The Delsar LifeDetector LD3, available from OTB Products , is a seismic/acoustic listening device that is designed specifically to detect and locate trapped live victims in collapsed structures caused by earthquakes, explosions, landslides, mine disasters or construction cave-ins.
Rescue teams around the world have relied upon the LifeDetector for over 15 years to rapidly detect and locate victims of collapsed buildings. The LifeDetector essentially converts the entire collapsed structure into a large sensitive microphone to pinpoint signals from the entombed victims.
The seismic and acoustic sensors of the LifeDetector convert vibrations created by the live victim into audible and visual signals. The new Delsar LifeDetector model LD3 is smaller, lighter and sensitive, with new features designed to make victim detection and location easier and accurate. The LifeDetector is built for reliability and has the ability to withstand days of continuous use at the disaster site.
Following are the features of the Delsar LifeDetector LD3:
- Improved cable design speeds setup; connectors do not have to be aligned for connection and colour coding makes locating proper connector simple.
- Dual inputs for increased sensor deployment flexibility; allows two acoustic search probes to be used simultaneously for stereo comparison.
- Audio loop record function records last five minutes of audio for playback and comparison.
- Filters can be selected to reduce interfering noises.
- Stereo function allows any two channels to be selected for stereo comparison in headphones.
- Display panel shows relative signal strength of all six sensors simultaneously to allow positive identification of the strongest signal; peaking meter on each bar indicates highest amplitude reached by each sensor.
- Uses the new Lithium Ion rechargeable battery tube pack as well as disposable cells and the Searchcam belt pack battery system, making the Delsar LifeDetector power compatible.
- Improved headphone design with integrated boom microphone for two-way communication through acoustic probes; also provides intercom feature between two operators.
- Improved seismic sensor design to increase stability and addition of a connector guard to protect sensor connectors from impact damage.
- Acoustic sensor attaches to sensor cable or can be attached to the optional telescoping probe to enable penetration into layers of debris.
