EV-2I1O (-EU) Installation instructions
IIS-EV-2I1O (-EU) Issue 4 04/03/2019
Address Setting
Loosen the Allen key screw to open the access door in the front, using the 1.5mm Allen
key provided. It is possible to configure the address setting and change the setting of DIP
switch or jumper pin (refer to Figure 1).
Use EV-AD2-EXT to set the address of the EV-2I1O (-EU). The factory default address of 1 is
given to the module. Connect the EV-AD2-EXT to the address setting port with the Micro
USB cable for the programmer and change the address to any of 1-254, with reference to
the instruction manual of EV-AD2-EXT programmer. (Note that the number of available
addresses can be less depending on a control panel model.) The address can be set
regardless of whether power supply from the control panel is turned on or off.
Address setting is possible even after connecting the module to the Loop.
DIP Switch Operation
With DIP switch 1, it is possible to select normal mode or failsafe mode (refer to Table 1
and Figure 1). The DIP switch 2 can change the input setting (normally open/ normally
closed).
If the loop power supply is off, the relay is activated in the failsafe mode. Refer to Table 2
for the relay position in each condition in the normal/failsafe mode.

LED Operation
Five LEDs are visible through the translucent access door of the enclosure (refer to Figure 2
and Table 3).
Polling LED: flashes green during polling from the control panel.
Input LED: illuminates red to indicate that an input is activated.
Output LED: illuminates red when the output relay is on after receiving a command from
the control panel.
Fault LED: illuminates yellow when a fault condition, i.e. an open or short circuit in the input
circuit, or relay stuck fault is detected in the output circuit.
SCI LED: illuminates yellow when a short circuit is detected in the loop and the short circuit
isolator (SCI) is activated.
