NAPCO GEMC-NL-MOD User manual

1
GENERAL DESCRIPTION
The NAPCO NetLink™ GEMC-NL-MOD is a device that al-
lows the reporting of alarms over a TCP/IP based (Intranet or
Internet) network. Alarm reporting, previously performed via
Telco only, can now be performed over both a TCP/IP net-
work and/or Telco, or via the TCP/IP network as a backup.
The GEMC-NL-MOD is housed in a separate plastic enclo-
sure, and is connected to the Local Download receptacle for
the Gemini C-Series control panels.
The GEMC-NL-MOD is supported by PCD-Windows Quick-
loader download software version 6.0 or greater. For the pan-
els listed above, the Quickloader software will support
downloading through the Internet or an intranet, as well as the
uploading of logs and other data.
The GEMC-NL-MOD includes a small transient protection de-
vice (named the NL-ULBD) inside its enclosure. In addition,
the GEMC-NL-MOD is one part of a larger system which in-
cludes a software package to allow its configuration before
use (the NL-MODCONFIG) and a rack-mountable Receiver
(the NL-RCV-RMPCUL) to allow the receipt of alarms, status
and supervisory data. A short description of each is provided
below:
NL-MODCONFIG Software (version 2.0 or greater):
NL-MODCONFIG is a software program allowing the con-
figuration of the GEMC-NL-MOD with appropriate informa-
tion (such as the static IP address of the module, static IP
address of the NL-RCV-RMPCUL Receiver, etc.). The NL-
MODCONFIG software is run on a PC (see System Re-
quirements) and connects to the GEMC-NL-MOD via its
network connection. In addition, NL-MODCONFIG allows
the updating of the GEMC-NL-MOD firmware. Note: The
NL-MODCONFIG software and its database should be re-
tained if future access is necessary. For more information,
see WI1243.
Central Station Receiver (NL-RCV-RMPCUL)
The NAPCO Net.Link™ NL-RCV-RMPCUL (Receiver) is a
fully UL compliant central station receiver platform. This
Receiver is rack-mountable in a standard 4U configuration.
The NL-RCV-RMPCUL (Receiver) can supervise each
GEMC-NL-MOD, receive alarms, provide a means of
maintaining accounts and provide a means of displaying
alarms and event history (opening/closing, etc.). For more
information, see the NL-RCV-RMPCUL Installation and
programming manual, WI1491.
Transient Protection (NL-ULBD)
The GEMC-NL-MOD includes electromagnetic protection
and meets direct and indirect ESD requirements for Infor-
mation Technology Equipment (ITE), however, burglary
applications may call for better protection.
The NL-ULBD is a small device which gives added tran-
sient protection and mounts entirely inside the GEMC-NL-
MOD housing. The NL-ULBD protects the GEMC-NL-
MOD from significantly larger transients and surges which
may emanate from the network cable or associated de-
vices. It is connected in series between the Ethernet cable
that provides network access and the RJ45 connector in
the GEMC-NL-MOD. The NL-ULBD is required for UL
compliant installations.

INSTALLATION INSTRUCTIONS
Note: Initial download must be performed locally.
Follow the steps below for existing systems. For new
panel installations, proceed to step 2. After the mount-
ing location and all wire paths are selected, install the
GEMC-NL-MOD as follows:
1. Save the Existing Control Panel Program. To ensure
the panel program is not lost, use PCD-Windows Quick-
loader software (version 6.0 or greater) to upload the
existing program (User, Dealer & Descriptions). If PCD-
Windows is not available, confirm written records of pro-
gramming selections. Note: Program will be lost after
Cold Start (step 3).
2. Perform a Cold Start of the Panel.
a. Press the Dealer Security Code and press A(or
R).
b. Press Buntil "Activate Program? Y/N"ap-
pears, then press D(or U).
c. Press Cto enter Dealer Program Mode.
d. Press 4093D(or U).
Press Ctwice to exit Dealer Program Mode.
3. Download a New Control Panel Program. The PCD-
Windows Quickloader download software can be used
to configure the panel to recognize the GEMC-NL-MOD.
Alternatively, the keypad can be used with Direct Ad-
dress Program Mode to program the panel.
PROGRAM USING PCD-WINDOWS SOFTWARE.
On the Digital Communications menu, there are five
areas that relate to the GEMC-NL-MOD operation.
Configure as follows:
a. Enable TCP/IP Communications. In PCD-
Windows, click the Digital Communications button,
and select the Digital/Dialing Options tab (see image
below). Check "TCP/IP Communications". This fea-
ture informs the control panel that an GEMC-NL-
MOD will be installed in the system, and thus will
make the appropriate adjustments to various
downloading timeouts and to reporting properties.
