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 configura-tion 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. All of the system compo-nents are based on LonWorksŽ (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 LonWorksŽ 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 (ADT-NIS CAB-1 or CHS-4L in ADT-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.
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:
Baud Rate/Switch Position/4 Switch Position 5/Switch Position 6
- 600 Off On On
- 1200 On Off On
- 2400 Off Off On
- 4800 On On Off
- 9600 Off On Off
Parity/Switch Position/2 Switch Position 3
- None On On
- Odd On Off
- Even Off Off
Data Bits/Switch Position 1
- 8 On
- 7 Off
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 the UniMode 400
The RS-232 settings for the panel are Baud Rate – 2400, Data Bits – 7, Stop
Bits – 1, Parity – Even.
NOTE : Panels with software versions prior to 3.00 use RS-232 settings 2400, 7, Even, 1.
NOTES : It is recommended that the installer conform 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 UniMode 400 Control Panel
The NION-400 must be connected to the CPU-400 board of the UniMode 400 panel.
Serial communication wires must be connected to the TB2 connector (EIA 232).
For specific connections, refer to Figure: NION-400/ UniMode 400 Wiring
Diagram. The NION should be mounted within 20ft of the panel with all
connections run in conduit.

Powering the NION from the UniMode 400 Control Panel
The NION should use terminals 3 (+24) and 4 (Common) of the TB2 connector of
the MPS-400 board to get the auxiliary power from the AFP400 panel. This power
source is power limited and non-resettable. For specific connections, refer to
Figure: NION-400/UniMode 400 Wiring Diagram.
Configuring the UniMode 400 Control Panel
The UniMode 400 Control Panel requires no software configuration for
communication with the NION-400. In order to utilize all features available
with the UniMode 400, the UniMode 400 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 : Use only wire for power limited systems. Power limited wire runs use type FPLR, FPLP, FPL or equivalent cabling per NEC 760.
