3. Inspection, points to verify
Your safety is related to the integrity of your equipment.
Petzl recommends a detailed inspection by a competent person at least once every 12
months (depending on current regulations in your country, and your conditions of usage).
Warning: your intensity of use may cause you to inspect your PPE more frequently. Follow the
procedures described at Petzl.com. Record the results on your PPE inspection form: type,
model, manufacturer contact info, serial number or individual number, dates: manufacture,
purchase, first use, next periodic inspection; problems, comments, inspector's name and
signature.
Before each use
Verify the absence of any cracks, deformation, marks, wear, corrosion on the product (side
plates, axles, rivets, cam, brake plates, attachment hole, anti-error catch). Check the condition
of the safety gate and verify that it works properly (return spring, complete closure). Check the
condition of the handle and verify that it works properly (cam drive, return spring, anti-panic
function). Check the cam's mobility.
During use
It is important to regularly monitor the condition of the product and its connections to the other
equipment in the system. Make sure that all items of equipment are correctly positioned with
respect to each other.
Beware of rubbing or contact with any external object that could interfere with device function
(free rotation of the device, of the cam, of the handle...).
Warning: locking effectiveness can vary depending on the condition of the rope (wear, dirt,
moisture, rain, ice...).
Braking effectiveness varies depending on the condition of the rope and the conditions of
usage (diameter, moisture, rain, ice, dirt...). For every rope, before use, you must familiarize
yourself with the braking effectiveness.
4. Compatibility
Verify that this product is compatible with the other elements of the system in your application
(compatible = good functional interaction).
Equipment used with your I'D S must meet current standards in your country (e.g. EN 1497
or EN 813 harnesses).
The safety gate allows the moving side plate to be opened and the rope to be installed without
removing the connector. The I'D S can therefore be used with the CAPTIV positioning bar to
optimize connector positioning.
5. Function principle and test
The I'D S locks the rope in one direction and allows the rope to slide in the other direction.
The rope friction in the cam groove causes the cam to rotate, which locks the rope by pinching
it against the brake plate.
Locking can be gradually released by operating the handle (always hold the brake-side rope).
Warning: any excessive pulling on the handle can cause a loss of control.
AUTO-LOCK system
The AUTO-LOCK system locks the load automatically and returns the handle to the stop
position.
Anti-panic function
The anti-panic function automatically stops the descent if the user pulls the handle too far. To
resume the descent, allow the handle to return to the stop position before operating it again.
6. Installing the I'D S
Install a locking carabiner on the I'D S for attachment to the harness or anchor.
6a. Connection to a harness
Open the moving side plate and raise the handle slightly to allow the cam to move. Install the
rope around the cam in the direction indicated by the icons marked on the device. Close the
moving side plate, making sure that the gate closes completely. Each time the rope is installed,
check that the rope locks in the desired direction. The anti-error catch helps detect a backward
installation of the rope.
6b. Connection to an anchor
Open the moving side plate and raise the handle slightly to allow the cam to move. Install the
rope around the cam in the direction indicated by the icons marked on the device. Close the
moving side plate, making sure that the gate closes completely. Each time the rope is installed,
check that the rope locks in the desired direction. Pass the rope through a directional carabiner
on the anchor or through the auxiliary brake (sold separately). Warning: the anti-error catch will
not work unless the rope passes through a directional carabiner on the anchor.
6c. Locking the safety gate
If it is necessary to prevent the device from opening once the rope is installed (e.g. rescue kit),
the safety gate can be locked with the supplied screw.
7. Rope access
EN 12841: 2006 type C
Descender for progression on rope.
Maximum working load: 150 kg for a single person; usage up to 200 kg is possible for two
people in a rope rescue situation with 10.5 to 11.5 mm ropes only.
Ropes tested during the CE EN 12841 type C certification:
- Petzl CLUB 10 mm.
- Teufelberger KMIII 11.5 mm.
To reduce the risk of a fall or pendulum, keep the rope between the I'D S and the anchor as
tight and as vertical as possible.
Devices of type B and C are designed for progression on rope; they must be used together
with a type A belay system (e.g. ASAP). When the full weight of the user is on the safety rope, it
becomes a work rope and so must be used with another safety rope.
TECHNICAL NOTICE I'D S
8. Rescue descender
EN 341: 2011 class A
- Maximum energy of descent 7.5 MJ.
Energy = user weight x gravity x length of descent x number of descents.
- Ropes tested, maximum working load, maximum descent: see drawings.
- Minimum load: 30 kg.
- To reduce the risk of a fall, do not allow slack in the rope between the I'D S and the user.
- Protect the I'D S from environmental conditions if it is left installed on the anchor between
inspections.
