CYPRES is the most commonly used major component in the parachuting world. More than 80,000 units are in actual use and save the lives of more than 80 skydivers each year.
CYPRES 2 combines tried and true quality and reliability with new technology, achievements and discoveries made since 1991.
The CYPRES
2 is available in several different models. Each was designed to meet the
needs of specific users (students, expert skydivers and tandem jumpers).
Each model can indicate altitude in either feet or meters.
Converting models
A
conversion between each model is possible.
Expert <-> Student
Expert <-> Tandem
Student <-> Tandem
To prevent
accidentally setting, the procedure will be performed at the manufacturer.
It will be executed by the same people that built the unit, including new
settings, a new color corresponding push button, a new label, and a
complete functional test. All this at no charge.
Use in a 1-pin reserve
container and the use in a 2-pin reserve container
All CYPRES can be
used in both container types.
Through the plug-and-socket cutter
connection a swop from 1-pin cutter to 2-pin cutter or vice versa can be
simply done by pluging-out and pluging-in without opening the unit and
without use of any tools.
CYPRES 1 was produced
from 1991 to spring 2003 and is no longer available.

Expert CYPRES 2
The Expert
CYPRES can be recognized by the red button on the control
unit.
It activates the release unit when it detects a rate of
descent higher than 78 mph (35 m/sec) at an altitude of approx. 750
feet (approx. 225 meters) above ground level (AGL). In the event of
a cutaway below this height CYPRES will operate down to approx. 130
feet AGL, however activation will not occur unless sufficient speed
is obtained. Below approx. 130 feet (approx. 40 meters) AGL opening
is no longer useful. For this reason, CYPRES ceases operation below
approximately 130 feet AGL.

* These temperature limits do not mean the outside

unit. Therefore, these limits won't have any meaning until the
processing unit itself has reached the temperatures in question. In
actual fact, these limits will rarely be reached due to the
mandatory location of the CYPRES in the reserve container, and the
insulating properties of the processing unit pouch and parachute
canopies.

Student CYPRES 2
The
Student CYPRES can be recognized by the yellow button with the
imprint "Student" on the control unit.
It will activate the
release unit when the rate of descent exceeds 29 mph (13 meters per
second). The activation altitude is split. In the case of rate of
descent being equal to that of freefall, the opening altitude is at
approx. 750 feet (the same as with Expert CYPRES). However, should
the rate of descent be lower than that of freefall but still above
the limit of 29 mph (e.g. with partially opened canopy, or after a
cutaway), then Student CYPRES activates the release unit when the
altitude falls below approx. 1000 feet (approx. 300 meters) above
ground level. The student will then have more time to prepare for
landing. Like the Expert CYPRES, the Student CYPRES ceases operation
below approx. 130 feet AGL.
Unlike the Expert and Tandem CYPRES
models, we recommend that the Student CYPRES be switched off in the
aircraft prior to descent if the jump is aborted and the student
will land with the plane, because the vertical speed of a descending
jump plane will exceed the activation speed of Student
CYPRES.
Be
aware that it is possible to exceed a vertical speed of 29 mph (13
meters per second) under a fully inflated canopy!
If a
jump plane is descending with students still on board, switch the
Student CYPRES off before reaching 1500 ft (450 meters) above
ground.
If this is not possible, the descent rate of the plane
must not exceed 1500 ft/min below 1500 feet above ground. Close open
doors.

Tandem CYPRES 2
The
Tandem CYPRES can be recognized by the blue button with the imprint
"Tandem" on the control unit.
It activates the release unit when
it detects a rate of descent higher than 78 mph (35 m/sec) at an
altitude of approx. 1900 (approx. 570 meters) feet AGL.
Like the
Expert CYPRES, the Tandem CYPRES ceases operation below approx. 130

will not occur until sufficient speed is obtained.

Emergency Air Crew / Pilot CYPRES
2
The Emergency
Air Crew / Pilot CYPRES can be recognized by the green button with
the imprint "Pilot" on the control unit.
This CYPRES version is
designed for aircraft pilots and crew members. It will give them the
extra bit of support which may make the difference between life and
death in case of an emergency.
Unlike other 'family members'
this CYPRES unit is used in the OFF condition. It has an arming pin
mounted in the switch on its side. The pin may, depending on the
version, be pulled out manually by an 'arming' handle on the rig, or
it is connected to the aircraft by a lanyard and will be pulled
automatically on leaving the seat/aircraft.
After the pin is
pulled, the unit will go into its fast calculation mode and
determine, among other parameters, the altitude and rate of descent.
When reaching an altitude below 4000 meter (apx. 13000 ft) and a
vertical rate of descent higher than 35 meter per second (78 mph at
sea level) the Emergency Air Crew / Pilot CYPRES will activate the
cutter, thus initiating the reserve opening sequence.
Technical Data
for the Emergency Air Crew / Pilot CYPRES :
Cable length of control
unit according to customers requirements
Activation delay 5-7
seconds
Activation altitude < 13000 feet
Activation speed
> 35 m/s (78 mph) at sea level
