transmitter O2, Cl2, CO, H2, H2S, NH3, NO, NO2, SO2
remote gas sensor

In this image the basic XCD-RTD is the yellow housing (1) at the top. The sensor is the black component (2) at the bottom. The circular component (3) is the remote mounting hardware. The sensor can be screwed into either the basic housing (non remote configuration) or into the remote housing (remote configuration as shown here)
The conduit (4) in between is for the electrical connection and is not included with the product

Sensepoint XCD RTD from Honeywell makes it easy on your maintenance team, time and budget when faced with the challenge of monitoring toxic gases in Class I, Div. 2 areas. You can mount the unit up to 100 feet from the transmitter to obtain maximum gas detection coverage in areas not easily accessible or where the sensor would not be visible, as in high-or low-level concealed areas, or detection outside the room being monitored. XCD RTD offers unrivaled flexibility and performance via its easily recognizable display (traffic light pattern) to convey safety status, communication and mounting options, and built in diagnostics
Ealarm status indicatorasy Status indication - 3 color backlit display
A tri-color 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 condition.
Easy Configuration
The scale, range, relay operation, alarm set point and electronic tag number of the detector can be adjusted using the transmitter's LCD and non-intrusive magnetic switches. Outputs are automatically inhibited during adjustment,
thereby reducing the risk of false alarm at the control panel during maintenance.
Easy Installation
Sensepoint XCD has an integral mounting plate for surface mounting or can be mounted to a horizontal or vertical pipe using the optional pipe mounting bracket. Electrical installation can be made using either conduit or cable with suitable mechanical protection. Two ¾”NPT entries are provided. A weatherproof cap is also included for use in the harshest outdoor conditions. Other optional accessories include a sunshade/deluge protection, duct mounting kit and collecting cone
Easy maintenance
Sensepoint XCD ensures easy installation and the fastest routine operation by removing the need for hot work permits in hazardous areas. Using easy to replace plug-in sensors, downtime is also reduced and on-going costs are minimized through the use of poison resistant flammable sensors, poison immune infrared Hydrocarbon sensors and patented Surecell™ toxic sensors and Reflex® sensor health check.
