WARNING Please Read Carefully
Note to Installers
This warning contains vital information. As the only individual
in contact with system users, it is your responsibility to bring
each item in this warning to the attention of the users of this sys-
tem.
System Failures
This system has been carefully designed to be as effective as
possible. There are circumstances, however, involving fire, bur-
glary, or other types of emergencies where it may not provide
protection. Any alarm system of any type may be compromised
deliberately or may fail to operate as expected for a variety of
reasons. Some but not all of these reasons may be:
Inadequate Installation
A security system must be installed properly in order to provide
adequate protection. Every installation should be evaluated by a
security professional to ensure that all access points and areas
are covered. Locks and latches on windows and doors must be
secure and operate as intended. Windows, doors, walls, ceilings
and other building materials must be of sufficient strength and
construction to provide the level of protection expected. A
reevaluation must be done during and after any construction
activity. An evaluation by the fire and/or police department is
highly recommended if this service is available.
Criminal Knowledge
This system contains security features which were known to be
effective at the time of manufacture. It is possible for persons
with criminal intent to develop techniques which reduce the
effectiveness of these features. It is important that a security sys-
tem be reviewed periodically to ensure that its features remain
effective and that it be updated or replaced if it is found that it
does not provide the protection expected.
Access by Intruders
Intruders may enter through an unprotected access point, cir-
cumvent a sensing device, evade detection by moving through
an area of insufficient coverage, disconnect a warning device, or
interfere with or prevent the proper operation of the system.
Power Failure
Control units, intrusion detectors, smoke detectors and many
other security devices require an adequate power supply for
proper operation. If a device operates from batteries, it is possi-
ble for the batteries to fail. Even if the batteries have not failed,
they must be charged, in good condition and installed correctly.
If a device operates only by AC power, any interruption, how-
ever brief, will render that device inoperative while it does not
have power. Power interruptions of any length are often accom-
panied by voltage fluctuations which may damage electronic
equipment such as a security system. After a power interruption
has occurred, immediately conduct a complete system test to
ensure that the system operates as intended.
Failure of Replaceable Batteries
This system’s wireless transmitters have been designed to pro-
vide several years of battery life under normal conditions. The
expected battery life is a function of the device environment,
usage and type. Ambient conditions such as high humidity, high
or low temperatures, or large temperature fluctuations may
reduce the expected battery life. While each transmitting device
has a low battery monitor which identifies when the batteries
need to be replaced, this monitor may fail to operate as
expected. Regular testing and maintenance will keep the system
in good operating condition.
Compromise of Radio Frequency (Wireless) Devices
Signals may not reach the receiver under all circumstances
which could include metal objects placed on or near the radio
path or deliberate jamming or other inadvertent radio signal
interference.
System Users
A user may not be able to operate a panic or emergency switch
possibly due to permanent or temporary physical disability,
inability to reach the device in time, or unfamiliarity with the
correct operation. It is important that all system users be trained
in the correct operation of the alarm system and that they know
how to respond when the system indicates an alarm.
Smoke Detectors
Smoke detectors that are a part of this system may not properly
alert occupants of a fire for a number of reasons, some of which
follow. The smoke detectors may have been improperly
installed or positioned. Smoke may not be able to reach the
smoke detectors, such as when the fire is in a chimney, walls or
roofs, or on the other side of closed doors. Smoke detectors may
not detect smoke from fires on another level of the residence or
building.
Every fire is different in the amount of smoke produced and the
rate of burning. Smoke detectors cannot sense all types of fires
equally well. Smoke detectors may not provide timely warning
of fires caused by carelessness or safety hazards such as smok-
ing in bed, violent explosions, escaping gas, improper storage of
flammable materials, overloaded electrical circuits, children
playing with matches or arson.
Even if the smoke detector operates as intended, there may be
circumstances when there is insufficient warning to allow all
occupants to escape in time to avoid injury or death.
Motion Detectors
Motion detectors can only detect motion within the designated
areas as shown in their respective installation instructions. They
cannot discriminate between intruders and intended occupants.
Motion detectors do not provide volumetric area protection.
They have multiple beams of detection and motion can only be
detected in unobstructed areas covered by these beams. They
cannot detect motion which occurs behind walls, ceilings, floor,
closed doors, glass partitions, glass doors or windows. Any type
of tampering whether intentional or unintentional such as mask-
ing, painting, or spraying of any material on the lenses, mirrors,
windows or any other part of the detection system will impair its
proper operation.
Passive infrared motion detectors operate by sensing changes in
temperature. However their effectiveness can be reduced when
the ambient temperature rises near or above body temperature or
if there are intentional or unintentional sources of heat in or near
the detection area. Some of these heat sources could be heaters,
radiators, stoves, barbeques, fireplaces, sunlight, steam vents,
lighting and so on.
Warning Devices
Warning devices such as sirens, bells, horns, or strobes may not
warn people or waken someone sleeping if there is an interven-
ing wall or door. If warning devices are located on a different
level of the residence or premise, then it is less likely that the
occupants will be alerted or awakened. Audible warning devices
may be interfered with by other noise sources such as stereos,
radios, televisions, air conditioners or other appliances, or pass-
ing traffic. Audible warning devices, however loud, may not be
heard by a hearing-impaired person.
Telephone Lines
If telephone lines are used to transmit alarms, theymay be outof
service or busy for certain periods of time. Also an intruder may
cut the telephone line or defeat its operation by more sophisti-
cated means which may be difficult to detect.
Insufficient Time
There may be circumstances when the system will operate as
intended, yet the occupants will not be protected from the emer-
gency due to their inability to respond to the warnings in a
timely manner. If the system is monitored, the response may not
occur in time to protect the occupants or their belongings.
Component Failure
Although every effort has been made to make this system as
reliable as possible, the system may fail to function as intended
due to the failure of a component.
Inadequate Testing
Most problems that would prevent an alarm system from operat-
ing as intended can be found by regular testing and mainte-
nance. The complete system should be tested weekly and
immediately after a break-in, an attempted break-in, a fire, a
storm, an earthquake, an accident, or any kind of construction
activity inside or outside the premises. The testing should
include all sensing devices, keypads, consoles, alarm indicating
devices and any other operational devices that are part of the
system.
Security and Insurance
Regardless of its capabilities, an alarm system is not a substitute
for property or life insurance. An alarm system also is not a sub-
stitute for property owners, renters, or other occupants to act
prudently to prevent or minimize the harmful effects of an emer-
gencysituation.

