The Delsar® LifeDetector® systems are used by FEMA, USAR, SUSAR and rescue teams from around the world, the Delsar®
LifeDetector® is a seismic/ acoustic listening device used to detect and locate live victims trapped in:
• Structural Collapse
• Earthquake
• Landslides
• Mine Disasters
• Explosions
• Cave-ins

The Delsar® LifeDetector® Model LD3 provides seismic and acoustic sensors designed to detect and locate signs of a victim’ s
presence in the voids of a collapsed building or similar entrapment situation.
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.
