c. Siren wails 2 times, LED light flashes rapidly. (Means into code-learning mode)
d. Press any button on transmitter once in 10 seconds, when siren wails once means the 1st code
learning is done. After that, press another transmitter any button once in 10 seconds, when siren wails
twice means the 2nd code learning is done. Following the same procedure, it can learn 6 different
transmitter’s code.
REMARK: If the transmitter doesn‘t receive any input in 10 seconds, LED light will distinguish. System
will leave the code-learning mode and enter to user mode automatically.
3. System will Memorize Status Records Prior to Electricity Cut-Off:
Prior to system’s electricity cut-off, system will memorize the status prior to cut-off. At any time, when the
electricity is resumed, system will immediately enter into the status prior to cut-off. If system’s electricity
is cut-off during override status, then system will immediately enter into “override mode” upon the
electricity is resumed. If system’s electricity is cut-off during arming status, then system will immediately
enter into “alarm triggering mode” upon the electricity is resumed.
