•For UL Commercial Burglary applicationsthe TL2803G(R) E/ 3G2080R / TL280 (R)E / LE2080(R) / TL280LE(R) can be used asdual signalling
line communication system(cellular and Ethernet channelsused in redundant configuration), standard line securityand asencrypted line security.
•The supervision heartbeat shall be enabled (panel section [851][005] toggle option [1] (Ethernet) and/or toggle option [2] (cellular) shall be ON),
toggle option [3] (supervision type) shall be ON and the supervision heartbeat rate shallbe selected as135 (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 shallbe enabled at the monitoring station receiver.
•For UL Commercial Burglary installations, the TL2803G(R)E/3G2080 (R)E/TL280(R)E/LE2080 (R)/TL280LE(R) is listed as a primary (sole) com-
munication 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 or cellular networkisenabled, using the TL2803G(R)E/3G2080(R)E/TL280(R)Ewith a compatible
controlunit listed for standard/encrypted line security, it can provide line securityfor the alarmsystemover the primaryline.
•The TL2803G(R)E/3G2080(R)E/TL280(R)E/LE2080(R)/TL280LE(R) isalso suitable to be used with a compatible controlunit listed for dualline secur-
itytransmission when used in conjunction with a DACT or a Public Switched Data Network(PSDN) transmitter, where the PSDN providesthe line security
and isthe primaryline. In thismode, alarmsignalsare required to be sent simultaneouslyover both communication methods.