Section 1: Introduction
This manual shall be used with the Installation Manual of the associated Alarm Controller for installation.
T-Link TL250/TL300
The T-Link TL250/300 modules are network internet communicators that send alarm system
information to a central station receiver. The module is pre-programmed with the most com-
monly used settings for quick installation. Default options can be custom programmed using
T-Link Console software if required.
T-Link TL300
The T-Link TL300 connects directly to the telephone output of a control panel and simulates a tele-
phone connection, that sends predefined Contact ID codes to the central station using the UDP proto-
col. The T-Link TL300 on-board zones can be used as in mode 2 (4-zone stand-alone) and mode 3 (12-
zone stand-alone). Modes 1,4 and 5 are not supported.

Section 2: Quick Start
2.1 Installation
1. Determine the Operating Mode Required
The operating mode (Modes 1, 2, 3, Standard Mode, or DVACS Mode) will determine how the
unit is to be wired.
2. Determine the Mounting Location
Select a mounting location in a dry, protected area at least 30cm away from physical contact
with any person. Refer to Appendix C, for Network Protection details.
NOTE: Do not exceed the following recommendations for wire run distances.
• Input wiring should must be minimum 22 gauge quad (0.5mm). Two pair twisted is preferred.
• PC5108 zone wiring must not exceed 1,000'/305m (in wire length) from the TL250/TL300.
• Do NOT use shielded wire for the keybus. Shielded wire will reduce the effectivedistance of the
keybus.
• Refer to section 9, Programming Descriptions, section [36] for zone wiring details.
3. Route Wiring to Mounting Location

