LINKS1000 GLOSSARY OF TERMS
The following is a description of various terms used with regards to cellular technology.
Electronic Serial Number (ESN)
The ESN is the unique serial number of a cellular phone. It is used by the cellular network to track calls and
increment billing. The ESN is stored at the time of manufacture and cannot be reprogrammed. This number,
in either hexadecimal or decimal, must be loaded into the database of the cellular carrier before service can
begin.
Cellular Phone Number and Area Code
A 10 digit number (3 digit area code and 7 digit directory number ) identifying the cellular telephone. Do not
enter the phone number of the central monitoring station as the cellular phone number when programming
the LINKS1000.
Initial Paging Channel
A three digit number that specifies which ‘Side’ carrier you have contracted for service. Each cellular service
area only has two sides, A or B. The initial paging channel for Side A is ‘333’ and for Side B is ‘334’.
System ID
Also called the Home Access ID, this 5 digit number identifies the customer's predefined ‘Home System’. This
number refers to a geographic area and is used by the cellular carrier to determine if the unit is ‘Home’ or in
‘Roam’.
Access Overload Class
This is the number that specifies the level of priority of the cellular call. There is no correlation between this
number and the level of cellular service unless there is a network emergency.
Group Identification Mark
This number is factory programmed and specifies how many bits of the System ID are compared when
processing signals. The Group Mark ID for LINKS1000 is set at 10. This number will make the LINKS1000
compatible with all North American networks.
Preferred System Mark
This number is determined by the Initial Paging Channel and refers to which system, A or B, is scanned for
first.
Roam/Roaming
Using cellular service outside of one ‘Home’ area. Usage charges are higher when Roaming.

INTRODUCING THE
The LINKS1000 Cellular Alarm Transmitter enhances the protection provided by a security system by
providing a reliable backup to the control panel’s normal telephone communications with the monitoring
station. The LINKS1000 works with the DSC and Sur-Gard Security Control Panels described in the
Specifications below.
If the control panel is unable to complete an alarm transmission through the normal telephone line, due to any
line problems, the LINKS1000 will be activated and will transmit the alarm communication over the cellular
network. The LINKS1000 works automatically.
The LINKS1000 has been designed for simple and straightforward installation. Wiring connections are made
directlybetweentheLINKSunitand the securitycontrol panel.The DSCand Sur-GardSecurityControlPanels
require only minor changes in their Programming Sections

