4. Connect one end of the Tygon tubing to
the bottom of the head and the other end
to the brass hose barb located inside the
bellows chamber.
This tubing is used to connect the static
pressure port in the left eye of the test
head with the Low Pressure and Activation
Pressure transducers located on the
inside of the Posi3 USB chassis.
5. Carefully align the test head with the
mounting standoffs, and slide the head
into place on the Posi3 USB chassis.
Make sure the Tygon tube from step 4 is
not caught or pinched as you slide the
head into place.
6. Install the four tightening knobs on top of
the threaded standoffs by hand.
No tools are necessary. Do not over
tighten!
5.2 Connect the Posi3 USB to the
PC
The Posi3 USB is connected to the PC via

Turn on the power

To turn the Posi3 USB on, simply plug the
power cord of the Posi3 USB into a grounded
outlet and flip the rocker switch located on the
rear panel of the Posi3 USB chassis.
Note: Honeywell Analytics recommends
that the Posi3 USB be plugged into a surge
protector. Failure to use a surge protector
may lead to sporadic loss of
communication between the Posi3 USB
and the PC.
Do not attach the
pressure-reducing manifold, or mount an
SCBA facepiece on the test head prior to
turning the Posi3 USB on. Doing so prior
to completion of the electronic self test
and startup sequence may result in
damage to the Posi3 USB and/or incorrect
test data.
The USB Drivers must be installed prior to
launching the Posi3 USB software. The USB
driver installation is covered in section 4.1
above (see step 21) and is also discussed in
the Posi3 USB Installation Help File.
5.4 Install the microphone
(optional)
If the Posi3 USB includes the Sound
Detection System (SDS), the microphone will
need to be installed prior to launching the
software.
1. Plug the microphone into the port located
on the Posi3 USB's left front panel over
the medium pressure inlet.
Microphone and Carrier Arm Assembly
2. The software will automatically recognize
the microphone when the Posi3 USB is
initialized.
The microphone is only used in the
Complete SCBA Test. For further
instructions on using the microphone, see
the Posi3 USB Help File.