Click Apply to save.
b. Enable Report to AES-TCP/IP. Select the Central
Station Receivers tab (see image below). For each
telephone number desired, NET-LINK from the pull-
down list (located under the telephone number field)
to enable the panel to report alarms via the GEMC-
NL-MOD accessory. Note: All parameters apply as
they normally would for Telco reporting. For backup
reporting Telephone No. 2 should be enabled. Click
Apply and OK to save.
c. Enable Handshake Local Telemetry (Optional). In
the Digital Communications Options tab (see previ-
ous image), check "Handshake Local Telemetry".
This enables the panel to wait for a transmission ac-
knowledgment from the NL-RCV-RMPCUL Re-
ceiver. (If the acknowledgment fails to occur within
the allotted time, that control panel will generate a
"Telemetry Failure" system trouble). Click Apply to
save. Note: The GEMC-NL-MOD can queue up to
50 alarms and will continuously attempt to transmit
the alarm to the NL-RCV-RMPCUL Receiver.
d. Enable TCP/IP Panel/Site Functions (Optional). In
the same Digital Communications Options tab, check
"TCP/IP Panel/Site Initiated Functions" to enable the
panel to connect via TCP (rather than dialup) for
Auto Event Log Dumps, AutoDL ID, Function 6 and
Site Initiated PCPreset connections. Click Apply to
save.
e. Enable Callback Select and Options (Optional).
Click the Panel Selection button, and select the
Download /Callback Info tab (see image below). The
Callback Select and Options radio buttons for Call-

3
back #1 or #2 will cause PCPreset IP address #1 or
PCPreset IP address #2 to be used, respectively.
Therefore, when "TCP/IP Panel/Site Initiated Func-
tions" (see "d" above) is selected, the GEMC-NL-
MOD will try to connect to a PCPreset computer us-
ing an IP address determined by the Callback # se-
lection. Click OK to save.
Download to Control Panel. Before proceeding, save
the information (File, Save Work). On the toolbar, click
either the Local or Remote Communications buttons.
Note: The TCP/IP Communications button can be se-
lected only after the initial panel download. In addition,
the panel download cannot be performed via TCP/IP
until the GEMC-NL-MOD itself is programmed by the
NL-MODCONFIG software.
In the Select Transfer Operation area, click the
Download to Panel radio button. Check User Program
Area, Dealer Program Area and Description Area.
Click OK to initiate the data transfer to the control panel.
In UL installations, disable remote downloading (UL
does not allow unattended downloading) and after
changing the program, always verify panel operation at
the panel site.
PROGRAM USING THE KEYPAD
Instead of using PCD-Windows Quickloader download
software to program the panel, access the control panel
directly through the keypad as detailed below. See pre-
vious descriptions for each address.
a. Enable "TCP/IP Communications" via address 5328,
option 3 (press 3 on the keypad).
b. Enable "Handshake for Local Telemetry" via address
1718, option 8 (press 8 on the keypad).
c. Enable "TCP/IP Panel/Site Initiated Functions" via
address 5328, option 4 (press 4 on the keypad).
d. For each telephone number desired, enable "Report
to TCP/IP Receiver or AES" via addresses 0526
(option 7), 0551 (option 7) and 0576 (option 7) for
Telco 1, Telco 2 and Telco 3 respectively.
e. Enable "Callback Select Options" via address 1713.
Press either "1" for Callback Telephone Number 1 or
"2" for Callback Telephone Number 2.
4. Mount GEMC-NL-MOD. Remove power to panel. The
GEMC-NL-MOD must be mounted inside the NAPCO
Gemini control panel enclosure. NOTE: For a UL Sup-
plemental Listing, the wire length (GEMC-NL-MOD to
the control panel) must be no more than 20 feet and the
control panel shall reside in the same room as the
GEMC-NL-MOD with no intervening walls or barriers.
Mount using the mounting flanges on both sides of the
GEMC-NL-MOD enclosure using the screws appropri-
ate for the location.
5. GEMC-NL-MOD Jumper. Make sure jumper JP2 is
installed for normal operation. Refer to "Load Factory
Defaults" below for JP2 operation.
6. GEMC-NL-MOD Wiring and Connections. Refer to
the wiring diagram.
a. Insert the LAN Ethernet connector (RJ45 style) into
the receptacle marked "Ethernet" on the GEMC-NL-
MOD circuit board. Insert the other end into the local
network connector.
b. Insert the W1077 harness (supplied) into either the
"RJ25 #1" or "RJ25 #2" of the C-Series control panel
motherboard. Insert the other end into the "LOCAL
DNLD" receptacle on the GEMC-NL-MOD circuit
board.
c. Connect the red flying lead of the W1077 harness
into terminal 1 (+) of the GEMC-NL-MOD. See wir-
ing diagram.
