The LD3 is equipped with two separate sensor systems to detect and locate victims. The seismic sensor system detects sound vibrations traveling through the structure, generated by trapped victims - such as tapping or knocking. The acoustic sensor detects sound vibrations traveling through the surrounding airspace - such as shouting. The LD3 Display Interface (DI) allows an operator to listen to and review the relative response of up to six seismic sensors or two acoustic sensors (acoustic sensor #2 is optional). The LD3 displays each sensor’s response on the display graph simultaneously for easy comparison and to provide continuous feedback of the victim’s response. The operator of the system can listen to any combination of the six seismic sensors.The acoustic sensors allow two-way communication with the victim using an integrated intercom system.

The DVS-100 (Delsar Victim Simulator) is an excellent training tool for victim search and rescue, but also doubles as a valubale calibration unit for the Delsar’s Seisimc Sensors for use on different surface materials. Sensor Connecting Cable - 9’ (3m) Sensor Connecting Cable 30 feet (10m) on Spool Seismic Sensor x6 Acoustic Sensor #1 Magnetic Sensor Clamp x2 DVS-100 Antenna & Remote Victim Simulator (DVS-100) Headset with Boom Mic x2 Lithium Ion Battery Stick Charger Delsar Console Disposable Battery Adapter Tube Rechargeable Lithium Ion Batteries x2 Sensor Spikes Battery Charger Power Supply Lanyard Used by FEMA, UKSAR, USAR, SUSAR and rescue teams from around the world, the Delsar USAR Kit is a seismic/acoustic listening device used to detect and locate live victims trapped in: • Collapsed structures caused by earthquakes • Explosions • Landslides • Mine disasters or cave-ins The Delsar USAR Kit converts the entire collapsed structure into a large sensitive microphone that transmits noises from entombed victims. The seismic and acoustic sensors convert vibrations created by the live victim into audible and visual signals. The Delsar is rugged, reliable and able to withstand days of continuous use at the disaster site. www.con-space.com The Delsar Victim Simulator (DVS) The DVS is a very overlooked accessory to the Delsar Life Detector Family of products. Not only does it provide an excellent tool for training on victim search it also can be used to help calibrate the seismic sensors for different surfaces. For training purposes the simulator can be hidden in a fake ruble pile or parking garage providing a constant tapping noise for trainees to locate. The remote control give the trainers the flexibility of changing the rhythm to teach patience when conducting searches. Victims get tired and cannot always make a constant, consistent sound. The DVS has another very critical role to play in the proper use of the Delsar Victim Simulator. Each material whether it be grass, carpet, wood, gravel, concrete or steel has different seismic properties which will affect how far the sensors can be placed apart from each other. The soft materials will absorb vibration which can limit the distances between sensors well below the supplied 10 meter cables. A simple test using the DVS will help the search team determine the safe, allowable distance between sensors by using its constant, consistent vibration signature. Place the DVS on the material you wish to use the seismic sensors on; then move a seismic sensor way from the DVS until it can no longer be heard through the headset. Bring the sensor back to the last point it was heard and measure that distance from the DVS and times it by 2. That will give you the maximum distance between sensors. If you move to a new material, calibrate again. Why Upgrade From the Old LDC Delsar Model? Migration From the LDC to the LD3 LDC operators may be presented with a scenario where they have to use the newer LD3 system. Migrating from one system to the other is relatively simple. The general principles are the same. This section highlights special considerations that an operator must know when using each system. It is not designed as an Operator’s Guide. For more detail on each system, refer to the appropriate section in this guide. LDC Display vs. the LD3 Display The major difference between the LDC and LD3 display interface is the LD3’s inclusion of display panels showing relative signal strength of all 6 sensors simultaneously, allowing positive identification of the strongest signal. The LDC only uses 2 display panels for all 6 sensors, which requires the user to manually navigate through in order to identify the strongest signal.

