Function Description
Operating Instructions
This product adopts RF transmitter/receiver modules and learning code for easy and
convenient operation. The Outdoor Unit is a PIR transmitter. When the Outdoor Unit
detects thermal infrared signals (e.g. moving person), it will send a RF signal to the
Indoor Unit. The indoor unit will then emit two "Ding-Dong" sounds and the LEDs will
flash twice to remind you.

Hi: Turn the warning indicating voume to High level.
Low: Turn the warning indicating volume to Low level.
Silent: Mute with light flashing.
Learning Code
Slide the receiver switch to Hi or Low and then insert batteries, it will emit a
“DingDong” sound. Later, press the “Code” button at the back of the receiver.
Then powerup the PIR transmitter to trigger the working indicator light, which
means a RFsignal has been sent. If the receiver receives the signal, it will emit a
"Ding-Dong"sound and the indicator light will flash to indicate that the code is
learned successfully.
Clearing Code
Press the Code button and at the same time power on the unit, it will give a "Ding
-Dong" tone. Press and hold the Code button for more than 6 seconds, the receiver
will give tones of "Di-Di-Di, Ding-Dong", which means the code has been cleared
successfully.
"Silent" level description: When the receiver
receives the RF signal, no indicating sound will be given but the light will flash for
10 seconds.
Low Voltage Indicating description:
Receiver: When the voltage is lower than 3.3V, the LED light will be on constantly.
PIR Transmitter: When the voltage is lower than 3.3V, the LED light will be on constantly.
Recommended installation height: 1m±0.2m
Warm Tips:
1. When the PIR transmitter is powered on for the first time, it needs 40 seconds
to be ready to work normally. The time interval for each PIR trigger is 12 seconds.
If human is detected within the time interval, the countdown of time interval will
be re-started.
2. The PIR detection range may vary in different working environments, especially
in the area where the temperature is uneven.
