ways: "TIMER ON" (CLOSED CIRCUIT ) ," TIMER OFF" (OPEN CIRCUIT) ,and
"IDLE" (no response) For example, if the output device is a light or
a siren, choose "TIMER ON.". So, when "Input 1" triggers, the circuit
relay of the output dry contact will become "CLDSED CIRCUIT", that means
the light will be turn on or the siren will be turned on ; choose "TIMER
OFF". so when "Input 1"triggers, the circuit relay of the output dry
contact will become "OPEN CIRCUIT" that means the light will be turn
off; or choose "IDLE" for no response, Either selection of "TIMER ON"
or "TIMER OFF" will guide you to the next page of the "OUTPUT" action
time length set-up.
The "TIMER ON" or "TIMER OFF" is in accord with the setting of O/P PRESET;
" N.C." in accord with " TIME ON," " N.O." in accord with "TIME OFF"
2. TRIGGER
This is to set the triggering conditions of the input terminal. There
are three settings in the "TRIGGER" sub-menu, "CONDITION", "DETECT"
and "STATUS".
CONDITION: Set the input terminal to be triggered at the "N.O." (OPEN
CIRCUIT) or at "N.C." (CLOSED CIRCUIT) relay condition. When the input
terminal detects OPEN CIRCUIT or CLOSED CIRCUIT it will trigger the
alarm. For example, if the input device is a motion sensor (which is
normally open), choose "N.C." for triggering circuit relay condition.
DETECT: This is to enable (ON) or disable (OFF) the terminal detection
function.
STATUS: This is to set the trigger for one time (ONCE) or continuously
(CONTINUE).
