TH-3 WIRELESS TEMPERATURE /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

1. Loosen the screw of the TH-3, then open the

case and place a CR-2/ 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 after changing battery.

2. Select “Installer Mode” on the Base Unit, and enter

Installer Password to gain access authority. Then select \Set Device\Enroll

Device\Special 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 OK!” 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.

3. Press YES, 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. After the Device Enroll is complete, you can go to ”Device Check” to check the

sensors.

Select “Master Mode” on the Base Unit and press YES 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.)

Each time when you press the TEST button on the sensor it will send

current temperature or humidity reading alternatively.
