Product Installation Document
This document covers the procedures and specifications for installing the above listed unit and when appropriate, information regarding configuration on the monitored device. For more detailed configuration and operation information, refer to Network Installation Manual, Echelon Local Area Server Manual, or BCI 3 Manual as appropriate.

Description of the Serial NION-232B

The Serial NION-232B (Network Input Output Node) is the EIA-232 interface used with the network. All of the system components are based on LonWorks™ (Local Operating Network) technologies. The Serial NION-232B provides transparent or interpreted communications between the workstation and control panels. Unless otherwise noted, full control capabilities are available for each interface. Check specific connections for details. The NION connects a LonWorks™ FT-10 or FO-10 network, and the RS-232 port of control panels. It provides a single, two-way communication channel for RS-232 serial data when connected to a control panel. NIONs are specific to the type of network to which they connect (FT-10 or FO-10). The transceiver type must be specified and ordered separately when ordering the NION. The NION can be powered by any 24VDC power limited source with battery backup which is UL listed for use with fire protective signaling units. The NION mounts in an enclosure (NIS CAB-1 or CHS- 4L in CAB-3 series enclosure) with conduit knockout.

Site Requirements
The NION-232B can be installed in the following environmental conditions:

  • Temperature range of 0ºC to 49ºC (32°F – 120°F).
  • 93% humidity non-condensing at 30ºC (86°F).

Mounting
The NION-232B is designed to be installed on a wall within 20 feet of the control panel in the same room. The type of hardware used is at the discretion of the installer, but must be in accordance with local code requirements .NOTIFIER-NION-232B-600-Fire-Alarm-Board-1

Serial Communication Description
The baud rate, parity and data bits of the NION-232B must be equal to those of the RS-232 serial port of the control panel. The NION-232B comes from the factory preset for the application it was ordered to fill. These settings are made on switch S2.
If it becomes necessary to change any of these settings use the chart below :NOTIFIER-NION-232B-600-Fire-Alarm-Board-2

Note: If the device connected to the NION calls for 9 data bits then the NION must be set to 8 data bits with either Even or Odd parity.

NION Power Requirements
The NION-232B requires 24 VDC @ 0.080 A nominal and battery backup in accordance with local code requirements. It can be powered by any power limited source with battery backup which is UL listed for use with fire protective signaling units.

Serial Communications with Notifier Products

The RS-232 settings for most Notifier panel are: Baud Rate – 2400, Data Bits – 7, Stop Bits – 1, Parity – Even The exceptions to this are the AFP 400 panel which uses Baud Rate – 2400, Data Bits – 8, Stop Bits – 1 and Parity – None. These settings are valid starting with AFP 400 software version 3.00. Another exception is the AFC 600 which uses Baud Rate – 9600, Data Bits – 8, Stop Bits – 1, and Parity – None.

NOTE: It is recommended that the installer conforms to local code requirements when installing all wiring. All power connections must be non- resettable. Refer to the current Notifier catalog for specific part numbers and ordering information for each NION. Always remove power from the NION before making any changes to switch settings and removing or installing option modules, SMX network modules and software upgrade chips or damage may result. Always observe ESD protection procedures.

Serial Connections with the AFC-600 Control Panel
The NION-600 must be connected to the CPU-400 board of the AFC-600 panel. Serial communication wires must be connected to the TB2 connector (EIA 232). For specific connections, refer to Figure: NION-600/AFC- 600 Wiring Diagram. The NION should be mounted within 20ft of the panel with all connections run in conduit.NOTIFIER-NION-232B-600-Fire-Alarm-Board-3

Powering the NION from the AFC-600 Control Panel
The NION should use terminals 3 (+24) and 4 (Common) of the TB2 connector of the MPS-600 board to get the auxiliary power from the AFC-600 panel. This power source is power limited and non-resettable. For specific connections, refer to Figure: NION-400/AFC-600 Wiring Diagram.

Configuring the AFC-600 Control Panel
For all panel software versions the AFC-600 Control Panel requires no software configuration for communication with the NION-600. In order to utilize all features available with the AFC-600, the AFC-600 Plug-In utility must be configured at the system workstations. Each Plug-In is described in detail in the Product Installation Description shipped with each NION. General Plug-In setup information can be found in the workstation manual.

NOTE: Be sure that if you use AFC-600 plugins that you associate them with AFC-600 NIONS.
NOTE: Use only wire for power limited systems. Power limited wire runs use type FPLR, FPLP, FPL or equivalent cabling per NEC 760.
