Connect The Breathing Apparatus To The Posi3 Usb; Identify The Major Parts - Honeywell Posi3 USB Setup Manual

The screen will list all of the models in the
selected database that have serial numbers
assigned to them.
Select a row by clicking in it so the whole row
appears highlighted and click the "Choose
Model" button at lower left. The Choose
Model screen will be shown. If the model that
is being exported from Access matches an
existing model in the new PostgreSQL
database, then select it. Otherwise, click the
"New" button and add the model specifications
into the new database.
Continue with this process of selecting the
serial numbers from the access database and
exporting them into the new PostgreSQL
database until all models have been entered.
Once all serial numbers have been
successfully imported into the PostgreSQL
database, click Next.
The software will show the numbers of serial
numbers that were imported, and will show
those that were not imported. Apparatus with
serial numbers already present in the
PostgreSQL database will not be imported.
7. Connect the breathing
apparatus to the
Posi3 USB.
Now that the software is installed and running,
and the Posi3 USB is assembled, it is time to
connect the breathing apparatus to the Posi3
USB. One of the strengths of the Posi3 USB
is its adaptability. For simpler tests, the
breathing apparatus's facepiece serves as the
only interface between the Posi3 USB and the
breathing apparatus. More complex tests
require the use of a series of manifolds to
deliver pressure levels from points in the
breathing apparatus's airstream to the Posi3
USB's internal transducers. Every breathing
apparatus is different, so specific parts and
instructions may be required for your breathing
apparatus to be connected to the Posi3 USB.
The Complete SCBA Test requires the
following connections between the SCBA
and the Posi3 USB:
1. The breathing apparatus facepiece is put
on the Posi3 USB's anatomically correct
test head, just as it would be placed on
the head of a person. See section 7.2
below.
2. The appropriate high or low-pressure
manifold is inserted between the cylinder
and the first stage regulator and then
connected to the high-pressure inlet fitting
located at the lower right side on the front
face of the Posi3 USB. See section 7.3.
3. If possible, the first stage manifold is
connected from a location downstream of
the first stage regulator and upstream of
the facepiece to the medium pressure
inlet, which is located at the lower left side
on the front panel of the Posi3 USB. (See
section 7.4)
7.1

Identify the major parts

First identify the three manifolds that are
included with the Posi3 USB*. Each of the
manifolds comes with a factory label that
identifies it by name and part number.
54-21-A03 Assembly, Manifold, 2250 PSI
The low pressure manifold can be recognized
by its brass T-fitting and black handwheel.
This manifold will be used with all low
pressure SCBA (3000 PSI and below).
54-21-A02 Assembly, Manifold, 4500 PSI
The high pressure manifold can be
recognized by its stainless steel T-fitting and
handwheel. This manifold will be used with all
high pressure SCBA (above 3000 PSI).
35-751 First Stage Manifold
The first stage manifold is a 3-foot long hose
with identical Foster quick disconnect fittings
on each end. A model-specific adapter is
required to connect the first stage manifold to
the breathing apparatus. The adapter must
be obtained from the manufacturer of the
breathing apparatus, and is typically sold in a
kit that also includes the brand-specific
software.
