Preface
The N-1000-III/IV Installation Manual provides all information necessary for
installation of N-1000-III, N-1000-III-X, N-1000-IV, and N-1000-IV-X control panels.
All of the N-1000-III/IV versions have both the 20 mA and 485 multi-drop commu-
nications interfaces.
The N-1000-III/IV can be used in existing N-1000-II/N-800 systems provided the
existing panels have version 8.0 or higher firmware.
Note: When the N-1000-II/N-800 is configured for 485 (N-485-API-x), the
firmware version must match the 485 version in the N-1000-III/IV.
The following table identifies the different features of each version of the N-1000
panel:
Version* CardReaders MatrixKeypads Alarm Inputs** Relay Outputs Cards*** Buffers***

N-1000-IV-X 4 2 16 8 25,000 6,600
* A version with removable wiring terminal strips is available for each model and is
designated by an Rafter the version number.
**Two system alarms are independent of the sixteen zone inputs. Matrix keypads do
not use any of the 16 alarm inputs.

UL Note
The N-1000-III/IV panel’s alarm point monitoring only monitors the door position
(UL294). It is not intended as a proprietary burglar alarm (UL1094).
The control panel was UL294 tested as a stand alone unit only.
The N-485-HUB-2 was not investigated by UL.
The N-1000-III/IV was UL294 tested using the following card readers:
• Model 30387 (CR-1) Wiegand swipe reader.
• Model 5365BGP00 (PR-MINI-PROX) proximity reader.
• Model 5355AGN00 (PR-P-PRO) proximity reader.
The N-1000-III/IV was UL294 tested using the Basler Electric transformer part
number BE11625CAA-0042 (X-4).

New and Improved Features of the N-1000-III/IV
The N-1000-III/IV series panels have both a number of improvements and some
unique features as compared to the N-1000-II control panels. Some of these
features are highlighted below. For a more detailed description refer to Appendix B
of this manual.
• Four layer PWB and other improvements provide greater electrical noise immu-
nity.
• High efficiency switching regulators result in reduced heat generation and
extended backup battery operation.
• A Four Reader Board allows the N-1000-IV panel to support a total of four
readers. (See Section 4-3 for details.) When this board is present all four
readers attach to it via its removable terminal strips. A Reader Function
Test is available on the Four Reader Board by shorting a pair of jumper prongs
labeled TEST. This will cause the board to generate a simulated card read from
each of the four readers.
• An improved canister has more knockouts, a larger battery bracket and im-
proved wiring space, since the board is centered in the enclosure. (The old
enclosure can be field retrofitted for the new board.)
• The processor speed is substantially faster than the standard N-1000-II, increas-
ing the speed of internal processing. At the same time, communications output
is the same as the N-1000-II panels so they can be used in the same loop.
• An additional Terminal Block (TB9) has been added in the upper left quadrant
of the board. This terminal block has an Earth Ground connection; a battery
plus and minus (in addition to the soldered-in battery wires); AC connections 1
and 2 (there are no spade lugs for AC or battery); the Tamper and External
Power Status inputs with common posts; and a place to tie the RS-485 shields.
• The N-1000-III/IV firmware (version 08.01.29 or later) has a built-in test
capability that can be used to check the functioning of most of the circuit
board’s hardware. This feature is detailed in Appendix C: Trouble Shooting.
• There are both RS-485 and RS-232 communications ports in addition to the 20
milliamp port. The RS-485 port is selected by a change of Jumper 1 in lieu of
the 20 milliamp. The RS-232 port can be used in addition to or instead of the
other ports.
• A 16.5 volt AC power source is now required, allowing the charging of a 12 volt
battery for back-up as well as the supply of 12 volt reader and PIR egress power
from the N-1000-III/IV.
• A 12 volt, 500 mA output is available for powering 12 volt readers or PIR
egress detectors. Connections for this are at TB9 terminals 7 (+) and
8 (Common).

