Fire Safety Installation Instructions Model NIM-W Network Interface Module MXL NETWORK INTERFACE APPLICATIONS OPERATION The SIEMENS Model NIM-W provides a new communication path for the following uses: as an MXL networking interface as a connection to Foreign Systems as a connection to Air Sampling detectors When used as a networking interface the NIM-W supports the connection of up to 6 MXL Systems. This new network also supports a Network Command Center (NCC) that monitors all the MXLs in the networked group. Output logic between MXL panels is done using CSG-M programming. CSG-M versions 6.0 and higher include options for networked MXL Systems. Each MXL System is assigned a panel number. This panel number allows interactive programming between panels using CSG-M. INSTALL JUMPER PLUGS IN ORIENTATION AS SHOWN. POSITION M SHOWN SELECTED. M W The NIM-W supports both Style 4 and Style 7 connection. In the event of an NIM-W communication failure, each MXL System continues to operate as a standalone panel. The NIM-W can also be configured as an RS-485 two wire interface to foreign systems. This operation is called FSI (Foreign System Interface). The FSI responds to a protocol and gathers information about the MXL status. The interface supports both single MXL Systems and networked systems. Typical use of this interface is between the MXL and building management systems. Use the CSG-M to enable the functions accessed by the foreign system. If the foreign system is UL 864 listed with the MXL, the interface can also be enabled to support control of the MXL including the commands to acknowledge, silence, and reset. For configurations that require both MXL networking and a foreign system interface, two NIM-W boards are required in the MXL System supporting the foreign system interface.

To close a slide switch, push the slide to the side marked ON. The NIM-W also provides for the connection of up to Air Sampling detectors. The MXL supports individual programming and monitoring of the Air Sampling devices. Each detector can be uniquely programmed from the MKB menu or by using CSG-M. All three alarm levels (PreAlarm, PreAlarm 2, and Alarm) are supported. NOTE: When the NIM-W is configured as an Air Sampling interface, it cannot support either MXL networking or the FSI. If these functions are required, additional NIM-Ws must be used. INSTALLATION Remove all system power before installation, first battery and then AC. (To power up, connect the AC first, then the battery.) The NIM-W installs into the MXL optional /2 card cage where it occupies one full width slot. The NIM-W can be installed in either of the full slots of the /2. The slot determines if the wiring is connected to TB or TB4 of the /2. Setting the Switches Set all switches, configuration jumpers, and connection cables before installing the NIM-W into the. Use switch SW to set the MXL network address. Set this switch according to the address where the NIM-W is installed in the MXL s network map. Refer to the CSG-M configuration printout for the address of the module. See Table for settings. Use switch SW2 to set either the panel number for networked systems or to select FSI or Air Sampling operation. Refer to Table 2 for panel settings, Table for FSI settings, and Table 4 for Air Sampling settings.. When installing the NIM-W in a networked system, set the panel number to agree with the panel number for the NIM-W assigned to the MXL System in CSG-M. 2. Switch position 8 selects Style 4 or Style 7 operation for the NIM-W network.. Set jumper plugs on JP4 to the "M" position. Set jumper plugs on P6 to the "X" position.

ELECTRICAL CONNECTIONS NIM-W Network Figure 2 shows the wiring diagram for the NIM-W network. Up to 2 MXL Systems can be connected in the network with an NIM-W installed in each MXL System. For the highest level of fault protection, install the NIM-W in the enclosure with the MMB, although this is not necessary. When connecting more than 2 MXL Systems, an REP- repeater or D200CP is required. Refer to the REP- Installation Instructions, P/N 5-092686, or the D200CP Installation Instructions, P/N 5-092882, as applicable, for the wiring diagram. The network can be installed as either Style 4 or Style 7. Figure 2 shows which wires must be added to support Style 7. Style 7 is required in Canada. Each NIM-W is shipped with two 20 ohm EOLRs only two are required for each network pair. Install an EOLR at the ends of each network pair. Do not install an EOLR at each NIM-W. (For a simple rule of thumb, an EOLR must be installed where only a single wire lands on a screw terminal.) Do not T-tap the network wiring. If T-tapping is required, use the REP- repeater. Refer to the REP- Installation Instructions, P/N 5-092686, or the D200CP Installation Instructions, P/N 5-092882, as applicable, for the wiring diagram. For Style 4 wiring, terminate the secondary network pair (terminals and 4) on each NIM-W with an EOLR. Network Command Center (NCC) Figure shows the wiring to the NCC. To connect the NCC, observe the following restrictions:. Give the NCC a panel number. (This panel number is in addition to the panel number for the MXL System that the NCC connects to.) 2. The total number of panels in the network must not exceed 64, including the NCC. 2 4 5 6 7 8 9 0 2 4 5 6 SEE NOTE 9 NIC-C (IF USED) ONE SLOT OF CC-5 7 8 9 20 2 22 2 24 NOTES:. 8 AWG minimum. 2. 80 ohms max per pair..