7. Power Up GEMC-NL-MOD. Upon applying power, the
DS1 LED on the GEMC-NL-MOD will turn on and re-
main on during the GEMC-NL-MOD startup sequence
(duration is approximately 15 seconds). The LED will
turn off for up to 20 seconds while the GEMC-NL-MOD
verifies its configuration. The LED will then flash con-
tinuously indicating the unit has not been programmed.
Note: Once the unit has been programmed with an ac-
ceptable program, the DS1 LED will flash for 1 second
and not continuously. After the power up sequence
ends and normal operation begins, the LED will turn on
only when the GEMC-NL-MOD is communicating over
the network.
8. Program the GEMC-NL-MOD with NL-MODCONFIG.
The NL-MODCONFIG software is used to program the
GEMC-NL-MOD. Before using the NL-MODCONFIG
software, obtain a static IP address, subnet mask and
gateway that will be dedicated to network communica-
tion. This information can be obtained from your net-
work administrator. In addition, the Receiver static IP
address must be obtained from the monitoring center.
Install the NL-MODCONFIG software on a PC (see Sys-
tem Requirements on page 2). Then use NL-
MODCONFIG to program the GEMC-NL-MOD.
Use one of two methods:
a. Connect to the GEMC-NL-MOD through the LAN.
b. Use a laptop or a PC connected to a network cross-
over cable (not supplied).
Be sure to have the IP address, subnet mask and gate-
way address. See WI1243 for more information regard-
ing programming with the NL-MODCONFIG software.

Refer to the parallel Input Setup section on page 8 for
more information.
9. Test Installation. Test the system by sending a Digital
Dialer Test report out through the LAN (Ethernet) into
the NL-RCV-RMPCUL Receiver. Note: The GEMC-
NL-MOD will attempt to send check-in signals immedi-
ately after the unit is configured with NL-MODCONFIG
software. Therefore, if the NL-MODCONFIG program-
ming was performed via a crossover cable, then the
control panel will indicate a System Trouble E91 within
two minutes of GEMC-NL-MOD programming.

INPUT SETUP
(IN0 - IN3)
In the NL-MODCONFIG software, use the Optional
Input Setup button (located at the bottom of the NL-
MODCONFIG main screen) to allow the configuration
of four parallel inputs located on the GEMC-NL-MOD
board terminal strip. In the Input Setup dialog, use the
Input Type drop down to select as follows:
•If Active-low selected from the drop-down list, the
input is considered normal if it is above the upper
threshold ("High Limit") and faulted if it is below the
lower threshold ("Low Limit"). An input value be-
tween the lower and upper thresholds maintains the
current state.
•If Active-high is selected from the drop-down list, the
input is considered normal if it is below the lower
threshold ("Low Limit") and faulted if it is above the
upper threshold ("High Limit"). An input value be-
tween the lower and upper thresholds maintains the
current state. A 2.2k EOL resistor is needed. See
diagram below.
•If EOLR is selected from the drop-down list, this en-
ables the 2.2K EOL Resistor. The default input is in a
normal state if the input is between the lower thresh-
old ("Low Limit") and the upper threshold ("High
Limit"). If not between these two thresholds the input
is considered faulted.
If EOLR is selected, the values programmed are
identical to the values used in the panel. For exam-
ple, to install a panic button, connect between the
GEMC-NL-MOD terminals 2 and 6. If button is nor-
mally closed, connect EOL resistor in series. If button
is normally open, then connect EOL resistor in paral-
lel. See diagrams below.
Note: For advanced users, the upper and lower voltage
limits can be programmed into the GEMC-NL-MOD. To
enable these settings to be changed, check Edit Thresh-
olds.
Do NOT check Edit Thresholds for Fire Installa-
tions.
•If Disabled is selected from the drop-down list, the
input is disabled and will not respond to any input
voltage. The Optional Inputs (IN1, IN2 and IN3 on
the GEMC-NL-MOD terminal strip) are configured
with the lower limits set to zero and the upper limits
set to 255. This results in all the Optional Inputs be-
ing normal (i.e. "non-activated") regardless of the ac-
tual input voltage.
Reporting Code
Select a Contact ID Code (E130 =Burglary, E110 =
Fire, etc.) to be displayed by the Receiver or the auto-
mation system.
Note: If E301 A.C. Trouble is selected for input IN3,
and the IN3 input is tripped, reporting for this input will
be delayed 2 hours (if the input opens before the 2 hour
delay ends, the E301 A.C. Trouble report will not be
sent). If E301 A.C. Trouble is selected for the other
inputs (IN0-IN2) the report is sent immediately.
Zone #
Assign a Zone number to the input.
Area #
Assign the input to an area number.
Status Type
Select the status category to be assigned to the zone
when the GEMC-NL-MOD reports a status to the Re-
ceiver. The Receiver Service Application Panel Status
screen displays the attribute selected here, including
Check-In Status.
