Alarm Inputs
Four photocoupler inputs are provided for alarm
inputs. Alarm signals can be connected to any of the
inputs as follows.
To use the electrically isolated inputs, the connected
device must have 5 to 20-V DC output, connected as
follows.
If an alarm device has mechanically switched or open-
collector outputs that do not need to be electrically
isolated, connect as follows.
• Refer to the respective manuals for details on setting
up the EVI-D30/D31/G20/G21 and HSR-1/1P/2/2P.
• Please note that specifications and external
appearance may be changed for purposes of
improvement without notification.
