The Dome support 4ch alarm input, 2ch alarm output, in which 1ch and 2ch belongs to "No Alarm
Signal Funtion"，3ch and4ch belongs to alarm On/Off 。It alarms according to their grade(1ch is the
highest grade and 4ch is the lowest) and each Alarm act and Alarm out can be set respectively. The users
can choose whether we use Tri-state alarm function by the seventh DIP of SW3 DIP switchaccording to
the practical situation.（Concerning the details, please refer to Appendix SW3DIP Switch Instruction）
The dome will carry out the following items while alarming：
Execute the programmed Alarm act function. For example, if the alarm No.3 is activated,
alarm act function is preset 2, then the dome will monitor preset 2 immediately.
Alarm output channel output on-off set，switch on external alarm equipment
If the dome receives many alarming signals at the same time, it will alarm one by one
according to their priority from highest to lowest ranks. For example, if the dome receives a
lower alarming signal when it is carrying out the alarming signal in the high rank, the dome
itself will memorize and save the lower alarming signal and execute it after the dome
terminate the higher alarming signal.
Instruction：
On-off Alarm：It has two situations-Open & Short Circuit.when alarm channel and alarm public
point is "open", then won't make alarm; if it is "short", then make alarm.
Tri-state alarm：It contains three state-high/low/middle potential. It is n't transferred by On-Off,but
voltage.when we use tri-state alarm, we should contact one 2.2resistance between
alarm signal line and public point.Drawing as follows： 2.2K connect（a） is
middle potential，belonging no alarm function；2.2K connect（b） is high
