FUNCTION
OPERATING GUIDE
The alarm system adopts professional wireless
transmitting and receiving module with learning code,
which enables easy and convenient operation. The
Outdoor Unit is a passive infrared sensor. When the
Outdoor Unit detects thermal infrared signals (e.g.
moving person), it will send wireless signals to the Indoor
Unit. The indoor unit will emit “ding-dong, ding-dong”
sound and the LEDs will flash twice to warn you.
1. There are two switches on the indoor unit.
ON/OFF: As the name suggests, this switch turns the
Indoor Unit ON or OFF.
HI/LO: Change the volume of the chime between high
(HI) volume and low (LO) volume.
2. Code Learning
Insert batteries into the Indoor Unit, the unit will emit
ding-dong sound and flash once to let you know the
batteries have been installed. Next, press the Coding
button at the back of the indoor unit and then insert
batteries into the Outdoor Unit. The Outdoor Unit will
give off red light and send out wireless signals. After
the Indoor Unit receives the signals, it will emit ding-
dong sound and flashing light, which indicates the code
learning is successful.
3. Code Clearing
Press and hold the coding button and then power on.
After 11s, let go after you hear one “DI” tone. Then after
4s you will hear “Di Di Di DingDong” tone which indicates
successful code clearing.