Section 6: DVACS Installation (Mode 5, TL250 only)
6.1 DVACS Panel Installation.
Remove power from the control panel before wiring connections to the T-Link TL250 module.
Connect the + and - terminals to the panel auxiliary power output. Connect the DVACS cable
from the T-Link TL250 Adaptor on the PC-Link header to the DVACS connector on the control
panel. Connect the e-ground to a proper earth-ground connection.
In a typical DVACS Installation, a DVACS panel is connected to an F1/F2 subset that communi-
cates the alarm information to the central station comprising an SG MRL2 receiver with an SG
DVL2A module installed.
To send DVACS Alarm information over the internet, the T-Link TL250 performs the equivalent
functions of the F1/F2 subset and the polling function of the SG DVL2A. DVACS alarm infor-
mation is sent to the T-Link TL250 by connecting the existing RJ-45 terminated cable to the PC-
Link Header on the TL250 module with an RJ-45 to PC-Link adaptor. The TL250 transmits
DVACS alarm information in the DVACS protocol and T-Link Alarm information in the SIA
protocol over the internet to a System III Receiver with SG-DRL3-IP line card installed.
6.2 DVACS Events
DVACS events generated on DVACS panels connected through the T-Link TL250 follow the
same protocols used on the SG-DVL2A module.

Section 7: T-Link TL300 Telephone Simulation (TL300 only)
7.1 T-Link TL300 Panel Installation
• Disconnect the AC Power and battery from the Control Panel
• Secure the T-Link TL300 module to the side of the cabinet of the control panel or install the
TL300 in a DSC enclosure (model PC5003C). Refer to Appendix B: T-Link TL300 Compatibil-
ity Chart for a list of panels supported
• Wire the panel's 12VDC and GND terminals or a unit with a 12VDC 360 mA UL Listed Power
supply to the TL300 (Hardware Revision 05 or higher: 24V 360 mA UL Listed Power Supply
can also be used. Hardware revision is indicated on the PCB and the input terminal will be
labelled + and - and 12-24Vdc will be indicated).
• Wire the panel's Tip and Ring terminals to the T1 and R1 terminals of TL300
• Apply AC and DC to the main control panel. Both the TL300 and the panel should power up
• Program the T-Link TL300 as instructed in section 9.4
7.2 T-Link TL300 Operation
Communication events between the panel, TL300 and the Central Station receiver are as follows:
• When an alarm triggers, the panel goes off-hook.
• The T-Link TL300 module sends a dial tone to the panel.
• The panel dials the telephone number of the central station.
• The T-Link TL300 detects the DTMF dialing and stops sending the dial tone.
• The T-Link TL300 sends a request to the Receiver.
• The Receiver responds with the command to the TL300 to generate the corresponding handshake.
•
After receiving the handshake, the Panel transmits the alarm message in DTMF Contact ID format .
• The T-Link TL300 decodes and transforms DTMF digits into an IP packet and sends it to the
Receiver over IP.
• The Receiver acknowledges alarm and sends command to the T-Link TL300 to generate a corre-
sponding kiss-off signal.
• After the TL300 generates kiss-off, the panel goes on-hook if no more alarms need to be sent.
NOTE: Do not connect the alarm panel or TL300 to a telephone line.(!)

