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.

5.3 Wiring T-Link to a DSC Compatible Control Panel
• Secure the T-Link module to the side of the cabinet using the supplied standoffs.
• With AC power and battery disconnected removed from the DSC control panel, wire the T-Link to
the panel using 4 wires from the PC-Link of the panel to the “PANEL” connector on the T-Link.
• Wire the panel's AUX+ and - to 12VDC and GND terminals of T-Link.
• Apply AC and DC to the main control panel. Both the T-Link and the panel should power up.
• Do the necessary programming that is required.
NOTE: If a Bell/Siren will not be used, wire the Bell/Siren terminals on the panel with a 1000
ohm resistor. For Commercial Fire installation, when a bell/siren is used in the application, it
should be connected to the DSC module PC4702BP. Refer to the PC4020 Installation manual.
The keypad or any other accessory connected to the Combus shall be connected within 3 feet
/ 0.9 m and in conduit.

Section 6: DVACS Installation (Mode 5)
6.1 DVACS Panel Installation.
Remove power from the control panel before wiring connections to the T-Link TL250 module.
Connect the 12VDC and GND 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 connec-
tor 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 commu-
nicates 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 equiva-
lent functions of the F1/F2 subset and the polling function of the SG DVL2A. DVACS alarm
information 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 T-Link
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: TL300 Telephone Simulation
7.1 TL300 Panel Installation.
• Secure the T-Link module to the side of the cabinet of the control panel or install theT-Link TL300
in a DSC enclosure (model PC5003C). Refer to Appendix B: T-Link TL300 Compatibility Chart
for a list of panels supported
• With AC power and battery disconnected removed from the control panel, connect the T-L300 to
the RJ31 phone jack from the panel to the RJ31 connector on the T-Link.
• Wire the panel's 12VDC and GND terminals of T-Link or Power unit with a 12VDC 225 mA UL
Listed Power supply.
• Wire the panel's Tip and Ring terminals to the T1 and R1 terminals of T-Link TL300.
• Apply AC and DC to the main control panel. Both the T-Link and the panel should power up.
• Do the necessary programming that is required.
7.2 T-Link TL300 Operation
Communication events between the panel, T-Link and the Central Station receiver are as follows:
• When an alarm triggers, the panel goes off-hook
• The T-Link module sends a dial tone to the panel
• The Panel dials the telephone number of the central station
• The T-Link detects the DTMF dialing and stops sending the dial tone.
• The T-Link sends a request to the Receiver.
• The Receiver responds with the command to the T-Link to generate the corresponding handshake.
• After receiving the handshake, the Panel transmits the alarm message in DTMF Contact ID format
• The T-Link 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 to generate a corresponding
kiss-off signal.
• After the T-Link generates kiss-off, the Panel goes on-hook if no more alarms need to be sent.

Section 8: T-Link 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: New DLS-3 and System Administrator drivers are required for the PC5020 v3.2 and
PC4020 v3.31. These drivers can be downloaded free from dsc.com/dls3drivers.htm. DLS-3
and System Administrator 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
Software via the ethernet connection or locally with the T-Link console via the serial port. Pro-
gramming can also be done through the control panel when connected to a PC4020 or PC5020.
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 T-Link on the same network node must have a unique IP address. This system is com-
patible 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 T-Link 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 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 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 T-Link 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 T-Link
TL250 will route the alarm to the backup receiver (if programmed). Receiver 3 will be used as
a local logging. Any signal sent to either Receiver 1 or Receiver 2 will also be sent to Receiver
3. Once the connections has been reestablished to Receiver 1 the T-link will resume transmis-
sion to it.
NOTE: If Receiver 1, 2 or 3 is not programmed, T-Link will not attempt to report to the receiver.
NOTE: Receiver 2 is not supported for DVACS installations.
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
indicate 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 then one trouble present, the LED will blink at a rate that is equal
to the highest priority.
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 sec-
tion [033] and [034]. Options [033] and [034] can be set to ignore for any or all trouble con-
ditions. Once a trouble is ignored, it will no longer generate a signal or have any affect on the
Status LED.
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.

14
8.7 Testing & Troubleshooting
The T-Link TL250/TL300 and the 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 periodi-
cally, 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,
respectively). Refer to the Status Indicator table above for details.
Status Blinks/
Priority Description
Network Absent 1
The 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.

Section 9: Programming Guide
The following information is required Before programming the T-Link TL250/TL300 modules.
1. The static IP address for the T-Link TL250 module (Section [001]).
2. The subnet mask for the T-Link TL250 module (Section [002]).
3. The static IP address of the receiver (Section [007]).
4. The static IP address of the static gateway for the LAN that the T-Link TL250 is connected to in a
WAN configuration (Section [008]).
NOTE: For DHCP networks, the above items are not required. Consult your network adminis-
ter for information 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 a PC4020 or a PC5020 [380] option 5, enables 3rd number to backup. DSC recom-
mends programming T-Link TL250 to transmit first for faster communication. If the land line com-
munication is programmed to communicate first, then the T-Link TL250 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 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 installers programming ([*] + 8 + Installers Code)
within the first 10 minutes of power up.
Step 3 Scroll to Diagnostics (04) and press [*].
Step 4 Scroll to Binary Programming (01) and press [*].
Step 5 Enter the address of the address location 03044 and change the value to 40 seconds (0x28).
Programming Steps:
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 Num-
bers’).
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 T-Link then program YES for ‘DLS Enabled’ in section
[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 com-
municate. The communication format must be programmed for SIA [000400XX01].
Step 5: Enter section [000406] for T-Link module programming options.
Step 6: Program the static IP address for the T-Link module in section [001]. Program
000.000.000.000 for DHCP.
Step 7: Program the subnet mask for the T-Link 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].

16
Step 9: If the receiver (DRL3-IP) is on a different network segment than the T-Link module, the
gateway address associated with the T-Link 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’s account number in section [003].
Step 11: After all T-Link TL250 module programming is complete, you must restart the module so
the programming changes will take effect. To restart the T-Link module enter the digits
[55] in T-Link programming section [999] and wait 15 seconds for the module to reboot.
Once complete, 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 Basic Programming (PC5020 Control Panel)
NOTE: PC5020 software version 3.2 or higher required (Rev03 hardware).
Programming Steps:
Step 1: Program the hex digits [DCAA] in the telephone number that will be used for T-Link
TL250 communications (section [301] to [303], ‘Telephone Phone Number Program-
ming’).
NOTE: The leading digit [D] in the telephone number for dial tone detection is already pro-
grammed.
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.
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 static IP address of the receiver (DRL3-IP line card) in section [007].
Step 9: If the receiver (DRL3-IP) is on a different network segment than the T-Link TL250 mod-
ule, the gateway address associated with the T-Link TL250 module must be programmed in
section [008]. This is an optional step; verify with the network administrator if this is
required.
9.3 T-Link 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.
