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.

Otherwise it may cause electric shock or damage to equipment. CAUTION ! Do not use the products outside the rated power supply voltage range specified in the Specifications. It may cause a fire or damage to equipment. CAUTION ! Do not disassemble, repair, or modify the products. It may cause a fire or electric shock. CAUTION !

2 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. Main unit Outer cover EVA Electrical box Tapping screw Pan head screw 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. Sub Type Input Method Open -circuit Detection Short -circuit Detection Class Interrupt 1 Normally Open Yes No Class B Disabled 2 Enabled 3 Class A Disabled 4 Enabled 5 Normally Close No Yes Class B Disabled 6 Enabled 7 Normally Open Yes Yes Class B Disabled 8 Enabled 9 Class A Disabled 10 Enabled 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.

4 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 0Ω short (for subtype 1-4), 2.2kΩ short (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.