Seismic and Acoustic Sensors NEW LDC Seismic Sensor LD3 Acoustic Sensor OLD LD3 Seismic Sensor LDC Intercom Probe Considerations Batteries The LD3 uses a single Lithium Ion battery pack that is also used for the SearchCam® Products. Sensor Response Graphs The LD3 model displays responses from all six sensors simultaneously for instant visual comparison. The LDC model can display responses from only two sensors at a time. The operator selects which sensors will be viewed for comparison on channels A and B. Connections There are two sensor ports on the LD3. A T-Cable junction is not required to run two separate strings of sensors. There are two headphone ports on the LD3. A headphone splitter is not required. Seismic sensor connector polarity is not an issue with the LD3. Sensor Operation Sensors are detected automatically by the DI console of the LD3 models. All sensors will provide at least a low level reading on the sensor bar graphs. The LD3 displays the readings of all six sensors simultaneously. The operator of the LDC model must choose two sensors at the same time to be viewed and compared. Sensors The new sensors are shorter and fatter, making them more stable and less likely to tip over then the old sensors. Intercom Probe/Acoustic Sensors Acoustic sensors are used to detect airborne sounds and communicate with a victim in both models. In the LD3, acoustic sensors connect directly to the Display Interface console in the same way as the seismic sensors. Up to two acoustic sensors can be used. In the LD3, acoustic sensors cannot be mixed with seismic sensors in the same string. Acoustic sensors are assigned to sensor keys 1 and 2 on the LD3 model. Microphone The mic on the LDC model is located on the face of the control console. The boom microphone on the LD3 is part of the headphone assembly. The boom mics are muted on the LD3. To allow the two operators to communicate with each other and provide voice-over narration during recording. The microphones on the LD3 can be muted to isolate sensor responses as the only sounds heard. Press the PTT and L-R keys simultaneously to unmute the microphones. Cables The LD3’s cables are the at both ends, eliminating the male and female connections of the old LDC. www.con-space.com LDC/LD3 Functional Difference - Quick Reference LDC Key LD3 Key Differences x6 The LDC sensor key selects which sensor will be viewed on the channel A and B bar graphs. Since all six sensors are displayed on the LD3 bar graphs, the sensor selection keys are used to select which of the sensors will be heard in the headphones. The LDC headphone key is used to select which channel will be heard; A, B, or one in each ear for stereo mode. The LD3 headphone key is used only to select two sensors for stereo listening. The gain keys function as amplification keys for headphone level in both models and for the zoom level in the LD3. The Low filter key on the LD3 covers the filter range of both the Rumble and PWR filters of the LDC. The High filter is equivalent to the Hiss filter. Equivalent keys used for “Push to Talk”. Key must be released to hear a victim response. LD3 Mini starts with microphone muted by default. Press PTT once to activate the Microphone. Press L-R + PTT simultaneously to Mute the Microphone again. Note: the mute state is indicated by PTT light blinking slowly. Equivalent keys for On/Off. N/A Activates the Record feature only available on the LD3. Press this key to begin recording the audio being sent to the headphones. N/A Activates the Playback feature. Press this key to listen to recorded sensor responses. Use in conjunction with the 3,4, 5, and 6 keys to control how the recording is played back. HIGH Indicates gain level in both models. Also indicates battery level and zoom level in the LD3. LOW N/A Changes the resolution of the bar graph to better differentiate the signals in high level conditions. Only available in the LD3. ALERT Low battery level is indicated by the Alert LED on the LDC and by the LO BATT LED on the LD3. The LD3 has automatic low battery shutdown. The LED will flash 10 minutes prior to shutdown. Pushing this button on the LD3 will display the residual battery level on the green bar graph.

V6V 2V4 SS Weight Acoustic Sensor Sensor Cable 30.2 feet (10 m) Weight Loaded Research has shown that airborne sound travels within the under layers of debris, but does not often escape through the outer layers of debris to the surface. It is therefore necessary to penetrate into the structure to effectively use the acoustic sensor. The acoustic sensor was designed with this in mind and can be placed under the surface layers of building debris.
