5.3 SUPER RED HOT (SRH) COLORIZATION

Bullard XT Series Thermal Imagers include Super Red Hot (SRH) colorization, which displays heat levels in yellow, orange, and red hues. This feature identifies specific heat layers, alerting firefighters to areas of intense heat through visual awareness. The SRH feature automatically adds colorization to areas of a scene that include temperatures above 500° F/260° C.

SRH gives a semi-transparent color overlay to high-temperature areas of the scene, helping the visibility of structural detail, flow paths, or other objects. The Heat Color Reference Bar accompanies SRH and is adjacent to the Temperature Bar. The temperature is illustrated by the filled height of the Temperature Bar and by the Numeric Temperature Indicator. The Heat Color Reference Bar is a visual indicator to quickly allow the user to determine the meaning of the color displayed on the screen. The colors follow a gradient and correspond to the values in Table 2.

Table 2 Standard SRH Colorization Temperature

Temperatures measured with thermal imaging can vary based on several factors (see Bullard's Limitations with Temperature Readings - Caution statement below). Use these features with caution and verify indicated heat levels through traditional means whenever possible.

CAUTION: Thermal imagers cannot directly measure the temperature of an object, instead they detect radiated heat. Temperature indications in thermal imagers are affected by distance, material emissivity, and extreme temperatures. Bullard XT Series Thermal imagers are designed for firefighting applications and are primarily imaging devices, designed to provide general information about a scene. Temperature reading should be interpreted as an approximation. Firefighters MUST continue to rely on and use their firefighting training and safety tactics, at all times.

5.4 SENSITIVITY (GAIN) MODES

XT Series Thermal Imagers feature Seamless Gain Transition. With this technology, the imager smoothly and automatically switches between high and low sensitivity (gain) modes based on scene temperatures. When low sensitivity mode is active, it is indicated by a triangle ⚠️ located in the upper left of the viewing area.

5.5 MAXIMUM SCENE TEMPERATURE

The Maximum Scene Temperature (dynamic range) is the temperature above which heat signature differences can no longer be distinguished. For the QXT Pro the Maximum Scene Temperature is approximately 1200° F (650° C). As scene conditions approach the Maximum Scene Temperature, the display may show a large red zone where the temperature is at or above 1200° F (650° C). Also, the Numeric Temperature Indicator may not correctly display a temperature above 1200° F (650° C). Temperatures measured with thermal imaging can vary based on several factors (see Bullard's Limitations with Temperature Readings - Caution statement on p.7). Use these features with caution and verify indicated heat levels through traditional means whenever possible.

6. ON-SCREEN INDICATORS

The display shows various indicators for imager status and readings:

• Low Gain: Indicated by a triangle ⚠️ in the upper left.
• Power Off: Imager is off.

6.1 TEMPERATURE BAR

The Temperature Bar is a bar-graph style temperature gauge on the right of the display. It represents the approximate temperature of the object within the Temperature Measurement Zone. Accuracy depends on distance and emissivity. The imager is factory-calibrated for normal construction materials. Objects with significantly different emissivity (e.g., metals) may show reduced accuracy.

Temperatures measured with thermal imaging can vary based on several factors (see Bullard's Limitations with Temperature Readings - Caution statement on p.7). Use these features with caution and verify indicated heat levels through traditional means whenever possible.

6.2 NUMERIC TEMPERATURE INDICATOR

The Numeric Temperature Indicator, below the Temperature Bar, shows the approximate temperature of an object in the Temperature Measurement Zone. It aids in comparing objects with similar emissivity and identifying intense heat sources. Temperatures measured with thermal imaging can vary based on several factors (see Bullard's Limitations with Temperature Readings - Caution statement on p.7). Use these features with caution and verify indicated heat levels through traditional means whenever possible.

6.3 BATTERY LEVEL INDICATOR

The battery level indicator at the bottom center of the display shows the current battery level. The bar depletes from left to right. Table 3 shows approximate remaining time.