Section 8: T-Link TL250/TL300 Operation
8.1 Remote Control
The panel and the DLS software will control this function. The module will be a conduit for the
information. Commands can be sent from the DLS or SA software to allow control of the panel;
Arm/Disarm, Bypass/Un-Bypass, Status Request.
NOTE: DLS2002 and DLS2002SA drivers are required for the PC1616/1832/1864, PC5020 v3.2 and PC4020
v3.31. DLS IV may be used with PC1616/1832/1864 v4.2 and higher only. These drivers can be downloaded
free from www.dsc.com. DLS2002 and DLS2002SA can communicate directly to the T-Link TL250 module.
The DLS software can be used with UL Listed installations only when service personnel are on-site.
8.2 Programming
The T-Link TL250/TL300 can be programmed remotely or locally with the T-Link Console Soft-
ware via the ethernet connection or locally with the T-Link console via the serial port. Program-
ming can also be done through the control panel when connected to a PC1616/1832/1864,
PC4020 or PC5020. NOTE: TL250 programming cannot be done using DLS software.
NOTE: On a default unit the T-Link can be reached from the console at IP 192.168.0.99 with a subnet mask
of 255.255.0.0 on port 3064.
8.3 IP Address
Each TL250/TL300 on the same network node must have a unique IP address. This system is
compatible with any device that masks the IP address of the originating device. Dynamic
addressing (DHCP) can also be used with the TL250.
For remote programming, the IP must be known by the T-Link console or the DLS/SA com-
puter(s). For this reason, DSC recommends a Static IP or setting up the DHCP server to always
license the same IP to the TL250/TL300 based on its MAC address.
8.4 Port Usage Table
NOTE: Confirm with the network administrator that the following ports are locked open and that the SG-
DRL3-IP has network access for all required network segments.
8.5 Integrated Call Directions
The T-Link TL250/TL300 features a built-in call direction that will allow signals to be sent to
active receivers as well as a local LAN logging application.
The T-Link TL250/TL300 has a choice of 3 receivers when transmitting signals. Receiver 1,
Receiver 2 and Receiver 3. Should the communications be lost to Receiver 1, the TL250/TL300
will generate a local trouble and send the trouble to the appropriate receiver. The loss of Receiver
2 or 3 does not generate any signal since they are not supervised.
The panel can direct to which receiver the signal will be sent. If a Receiver is lost, the TL250/300
will route the alarm to the backup receiver (if programmed). Receiver 3 will be used for local log-
ging. Any signal sent to Receiver 1 or Receiver 2 will also be sent to Receiver 3. Once the con-
nection has been reestablished to Receiver 1, the TL250/TL300 will resume transmission to it.
NOTE: If Receiver 1, 2 or 3 is not programmed, TL250/TL300 will not attempt to report to the receiver.
NOTE: Receiver 2 is not supported for DVACS installations.
NOTE:Transmissions to receiver 3 are not gaurenteed.

8.6 Status Indicators
There are 4 LEDs on the board to indicate connection, traffic and trouble conditions.
LK LED (Link Status) will turn on when the network is present and will turn off when the net-
work is absent.
ACT LED (Activity/Network Traffic Status) will blink to show network activity.
SPD LED (Speed Status) will remain off for 10BaseT network connection and will be on to indi-
cate 100BaseT network connection.
STAT (Status) LED will normally blink once every 5 seconds. If a trouble is present, the LED
will blink a number of times (as per table) with a one second pause before restarting the
sequence. If there is more than one trouble present, the LED will blink at a rate that is equal to
the highest priority.
Example: The network is not present and inputs are in alarm. The LED will blink once with a
one-second pause. When the network trouble is cleared the LED will blink five times with a
one-second pause.
The transmitter has a number of individually maskable trouble conditions that report various
troubles present on the transmitter. For the corresponding trouble toggle option, refer to section
[033] and [034]. Options [033] and [034] can be set to ignore for any or all trouble conditions.
Once a trouble is ignored, it no longer generates a signal or has any affect on the Status LED.
8.7 Testing & Troubleshooting
The T-Link TL250/TL300 and the Sur-Gard System I IP, System II or System III Receiver can
be connected directly with an Ethernet crossover cable. An Ethernet crossover cable can be
made by taking a standard Ethernet cable (which will have wires attached to pins 1, 2, 3 and 6
only on the 8 pin RJ-45 connector) and swapping pin 1 with pin 3, and also swapping pin 2
with pin 6, on one end of the cable only. This effectively reverses the transmit and receive
pairs, and allows two hosts to communicate without the use of a network hub.
Upon T-Link power-up (without the Ethernet cable connected), LED2 will blink periodically,
approximately once every 12 seconds. This represents the T-Link TL250 attempting to send a
connection request to the receiver. The TL250 will try to connect to the receiver until it succeeds.
The Activity and Link LED’s are normally OFF in their default state after power-up (i.e. when
no Ethernet cable is connected, and there are no packets being transmitted or received, respec-
tively). Refer to the Status Indicator table above for details.
Status Blinks/
Priority Description
Network Absent 1The Ethernet link between the transmitter and local hub or router is absent. This is equivalent to the link LED on the Ethernet chip
being off.

