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.
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 |
- All Notifier equipment operates at 2400 baud.
| 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.
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 FS90 Control Panel
The NION-FS90 must be connected to the Serial Printer port of the LH Interface
board installed with the FS90 Control panel. RS-232 settings are: Baud Rate –
9600, Data Bits – 8, Stop Bits – 1, Parity – None.
NOTE: This interface does not provide direct reset, acknowledge or
silence/unsilence control.
Powering the NION
The NION-FS90 can be powered from any power limited source UL or ULC listed,
as appropriate for your area, for use with fire protective signaling units,
providing +24VDC +/- 10% @ 0.080 A.
Device Addressing for the FS90 Control Panel
FS90 device addresses contain a seven digit individual device address.
< Address> AAAAAAA
Example: The panel reports 01.01.110
The NION reports 0101110 to the WKS.
NOTE: Use only wire for power limited systems. Power limited wire runs
use type FPLR, FPLP, FPL or equivalent cabling per NEC 760.
