Example for MinTime/MaxTime logic:
Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange=0.1V

Note: MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless BatteryVoltageChange value.

Example#2 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.

Example#3 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.
Notes :

1. The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data.

2. The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange value, the device reports according to MinTime interval. If the data variation is not greater than the last data reported, the device reports according to MaxTime interval.

3. We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the device wakes up frequently and the
   battery will be drained soon.

4. Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime interval, another cycle of
   MinTime/MaxTime calculation is started.

IR Delay Configuration

If someone or animal is moving in the monitoring area, RB11E will detect the infrared signal and the red indicator will flash once. In the meantime, it reports occupied status (at the same time, other sensor status value is also reported).
To save the power, when RB11E detects the infrared signal, it will enter IRDetectionTime period. If there is no infrared signal detected in IRDetectionTime period. It will report un-occupy.
IRDisableTime is the sampling period during IRDetectionTime (IRDisableTime are 30 seconds by default setting that PIR is off for first 70% of the period; on for rest 30% of the period).
For example, after triggered, the PIR will turn off the infrared probe for 21 (30 * 70%) seconds to save the power, living objects within this period will not be detected. PIR will re-open detection function after 21 seconds, if it detects living objects in this period, the IR delay time will be extended for another 30 seconds till no infrared signal is detected and
IRDetectionTime period is due and RB11E will then report un-occupy.
The infrared sensitivity adjustment knob can be manually adjusted to change the sensitivity of the infrared detection.
When the clockwise rotation, the higher the infrared sensitivity, the easier it is to trigger.

Disabletime and Detectiontime
IRDisableTime is the sampling period, and IRDetectionTime is the detecting period.
To save power, the sensor will be in the sleep mode for the first 70% of the IRDisableTime and awaken for the last 30% of the
IRDisableTime.

• If living creature is detected during the last 30% of IRDisableTime, the IR delay time will be extended for another
  IRDetectionTime till no infrared signal is detected.

• If no living creature is detected during IRDetectionTime, RB11E will report “unoccupied” along with other sensor status, such as temperature, illuminance, etc.

Example1:

The IRDetectionTime is 60 seconds and the IRDisableTime is 30 seconds, no living creature is detected during the two 9-second detection period (the yellow parts shown below).
RB11E will report “unoccupied” after 60 seconds (IRDetectTime).

Example2:
The IRDetectionTime is 60 seconds and IRDisableTime is 30 seconds, living creature is detected at the 25th second of the first 30 seconds.
RB11E will restart the IR detecting procedure(IRDetectionTime).
No living creature is detected during the next IRDetectionTime and RB11E therefore report “unoccupied.”

Installation

The applicable fixing method can be selected according to the installation environment.

1. Fix with the double-sided tape

Installation requirements

Installation ambient temperature: -20C° ~ 55°C

1. Indoor use only, please check the installation places. The correct installation should follow below conditions.

The sensitivity of the PIR sensor has a lot to do with the motion direction of the human body. The PIR sensor is more sensitive to vertical motions, while it is less sensitive to horizontal motions. Thus, it is important to choose the proper location for installation and higher sensitivity.

Detection coverage

IR coverage range:
The coverage area A- Distance: 11 meters; sensing angle: 30°
The coverage area B- Distance: 8 meters; sensing angle: 60°
The coverage area C- Distance: 5 meters; sensing angle: 120°

Information about Battery Passivation

Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density.

However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high. This lithium chloride layer prevents rapid self-discharge caused by continuous reaction between lithium and thionyl chloride, but battery passivation may also lead to voltage delay when the batteries are put into operation, and our devices may not work correctly in this situation.

As a result, please make sure to source batteries from reliable vendors, and the batteries should be produced within the last three months.

If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis.

To determine whether a battery requires activation

Connect a new ER14505 battery to a 68ohm resistor in parallel, and check the voltage of the circuit. If the voltage is below 3.3V, it means the battery requires activation.

How to activate the battery

• a. Connect a battery to a 68ohm resistor in parallel
• Keep the connection for 6~8 minutes
• The voltage of the circuit should be ≧3.3V
