NOTIFIER 2C8M NION Board
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 the Network Installation manual, Echelon Local Area
Server manual, or BCI 3 manual as appropriate.
Description of the 2C8M NION
The 2C8M NION (2 Control, 8 Monitor) is a discrete input/output interface used on the network. The NION provides a gateway to the network for equipment and control panels that have dry contacts. It allows conventional panels and equipment to operate on the same network as equipment with an EIA-232 output. The 2C8M NION connects a LonWorks™ FT-10 or fiber network, and discrete monitored devices and conventional control panels. It provides a single, two- way communication channel for discrete inputs and outputs when connected to a control panel. NIONs are specific to the type of network to which they connect (FT-10 or fiber). The transceiver type must be specified and ordered separately when ordering the NION. The 2C8M NION can be powered by any 24VDC power-limited source with battery backup which is UL listed for use with fire protective signaling units. Power must be supervised or placed within 20 ft of the NION with connections run in conduit. The 2C8M NION mounts in an enclosure (NISCAB-1 or CHS-4L in CAB-3/4 series enclosure) with conduit knockouts.
NOTE: Do not use the CHS-4 chassis. For chassis mounting, the NION
requires the CHS-4L. Use of the CHS-4 can cause a circuit short on the NION
motherboard with unpredictable results.
Installation Description
The NION 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).
NOTE: Use only wire for power limited systems. Power limited wire runs use type FPLR, FPLP, FPL or equivalent cabling per NEC 760.
Mounting
The NION is designed to be installed on a wall within 20 feet of the monitored
equipment 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.
NOTE: When using the DFXC transceiver with the 2C8M NION, be sure to use the longer standoffs and header adapter provided with the DFXC transceiver.
NION Power Requirements
The 2C8M NION requires 24 VDC @ 0.10 A nominal and battery backup in
accordance with local code requirements. It can be powered by any power
limited 24 VDC source which is UL or ULC listed, as appropriate for your area,
for use with fire protective signaling units.
NOTE: 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.
NION-2C8M LEDs
Four LEDs on the front panel of the 2C8M NION provide information about module operation. The table below explains the possible conditions.
NOTE: Refer to Figure 1: 2C8M NION Board Layout for the position of each
of the LEDs listed below.
I/O Configuration and Connections
Inputs
The NION accepts eight normally open or normally closed dry contact inputs.
Each normally open input is monitored by an end-of-line resistor. These inputs
are wired to a 16-point plug-in terminal strip in the following pattern
:
The PCB is labeled, and the terminals are numbered for convenience. Inputs are rated for 18V nominal, 1.8mA maximum current and 2,000 ohm maximum resistance. Each normally open input circuit requires a 10k EOL resistor installed in parallel with the contact.
NOTE: Normally closed inputs are not supervised and cannot be used for fire applications.
Select each input style (NO or NC) by setting jumpers JP4 through JP11to the desired settings using the following diagram: Each input also has a related pair of LEDs, a red LED to indicate an alarm state (short) and a yellow LED to indicate a trouble state (open).
Outputs
The 2C8M NION provides two SPDT relay outputs. The relays are rated at 5A @
30VDC. They can be wired for normally open or normally closed operation. All
rated loads are resistive. Inductive and tungsten loads will be lower. For
special applications, consult with a NOTIFIER applications engineer
.
NOTE: Input and output lines should not exceed 2000ft.
General Configuration
In order to utilize all features available with the 2C8M NION, the 2C8M
Scheduling Plug-In utility must be configured at the system workstations.
General Plug-In setup information can be found in the Workstation manual.
