N-1000-III/IV
Black (Ground) wire of the Keypad. (The Black wire was connected to screw
terminal 12 on the N-1000-II.)
•
Keypads 3 and 4 are no longer available. This means that when 4 readers are
used, only two of them (Readers 1 and 2) can use PINs.
Inputs
•
There is a separate Tamper Input located on TB-9. Tamper Alarms report as
Alarm number 20.
This makes Input 12 (terminal now located on TB-6)
available as a regular alarm input.
•
As described above the default Input Interlocks have changed slightly.
1 and
2 are still the Door Contact Inputs for Doors 1 and 2, but now Inputs 3 and 4
are the Door Contact Inputs for Relays 3 and 4. Also the Egress Inputs for
doors 1-4 are Inputs 5-8 respectively.
•
Each Input can be individually programmed for both Normally Open or
Normally Closed and Supervised or Non-Supervised operation.
There is a special command of the format:
_
W
=pn_input_[SO,SC,NO,NC]<CR>
Where:
input = the number of the input point being set.
SO = Supervised N.O. (Resistor in parallel with switch);
SC = Supervised N.C. (Resistor in series with switch);
NO = Non-supervised N.O.; and
NC = Non-supervised N.C. (default).
•
If an End Of Line Resistor is put on a point, and it is not set up as a supervised
point (using one of the commands above), it will report TROUBLE whenever
the resistance is connected. This should serve as a warning that the point has
not been set up.
•
When a point is programmed as supervised, a generic 2.2K ohm 5% tolerance
resistor is used as the End Of Line resistor.
•
There are several changes to the System inputs.
Alarm 17 Communications failure alarm, but now it reports for either 20 mA
or 485 failures.
Alarm 18 Reserved for future reporting of an Auxiliary Communications
Failure (the RS-232 port.)
Alarm 19 Primary Power Fail alarm as described above.
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.