viii N-1000-III/IV
• Detection of a primary power failure by either the internal sensor or the
input from the relay on the external supply will generate an Alarm 19 not
Alarm 8. Alarm Point 8 is now available for use as a standard alarm point
• Automatically resetting solid state fuses are used.
• The Green Low-V OK LED will go off to indicate low 12 Volt battery (indicator
turns off at approximately 10.1 volts, the panel shuts down at approximately
9.9 volts) or disconnected RAM back-up (JP9 removed).
• A special set of connectors for the AEP-3 Relay Expansion board is provided. J1
is a connector for the present AEP-3 Board design. J2 is a double connector and
will be used for a future development.
• There are screw terminals for the reader cable shield connections. These are
nearer to where the wires come in, eliminating the need to run the shield wire
around the board.
• The terminals on Terminal Block 8 are used exclusively for 11 wire Keypads.
This makes all regular inputs available even when a keypad is used. The K
option is no longer needed. The P option must still be entered for use with
PINs. Screw Terminal 4 is used for the Black (Ground) wire of the Keypad.
• There is a separate Tamper Input located on TB9. This makes Input 12 (termi-
nal now located on TB6) available as a regular alarm input.
• Each input can be individually programmed for both Normally Open or Normally
Closed and Supervised or Non-Supervised operation.
• There are several changes to the System inputs.
Alarm 17 Communications status alarm, but now it reports for either 20 mA
or 485 failures.
Alarm 18 Reserved for future reporting of an Auxiliary Communications Status
(the RS-232 port.)
Alarm 19 Primary Power Fail alarm.
Alarm 20 Tamper alarm (with special terminal connections on Terminal
Block 9).
Alarm 21 Input Ground Fault alarm. If the input is shorted to Earth Ground
this alarm will be generated. (Some fault conditions may generate
an ALARM rather than TROUBLE from the point, but no ground fault
will be interpreted as NORMAL.)
Alarm 22 Reserved for future use.
Alarm 23 Indicates an external 5 volt reader power short circuit.
Alarm 99 Generated at restart either due to the Push Button or the watch dog
timer. (This alarm cannot be stored in the history buffer.) A 99
trouble is communicated on a cold boot-up reset when the RAM
memory is being initialized.
•Relays are heavy duty inductive load rated. They have a maximum load rating
of 30 VDC, 5 A Resistive, 2 A Inductive. They also have circuitry which is less
susceptible to electrical switching noise.

INTRODUCTION
Section 1: Access Control
Access control is computerized control over entry to any area that can be secured
with a lock and key. Entry is only allowed to authorized people at authorized times.
Control of who is allowed to come and go is easily maintained.
The weakness of a lock and key security system is the common key. The key is a
readily duplicated piece of metal that gives anyone who holds it access to an area.
The risk of lost or stolen keys, with the expense of changing locks, is a costly
problem. Access control is an effective and affordable solution to this problem.
With access control, each person receives a card or keycode which restricts access
to authorized areas at authorized times. A small, programmable control panel
allows or denies access. If a card is lost or stolen, or if a keycode is no longer
secure, the control panel can be reprogrammed quickly and easily.
An additional benefit of access control is report capability. The system provides
reports of all card/keycode activity, including whether access was granted or
denied, and why. A permanent record of all entries to an area can be maintained.

Section 2: System Overview
2-1: N-1000-III/IV
The N-1000-III/IV control panels are the decision-making units in the access
control system. Each control panel contains a central processing unit (CPU)and
memory for local control capability. Control panel database information is
programmed from a central programming device (computer, printer/programmer
or data terminal). The panels then operate independently from the
programming device. In this distributed database system, the programming
device need not be on-line for system operation.
The control panels interface to the programming device via the C-100-A1
20 mA Current Loop Converter or via the 485 multi-drop interfaces
(N-485-PCI-2 or N-485-HUB-2). A single communications loop supports up to 63
uniquely addressed control panels if the 20 mA loop is utilized or 31 panels for
485 communications. A typical 20 mA communications loop configuration is shown
in Figure 2-1, while Figure 2-2 illustrates a typical 485 multi-drop
configuration.
The N-1000-III control panel provides 16 points for alarm monitoring and four
output control relays. The N-1000-III-X control panel includes four additional
relays (providing a total of eight) and has expanded database/buffer memory
capacity. The N-1000-IV version has four rather than two card readers and four
output control relays. The N-1000-IV-X control panel includes four additional relays
(providing a total of eight) with expanded database/buffer memory capacity. The

N-1000-III-X is shown in Figure 2-3 with enclosure and battery. Figure2-4 shows
the N-1000-IV-X with Four Reader Board, battery and enclosure.
The minimum configuration for the N-1000-III/IV includes the control panel,
power transformer, reader and communication converter.
Control panels can operate in a buffered mode in which system transactions are
stored in transaction buffer memory at the panels rather than transmitted to the
programming device. Every transaction (input point change of state, code use) uses
one location in buffer memory. The buffered information can later be transmitted
tothe programming device.
The N-1000-III/IV firmware (version 08.01.29 or later) has a built-in test capability
that can be used to check the functioning of most of the circuit board’s hardware.
Refer to Appendix C: Troubling Shooting for details.
2-2: Programming Devices
N-1000-III/IV control panels in a communications loop are programmed with a
personalcomputer, printer/programmer ordata terminal.
When using a personal computer as the system programming device, the PC
software serves as a database manager for the N-1000-III/IV control panels.
Information is entered into the PC databases and then downloaded to the
control panels. During the download procedure, the PC software converts the
database information at the disk level to a series of command strings from the
N-1000 instruction set. The commands are then sent to the appropriate control
panels. The panels then operate independently from the computer. The advan-
tages of using a computer as the system programming device include ease of
programming and operation, permanent disk storage of all database
information and extensive report options.
Figure 2-2. Typical 485-Multidrop Configuration. The N-1000-III/IV can be used in
existing N-1000-II/N-800 systems provided the existing panels have version 8.0 or higher
firmware. When the N-1000-II/N-800 is configured for 485 (N-485-API-2) as in this example, the
firmware version must match the 485 version in the N-1000-III/IV.