HOW THE LINKS1000 WORKS
Cellular Communications
All cellular telephones, including the LINKS1000, must ‘register’ with the cellular network. ‘Registration’ is
simply a handshake, sending ESN and Telephone number, between the cellular switching station and the
cellular telephone. This is done upon power up of the LINKS1000 and randomly once a day. If the phone does
not register the network will not complete a call. Tower signal strength, also called RSSI (receive signal
strength indication) is updated approximately every 4-5 seconds. RSSI is indicated as a go/no go visible via
the RSSI LEDs (L3, L4, L5, L6).
Sending an alarm
Before dialing the central station, all DSC alarm controls perform a telephone ‘line-test’. This is done via the
control unit using a series of off-hook and on-hook transitions to verify dial-tone. This takes 30 seconds.
The control panel ‘line-test’ feature will only determine a telephone line is inoperative when it is attempting to
sendan alarm.WithaLINKS1000 connected,thecontrolpanel willsendthe central stationtelephonenumber,
in a digital format, from the PGM output of the control panel to the PGMIn input of the LINKS1000. The
LINKS1000 then accesses the cellular telephone network and begins dialing. Once a suitable channel is
established the LINKS1000 switches an onboard relay and establishes a connection between the TIP and
RING terminals on the control panel and the T1 and R1 terminals on the LINKS1000.
With cellular communications now open to the central station receiver, the panel will detect ‘handshake’. The
alarm is sent. If the message is received, ‘kiss-off’ is sent, just as if it were communicating over a standard
telephone line. Once the panel has completed the transmission, the control panel ‘hangs up’. The LINKS1000
then detects the loss of current across T1 and R1 and sends the END key to the cellular network.
Telephone Line Monitor
TheTelephone LineMonitorisa separatefeatureintegral toDSCor Sur-gard controlpanelsPC1575, PC1580
and higher. The TLM looks for a 30 second loss of telco line voltage. With a LINKS1000 connected and TLM
signaling enabled, a service outage would trigger the panel to begin dialing though the LINKS1000. Dialing
will begin after the TLM time-out and ‘line-test’ are complete. This should take 1 minute.
Trouble supervision
Trouble supervision of the LINKS1000 is provided in one of two ways:
When Jumper J1 is ON (shorted), a general system trouble indication is used at the LINKS1000 SYS TBL
terminal. All trouble indications will trigger this output to the control panel.
When Jumper J1 is OFF (removed), there are three separate trouble outputs: AC TBL, Bat TBL, and the
LINKS1000 SYS TBL. The AC TBL terminal and Bat TBL terminals are each used to indicate their respective
troubles. The LINKS1000 SYS TBL will activate for all other troubles. These outputs are connected from the
LINKS1000 terminals to separate zones on the control panel. The zone(s) should be programmed as 24-hour
silent except on the PC1575, PC1580, PC4010, PC4020, PC4020KT, PC5010, PC5015, PC1555, PC1565,
PC5008, PC580 and PC585 where a zone (or zones) is designated for LINKS1000 supervisory. Under normal
conditions, the TBL outputs of the LINKS1000 are “open”. When one or more of the six monitored trouble
conditions are present, and the corresponding time-out has expired, the respective output will be pulled to
ground. The connection from the LINKS1000 TBL output to the control panel zone, forces the zone to ground.
The panel now has an alarm it must send and the dialing sequence begins. Typically, trouble signals are sent
via the telco line. If the telephone line is not operational, the panel will send the signal via the LINKS1000 and
the cellular network.
This configuration is required on UL Listed systems.

5
Downloading
Downloading an alarm control via the LINKS1000 requires connecting the RING terminal on the LINKS1000
to the proper terminal on the control panel (see instructions). Then, from the downloading computer, simply
dial the cellular telephone number of the LINKS1000. The LINKS detects an incoming call and pulls the RING
terminal to 12 VDC. This instructs the alarm control to answer, the panel then provides continuity across TIP
and RING. The LINKS detects current flow and connects the LINKS T1 and R1 and the panel TIP and RING.
Upon completion of downloading, the LINKS1000 will ‘hang up’. The LINKS1000 will automatically disconnect
any call after a 20 minute duration.
Emergency Phone Number
This number is programmed into the LINKS1000 and will be dialed when the AUX IN terminal is shorted to
ground. To program the number, enter the emergency phone number into the LINKS1000, exactly as it would
be dialed on a cellular phone. To use this feature, place an ordinary handset in parallel with the panel on the
LINKS1000 T-1, R-1 terminals and connect a normally open pushbutton across the AUX IN and Ground
terminals.
NOTE
: This input is a 24-hour, silent terminal and the Panic phone call will be connected through the cellular
network.
Powering the LINKS1000 from a DC Source
The LINKS1000 (v3.0 and higher) has the capability to be powered only by a DC source. This could be useful
in such applications as: large recreational vehicles, motor homes, transport trucks, large boats, etc. In these
cases, the main power source is the vehicle’s battery and DC electrical system with no true AC source for the
control panel or LINKS1000 to draw power from.
To use the LINKS1000 with only a DC source, short jumper J2 and leave in place. Connect all wiring for the
LINKS1000 except for the power circuit. Once all connections are made, connect the vehicle’s DC source to
the battery leads of the LINKS1000 (observing correct polarity) and test the control panel and LINKS1000
according to the “Testing the System” sections of their respective manuals.
NOTE
: If the LINKS1000 is being used for such an application, the central station should be notified when the
vehicle is being serviced to avoid possible false alarms.
NOTE
: The LINKS1000, control panel and DC source should be in a physically secure location to avoid
possible tampering.
WARNING: Though the Links1000 product is capable of roaming, this is fully dependant on the service
provider.
This configuration should not be used on UL Listed systems.

