General Description
EVA-ZMU-SCI Zone Module with Short Circuit Isolator is intended for
use in addressable two wire systems, which can be connected with
2-wire conventional detectors. The module monitors and transmits the
status (normal, open, short, or alarm) of zone with the detectors to a
control panel. The initiating device circuit (IDC) can be wired on Class A
or Class B.
General Operation
Normal standby condition: The module receives polling from the control
panel at the regular interval. Polling LED (green) flashes.
Alarm condition: When an external input is activated, Input LED (red)
illuminates, and the module communicates to the control panel the
alarm 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 operating 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-ZMU-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.

Note : Applicable subtype setting differs depending on control panels.
Subtype 1 to 8 can be used with the control panel complying with UL864
9th edition.
Subtype 5 to 8 can be used with the control panel complying with UL864
10th edition.
Please contact Nittan customer service for any required details.

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) Operate a detector connected to IDC of the module, and confirm
that the module is in alarm condition and the input LED (red)
illuminates. Confirm that an alarm signal is transmitted to the
control panel.
Note: If the test cannot be carried out by operating the detector, test the
area between terminal A+ and A-（or B+ and B-）with appr. 2.4kΩ
resistor to check the module.
4) After the detector has given the alarm condition, reset the detector
from the control panel. It may be necessary to allow a short time to
elapse before the detector is reset.
Note: For detector testing and cleaning information, refer to the
instruction manual of detector.
5) In any subtype setting, 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 5-8, short between 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) is illuminated. 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 operating
status, and the SCI LED (yellow) turns off.
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
!
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.
