6. IN ᧶ 2 channels sensor input the rising or falling edge of level of channel S1 or channel S2 can
trigger alarm. The method of application is that connects port S1 or S2 with a 47K Ohm resistance,
and then connects with a 12V power supply, and parallel connects with the alarm flip-flop.
Connect one side of flip-flop with S1 or S2, connect another side of flip-flop with panel power
GND or +12V power terminal.