ArrangingforCellularService
In order for the LINKS1000 to communicate via the cellular telephone network, an account must be set up with
a cellular network operator. The ‘account’ is simply a matter of establishing the billing information for the
cellular service. In return, the cellular carrier will provide you with the
cellular telephone number.
Cellular
service may vary in price and coverage. Check with your cellular service provider for area coverage maps
and service charges.
Any cellular telephone service provider may be used as the LINKS1000 is compatible with all AMPS type
cellular telephone networks. There are a maximum of two separate network operators in a given market. They
are called non-wireline carriers (A-Side) and wireline carriers (B-Side). Choose the carrier and rate plan that
best fits the application.
DSC is not a cellular service provider, however the LINKS1000 is licensed to use the ‘HELPTEL’ cellular
service rate offered by LINDSAY Communications of Loeminster, Massachusetts. This coverage is virtually
nation wide, using exclusively A-side carriers, and offers service rates that are designed for cellular
applications requiring minimal air time. (In most applications the LINKS1000 is configured to activate only
when the alarm is set and the protected premises experiences an unanticipated loss of dial tone.) LINDSAY
Communications can be reached at 1-800-878-9898. For answers to any other questions concerning cellular
activation call 1-888-623-7873.
Note: When using LINDSAY Communication for cellular service, pay close attention to the PREAMBLE
Section when programming the control panel.
Using the LINKS1000 Programmer
The LINKS1000 Programmer is used to enter the required cellular network parameters into the LINKS1000.
If the parameters are not entered correctly, the LINKS1000 will not operate.
AC power must be applied to the LINKS1000 in order to program any data.
Connect the modular connector of the Programmer to the modular jack on the LINKS1000. Press any key to
activate the Programmer. The LCD screen will light up.
Note:
If the screen does not light up, check to see if 4 AA batteries were correctly installed in the back of
the Programmer.
The LINKS1000 Programmer is menu driven (see Table 1 for a list of menu messages):
• use ‘up’ and ‘down’ arrows to scroll through the various menu fields
• when the desired field is displayed, use the [✱✱
✱✱
✱] key to select it
• or use the numbers shown in parentheses to go directly to the desired menu or item
• use the [#] key to enter data and exit the section.
Before a cellular service provider will give the Cellular Phone parameters, you must first give the LINKS1000
Electronic Serial Number (ESN). The ESN is found on the LINKS itself (in hexadecimal), or can be read via the
Programmer (in hexadecimal).
If the ESN was not found on the LINKS1000, scroll to the “Read LINKS” menu. Select the ESN and the LCD
will display the ESN in hexadecimal form.
Record the ESN here: l_____l_____l- l_____l_____l_____l_____l_____l_____l

MountingtheCabinet
It is important to mount the LINKS1000 as close to the DSC / Sur-gard alarm control panel as possible
.
3 feet is the recommended maximum distance between the two devices. If the devices are mounted in an
under-over arrangement, always mount the LINKS1000 on top. It is recommended that all wiring between the
control panel and the LINKS1000 be in a tamper and attack-resistant conduit.
Keep in mind the LINKS1000 antenna must be mounted above ground level. If necessary, Antenna
Extension Kits are available from your distributor. Remember cellular likes height. The antenna should be
installed in a physically secured location to avoid tampering.
As much as reasonably possible the LINKS1000 should not be located near sources of interference. These sources
includeEMI generatedby televisions orheavy electricmotorssuch asthosefound inheating or airconditioning units.
Removeprinted circuitboard andwallmounting hardwarefrom cardboard retainerinside cabinet.Beforeattaching
the cabinet to the wall, press the white nylon mounting studs through the holes in the back of the cabinet.
Mounting the Antenna
NOTE:
An antenna should always be connected to the LINKS1000 whenever it is operated. The unit will not
function properly if an antenna is not installed.
Before attaching the antenna, first secure the TNC connector and cable attached to the LINKS unit in the hole
in the top of the cabinet using the hardware provided. Ensure the star washers make solid electrical contact
with the metal cabinet; refer to the illustrations below.
The antenna should be mounted as high above ground level as possible while at the same time taking care not
to place the antenna under a Radio Frequency shield of any kind. I.E. do not mount the antenna directly beneath
ametal roofingoverhang. Cellularworksbest wheninan unobstructed “lineofsight” tothecellular antennasite.