Whenusing a printer/programmer or data terminal as the system programming
device, all command strings are sent manually to the control panels by the operator.
Printer/programmer and data terminal programming provide no safeguard
against lost database memory at the panel level.
2-3: C-100-A1 Converter
The C-100-A1 Converter serves as the interface between the programming
device and the N-1000 control panels. The C-100-A1 allows the programming
device, using RS-232 port, to communicate with the control panels in a 20 mA
current loop. The C-100-A1 can be configured for use as a C-100-C, C-100-T or
C-100-M, determined by the position of six DIP switches on the RS-232
connector. These configurations are used as follows:
• computer to local control panels C-100-C
• printer/programmer to local control panels C-100-T
• computer to remote control panels via modem C-100-M
Refer to the C-100-A1 Manual for further details.
2-4: N-485-PCI-2 or HUB-2
The N-485-PCI-2 is used to interface between a PC’s RS-232 port and the 485
multi-drop communications bus. The N-485-HUB-2 is used to interface between a
modem’s RS-232 port and the 485 multi-drop bus. Only the “-2” versions of these
products will function with the N-1000-III/IV.
2-5: PROM Versions
The N-1000-III/IV PROM (Programmable Read Only Memory) chips provide
permanent storage for the program and control logic information necessary to
coordinate and drive the system hardware. The PROM chip is also referred to
as the control panel’s FIRMWARE.
The PROM version in use determines the commands and programming features
available for use with the control panel. Operations such as alarm point programming,
site code checking, card/ keycode capacity, transaction buffer capacity, Visitor
and Limited Use status cards and local anti-passback are all functions of the
PROM version in use. Specific command string syntax and the availability of
advanced programming commands are also dependent upon the PROM version.
Refer to the command summary in Appendix A of this manual. Or contact NCI
for additional information on PROM versions.

Input points are provided which can be configured for either normally open or
normallyclosedandeither3statesupervisedorunsupervised.Separatenon-supervised
inputs are provided for an optional external primary power fail indication and the
standardenclosure tamper switch.
Relay Output Points:
Four double pole, double throw (DPDT) relay contacts with both normally-open
and normally-closed sides, rated for 30 VDC 2 amp inductive loads. The N-1000-III/IV-X
controllers provide four additional relays (eight total). These relays can also be
utilized in dry circuit applications (e.g. , mechanical shunts, data interruptions,
etc.). NOTE: once the relay pole has been used on an inductive load (door
strikes, magnetic locks, etc.) it cannot be used in low current dry circuit applications.
Northern recommends using the “A” pole of the relays for inductive loads and
the “B” pole for dry circuit (logic) loads.

INSTALLATION
Section 4: Panel Layout
The N-1000-III-X has nine screw-down terminal blocks. Each terminal block, in
turn, has 12 individual terminal positions, described in the following sections.
Figure 4-1 shows the panel with its printed template. The N-1000-IV-X has an
additional board in place of TB5 (see Figure 4-2) with four removable wiring
terminal blocks for connection to four readers. Complete terminal block details
follow.

4-1: Four Reader Board (N-1000-IV only)
The N-1000-IV supports up to four card readers. All four readers attach to the
panel via a special Four Reader Board mounted in the lower right quadrant of the
N-1000-IV panel (see Figure 4-2). The wiring terminals are removable and
interchangeable. The regular reader terminals on the main board are not used.
This board is connected to the main panel by connector P3, located directly
above the bottom center of the N-1000 panel.
Typical wire color terminations are illustrated in Figure 4-3. Refer to the reader
installation technical bulletin (included with the reader) for the most recent
color terminations.

A special, programmable chip, called a PIC chip, controls the Four Reader Board.
The PIC chip is labeled with a version number similar to the label on the main
panel's PROM chips.
The Four Reader Board has its own Status LED that flashes when it is powered
and running. When a card is read the Status LED gives a long flash. When the
LED stays on for an extended period of time it indicates that the board has reset
due to an error or power supply problem.
A pair of jumper prongs located on the Four Reader Board allows a reader
function test. Shorting these prongs (labeled TEST) will cause the board to
generate a simulated card read (with the PIC firmware version ) from each of
the four readers.
Figure 4-3. Four Reader Board. On the N-1000-IV the Four Reader Board replaces
Terminal Block 5 and provides connections for up to four readers.
