TH-3 WIRELESS'TEMPERA‘TURE [HUMIDITY SENSOR
The "TH-3 is a battery operated wireless temperature/humidity sensor specially
designed for the LS-30 Security System. With its small size and wireless operation,
the sensor can be put anywhere to monitor the temperature and humidity in a room,
a chamber or even a freezer and the reading will be remotely shown on the Base
Unit.
A. Enrolling Code
i. Loosen the screw of the Tl-i~3, then open the
case and place a CR-Z/ 3V Lithium battery
in right polarity.
Important Notice for Changing Battery:
Please press TEST button for 5 seconds to discharge
the energy that remains in the capacitors of TH-3
after removing the old battery. Otherwise. it may not
restart alter changing battery.

2. Select “installer Mode" on the Base Unit, and enter
installer Password to gain access authority. Then select \Set Deviee\Enroll
DeviceiSpecial Sensor\Enter Zone No. to enroll the ID of the TH-3 by pressing
its TEST button.
If the Base Unit receives correct RF code from the sensor, the Base Unit will
issue “Ding Dong" and show “Enroll OKl” on the LCD display.
Now the Base Unit has learnt one type of the two sensors (Temperature or
Humidity sensor), next step is to enroll another type sensor.
Each time when you press the TEST hutton on the sensor It will sen
current temperature or humidity reading alternatively. '
3. Press E enter the Zone number and press the TEST button on the sensor again
to enroll another type sensor.
Note: if LCD shows “Duplicate“ it means the received signal type of the reading
(Temperature or Humidity) is the same as the last reading. You have to go to step
2 to enroll another type sensor again.
4. Afier the Device Enroll is complete. you can go to ”Device Check” to check the
sensors.
Select “Master Mode" on the Base Unit and press ES for “System Check? Or
Hot Key" then select “Device Check“
(There should be two new sensors in the device list, one is Temperature sensor
and the other one is Humidity sensor.)
5. You may change its various attributes under \Set Device\Change Device
‘ Setting\Speeial Sensor to fulfill different requirements.
The sensor can be set as an Alarm Device or a Control Device. (Refer to the
blocks below).
B. Mounting
The sensor can be fixed on the wall by using the mounting bracket or hung by using
the belt that comes with the sensor.
The sensing window should he placed downward to avoid water going into the
sensor compartment directly. To measure the temperature of water, the sensor
should he placed in a watertight plastic bag.
Note: - Do not mount the sensor on a metallic wall or flame, the RF transmission
range will be shrunk due to radio signal attenuation.
- if the sensor is put in a closed freezer, there may be a large reduction in
radio range. The user should move the Base Unit closer to the sensor or
using a signal repeater.
c. Testing
Each time when you press the TEST button on the sensor it will send the cur-rent
temperature (LED flashes once) or humidity reading (LED flashes twice)
alternatively.
D. Temperature/Humidity Limit Setting
Select “installer Mode" on the Base Unit, and enter installer Password to gain
access authority. Then select \Set DeviceiSpecial Sensor Limit Set\Enter Zone
Number and then set High Limit or Low Limit. if the temperature/humidity
reading is over these limits, the LS-30 will issue Special Sensor alarm and
inform the user (Special telephone number should he set).
If both high/low limits are set, the high temperature limit should i7 greater
then the low temperature limit at least for l'C and the high humi ty limit
should be greater than the low humidity limit at least for 5%.
Note: if the sensor works in the temperature over +65°C or below ~25’C for a
long time, the sensor and battery life will be reduced and the
performance may be degraded.
E. Operation and Display
To save battery power. the sensor sends reading automatically only when the
temperature/humidity change is over l'C/3%. if there is no any change for a
long time, the sensor will send the reading hourly to refiesh the display.
If there is any new reading transmitted from the sensor, the Base Unit will keep
the last reading on the display alternatively with the time display each for 5
seconds. You can clear the reading by Hot Key I.
Alarm Device: The system issues alarm when the reading is over the limlts and
issues restore signal when the reading retums to the limits.