- EN 341 testing temperature: -40° C in dry conditions, -4° C in wet and cold conditions.
- Install the I'D S on the anchor in a way that does not interfere with the descent.
- Control the speed of descent; a loss of control can be difficult to correct.
- The I'D S can overheat and damage the rope in a descent that is too long or too fast.
- In the context of the EN 341 standard, the I'D S is designed only for rescue use.
- Specifications of ropes tested:
Nylon and polyester ropes.
1. Sheath slippage (%)
2. Elongation (%)
3. Mass of the sheath (%)
4. Mass of the core material (%)
5. Mass per unit length (g/m)
6. Shrinkage (%)
ANSI / ASSE Z359.4 - 2013
Maximum descent height: 200 m.
The I'D S can be used for multiple successive descents by ensuring that the device does not
overheat.
Refer to ANSI Z359.1 and ANSI Z359.4 standards and any applicable regulations.
Energy = user weight x gravity x length of descent x number of descents.
Anchors used for work or rescue must have a strength of 3100 pounds (13.8 kN) or at least 5
times the load applied to the system. If the anchor is used for fall arrest, it must have a higher
strength and meet the requirements of the ANSI Z359.1 standard.
Connections to anchors must be done in a way that does not reduce the anchor strength, and
that avoids any accidental movement of the system during use. Perform a tension test on the
connection before applying the full load.
9. Usage on a harness
9a. Descending
Gradually pull the handle to allow the rope to slide, always holding the brake-side rope.
9b. Extra friction
Add friction in case of difficulty controlling speed, if the rope is new or slippery, or for any use
with a heavy load or with two people.
To add friction, pass the rope through an extra carabiner connected to the I'D S's carabiner, or
through the auxiliary brake (sold separately).
WARNING: when using the open auxiliary brake, direct the rope so that it always stays in
place inside the brake. Beware of twists or loops of rope that could cause the rope to come
out of the brake.
9c. Stop position
Before letting go of the rope, make sure the handle has properly returned to the stop position.
Beware of any rubbing, against the structure or equipment, that could prevent the return of
the handle. If the handle is not in the stop position, it is exposed to accidental snagging that
can cause unlocking.
9d. Occasional ascent
The I'D S can be moved up the rope at any time, without manipulating the handle.
10. Belay device/descender
EN 15151-1: 2012 type 8
Belay device with variable friction function for belaying in climbing and similar activities.
Use only ropes in the diameter range indicated as compatible. Specified rope diameters have
a tolerance of up to 0.2 mm. The diameter of a rope and its characteristics can vary depending
on usage.
Certification tests are carried out with an 80 kg mass.
10a. Always hold the brake-side rope when the climber is moving
10b. Giving slack
While holding the brake-side rope, press the cam with your thumb to allow the rope to slide.
Pull the rope with the other hand.
10c. Lowering
Gradually pull the handle to allow the rope to slide, always holding the brake-side rope.
11. Usage on an anchor
The brake-side rope must pass through a directional carabiner on the anchor or through the
auxiliary brake (sold separately).
WARNING: when using the open auxiliary brake, direct the rope so that it always stays in
place inside the brake. Beware of twists or loops of rope that could cause the rope to come
out of the brake.
11a. Lowering
Gradually pull the handle to allow the rope to slide, always holding the brake-side rope.
11b. Giving slack
While holding the brake-side rope, press the cam with your thumb to allow the rope to slide.
Pull the rope with the other hand.
11c. Stop position
Before letting go of the rope, make sure the handle has properly returned to the stop position.
Beware of any rubbing, against the structure or equipment, that could prevent the return of
the handle. If the handle is not in the stop position, it is exposed to accidental snagging that
can cause unlocking.
12. Limitations on use
These Instructions for Use specify essential parameters to follow when using the descender:
mass, height, speed, compatible ropes...
Other factors can come into play, such as the condition of the rope (new ropes are often
slippery), or the temperature of use (high heat reduces braking effectiveness).
The descender functions optimally under average use conditions. It reaches
its performance limits when all of these parameters approach the maximum.
Under these extreme use conditions, there is a risk of losing control of the
descent and/or damaging the rope.
You must be more alert and not hesitate to take special precautions (add friction, reduce
speed, split the descent into shorter sections using intermediate anchors...).
Limitations on use in the cold:
-40° C under normal conditions.
-4° C under exceptional cold and wet conditions (rain, water spray, condensation...). These
conditions can degrade the functioning of your rope/descender assembly.
13. Additional information
- The I'D S is not suitable for use in a fall arrest system.
- Any dynamic overload can damage the rope.
- You must have a rescue plan and the means to rapidly implement it in case of difficulties
