DSC TL300 T-Link Universal IP Alarm Communicator


T-Link Universal IP Alarm Communicator

The T-Link universal IP alarm communicator (TL300) is a valuable addition to the T-Link family of Internet/network alarm communicators. Capable of  communicating with any control panel (including thirdparty manufacturers) that uses the Contact ID format, the simple-to-install TL300 saves end-users money by taking advantage of their existing IP networks and security equipment to create fully supervised security solutions between protected premises and central monitoring stations. This method provides flexibility and an always-on, two-way line of communication. The TL300 communication stream is small and requires only a limited amount of network bandwidth. This ensures that the integrity of the data being transferred never becomes compromised. To reduce security risks, the module utilizes industry-leading, 128-bit AES encryption, polling and hardware substitution protection.

How it Works

The TL300 connects directly to the telephone output of a control panel and simulates a telephone connection, providing a TCP/IP connection that sends predefined Contact ID codes to the central monitoring station.

To ensure dependable and timely event notification, the TL300 is capable of reporting to two different receiver IP addresses—a back-up feature that allows communication to continue in the event one of the IP addresses is inaccessible. The module can also be programmed to communicate events to two different e-mail addresses. These e-mail addresses can be associated with a personal computer, pager, enabled mobile phone or PDA.
