Summary
PressurePro :
 Is a wireless electronic tire pressure monitoring
system (TPMS) designed to display tire
pressures.
 Capable of displaying current tire pressures on
demand, whether moving or stationary.
 Is a monitoring system and will not prevent
tires from losing pressure or failing.
 Consists of two basic components.
Display/Monitor and Tire Sensors.
Monitor:
 Shows individual tire pressures and location on
vehicle.
 Can alert the driver via an audible and visual
signal of a low or high pressure situation.
 Wired to battery “Master” switch for power.
Tire Sensors:
 Screws onto valve stem of the tires.
 Transmit a coded RF signal if pressure drops or
increases.
 Reads tire pressure 12,343 times each day (every
7 seconds).
 Transmits updated readings to the monitor
 Sealed non-replaceable battery. (Fire Shop)
Note: Some of the Sensors transmission may be
interfered with because of the following:
 Quirks of RF transmissions.
 Outside interference.
 Signal reception.
Due to these facts PressurePro is not meant to
function as a pressure gauge or a low pressure
indicator. PressurePro is a tire pressure
monitoring system that displays tire pressures
and which, when a signal is received, will signal
low pressures.

Normal Mode:

Monitor is in Normal Mode when first powered up (Battery master
switch on).

Monitor is listening for sensor updates and alerts in Normal Mode.

Green light below “SET” button flashes every 5 seconds.

Tire pressures can be displayed by selecting a tire with the “UP” or
“DOWN” arrow button.

Note: Once the arrow “UP” or “DOWN” button has been
depressed the current Tire location will flash (All other tire position
indicators will be solid) and the current pressure will be displayed.
If there are three dashes in the pressure display, that means it has
not updated the pressure from the tire sensor. It can take up to 5
minutes to update the pressure. This is normal and if there is a
change in the tire pressure it will send the info immediately to the
monitor.

Program Mode (Fire Shop Use Only):
 Used for programming sensors to the monitor.
 When in program mode green light is solid

First Stage Low Pressure Alert
 (Alerts at 12.5% pressure loss from initial
pressure installation).
 A first stage alert will “Beep”, and flash tire
location, and display low pressure - once per
second – until the low pressure is corrected or
the “SET” button is pressed putting the
Monitor in “Reminder Mode” .
Pull over, inspect tire and repair. If no button
is pressed to mute system – system will
continue to alert.

Second Stage Low Pressure Alert
 (Alerts at 25% pressure loss from initial
pressure installation).
 A second stage alert will “Beep”, flash tire
location and pressure value twice per second.
 If no button is pressed to mute system system will alert until low pressure is corrected
or for a total of 15 hours.
Pull over, inspect tire and repair.

Reminder Mode:
 To “Mute” the audible alert, place into

briefly.
 The audible alert will sound periodically.
 The tire position indicator will continue to flash
for the affected tire position.

“Signal Check-in” Feature
 Sensors send short millisecond “Check-in” signal
bursts regularly.
 As with RF devices, a signal may be lost or
interrupted.
 IF signal is lost or interrupted, the monitor will
light that wheel location with a solid light – (There
is no alert beep).
 If this type of alert continues, it may indicate a
sensor has been removed, lost or damaged or a
signal is not being received – check that sensor’s
location.

Multiple Low Pressure Alerts
 In the unlikely event that multiple alerts occur,
the monitor will flash all low locations with low
pressures.
 When selected, a tire location with an alert will
flash its pressure and position while the alert
sounds. (Non-selected low pressure tires will
flash their wheel location every 2 seconds.)
High Pressure Alerts
 Alerts at determined percentage over initial
pressure at installation of sensors.
 The factory setting for this alert is at 24% over
initial tire pressure at installation.

Checking Tire Pressure (Monitor)
 Sensors send an updated pressure reading
approx. every 5 minutes. Pressing the “UP” or
“DOWN” button, (Monitor in Normal Mode), will
select a tire location to display.
 The current tire position will flash and the
pressure will be displayed. If the monitor
displays three dashes then it can take up to 5
minutes to display current pressure.

Manually Checking Tire Pressures and Inflating Tires

With a quality pressure gauge and tire at ambient temperatures. (Cold
pressure, not driven)

Locate tire pressure recommendations on Vehicle Manufactures’ I.D. Plate
on driver’s side door jam.

Remove sensor, (Monitor will now read “00” and give an audible alert),
check pressure, and inflate if necessary.

Replace sensor back onto valve stem, there should be the sound of air
escaping the valve, continue until sensor stops leaking air and is hand
tight.

The display will now read the current air pressure.

Leaving a sensor off for more than 60 seconds sets a new
pressure level – alert level will now be based on new pressure.
Note: Sensors are programmed to represent the tire position on the
monitor/display. Do not remove more than one sensor at any
time.
Daily/Weekly Tire Pressure Checks (PressurePro installed vehicle
systems)



Inspect tires for visual damage or wear.
Check PressurePro Display to see current tire pressures.
If at any time the PressurePro System goes into any system alerts, check
the following items.
1. Check tire for any signs of visual damage.
2. Confirm sensor is on valve stem and is on tight not leaking. (Check for
leaks with a solution of 1 part liquid soap to 2 parts water - look for
bubbles which indicate a leak)
3. If both items are OK, remove sensor and check tire pressure with a
mechanical gauge.
4. If tire pressure is OK then replace sensor within 60 seconds and see if
alarm disappears.
5. If tire pressure is low and above items verified, inflate tire to correct
tire pressure and reinstall sensor. (see warning)
6. If this does not correct sensor alarm. Notify Fire Shop for further
information, thru proper chain of command.
WARNING: Due to the fact that checking and removing the
sensor for more than 60 seconds relearns the current tire
pressure once the sensor is replaced, there is a high probability
the tire is not cold and a false pressure setting will result. The
Fire Shop will be responsible at PM time to correct and reset tire
pressure/sensors when tires are still cold.
Sensor Transmits when these events occur:
 Within 60 seconds of screwing sensor onto the
valve stem.
 Every 5 minutes while updating, under normal
conditions.
 At 12.5% drop from baseline pressure.
 At 25% drop from baseline pressure.
 At the Upper Pressure alert level 25% above
baseline pressure.
 When a sensor is removed from its valve stem.
The PressurePro Tire Sensor should ONLY be
removed when:
Alarm is sounding
 Low tire pressure problem
 High tire pressure problem
 Malfunctioning tire pressure monitor system

If any question or issues reference the owner’s manual
first, then Fire Shop.
