N-1000-III/IV
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).
