User's Manual

B. Mounting
It is recommended to attach the sensor on a flat surface by the Velcro supplied.
Note: Do not mount the sensor on a metal surface, the RF transmission range will
be shrunk due to radio signal attenuation.
If the sensor is put in a closed freezer, there maybe a large reduction in radio range.
The user should move the Base Unit closer to the sensor or using a repeater to relay
the RF signal.
C. Testing
Each time when you press the TEST button on the sensor it will send the current
temperature (LED flashes once) or Analog reading (LED flashes twice) alternatively.
D. Analog /Temperature Limit Setting (also can be done by HyperSecurLink
software)
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 Analog/temperature reading is over these limits, the LS-30 will issue Special
Sensor alarm and inform the user (Special telephone number should be set).
If both high/low limits are set, the high limit should be greater than the low limit
at least for 1 reading.
Note: If the sensor works in the temperature range over +50
℃ to -20 ℃ for a long
time, the device’s life will be reduced and the performance maybe degraded.
E. Operation and Display
To save battery power, the device sends reading automatically only when the
temperature change is over 1℃ or Analog Reading change is over 2 readings.
If there is no change for a long time, the device will send the reading hourly to refresh
the display.
If there is any new reading transmitted from the device, 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)
(High Limit)-1: Alarm Restore
(Low Limit)+1: Alarm Restore
