Internet Alarm Communicator Installation Manual
Technical Specifications
The input voltage to the Communicator can be drawn from an Underwriters Laboratories/Under-
writers Laboratories Canada (UL/ULC) listed control panel or compatible power supply module
such as HSM2204 or HSM2300.
NOTE: Power supply must be Class 2, power limited.
UL/ULC Installation Requirements
NOTE: For equipment used at the protected premises and intended to facilitate IP communica-
tions (hubs, routers, NIDs, Digital Subscriber Line (DSL), cable modems), 24 hour back-
up power is required. Where such cannot be facilitated, a secondary (back-up) communi-
cation channel is required.

Domain Name Service (DNS) programming is not permitted in UL/ULC listed
systems.
Notes for using Private, Corporate, and High Speed Data Networks:
Network access and domain access policies shall be set to restrict unauthorized network access,
and spoofing or Denial of Service (DoS) attacks. Select an Internet Service Provider (ISP) that has
redundant servers/systems, back-up power, routers with firewalls enabled, and methods to identify
and protect against DoS attacks (e.g., via spoofing).
Notes for using Public Switched Data Networks:
Communication channels shall be facilitated such that the communicator will restrict unauthorized
access, which could otherwise compromise security. The communicator shall be located in a
secured area.
• For ULC Residential Fire and Burglary applications the TL280(R) can be used as primary com-
munication channel via either Ethernet or as a back-up in conjunction with the Digital Alarm
Communicator Transmitter (DACT). Test transmission every 24 hours shall be enabled on each
channel.
• For ULC Commercial Fire and Burglary applications the TL280(R) can be used as a passive
communication module with the following security levels:
• P1 (each channel is independent)
• The communicator can also be used as an active communication system with the security levels
A1-A4 (each channel independent). For active line security systems AES128 bit encryption
shall be enabled (at the monitoring station receiver) and the supervision heartbeat rate shall be
set as 90 seconds (panel section [851][004] = 005A/90). The supervision window at the Signal
Receiver Center (SRC)'s receiver shall be programmed as maximum of 180 (00B4/180) sec-
onds.
• For UL Residential Fire and Burglary applications the TL280(R) can be used as the primary
communication channel via Ethernet, or as a back-up in conjunction with the DACT
(30 day test transmission is required on each channel).
• The supervision heartbeat shall be enabled (panel section [851][005] toggle option [1] (Ether-
net) shall be ON), toggle option [3] (supervision type) shall be ON and the supervision heart-
beat rate shall be selected as 135 (0087/135) seconds. Option [004] = 0087. The supervision
window at the supervising station shall be maximum 200 (00C8/200) seconds. For encrypted
line security systems the encryption AES128 bit shall be enabled at the monitoring station
receiver.
• For UL Commercial Burglary installations, the TL280(R) is listed as a primary (sole) commu-
nication means (heartbeat must be enabled) or for supplementary (back-up) use in conjunction
with a Plain Old Telephone Service (POTS) line dialer. When the heartbeat transmission over
the Ethernet network is enabled, using the TL280(R) with a compatible control unit listed for
standard/encrypted line security, it can provide line security for the alarm system over the pri-
mary line.
• The TL280(R) is also suitable for use with a compatible control unit listed for dual line security
transmission when used in conjunction with a DACT or a Public Switched Data Network
(PSDN) transmitter. The PSDN provides the line security and is the primary line. In this mode,
alarm signals are required to be sent simultaneously over both communication methods.