Do not connect the transformer or battery until all other wiring is complete. Use a
16.5 VAC transformer with a minimum 40 VA rating to supply AC power to the LINKS1000. Do not connect the
transformer to an outlet that is controlled by a switch.
UL Listed systems should employ the ATC-Frost PIN
FTC3716 transformer.
Note: All terminals are power limited except for the battery leads. All power limited wiring shall be
installed using FPL, FPLR, FPLP or permitted substitute cable.”
INSTALLATION

GroundConnection
ConnecttheLINKS“AUX-GND”terminaltothecontrolpanel“GND”terminal.AUX-orKEYPADBLACKandZONE
COMMON are also good ground connections.
A good ground connection is essential for proper operation.
Connect a ground cable from the Cabinet Ground connection to an earth ground, such as a copper cold water
pipe, by the shortest and most direct route. Ensure that the cold water pipe connection provides path to ground.
Do not make the ground connection to a plastic cold water pipe!
Tamper Terminal
The “TMP” terminal on the LINKS1000 is provided for a cabinet tamper switch. If a tamper switch is not used,
then a wire jumper must be connected between the “TMP” and “GND” terminals.
Supervision of LINKS-to-Panel Connection
To make use of the cable tamper alarm simply connect an end-of-line resistor, of the value indicated on the
hook-up diagram, across the GND terminal and the LINKS SYS TBL terminal. If the cable between the LINKS
and the control panel is cut, a fault will be presented to the LINKS1000 supervisory zone.
NOTE:
Resistor must be installed in LINKS cabinet.
LINKS SYS TBL Terminal
When jumper J1 is shorted, this terminal is used to report all troubles to the attached control panel, including
the AC and Battery troubles. The AC TBL and BAT TBL terminals will be disabled when J1 is shorted.
When jumper J1 is open, the AC TBL and BAT TBL will be reported at their respective terminals. All other
troubles will be reported through the LINKS SYS TBL terminal.
The LINKS SYS TBL terminal will switch to ground whenever a trouble condition is present on the LINKS unit. The
terminalwillremainswitchedto ground foraslongasatroubleconditionexists.This feature isused toreportLINKS
trouble conditions through the control panel via a zone programmed for LINKS Supervision (see programming
guideforinstructions).Also,whena resistor isconnected acrossGND ofthe LINKSandtheSYSTBLoftheLINKS,
then connected to the designated LINKS supervision zone, the control panel will report an open in the connection
between the LINKS and the control panel (see instructions for correct resistor value).
When using Normally Closed Loops, connect a DSC Model RM-1 Relay to the control panel and the LINKS
as described below. The Alarm and Reporting Codes programmed for the zone connected to the yellow lead
of the RM-1 will be used to report a general trouble and restore on the LINKS. Note that the PC5010, PC5015,
PC1555, PC1565, PC5008, PC580, PC585, PC4010, PC4020 and PC4020KT always use an end-of-line
resistor regardless of how zone supervision is programmed.

LINKS RING Terminal Allows Panel to be Downloaded via LINKS
Whenever the LINKS phone number is called, the RING terminal will activate. This feature may be used to
make the control panel answer an incoming call via the cellular telephone network.
PC1500 and PC1550
Connect the LINKS RING terminal to the control panel’s Zone 6 terminal. When LINKS operation is enabled
in Programming Section [24], Zone 6 will be automatically configured for LINKS operation.
If the control panel is programmed for End-of-Line Resistor zones (see Section [12] Zone Light 5), connect a
1000Ω resistor between the LINKS1000 RING terminal and the control panel Zone 6 terminal. If the control
panel is programmed for normally-closed zones, do not connect a resistor between these terminals.
PC1575 and PC1580
PGM2 configured for LINKS Answer allows downloading to be performed in the event of phone line failure.
WhentheLINKS receives aphonecall,itwill activatetheRINGterminalonthe LINKScircuitboard.ThePGM2
programmed as LINKS answer always requires a 2200 ohm resistor. The LINKS answer zone must be wired
with a RM-1 relay as shown in the hook-up diagram.
PC2550 and PC3000
Connectthe LINKSRING terminaltothe controlpanel’s AUX inputto provideaforced answerfor downloading
purposes. Refer to the “Programming” section of this manual for information on programming the PC2550 and
PC3000 control panels to enable the “forced answer” option.

