Alarm Input/Output Signal
Alarm Input Signal
Connect to sensors such as infrared sensors, door
sensors, metal sensors and manual switches.
To prevent noise from entering the internal
0
circuit, supply non-voltage contact signal to the
alarm input signal.
Memo :
You can configure whether to set the alarm when
0
the contact is short (MAKE) or open (BREAK) in
the [Alarm] page of the [Advanced Settings]
page.
(A p.56 [[Alarm] Page] )
Apply such that the alarm signal continues for at
0
least 500 ms. The alarm signal may not be
recognized if it is less than 500 ms.
Note :
Do not supply voltage.

Alarm Output Signal
Connect to alarm devices such as alarm, indicator,
light or buzzer.
Alarm output signal is an open collector output
0
insulated with photo coupler.
Memo :
You can select whether to set the contact to
0
short (Make) or open (Break) during an alarm in
the [Alarm] page of the [Advanced Settings]
page.

Note :
As this terminal is polarized, be sure to connect
0
it such that the voltage of the OUTPUT output is
higher than that of the COM output.
It will be damaged if reverse voltage is supplied.
