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:

The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data.
The data collected is compared with the last data reported. If the data change value 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.
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.
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.

Installation

Installation Location

Assess where needs to detect the cigarette smoke in the building. The places may include restrooms, staircase corridors of exit, storage rooms, meeting rooms, and other places with fewer people. Install the cigarette alarm near the smoking locations, such as the ceiling above the toilet water tank. The installation location should be at least 10 cm away from the wall or corner. If the room has a steep or sloping ceiling, install the alarm at a horizontal distance of 0.9 m from the highest point of the roof, as the Figure.

The installation position of the cigarette alarm on the pitched roof

Inappropriate Installation Location

If the installation position is inappropriate, the alarm is prone to false alarms. To avoid false alarms, please do not install alarms in the following locations.

Do not install in places where burning particles may appear or nearby, such as the kitchen with fewer windows or poor ventilation, the garage which is prone to vehicle exhaust, fireplaces, or around burning heaters and other heaters. Burning particles is a by-product of the burning objects, and it may cause the device to alarm.
In areas where is without air flow, smoke cannot enter the smoke collection box through the air flow caused by the ventilation system to trigger the alarm. Otherwise, please avoid the area where the air flow will bring normal burning particles into the device, such as the kitchen.
In a moist or hot and humid environment, or in an area within 3m from the bathroom, moisture in the air may enter the smoke collection box and condense into water and dew during the cooling process that may cause false alarms.
In extremely cold or extremely hot environments including unheated buildings or outdoors, if the temperature exceeds the limit of device operation temperature, the device will not operate normally.
n a dusty or dirty environment, dust may accumulate in the smoke collection box and cause the device to be overly sensitive. In addition, dust can block the smoke inlet of the device and weaken the sense to smoke.
The high-speed air flow environment near vents, air conditioners, heaters, fans, etc. may keep the smoke away from the device.
The area is without air flow, such as the top part of the building spire, or the top of ceilings and walls. The air is not circulated in these areas, so the smoke cannot enter the device. To avoid this situation, please refer to the Fig. 1. for the recommended installation location.
In areas with a large number of insects, insects entering the device may cause false alarms. Please kill the insects before installation.
The location is near fluorescent lights. The electronic noise caused by fluorescent lights may cause false alarms. Do not install the cigarette alarms within 1.5 meters of fluorescent lights.

Install the cigarette alarm

If the battery is not installed, the base cannot be locked and the alarm will not operate.

Draw a 150 mm long line at the location where the alarm is planned to be installed.
Turn counterclockwise to remove the device mounting base. Please place the main body of the cigarette alarm properly to avoid contamination with dust during the installation process.
Align the mounting holes (two long holes) of the base with the straight line and make the marks.
Remove the base.
Drill two holes with a diameter of 5 mm at the marks, insert plastic expansion screws (included with the device), or use other installation methods (depending on the type of the roof).
Fix the base with the screws included with the device.
Align the mounting hole of the main body with the base, and turn it clockwise to lock it.
Gently pull the alarm outwards to confirm that the device is installed.
Short press the test button, the alarm enters the test state, the LED keeps on for about 3 seconds, and the relay is activated at the same time indicating that the device is operating normally.

It can be taken out from the base if necessary.

Cigarette Alarm Test

Normal Operation Test
After installing the battery according to the correct polarity, the red LED of the alarm flashes at least 8 times and then stays on for about 0.5 second indicating that the battery is installed correctly and the alarm is in normal operation state.
Short press the test button to enter the test state, the LED will keeps on for about 3 seconds, and the relay will operate at the same time.
Alarm Indication
When cigarette smoke is detected, the LED keeps on, and then the relay is activated.
Alarm Threshold
The cigarette alarm provides three levels of sensitivity to adjust (dip switch). In order to achieve the best setting, the sensitivity can be set to medium sensitivity at the beginning. Then, adjust the sensitivity according to the situation, such as false alarms, or no alarming because of high ceilings, excessive airflow and other reasons.
Low Voltage
When the battery is about to be used up, the device will send out a low- voltage alarm, and the LED will flash twice every 45 seconds for at least 30 days. When the low-voltage alarm occurs, please replace the battery immediately.

Note:

RA03A is a combination of R311CA and the cigarette alarm– NB707V-RL. The power of the two devices is provided by separate batteries. R311CA cannot obtain the battery voltage information of the cigarette alarm; therefore, RA03A reports the voltage information which is from R311CA batteries, and does not include the batteries of the cigarette alarm. The low battery information of the cigarette alarm requires regular maintenance to observe the status of the indicator light of the cigarette alarm.
The cigarette alarm is not a fire detector and cannot detect gas, heat, or flame.
Do not use protective covers or similar objects to cover the device.
