General Description
EVA-DIP-SCI Dual Input Module with Short Circuit Isolator is intended
for use in addressable two wire systems. The module monitors and
transmits the status (normal, open, short, or active) of devices equipped
with NC/NO dry contacts to a control panel. The initiating device circuit
(IDC) can be wired on Class A or Class B.
Note: Any conventional detector cannot be connected with the module.
General Operation
Normal standby condition: The module receives polling from the control
panel at the regular interval. Polling LED (green) flashes.
Active condition: When an external input is activated, Input LED (red)
illuminates, and the module communicates to the control panel the active
status.
Trouble condition: If an overcurrent occurs because SLC (Signaling Line
Circuit) is shorted, SCI LED (yellow) illuminates, and the module
communicates to the control panel the short status. The module also
communicates to the control panel the open/short status of IDC, depending
on the Subtype Setting described below.
SCI (Short Circuit Isolator) Function
The module has a built-in short circuit isolator. SCI circuit prevents entire
loop failure in the event of a short between L+ and L- on the loop. If a short
is detected between L+ and L-, the yellow LED indicator is illuminated.
The line between Lin- and Lout- is disconnected automatically to isolate
the short circuit, and short circuit status is communicated to the control
panel. Upon removal of the short condition, the module will automatically
connect between Lin- and Lout- to restore the entire loop to the normal
standby status.

Compatibility Requirement
To ensure proper operation, the module shall be connected to UL listed
control panel NFU-7000 series.
Before Installing
Disconnect power to the control panel before installing the module. If the
module is installed in an existing operational system, inform the operators
and local authorities that the system will be temporarily out of service.
Mounting
Mount the module directly to 4’’ square electrical box (UL Listed).
Secure the module to the electrical box, as shown in Figure 3.

Setting
・Address Setting
Use EVA-AD2 Programmer for setting the address of the module prior to
installation. EVA-DIP-SCI has an address given at random from factory.
Connect the Programmer with the address setting port to change the
address to any of 1-254 (dec), with reference to the instruction manual of
EVA-AD2 Programmer. The address can be set regardless of whether
power supply from the control panel is turned on or off. During setting
address, the module does not respond to the control panel.
Set the address of module according to Job data.
・Subtype Setting
Set the subtype depending on the wiring configuration as below. The
subtype is to be set through the Configurator for the control panel.

When interrupt is enabled, it allows a high priority communication to the
control panel. The consumption current increases with this setting.
Note : Applicable subtype setting differs depending on control panels.
Subtype 1 to 10 can be used with the control panel complying with UL864
9th edition.
Subtype 7 to 10 can be used with the control panel complying with UL864
10th edition.
Please contact Nittan customer service for any required details.
Wiring
All wiring must conform to applicable local codes, ordinances, and
regulations.
Install module wiring in accordance with the appropriate wiring diagrams.
Use cable AWG12-22 for wiring. Do not connect different gauge cables
at one terminal in order to prevent loosening. Use a fork terminal for
crimping two cables.
CAUTION
!
Do not connect cables in reverse polarity. Failure to connect the polarity
correctly could result in damage to the module and/or other equipment.
CAUTION
!
Note: All wiring is power-limited and supervised.

Maintenance
Routine inspection: Ensure the module is secure and undamaged.
Operation Test
The purpose of the Operational Test is to confirm the product’s correct
operation.
1) When carrying out site testing of the product, the control panel shall
be set to “one-man-walk test mode” prior to the test.
2) Take any necessary precautions to limit the sounding of the alarm
sounders/bells and any fire service summoning device.
3) Turn on the external inputs connected to the module, and confirm
that the module is in active condition and the input LED (red)
illuminates. Confirm that an active signal is transmitted to the
control panel.
Note: If the test cannot be carried out through the external inputs, test the
area between terminal A+ and A-（or B+ and B-）to check the module. (In
accordance with the subtype setting, set the status either 0Ωshort (for
subtype 1-4), 2.2kΩshort (for subtype 7-9), or open (for subtype 5-6).)
4) After the external inputs have brought the module into the active
condition, reset the external inputs. Confirm that the module goes
back to the initial status after the external inputs are reset.
5) If subtype is set as 1-4, or 7-10, open between terminal A+ and A-（or
B+ and B-）and confirm that the control panel detects the open
circuit. If subtype is set as 5-10, short between terminal A+ and A-（or
B+ and B-）and confirm that the control panel detects the short
circuit.
6) Short between terminal Lin+ (Lout+) and Lin- (Lout-), and the SCI
LED (yellow) illuminates. The short circuit isolator isolates the
devices connected after the short-circuited area, which makes these
devices have no response. Upon removal of the short condition, the
area is automatically connected to go back to the normal standby
status, and the SCI LED (yellow) turns off.
