General Description
The EV-2I O (-EU) Dual Input / Single Output Module is an addressable input/output
module with short circuit isolator. The module provides two supervised inputs (Class B) and
one dry contact relay output rated at 5A@240Vac. The EV-2I O uses UK 2-gang box with
surface and flush mount options, and the EV-2I O-EU uses European 503 electrical box
flush-mounted.
Two inputs are monitored to detect normal/input/open/short state, which can be used as
general purpose inputs.
The relay output is used for the control of equipment such as dampers and extractors for
ventilation or smoke control system. The relay contact is monitored to detect the
condition (on /off /relay stuck).

Address Setting
Loosen the Allen key screw to open the access door in the front, using the .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 ).
Use EV-AD2-EXT to set the address of the EV-2I O (-EU). The factory default address of 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 -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 Switc Operation
With DIP switch , it is possible to select normal mode or failsafe mode (refer to Table
and Figure ). 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.

Connections
General Operation
Standby condition: The module receives polling from the control panel at the regular
interval.
Input condition: When the monitored contact switches into an input state, the module
reports the state to the control panel.
Output Operation: On a command from the control panel the output relay will change
state. It is possible to set the relay to “Failsafe” mode, where it will also change state if loop
power is lost.
Fault condition: The module reports to the control panel on an open or short circuit in the
input circuit and relay stuck in output circuit.
SCI in active condition: When SCI is activated to isolate a short circuit in the loop, the LED
on the module illuminates yellow.
Interc angeability wit Existing Products
It is necessary to update the software of the control panel to respond to EV-2I O, prior to
the replacement of the existing model EV-SIO. The EOL resistors will also need to be
changed.
SCI Function
The EV-2I O (EU) has a built-in short circuit isolator. The SCI circuit prevents entire loop
failure in the event of a short between L+ and L- on the loop. If a short circuit is detected,
the section of line containing a short circuit is automatically isolated. If not required the
Isolator can be bypassed using the Jumper provided.
Service and Maintenance
Inspection and tests of the module shall be carried out periodically according to the
requirements of BS 5839 Part , Fire Detection and Alarm Systems for Buildings: Code of
Practice for System Design, Installation and Servicing, or equivalent local codes of
practice.
For a routine inspection, ensure the module is secure and undamaged.
When carrying out site testing of the module, set the Fire Alarm Control Panel to test mode
and take any necessary precautions, so as to limit the activation of alarm sounders/bells
and any fire service summoning device.
