DEUS 7300 controlled descent devices are ideal for
applications where longer descents and heavy use
are necessary. Heavy use includes regular, repetitive
use, day after day, OR frequent continuous use
over shorter periods of time such as during mass
evacuation scenarios.
Following is a more detailed description of the
various features and characteristics of use of DEUS
7300 devices.
No User Adjustments. The simplicity of the DEUS
7300 is that there are no user adjustments – no
knobs, handles, levers, switches or cams. The device
is designed this way to minimize opportunities for
"operator error" and to simplify training.
Automatic or Manual Control. Descent with
the DEUS 7300 can be controlled automatically or
manually.
• Automatic mode is always enabled and descent
speed is always limited.
• Descent speed can be manually controlled to any
speed slower than the automatic-mode limit of
the device simply by pulling on the unloaded side
of the rope running through the device. This can
be done either by the person descending or by
an operator.

If descent is being controlled manually and the
person controlling the descent lets go of the free end
of the rope, automatic control is engaged instantly
and descent will proceed at a controlled rate.
It is possible to switch from automatic to manual
control during descent. To do this, either the person
descending or an operator must grab and pull
on the free end of the rope running through the
DEUS 7300 device. Stopping descent cannot be
done in automatic mode. However, this is easily
accomplished in manual mode by pulling on the free
end of the rope.
Descent Speed. The DEUS 7300 features a preset,
automatic descent speed. Devices can also be factory
tuned to provide different descent speeds to match
situational requirements. The default maximum
descent speed is 2 meters per second. However,
maximum speed can be factory tuned to a maximum
descent speed of less than 2 meters per second. Such
adjustments may only be made by a DEUS-Certified
Maintenance Technician.
Maximum descent speed is based on a load of
310 lbs (140 kg). Descent speed will vary as a
function of load, which means that smaller, lighter-
weight people will go slower. The minimum normal
operating load is 65 lbs (30 kg). However, if low loads
are routinely expected, the 7300 can be factory
tuned for lower loads.
Maximum Descent Height. The DEUS 7300 is rated
for use over a maximum vertical distance of 590 ft
(180 m).
Reversible. The DEUS 7300 is reversible without
re-rigging or adjusting the device in any way. Rope
can be pulled through the device in either direction
and a person can descend connected to either end
of the rope.
