Test Method
To test the quality of wireless solar powered alarm wireless beams, we should test 4 parts of the system. They are battery, infrared distance, wireless signal transmitting distance and solar panel charging capability at cloudy and rainy days.
A. Test of battery
The rate voltage of the battery is 4.2V. If the solar powered wireless beam works at illumination under 1600Lx for continual days and the battery voltage is down to 3.8V, the product will activate battery protection system. It will protect the battery from overusing and the solar powered beams don’t work now.
After the battery is recharged to 4.1V, it restart to work. At normal working environment, the battery starts to recharge when voltage is 3.9V and without low voltage protection.
Test 1:
Working time without sunlight
The solar powered beams can work for 20 days without sunlight.
Put the beams with battery installed at place whithout illumination such as drawer, box, then trigger it. The day before receiver terminal indicator doesn’t light on is the last working day.
Test 2:
Battery recharging time
At normal sunlight environment, the battery recharging time is 1 day. (from low voltage to full voltage)
Put the beam with battery installed at place full of sunlight, take down the battery and test its voltage after 1 day.
B. Test of infrared distance
The infrared distance of wireless solar powered beams is 100m
Install the batteries in beams, aiming and then enroll it to alarm panel. Take the transmitter and receiver beams to 100m distance, aiming again, receiver terminal indicator flash slow then flash fast and then light off. Trigger the beams, the alarm panel send out alarm signal.
C. Test of wireless transmitting distance
The distance between wireless beams and alarm panel is 100m (can reach to 1 km with high power)
Put the alarm panel at a place, enroll the wireless beams to the panel, put the beams at another place which is 100m from the panel, trigger the beams, the panel will alarm.
Repeat to trigger the beams to test the stability.
D. Test of solar panel charging capability at bad days
Amorphous silicon solar panel is used for the beams. It enables the beams to be recharged at cloudy and rainy days.
At cloudy or rainy day, put the beam outdoor without battery installed. Place the solar panel towards outside. The beam indicator red LED will keep flashing. That means the solar panel is charging.
The solar panel works via absorbing UV light and can work at illumination level is over 1700Lx. The illumination can reach to 2500-2700Lx with sun light and reach to 2000Lx without sun light.
Notes of using the solar powered wireless beams
1. Trigger way
Only all beams are blocked, the product will trigger alarm. To avoid false alarm by animals and falling down things, the product is designed with required blocking speed. A thicker object such as a book is required for test. Not too fast speed is required to test. Please make sure the receiver indicator lights on when it is triggered. When the product is triggered, the receiver terminal indicator will light on, then light off. Only after it lights off, it will be on work status again for next time trigger. If the indicator is lighting on and now trigger it again, it will not send alarm signal.
2. Aiming
If transmitter terminal and receiver terminal are not aimed, the indicator of receiver will keep lighting on. When they are aimed, the receiver terminal indicator will flash slow, then fast and lights off at last. Now, it is at work status.
3. Alarm Panel
Antenna of the alarm panel should be pulled out totally to ensure the receiving distance.
Remember to enroll the test beams to the alarm panel and arm the panel before test.
Avoid to test and use the wireless alarm products at places which is with high magnetism, high voltage equipment or metal objects.