Bat TBL Terminal
When jumper J1 is shorted, this terminal will be disabled, and the battery trouble will be reported to the control
panel through the LINKS SYS Tbrl terminal.
When jumper J1 is removed, this terminal will provide the output for the LINKS1000 battery trouble indication
to the control panel. The terminal will switch to ground after the time-out delay for the battery trouble has
expired, and remain at ground until the battery is restored. A missing battery will also cause the same
conditions.Connect toaseparate controlpanelzone thatis programmed asLINKS Supervisory. Asingle end-
of-line resistor MUST be used on this zone. (See hook-up diagram for correct resistor value.)
AC TBL Terminal
When jumper J1 is shorted, this terminal will be disabled, and the AC trouble will be reported to the control
panel through the LINKS SYS Tbrl terminal.
WhenjumperJ1isremoved,this terminalwillprovidetheoutputfortheLINKS1000AC troubleindicationtothecontrol

untiltheACisrestored.Connecttoa separate control panelzone thatis programmedas LINKS Supervisory.A single
end-of-line resistor MUST be used on this zone. (See hook-up diagram for correct resistor value.)
Battery Connections
Do not connect the battery or the transformer until all other wiring is complete. Connect the RED battery lead
to the positive battery terminal and the BLACK lead to the negative battery terminal. If the battery connection
is made in reverse, the solid state battery fuse will open. If the fuse opens, disconnect the battery and wait
for approximately 40 seconds for the fuse to reset. Note that the unit will not power up on battery power only;
AC power must first be present (with J2 open). When J2 is shorted, only the DC source connected to the
battery leads should be present.
Jumper J1
Jumper J1 is used for the LINKS1000 trouble outputs. When J1 is shorted, all of the LINKS1000 troubles will
activate the SYS Tbl output after their respective delays have expired. When J1 is open, the LINKS1000 AC

LINKS1000 troubles will activate the LINKS SYS Tbl terminal.
Jumper J2
JumperJ2isusedtoallowtheLINKS1000tobepoweredonly by a DCsource. Jumper J2 mustremain shorted
for the entire time the LINKS1000 is powered by the DC source. When all wiring is complete, place the jumper
on J2 and then connect the DC source (observing correct polarity) to the battery leads of the LINKS1000.

RELOCATING THE ANTENNA
Use only the Extension Kits to extend the mounting range of the antenna. Do not cut or splice the
extension cable.
The maximum distance between the LINKS and the antenna is 25 feet (7.62 m) as obtained
byusing theLAE-25ExtensionKit. Makesuretheantenna isina physically securedlocationto avoidtampering.
Secure the TNC connector from the Extension Kit to the mounting bracket, ensuring that the star washers make
solid electrical contact with the mounting bracket.
Remove the antenna from the LINKS cabinet and connect the extension cable to the TNC connector on the
cabinet. Secure the antenna to the TNC connector mounted on the Extension Kit Mounting Bracket.
Locate the mounting bracket and antenna away from possible sources of electrical interference. Moving the
antenna just a short distance will likely be adequate. Temporarily secure the mounting bracket in the new
location and repeat steps 1 - 3 above. If the test gives a good result, perform a test transmission as described
in the “Operations” section of this manual.
If the test is successful and the cellular transmission is completed without a Loss of Cellular Communication
trouble, permanently secure the mounting bracket and antenna at the new location.
Before permanently mounting the LINKS1000 in it’s final location, verify that it is working as it should by
following these steps:
Step 1: Make all connections between the LINKS and the control panel.
Step 2: Power up the control panel and the LINKS1000.
Step 3: Using the four LED’s on the upper left-hand side of the LINKS1000, find the position that gives the
LINKS the best signal strength:
L3 (top, green LED) lit: indicates best received signal strength. Mount the LINKS here.
L4 (second green LED) lit: indicates acceptable signal strength. The LINKS may be mounted here.
L5 (yellow LED) lit: indicates poor signal strength. DO NOT mount the LINKS here as it will probably not
be able to communicate properly.
L6 (red LED) lit: indicates very bad or no received signal strength. DO NOT mount LINKS here, as it will
not be able to communicate.
Ifasuitablelocation is notavailablewithinthemaximum3ftwirelength from thecontrolpanel,obtainanAntenna
Extension Bracket kit from your DSC / Sur-Gard supplier. Each kit contains an extension cable, a mounting
bracket, instructions, and all required mounting hardware. Three lengths of extension cable are available:

