The EDS-D1 unit is user controlled by a
windowed push button control switch. The switch
has two push buttons, one for advancing through
the modes, the other for reversing through the
modes. A stop is provided inside the selector
switch stopping at the most forward setting
"R/M" and most reversed setting "OFF".
The EDS-D1 has three main modes
of user controlled operation as seen
and described in the text and figures.
They are:
1. Fully-Automatic
2. Semi-Automatic
3. Manual

FEATURES
•
Easy to use two-button control, small size and light weight.
•
Automatically will adjust oxygen flow for different altitudes.
•
Allows operation for different oxygen delivery protocols and variable flow regulators.
•
Multi-mode push-button control switch allows the setting of various automatic altitude trip points,
Night & Day flight operations and over-ride high flow settings for special or emergency purposes.
•
Positive GRN / RED indicators for FLOW / NO-FLOW oxygen delivery status.
•
Provides Apnea alarm to inform user of kinked, pinched, disconnected lines or holding breath too long.
•
Saves existing oxygen supply by as much as 8 times over standard constant-flow delivery protocols.
•
Much less dry-mouth and associated discomfort over standard constant-flow delivery protocols.
•
The EDS pulse-demand technology has been recognized by the FAA as having the equivalent level
of safety per FAR. 23.1447 operating with a cannula or face mask.
The EDS-D1 has proven to be very reliable and has been used by many pilots for several years in various types
of aviation. The EDS-D1 unit and has no means inside itself to provide a by pass of oxygen in the event of a
total failure. If this should become desirable, here are a few oxygen bypassing methods you can implement with
optional equipment
The most common emergency
bypassing method is with the A-4
flowmeter/regulator control unit that
couples the outlets of the EDS unit
and the A-4 unit together into one
standard cannula. This allows the
pilot to simply throw an on/off switch
to bypass the EDS unit, then having
the ability to adjust the flowmeter for the altitude.
Because many pilots fly with passengers only part of the time, the A-3 or A4 flowmeter/regulator and an
Oxymizer® cannula can be setup for the bypass station and for the passenger.
Oxymizer is a trade
mark of Chad