NOTE: Battery performance may vary with age and temperature.

Table 3 Battery Level Indicators

6.4 OVERHEAT INDICATOR

If the imager overheats, an overheat indicator icon will appear. The imager will automatically switch to a limited function mode to protect itself, potentially disabling non-critical functions to reduce heat generation. To restore full functionality, power off the imager and allow it to cool before powering it back on.

WARNING: FAILURE TO FOLLOW THE INSTRUCTIONS FOR THE OVERHEAT INDICATOR COULD RESULT IN DAMAGE TO THE UNIT AND RENDER THE IMAGER UNSAFE FOR USE. FIREFIGHTERS MUST ALWAYS RELY ON THEIR FIREFIGHTING TRAINING AND SAFETY TACTICS. FAILURE TO DO SO COULD CAUSE DEATH OR SERIOUS INJURY.

6.5 SD CARD INDICATORS

The imager stores images and recordings on an internal SD memory card. If the imager cannot access the SD card, a red SD card icon is displayed, and the imager may not connect to a computer for updates or access to recordings. Other functions may still operate. If the SD Card icon appears blue, the file system may be corrupted. Try connecting to a PC via USB, properly disconnecting, and restarting the imager. If the issue persists, contact Bullard Customer Service or your Bullard Distributor.

7. SAFETY KICKOUT

For your safety, the imager will automatically deactivate certain features when more than 5% of the pixels on the screen are above the threshold for colorization (typically 500° F / 260° C). This safety feature applies to Thermal Throttle, On-Screen Playback, and the On-Screen Settings Menu.

If you are in a situation where more than 5% of the pixels on the screen are above the threshold for colorization and you are not in Thermal Throttle or On-Screen Playback, those icons will appear crossed out ❌. This means that you cannot activate the feature at this time (see image to the left).

9. ALTERNATE MODES

9.1 LEGACY THERMAL THROTTLE INTERFACE

Departments with multiple imagers of various Bullard models may want imagers to operate with the same Thermal Throttle interface. The QXT Pro has a new Thermal Throttle interface; however, you may choose the legacy interface as an option. With the legacy interface you will see a TT number instead of the temperature next to the Thermal Throttle icon. To activate the Legacy Thermal Throttle Interface, go to the MyBullard Imager Configurator at https://mybullard.com.

9.2 SUPER RED HOT: EARLY ENGAGE MODE

Super Red Hot colorization, which typically engages at 500° F, can be set to Early Engage Mode, which begins colorization at 150° C / 300° F. Early Engage Mode is sometimes preferred for departments looking to match colorization across multiple brands of imagers.

To change your Super Red Hot colorization to Early Engage Mode, go to the MyBullard Imager Configurator at: https://mybullard.com.

Early Engage Mode will start colorizing in yellow at 150° C / 302° F, orange at 300° C / 572° F, red at 450° C / 842° F, and deep red at 650° C / 1202° F. The Heat Color Reference Bar will change as well to reflect this change.

Due to the colorization starting at 150° C, the safety kickout will occur earlier, when 5% of the pixels on the screen are above 150° C / 302° F.

NOTE: It is recommended to use the same colorization mode on all thermal imagers within the same department. It is the responsibility of the customer to choose the colorization mode and provide proper training.

Temperatures measured with thermal imaging can vary based on several factors (see Bullard's Limitations with Temperature Readings - Caution statement on p.7). Use these features with caution and verify indicated heat levels through traditional means whenever possible.

11. DEPLOYMENT/OPERATIONAL LIFE

11.1 CHARGING YOUR IMAGER

Your Bullard XT battery can be charged with one of two charging systems: the included USB Wall Charger or the optional Wireless Charger. To charge your imager with the Wireless Charger, please refer to the XT Series Wireless Charger User Manual.

To charge with the USB Wall Charger, open the USB cover located on the rubber boot at the bottom of the display side of the imager. Plug the USB power cord into a wall outlet using the included AC adapter. When the connection has been verified and the battery is charging, the Bullard XT power button LED will pulse GREEN. When fully charged, the same LED will change to steady GREEN.