mation about the DHCP settings.
IMPORTANT!: If a telephone line is used to back up communication, program the phone number you want
to use as a backup or dial direction option in section [000401] ‘Communication Toggle Options’. If using
PC4020, PC5020 or PC1616/1832/1864, [380] Option [5] enables 3rd number to backup. DSC recommends
programming the TL250/TL300 to transmit first for faster communication. If the land line communication is
programmed to communicate first, then the TL250/TL300 communication will be delayed for the duration of
the land line call (30-45 seconds). This also applies when using the phone line for backup only.
9.1 T-Link TL250 Basic Programming (PC4020 Control Panel)
NOTE: PC4020 v3.3 or higher required (Rev04B hardware).
DSC recommends changing the reporting code transmission delay from 20s to 40s on the PC4020:
Step 1 Power down the MAXSYS panel.
Step 2 Power up the MAXSYS panel. Enter Installer Programming ([4][8][Installer Code] within
the first 10 minutes of power up.
Step 3 Scroll to Diagnostics (04) and press [4].
Step 4 Scroll to Binary Programming (01) and press [4].
Step 5 Enter the address of the address location 03044 and change the value to 28, this will change
the time to 40 seconds.

Step 1: Program the Hex digits [CAAA] in the telephone number that will be used for T-Link TL250
communications (section [0004000000] ‘Communicator + Main Items Phone Numbers’).
NOTE: You must delete the [D] in the telephone number first (this is the dial tone detection).
Step 2: Program YES for ‘T-Link Enabled’ option, section [000401] ‘Communication Toggles’.
Step 3: If using DLS communication over the TL300 then program YES for ‘DLS Enabled’ in sec-
tion [000300], ‘DLS Section +DLS Toggles’.
Step 4: Program the dialer direction options for the phone number that has been programmed to send
T-Link communications in section [000400XX02], where XX = telephone number 00-02 in
the ‘Communicator + Main Options’.
NOTE: Auto report SIA section [000401] must be enabled in order for the T-Link TL250 to communicate.
The communication format must be programmed for SIA [000400XX01].
Step 5: Enter section [000406] for T-Link TL250 module programming options.
NOTE: Data must be entered within a 14-second window. Exceeding the 14s limit will result in the following
sequence: a tone will sound, exit from the programming section, all data previously entered will be lost.
Step 6: Program the static IP address for the T-Link TL250 module in section [001]. Program
000.000.000.000 for DHCP.
Step 7: Program the subnet mask for the T-Link TL250 module in section [002]. This option will be
ignored if the unit is set for DHCP.
Step 8: Program the receiver static IP address (DRL3-IP line card or the PC running The Reporter IP
software in section [007].
Step 9: If the Sur-Gard receiver is on a different network segment than the T-Link TL250 module,
the gateway address associated with the TL250 module must be programmed in section
[008]. This is an optional step; determine if this is required with the network administrator.
Step 10: Program the T-Link TL250 account number in section [003].
NOTE: The T-Link account number can be up to 10 digits long. If account number is less then 10 digits lead-
ing zeros must be entered.
Step 11: When TL250 Programming is completed perform the following for programming changes to
take effect. In T-Link Programming Section [999], enter digits [55][#]. It will take approxi-
mately 15s for the module to reboot. Press the [#] key to exit T-Link TL250 programming.

