2.4 Description of the wireless seismic sensor
The
LEADER Search
has the wireless seismic sensors which are used to locate a buried victim.
These
exceptionally sensitive
sensors are capable of detecting the slightest sounds made by victims.
The different search methods are not explained in this manual. Refer to the operational search
instructions used in your field interventions.
In an open area these wireless sensors have a maximum range of 100 m.
In operation, depending on the configuration of the zone, these wireless sensors can be used up to about
30 m.
A wireless sensor has:
•
A
/ a removable base to access the battery compartment
(3 AAA batteries).
•
B
/ an aerial.
•
C
/ an
ON/OFF
button with LED.
•
D
/ a strap to handle the sensor in the ruins or rubble.
•
E
/ a number corresponding to its pairing number.
Magnetic plates (magnets)
Each wireless sensor is shipped with a magnetic
plate that can be screwed directly onto its lower
part. This plate can be used on the metal beams
of collapsed buildings which are well known
to conduct vibrations optimally.
Metal probes
Each sensor is also shipped with a probe
that can be screwed directly onto its lower part.
These probes are used on loose soil to increase
vibration reception.
A wire sensor has:
•
A
/ wire sensor.
•
B
/ cable reel with 8m.
•
C
/ connector to box or 2
nd
sensor.
•
D
/ connector for 2
nd
sensor.
•
E
/ sensor corresponding number.
The first sensor is wired to connect on the box, the second is to connect the first sensor.
