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
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
t
current temperature or humidity reading alternatively.
5. You may change its various attributes under \Set Device\Change Device
Setting\Special Sensor to fulfill different requirements.
The sensor can be set as an Alarm Device or a Control Device. (Refer to the
blocks in 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 be placed downward to avoid water going into the
sensor compartment directly. To measure the temperature of water, the sensor
should be placed in a watertight plastic bag.
Note: - Do not mount the sensor on a metallic wall or frame, 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.
C. Testing
Each time when you press the TEST button on the sensor it will send the current
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 Device\Special 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 be set).
Note: If the sensor works in the temperature range over +65℃ to -25℃ for a
long time, the sensor’s life will be reduced and the performance may be
degraded.
If both high/low limits are set, the high temperature limit should be
greater then the low temperature limit at least for 1℃ and the high
humidit
y
limit should be
g
reater than the low humidit
y
limit at least for
E. Operation and Display
To save battery power, the sensor sends reading automatically only
when the temperature/humidity change is over 1℃/3%. If there is no any
change for a long time, the sensor will send the reading hourly to refresh 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 C.
Alarm Device: The system issues alarm when the reading is over the limits and
issues restore signal when the reading returns to the limits.
(High Limit)+1: High Limit Alarm
(High Limit)
(Low Limit)
(High Limit)-1: Alarm Restore
(Low Limit)+1: Alarm Restore
(Low Limit)-1: Low Limit Alarm
Control Device: The reading from this device will not issue any alarm even
over the limits.
Depends on the setting of High/Low limit operation, it can
control the operation of the switches or the Relay output.
High Limit Operation: Turn on at high limit reading and turn off at
low limit reading, to control all kinds of freezer or
dehydrator.
Low Limit Operation: Turn on at low limit reading and turn off at high
limit reading, to control all kinds of heater or humidifier.