Note: If Fire Trouble is selected for any input, the
GEMC-NL-MOD will retransmit the reporting code sig-
nal every 24 hours as long the associated input remains
tripped.

NAPCO SECURITY SYSTEMS, INC. (NAPCO) warrants its products
to be free from manufacturing defects in materials and workmanship
for thirty-six months following the date of manufacture. NAPCO will,
within said period, at its option, repair or replace any product failing to
operate correctly without charge to the original purchaser or user.
This warranty shall not apply to any equipment, or any part thereof,
which has been repaired by others, improperly installed, improperly
used, abused, altered, damaged, subjected to acts of God, or on
which any serial numbers have been altered, defaced or removed.
Seller will not be responsible for any dismantling or reinstallation
charges.
THERE ARE NO WARRANTIES, EXPRESS OR IMPLIED, WHICH
EXTEND BEYOND THE DESCRIPTION ON THE FACE HEREOF.
THERE IS NO EXPRESS OR IMPLIED WARRANTY OF
MERCHANTABILITY OR A WARRANTY OF FITNESS FOR A
PARTICULAR PURPOSE. ADDITIONALLY, THIS WARRANTY IS IN
LIEU OF ALL OTHER OBLIGATIONS OR LIABILITIES ON THE
PART OF NAPCO.
Any action for breach of warranty, including but not limited to any
implied warranty of merchantability, must be brought within the six
months following the end of the warranty period. IN NO CASE SHALL
NAPCO BE LIABLE TO ANYONE FOR ANY CONSEQUENTIAL OR
INCIDENTAL DAMAGES FOR BREACH OF THIS OR ANY OTHER
WARRANTY, EXPRESS OR IMPLIED, EVEN IF THE LOSS OR
DAMAGE IS CAUSED BY THE SELLER'S OWN NEGLIGENCE OR
FAULT.
In case of defect, contact the security professional who installed and
maintains your security system. In order to exercise the warranty, the
product must be returned by the security professional, shipping costs
prepaid and insured to NAPCO. After repair or replacement, NAPCO
assumes the cost of returning products under warranty. NAPCO shall
have no obligation under this warranty, or otherwise, if the product
has been repaired by others, improperly installed, improperly used,
abused, altered, damaged, subjected to accident, nuisance, flood, fire
or acts of God, or on which any serial numbers have been altered,
defaced or removed. NAPCO will not be responsible for any
dismantling, reassembly or reinstallation charges.
This warranty contains the entire warranty. It is the sole warranty and
any prior agreements or representations, whether oral or written, are
either merged herein or are expressly cancelled. NAPCO neither
assumes, nor authorizes any other person purporting to act on its
behalf to modify, to change, or to assume for it, any other warranty or
liability concerning its products.
In no event shall NAPCO be liable for an amount in excess of
NAPCO's original selling price of the product, for any loss or damage,
whether direct, indirect, incidental, consequential, or otherwise arising
out of any failure of the product. Seller's warranty, as hereinabove set
forth, shall not be enlarged, diminished or affected by and no
obligation or liability shall arise or grow out of Seller's rendering of
technical advice or service in connection with Buyer's order of the
goods furnished hereunder.
NAPCO RECOMMENDS THAT THE ENTIRE SYSTEM BE
COMPLETELY TESTED WEEKLY.
Warning: Despite frequent testing, and due to, but not limited to, any
or all of the following; criminal tampering, electrical or communications
disruption, it is possible for the system to fail to perform as expected.
NAPCO does not represent that the product/system may not be
compromised or circumvented; or that the product or system will
prevent any personal injury or property loss by burglary, robbery, fire
or otherwise; nor that the product or system will in all cases provide
adequate warning or protection. A properly installed and maintained
alarm may only reduce risk of burglary, robbery, fire or otherwise but it
is not insurance or a guarantee that these events will not occur.
CONSEQUENTLY, SELLER SHALL HAVE NO LIABILITY FOR ANY
PERSONAL INJURY, PROPERTY DAMAGE, OR OTHER LOSS
BASED ON A CLAIM THE PRODUCT FAILED TO GIVE WARNING.
Therefore, the installer should in turn advise the consumer to take any
and all precautions for his or her safety including, but not limited to,
fleeing the premises and calling police or fire department, in order to
mitigate the possibilities of harm and/or damage.
NAPCO is not an insurer of either the property or safety of the user's
family or employees, and limits its liability for any loss or damage
including incidental or consequential damages to NAPCO's original
selling price of the product regardless of the cause of such loss or
damage.
Some states do not allow limitations on how long an implied warranty
lasts or do not allow the exclusion or limitation of incidental or
consequential damages, or differentiate in their treatment of
limitations of liability for ordinary or gross negligence, so the above
limitations or exclusions may not apply to you. This Warranty gives
you specific legal rights and you may also have other rights which
vary from state to state.
