properly and is ready to use. If the Cam doesn’t lock the device,
check whether the rope has been correctly inserted, if the de-
vice still doesn’t lock on to the rope, remove it from further use
immediately. Use on an anchor point (Fig. 8.2): 1) Remember
to pull the free end of the rope through the snapping catch. 2)
Pulling on the engaged side of the rope, the cam must lock on
to the rope. If the Cam doesn’t lock the device, check whether
the rope has been correctly inserted, if the device still doesn’t
lock on to the rope, remove it from further use immediately.
EBS (Extraordinay breaking system).
EBS is security systems that decreases the speed rather than in-
crease it, when the lever is accidentally pulled downwards.
At-
tention! This maneuver has to be used only in case of emer-
gency and not during normal employment. Regular use of this
safety system may lead to a faster wear of the rope. To resume
the descent, firmly hold the free end of the rope and grad-
ually release the control handle back in to the “REST” posi-
tion. At this stage you can re-start descending following the
instruction above.
EN 12841:2006. The Sparrow 200R descender is a Person-
al Protective Equipment (PPE) intended to be incorporated in a
rope access system. Rope length adjusters must not be used for
fall arrest. Max work load 210 kg. The Sparrow 200R descend-
er is a rope length adjuster type C intended for descending a
rope (anchor line). An anchor line loaded with the entire weight
of the user, has to be considered a work line and is not meant
to arrest a fall. It is mandatory to use a fall arrest back-up de-
vice type A connected to a safety line. Pay attention that the
back-up system is never loaded on to the work line.
Abseil of one person (Fig. 9). Holding the free end of the
rope, gradually pull on the control handle to adjust the speed.
For difficult abseils, requiring a stronger brake power, insert
the free end of the rope through the snapping catch in order
to have a better control over the heavy weight and gradually
pull on the control handle to adjust the speed.
Attention! Al-
ways hold the free end of the rope whilst abseiling. To stop the
descent, let the control handle go: The lever will spontaneous-
ly return to “REST” mode. No further maneuvers are required
to up-keep the position hands free. For avoiding any interfer-
ing with the handle or to work more comfortably, it’s possible
to shift the control handle on to “STAND BY” mode.
Atten-
tion! Never lose governance over your abseil, it may result dif-
ficult to regain control.
Warnings.
Always wear a pair of good suitable gloves to protect your
hands when manoeuvring the device and the rope; Use only
static or semi-static rope (core + sheath) Ø 11 mm certified to
EN 1891 type A (For the certification of this device, the follow-
ing rope has been employed: Bornack TEC Static Pro 11 mm);
There are restrictions for the length or slant of sloped pathways.
No special precautions are required when accessing sloped
trails; Any overloading or loading on the device can harm the
anchor line; Never use lanyards or extensions of any mean to
connect the device to your harness; During use, the anchor
point must always be placed above the waist belt attachment
point of your harness; The technical performances of the an-
chor line might vary considerably, due to dirt, moisture, ice, re-
peated descents on the same stretch: keep in mind that these
variances will influence the behavior of the rope inside the de-
vice, and consequently, the speed of descent.
EN 341:2011
The Sparrow 200R descender can be employed in rescue
operations. Maximum allowed descend: 180 m; work load:
30÷200 kg.
Accompanied descent, device on the harness (Fig. 10).
Insert the free end of the rope through the snapping catch.
Holding the free end of the rope, gradually pull on the con-
trol handle to adjust the descent speed. To stop the descent,
let the control handle go: The lever will spontaneously return to
“REST” mode.
Attention! Always hold the free end of the rope
whilst abseiling. Attention! Never lose governance over your
abseil, it may result difficult to regain control.
Descent from an anchor point (Fig. 11-12).
Insert the free end of the rope through the snapping catch; hold
the free end of the rope gently push up the control lever to re-
lease the rope gradually. To adjust the speed, vary the hold
over the free end of the rope. To stop the descent, let the con-
trol handle go: The lever will spontaneously return to “REST”
mode. No further maneuvers are required to up-keep the po-
sition hands free.
Attention! Always hold thight the free end
of the rope whilst lowering the load. When you are lowering
a light weight (30-50 kg) and you have difficulties feeding the
rope (rope might be dirty, wet of too stiff), you can release the
rope from the snapping catch, advance the hand holding the
free end of the rope to control the speed.
Attention! Pay atten-
tion that the hand holding the free end of the rope doesn’t get
too close to the device.
Attention! Never lose governance over
your abseil, it may result difficult to regain control.
Warnings. Always wear a pair of good suitable gloves to pro-
tect your hands when manoeuvring the device and the rope;
Verify that the connections of the device and the anchor are ar-
ranged correctly, in such a way that the abseil cannot be ham-
pered; Full body harnesses are the only mean for retain the
body that can be used with the device; In the due case it is nec-
essary to leave the device placed in the work location, make
sure to adequately protect it from the atmospheric conditions
and from dirt; The device is meant to bear with a total descent
energy of 7-,5 x 10
6
J. The total descent energy is caluculated E
= m x g x h x n (m = mass; g = gravity acceleration; h = max-
imum lowering height; n = number of descents). This device
has been tested with the following parameters: m max = 200
kg; g = 9.81 m/s
2 ; h max = 180 m; n = 21 descents. Atten-
tion! Consider this as the maximum attainable energy during
use; Whenever you need to do a rapid sequence of lowering’s,
pay particular attention taking back in the rope for storing it in
the bag or the designated area, to avoid forming knots or twists
on the line, which would hamper with the next descents; Pay at-
tention about the possibility of the device to overheat during a
descent and consequently damage the anchor line.
Technical specifications of the rope used for testing.
Sheath slippage: 0 mm; Elongation: < 3,4%; Weight of the
sheath: 31 g/m; Weight of the core: 45 g/m; Weight of the
rope: 76 g/m; Shrinkage: < 1,7%; Tenacity: > 36 kN; Ma-
terial: Polyamide.
6) PERIODIC CHECK.
At least every 12 months (6 months for usage in the sea), a rig-
orous check of the device must be carried out by the manufac-
turer or expert staff expressly certified by the manufacturer. This
frequency can vary depending on the frequency and intensity of
usage. Performing periodic checks on a regular basis is essen-