PROGRAMMINGCONTROLPANELSFORLINKS1000
IMPORTANTNOTE
WhenacontrolpanelisprogrammedforLINKS1000,thePGMoutputisdedicatedtoLINKScommunicator
and cannot be used for other functions.
Preamble Section of Control Panel Programming
The LINKS1000 receives the telephone number to be dialed from the alarm control panel
telephone number
memory location. The ‘data’ is sent via the PGM/PGMIn connection. The ‘Preamble’ programming section of the
alarm control allows for flexible dialing strings. This helps the installer use the most effective cellular plan available.
The‘Preamble’allowstheinstallertoaddaprefixoranareacodetothetelephonenumbershouldthecellularnetwork
needadditional dialingdigits.Insome areas,dialingthecentral monitoringstationmay only requiresevendigits when
using land line, while cellular requires an area code plus seven digits when accessing the network. Still other areas
mayrequirewhatisknownas‘1plus’dialing.Thatis,thecellular network requires a‘1’ be added tothe local telephone
number.Andofcourse,ifthecellulartelephoneissetupin‘Roam’modeaPreamblemayberequired.‘Roam’isawhen
a cellular phone is being used outside of the area where the telephone number originated.
If there is a question as to whether a ‘Preamble’ is needed, simply dial the central station from the premises
land line, then, dial the number using the installed LINKS1000. If both calls connect, do not add a ‘Preamble’.
To add a ‘Preamble’ simply enter the additional digits required in the location provided (see Control Panel
Programming section). The ‘Preamble supports up to 4 digits and they will always be dialed in front of the telephone
numberinthe controlpanelmemory.Factory default of‘Preamble’locationis FFFF. Programallunuseddigitsas “F”.
If Lindsay Communications is used for cellular service, a ‘Preamble’ may be required (see Helpful Hints). This
is because Lindsay’s cellular telephone numbers originate in Boston, Massachusetts. And, unless the
LINKS1000 is being connected in Boston, Mass., the device will be in ‘Roam”.
Some Helpful Hints:
Never enter a Preamble if the central station telephone number is a 1-800 number. This would result in the
control panel sending 1-800-1-800-xxx-xxxx when utilizing the LINKS1000.
Never enter a ‘Preamble’ if the telephone number of the land line telephone number to the central station is
a long distance number. Again, this would result in 1-508,1-508-xxx-xxxx being sent to the LINKS1000.
Communication Formats
Due to limitation of the cellular telephone network, only certain communication formats are recommended
when the LINKS1000 is utilized:
Recommended: • Any format communicating at 10bps or 20bps • Contact ID
• SIA format • Sur-Gard 4/3
Not Recommended: • Any format communicating at 40bps
NOTE
:ThepagerformatcanalsobeusedwiththePC5010,PC1555,PC1565,PC5015,PC5008,
PC580 and PC585 if necessary.
UL has verified compatibility with the Sur-Gard SG-MLR2-DG receiver.
If the cellular transmission is not completed successfully or there is a trouble indication, relocate the mounting
bracket and test the LINKS again.
NOTE: Do not secure the mounting bracket in a way that would stretch or strain the extension
cable. Rather than try to strain the cable to reach a desired location, use a longer cable. When
installationiscomplete,securetheextensioncablesothatitdoesnotdangleorhangloosefrom
