Notifier NCM Installation Document

12 Clintonville Road CT 06472 1653 USA Installation Document Communications Module NCM W NCM F 51533 A1 03 171 Product Overview Network Communications Module NCM provides a means for connecting specific Notifier fire control products to NOTI There are two types of NCMs available NCM W for nodes with twisted pair wire and NCM F for connecting nodes with fiber optic cable The Network Communications Module for Wire NCM W Supports twisted pair wire medium Fault NFPA Style 4 Class B operation or NFPA Style 7 Class Two programmable data thresholds Transformer coupling provides electrical isolation Pluggable terminal wiring with strain relief Pluggable service connector feeds signal directly B nodes operation A TERM A B TER M B HI HI 0 1 STATB PULSE1 POW ER used 1 NCM W in the event that power must be removed from a 312.5 Kbaud transmission rate Data is regenerated at each node Two network ports to allow simultaneous connection to alarm control panel and to programming computer Enables software and database upload download over Refer to the NOTI Manual Network 4.0 and Higher for wiring length and threshold The Network Communications Module for Fiber NCM F B Supports fiber optic medium NFPA Style 4 Class B or Style 7 Class A operation Data is immune to all environmental noise Optical isolation prevents ground loops NOTI fiber optic medium Fiber type 62.5 125 micrometers multimode 8 dB limit 50 125 micrometers multimode 4.2 dB limit Wavelength 1 820 nanometers Use standard 850 nm Connectors ST Style ST is a registered trademark of 312.5 Kbaud transmission rate Data is regenerated at each node Two network ports to allow simultaneous connection to alarm control panel and to programming computer Enables software and database upload download over used 2 NCM F Installation PN 51533 A1 03 27 03 wiring consecutive NCM W boards note that wiring may enter or exit at Port A or Port B as in Figure 4 NCM W port to port wiring is not polarity sensitive The use of Port A or Port B is An NCM W may be connected to any of the following devices Installing the NCM Interconnecting the NCM W MIB W MIB WF NAM 232W NCM W in another panel NCS W network connection RPT W RPT WF information regarding these devices refer to the documentation listed in Table 4 last node A next node B A A B TERM B A TERM A B TERM B A TERM A Wiring from the NCM W that is installed outside the building Cannot exceed 1000m 3280 ft Must be in conduit and is to be buried in a trench separate from any power lines Cannot cross any power lines 3 The NCM W Ground Driver Receiver Driver Receiver Driver Receiver Driver Receiver 1 NOTI Connections NCM W Functions Ground Fault Detection and Line Termination NCM W provides two sets of switches to simplify setup in Figure 4 all are in the position B TERM B A TERM A Enable ground fault detection by setting SW103 for Channel A and for Channel B Activate on board end of line resistors by switches SW100 for Channel A for Channel B Correct configuration depends on your network refer to the NOTI Manual Network Version 4.0 and Higher 4 NCM W Switches Installation PN 51533 A1 03 27 03 Interconnecting the NCM F connecting consecutive nodes repeaters note that fiber cable must exit one board on transmit and enter the next node repeater on receive RX Also note that the fiber optic pair RX TX port A of one Node Repeater may be connected to either Port A or Port B of another node repeater to Figure 5 An NCM F may be connected to any of the following devices MIB F MIB WF NAM 232F Another NCM F Network connection for NCS F RPT F RPT WF information regarding these devices refer to the NAM 232 and Repeater manuals listed in 4 Documentation See the NOTI Manual Network Version 4.0 and Higher for maximum fiber cable attenuation RxA RxA 5 NCM F Connection A A B B Mixing Wire Fiber on One Network 2 NOTI Connections NCM F some networks it may be necessary to mix twisted pair wire and fiber optic cable There are two for this situation any network an RPT WF may be used as an interface between wire and fiber a network that uses an AFP1010 or AM2020 a MIB WF may also be used as the interface wire and fiber 1.2 Network Communications Module for Fiber NCM F for requirements and restrictions the use of fiber optic cable See the NOTI Manual Network Version 4.0 and for a discussion of all compatible configurations Installation PN
