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

limit should be

reater than the low humidit

limit at least for