Foreign System Interface (FSI) The FSI installs on TB or TB4, terminals and 2, of the /2 depending on where the NIM-W is installed, as shown in Figure 4. Use one of the EOLRs provided with the NIM-W on terminals and 2. This properly terminates the FSI. Use the second EOLR on terminals and 4. Never use terminals and 4 to connect to the FSI. Refer to Figure 4 for the polarity of the FSI driver. If multiple FSI connections are required, up to four NIM-Ws may be installed in an individual MXL System. In networked systems each MXL can support up to four FSI ports. For networked systems, each FSI port must be configured as either local or global in the CSG-M. Local FSI ports display information only on the MXL System to which they are connected. Global FSI ports display all events in all MXL Systems. Refer to the CSG-M Manual, P/N 5-0908, for further information. Air Sampling Interface AnaLASER Interface The AnaLASER Air Sampling interface connects to the /2, TB or TB4, terminals and 2, depending on where the NIM-W is installed (Refer to Figure 5). Up to Air Sampling detectors can be connected to a single NIM-W. The ACC- requires an RS-485 to RS-22 converter which mounts in the back of the ACC- enclosure. The converter model number is AIC-4Z. The AIC-4Z supports from one to four AnaLASER detectors. Refer to the AIC-4Z Installation Instructions, P/N 5-09792, for the mounting and configuration of the converter and the ACC-s. Complete wiring of the converter as shown in Figure 5 before installing the ACC- in the enclosure. Place the end-of-line resistors in the locations specified in Figure 5. Install the cable P/N IC-2 between the converter and the ACC-. Refer to the AnaLASER Air Sampling Smoke Detection Manual, P/N 5-09289, for connection to the AnaLASER detector and power supply, as well as mechanical mounting of the ACC-. NOTES:. 8 AWG minimum. 2. 80 ohms maximum per pair.. Use shielded twisted pair. 4. Terminate the shield at the NIM-W enclosure only. 5. Power limited to NFPA 70 per NEC 760. 6.

VESDA Interface The VESDA Air Sampling interface connects to the /2, TB or TB4, terminals 2-6, depending on where the NIM-W is installed (Refer to Figure 6). Up to Air Sampling detectors can be connected to a single NIM-W. The VESDA/MXL-IQ Intelligent Interface requires a model CPY-HLI which consists of an MXL-IQ/VESDA High Level Interface and a VESDAnet Socket. The CPY-HLI can support up to VESDA detectors utilizing a VESDA network. Refer to the CPY-HLI Installation Instructions, P/N 5-099200, for mounting and installation of the CPY-HLI to the VESDA detectors. Complete wiring of the Intelligent Interface as shown in Figure 6. Place the end-of-line resistors in the locations specified in Figure 6. Install the 5 leads of the Model CPY-HLICABLE interface cable (P/N 500-6999) to the /2 according to the CPY-HLI Installation Instructions, P/N 5-099200. (Refer to Figure 6.) To connect the CPY-HLI to the VESDA network, refer to the CPY-HLI Installation Instructions, P/N 5-099200. NOTE: VESDA is supported in NIM-W firmware version 2.0 and higher, SMB ROM version 6.0 and higher and CSG-M version.0 and higher.
