S&T TPMS1209B, FULL-TIME DIRECT TPMS
TPMS1209B is a full-time direct tire pressure monitoring system which includes one wireless Master and four
screw-on Sensors.
The sensor can be screw inside the tire instead of the valve to sense the pressure and the temperature inside
the tire all the time and transmits the pressure information data to the master by RF technology.
The master can receive and deal with the data and issue different alarms if the tire pressure or temperature is
in an improper state .
S&T TPMS1209B can sense and display the tire pressure and the temperature all the time and can issue an
alarm when the tire pressure or the temperature is at an improper level, so as to notify the driver to treat the
problem and avoid tire busting or tire damage. Through TPMS, the driver can keep the tire running at a proper
pressure so as to avoid excess gasoline consumption and keep the vehicle in an easily controlled state.

2. There are 4 pieces of the 3M Dual Lock Fastener in the packing box, you can choose one to affix on
the bottom of the Master and choose another one to put it on the dashboard, with the remaining two
as spare.
Note 1. If you don't want or you are not convenient to use the lighter plug, the rechargeable battery is an optional
for powering the master. The operation process for battery power is as follow:
1) Take off the cover of the battery box on the back of the Master; 2) Put three rechargeable batteries into
the battery box; 3) Cover the battery box; 4) Turn on the Master.
2. The lighter plug is a special plug with a transformer inside.
3. On some vehicles, the cigarette lighter will power off when the engine powers off. If this happens, or if the
user accidentally pulls out the lighter plug from the lighter, if the rechargeable batteries are already
emplaced inside the Master, and the power of the batteries is enough to operate the Master, the Master
can switch to the battery power mode automatically, with no detriment to the system.
4. If you turn off the Master, the Master can not receive, treat, display and alarm at all.
5.If the Lighter Plug connects to the vehicle power while the car is not used for about 3 months, the vehicle
power maybe exhausted and the car perhaps can not start as usual. So we strongly suggest the user to
pull out the Lighter Plug or turn off the Master if the vehicle will not be used for a whole month or longer.
3.Plug the small end of the Lighter Plug into the socket on the side of the Master, and put the big end of the lighter
plug into the lighter socket of the vehicle.
4.Turn on the Master by moving the power switch.
5.Once the Master starts to work, the screen starts to display the pressure of the four tires in turn. Before
installing the sensors, the pressure & the unit information shown on the screen as “ ---psi”.
1.Take out the Master from the box.
2.Choose a suitable location for the Master on the dashboard platform.
Make sure to first Scrub the surface of the platform with alcohol .Next, strip
off the liner of the 3M Dual Lock Fastener, put the sticky side onto the
suitable location, then fix the Master with another side of the 3M Dual Lock
Fastener on the platform.
Note : 1. In order to stick the Master firmly on to the dashboard, we
strongly suggest the user to scrub the location with alcohol.
3

Note : 1. This product is not applicable to those tires with inner tubes.
2. We strongly suggest the user to go to an Auto Service Shop to install the system.
3. If one of the sensors is broken or fails to work, the others can still function properly, only the broken one
need to be replaced. please detach the broken sensor and follow the above steps to install the new
sensor. Then please follow the ID Number programming steps on page14 to set the ID Number of the
new sensor on the master.
4. The tires need to be Re-balanced after installing the TPMS1209B sensors.

FUNCTION
NOTE:
Usually , the Temperature in the tires will be displayed in turn on the screen. If
need, the Standard Pressure can be displayed on the screen. At this time, the
Temperature will disappear from the screen.

Power Switch automatically
The Master will work normally when powered by batteries rather than the vehicle, in identical fashion.
Auto Sleep mode of the Master
The master can be powered by the vehicle power through the lighter plug or the rechargeable battery.
Vehicle power is strongly recommended.
If the lighter plug inserted the power socket of the Master, even the battery group is also inside the Master
battery box and the power is enough to operate the Master, the Master will still draw power from vehicle power.
But when the vehicle power is off for some reason, the system will switch to the battery power automatically.
If the car parks for more than 10 minutes when powered by the rechargeable batteries, the Master will be
switched into a sleep mode, this can save the battery power. And the alarm for Low Pressure Level 3 can still be
received by the Master within in 7 minutes and issue the alarm when the Master is activated . If powered by
vehicle power, the Master will not switch into the sleep mode, only the LCD shutdown and all kinds of alarm
information can be received by the Master , which can issue the alarm accordingly.
The rechargeable batteries recharged once can work 10~15 days, if the car runs no more than 2 hours a day.

SPECIAL ANNEX
1. LCD operating temperature
For all of the LCD, the lowest limitation operating temperature is-30C, the upper temperature limit for working
mode is 70 for storage the temperature limit is 85 . This is determined by the character of the LCD.
If the LCD works under -30 for a long time, the LCD may be destroyed entirely.
On the Master, there is a LCD screen for displaying the information. In order to use the LCD properly, we strongly
recommend the user to power off the display if the temperature inside the vehicle will be lower than -30 for a
long time.
2. The power consumption
The Master power consumption is very small, only 10-12mAh under the normal mode and 22mAh under the
alarming mode, if the vehicle be used under a usual state, the power consumption can even be ignored.
But if the vehicle parks for some long time, for example three to six month or more, the Master connected to the
vehicle power through the Lighter Plug is still operating, it may consume much power of the vehicle, or even
exhaust the vehicle power. So we strongly recommend the user to pull out the plug and power off the Master if
the vehicle will park for a long time.
3. The work life of the battery group
Under a normal working mode, if the battery volume is 2300mAh. If the car runs for 2 hours and is powered by the
battery every day, the battery group can last 15 days once recharged.
4. Charging the battery
(1) The Batteries can only be charged by a Single-cell charger.
(2) You Can NOT recharge the batteries by plugging the unit into the vehicle's 12V adapter directly.
(3) You can NOT recharge the batteries by removing the Master from the vehicle and plugging the Master
unit directly into an AC adapter.
(4) You MUST recharge the batteries by removing them from the unit and placing them into a battery
charger powered by AC. It takes 16 hours to recharge the batteries back to full power.
(5) The batteries can be recharged with a customer's existing battery charger, because the Master
contains 3 pcs of batteries, the charging requests odd charging positions.
Note : If frequent alarms and frequent pressing the keys happen when powered by the rechargeable batteries,
the working time of the battery group will reduce.

5. Checking and inflating the tire pressure once a certain time
In order to keep your tires' pressure under a standard level, to avoid the slight damage or frequent alarming
while the pressure near the alarm limit, we strongly recommend you to check and adjust the tire every month to
keep the tire pressure under a proper state.
