ACCESSORIES

The LS-30 system includes a full range of accessories, so you can
customize many feature of your security system.
All the radio transmitters used in the LS-30 system, except the Remote
Controller, have a unique random code that is set by the factory with
16,777,216 combinations in total. Also with specially designed
transmission timing control, the LS-30 system can effectively prevent
mutual interference from other transmitters in the system. The Remote
Controller uses copy-preventing hopping-code technology, changing its
radio code every time you press the button. The combinations possible
through this hopping-code are up to 7.3 X 1019. To comply with the
regulations in most countries, radio power is limited to below 10mW, and
effective range is about 100 meters measured at open field. The range may
be somewhat less indoors, depending on the layout of building construction
and furniture.
You may enroll all the wireless accessories and change their related settings,
either through the guidance of the interactive LCD display on the Base Unit
explained in the “INSTALLATION” section that follows, or by using a
computer with the proprietary software “HyperSecureLink” through an
interface adapter, which offers a quicker and simpler way to perform the
installation in.

NOTE: The changes or modifications not expressly approved by the
party responsible for compliance could void the user’s authority to
operate the equipment.
The comply with the FCC RF exposure compliance requirements, this
device and its antenna must not be co-located or operating to conjunction
with any other antenna or transmitter.
This device complies with Part 15 of the FCC Rules. Operation is subject
to the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.

TH-3 WIRELESS TEMPERATURE /HUMIDITY SENSOR

t

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.

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

current temperature or humidity reading alternatively.

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.)