CAUTION: Be careful when inserting the micro-USB into your imager, there is only one way it can be inserted. The Bullard logo should be facing the display when it is properly inserted. See the images below.

Table 4 Power Button Charging Indicators

If you see a flashing orange LED power button indicator, remove the imager from the XT Series Wireless Charger and reseat it on the charger, or disconnect the USB cable and reconnect. If this does not work, refer to the troubleshooting section of the manual.

WARNING: EXPLOSION HAZARD. DO NOT CONNECT OR DISCONNECT THE EQUIPMENT (THERMAL IMAGER) TO ANY CHARGER IN A HAZARDOUS LOCATION. FAILURE TO FOLLOW THIS INSTRUCTION COULD CAUSE DEATH OR SERIOUS INJURY.

CAUTION: THE TEMPERATURE RANGE TO CHARGE THE BATTERY IS 32°F TO +113°F (0°C TO 45°C). IF YOU CHARGE THE BATTERY AT TEMPERATURES OUTSIDE OF THIS RANGE, IT CAN CAUSE SEVERE DAMAGE TO THE BATTERY.

WARNING: ONLY USE CHARGERS APPROVED BY BULLARD TO CHARGE THE BATTERY. USING NON-BULLARD CHARGERS CAN DAMAGE THE BATTERY.

If the Bullard XT internal control software determines that internal temperatures are too high or too low for battery charging, the power button will flash ORANGE/RED until the imager internal temperature stabilizes to a range appropriate for charging. It will continue charging automatically when moderate temperatures have been reached.

NOTES ON CHARGING:

1. Do not use a computer USB connection to charge the thermal imager. Connection to a computer via USB is only intended for the purpose of downloading video and/or communicating with the imager. It is not guaranteed that a computer will supply the necessary power for appropriate charging.
2. Due to the variety of USB standards, Bullard cannot guarantee charging performance with non-Bullard chargers nor non-Bullard USB adapters.
3. Battery charging temperature range is 32° F (0° C) to +113° F (45° C).
4. Internal lithium-ion battery is designed for a long life. Bullard recommends leaving the XT connected to your preferred Bullard charging system so the unit is charged and ready for use. For maximum life of the imager, avoid fully depleting the battery.
5. Power off the imager during charging.

12. CARE AND STORAGE INSTRUCTIONS

Bullard XT requires little maintenance. For best results, after each use:

• Clean and disinfect the outside of the unit with mild soap or detergent.
• Wipe the lens with a soft cloth.
• Clean the display with a soft cloth.
• Check screw tightness on cover window; torque is 5-inch pounds.
• Store your Bullard XT, powered off, on the provided USB charger, optional Wireless Charger, or in the delivery case provided. For best performance, Bullard recommends leaving your imager charging when not in use.

12.1 Stickers and Markings

You may place department and/or company information on your Bullard XT. When adding stickers or other markings, do NOT cover the certification label, thermal imager lens, cover window, or display. Do not place stickers on the bottom of the imager, as it may interfere with the wireless charging and will cover the certification label. Do not engrave in the plastic material as this can damage the unit and jeopardize sealing.

If placing stickers or labels on your imagers here are some things to know:

1. UL approved 2 Mil Polyester 3-1309 or Scotchlite material with High Heat adhesive work well.
2. Avoid metal/metalized stickers/labels.

WARNING: DO NOT USE SOLVENTS OR PAINT THINNERS TO CLEAN THE BULLARD THERMAL IMAGER AS THEY COULD PERMANENTLY MAR THE SURFACE OR DEGRADE THE PROTECTIVE PROPERTIES OF THE CASING. DO NOT INTENTIONALLY SUBMERGE THE UNIT UNDER WATER OR SUBJECT THE UNIT TO HIGH PRESSURE WATER. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD CAUSE DAMAGE AND RENDER THE THERMAL IMAGER UNSAFE FOR USE.
