•ForUL Commercial Burglary applicationsthe TL2803G(R) E/ 3G2080R / TL280 (R)E / LE2080(R) / TL280LE(R) can be used asdual signalling
line communication system(cellularand 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/ortoggle 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(heartbeatmust be enabled)or forsupplementary(back-up)use in conjunction with a Plain Old Telephone Service (POTS)line dialer.
When the heartbeat transmission over the Ethernet orcellularnetworkisenabled, using the TL2803G(R)E/3G2080(R)E/TL280(R)Ewith a compatible
controlunitlisted forstandard/encrypted line security, it can provide line securityforthe alarmsystemoverthe 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 fordualline secur-
ity transmission when used in conjunction with a DACT ora Public Switched Data Network(PSDN)transmitter, where the PSDN providesthe line security
and isthe primaryline. In thismode, alarmsignalsare required to be sent simultaneouslyoverboth communication methods.
