VK7SLEI1010000PStair Night Light Unit A (TX)

PIR RF Staircase/Hallway Night Light System User manual The product is a PIR RF Stair Night Light System, it consists of 2 Unit, Unit A PIR RF transceiver and Unit B Receiver Unit A is a PIR motion detector, when motion is detected within 2 meters area from Unit A, Unit A transmit a 315MHz ASK coded signal of approximate 1 second, and the LED light of Unit A will power on for about 1 minute, then the LED goes off automatically. The Unit B will aslo power on the LED light for about 1 minute after the RF signal from Unit A is received. 315MHz receiver function is deployed in the 2 Unit A, when a Unit A received RF signal from the other, the LED light will power on for about 1 minute. CDS photosensitive detector is deployed in Unit A, and Unit A operates only at night and in dark places. Power supply: AA alkaline * 3 (4.5V) Installation height: approximate 30-50cm Installation location: Unit A- top and bottom of the stairs, Unit B- staircase Operation description: After the battery is installed in Unit A, when the illumination intensity is under 0.15LUX and motion is detected by the PIR sensor within 3 meters from the Unit, Unit A transmit a 315Mhz ASK modulated RF signal. The signal is received and decoded by another Unit A or Unit B, if the code received is identical to the code stored, the LED light is power on for 60 seconds, then goes off automatically.
