The 80M287612 is equipped with two separate sensor systems to detect and locate 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 to and review 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 comparison and to 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 charger and power 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, and batteries are also available. 80M287612 Display Interface The Display Interface （DI） is the main control center for the 80M287612. The DI controls each sensor and displays 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 1 and 2 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 sensor and correspond 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 ear and another sensor in the other. The low and high 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. 產(chǎn)品說明書 | （美國直銷） 迷你型音頻生命探測儀（迷你型生命探測儀）80M287612 |