Maxsys V3.5 Only:
If the panel sends events to Receiver 0, the T-Link will perform backups automatically to IPs
from Receiver 1 and Receiver 2. If the panels sends events to specific receivers then the
panel will be responsible for all backup/alternate dial functions.
NOTE: The IP Receiver addresses are programmed in the T-Link TL250.
9.2 T-Link TL250 Basic Programming (PC1616/1832/1864, PC5020 Panels)
NOTE: PC1616/1832/1864 or PC5020 software version 3.2 or higher required (Rev03 hardware).
Programming Steps:

communications (section [301] to [303], ‘Telephone Phone Number Programming’).
NOTE: The leading digit [D] in the telephone number for dial tone detection is already programmed.
Step 2: Program the communication format as SIA FSK format in section [350] and Auto SIA,
option 3 in section [381] has to be OFF.
Step 3: Program the call direction options in section [351] to [376] for the phone number being used
to communicate using T-Link TL250.
Step 4: Section [382] Option 5 ‘PC-Link Active’ option must be ON to enable T-Link TL250 com-
munication.
Step 5: Enter section [851] for T-Link TL250 module programming options.
NOTE: Option [5] in Section [382] must be enabled to access this section.
NOTE:Data must be entered within a 14-second window. Exceeding the 14s limit will result in the following

mately 15s for the module to reboot. Press [#] key to exit T-Link TL250 programming.
9.3 T-Link TL250 DVACS Programming
Obtain the following information from the station monitoring the DVACS alarm panel:
1. The SG-DVL2A Receiver number and line number that the DVACS panel is connected to.
2. The DVACS panel ID (Account Number).
3. The programmed value of the SG-DVL2A extended format (Option [07]) for step 2 below.
Step 1: Program the Account Number of the DVACS control panel in the DVACS account option of
the T-Link (Option [067]). The T-Link will use this number to supervise the control panel
and poll for DVACS signals from the panel.
NOTE: Alarms generated by the DVACS panel will be sent using the T-Link account.
Step 2: Program the T-Link DVACS extended Option [068] so that it is identical to the SG-DVL2A
extended option 07.
Step 3: Program the T-Link Account (Option [003]). To use the DVACS account number for alarm
reporting, program the T-Link account option with this value.
When an alarm is sent from the DVACS control panel to the central station, the account number is
expanded to a 10-digit value. The first four digits emulate the line number and receiver number on the
CAAA = Receiver 0 CCCC = Receiver 2
CBBB = Receiver 1 CDDD = Receiver 3

16
MLR2/DVL2A. These four digits overwrite the SG-DRL3-IP receiver and line number before being
sent to the printer and computer. This allows existing DVACS accounts to be sent to the automation
software without alteration and account duplication on the same SG DRL3-IP line card using a differ-
ent line and/or receiver number.
NOTE: If a new account is created, the first four digits must be programmed as ‘0000’.
9.4 T-Link TL300 Programming
Step 1: Program the static IP address for the T-Link TL300 module in section [001].
Program 000.000.000.000 for DHCP.
Step 2: Program the subnet mask for T-Link TL300 in section [002] if required.
This option will be ignored if the unit is set for DHCP (Section [001])
Step 3: Program the T-Link account number in section [003].
NOTE: The T-Link account number can be up to 10 digits long. If account number is less then 10 digits lead-
ing zeros must be entered.
Step 4: Program the static IP address of the receiver (DRL3-IP line card) in section [007].
Step 5: If the Sur-Gard receiver is on a different network segment than the T-Link TL300 module,
program the gateway address associated with the T-Link TL300 in section [008].
NOTE: This step is optional. Verify with the Network Administrator if this step is required.
Step 6: If a specific dial tone is required for the panel connected to T-Link TL-300 T1/R1, refer to
section [071].
