The LifeDetector Model 80M287612 is designed to detectlocate signs of a
victim’s presence in the voids of a collapsed building or similar entrapment situation using seismic and/or acoustic sensors. The 80M287612 is equipped with two separate sensor systems to detectlocate
victims. The seismic sensor detects sound vibrations generated by a victim’s
movement or activity traveling through the structural members of the building. The
acoustic sensor detects sound vibrations traveling through the surrounding airspace.
The 80M287612 Display Interface (DI) allows an operator to listen toreview
the relative response of up to two seismic sensors or two acoustic sensors. The
80M287612 displays each sensor’s response on the display graph simultaneously for
easy comparisonto provide continuous feedback of the victim’s response. The
acoustic sensors allow two-way communication with the victim using an integrated intercom system.
The 80M287612 comes standard for use with disposable Lithium Ion batteries only.
However, Rechargeable Lithium Ion batteries as well as a chargerpower supply
are available as an option.
Case Layout
The case is designed to house all of the 80M287612 standard equipment. The following
drawing shows 80M287612 component location within the case.
Optional Items
escoping Probe (for use with acoustic sensors) - This rigid probe allows the
operator to attach an acoustic sensor to its end providing the ability to push the
sensor into a crevasse or hole with a diameter as small as two inches (5 cm).
The escoping probe allows the operator to place the sensor into the lower
layers of a collapsed structure by extending the probe as needed.
Rigid Threaded Tube (for use with acoustic sensors) - The rigid threaded tubes
come in fixed length sections. An acoustic sensor attaches to one end. A single
tube can be used or additional tubes that extend the reach of the acoustic probe
can be added.
Replacement Sensors - The 80M287612 supports up to two seismic sensors or
two acoustic sensors.
Replacement 3 or 10 Meter Cables
All other components such as spikes, magnetic clamps,batteries are also available.
80M287612 Display Interface
The Display Interface (DI) is the main control center for the 80M287612. The DI controls
each sensordisplays the sensor’s responses on the bar graph while routing the
signals to the headphones for listening.
The numbered sensor selection keys control which sensors are listened to in the
headphones. Each numbered key corresponds to a numbered sensor. The LED in the upper-left corner of the key indicates that the sensor channel audio is selected for listening.
Sensor Selection Keys 12 are also used when the acoustic sensors are connected. If
an acoustic sensor is connected, the LED in the lower-right corner of the key is illuminated.
The Amplitude Graph LED bars indicate the response level of each sensorcorrespond to the Sensor Channel Keys located above each bar.
The L-R headphone key activates the stereo feature allowing the operator to listen to one sensor in one earanother sensor in the other.
The lowhigh filter keys control the signal filters. These filters can be used to reduce the effects of certain types of noises that can interfere with listening to the seismic sensors.
The LOW key activates a low-frequency cut filter that reduces signal frequencies that are below 200 Hz. The HIGH key activates a high-frequency filter that reduces signal frequencies that are above 1000 Hz. This filter reduces background noise like “hiss”.
The Zoom key changes the resolution of the bar graph to better differentiate the signals in high signal level conditions. These conditions usually occur when the sensors are close to each other during the victim location mode.
Zoom mode makes comparison between sensors easier.
