ChallengerSE licence modules enable additional features to further enhance your security system.The TS1082 User Expansion Licence increases the number of IUM users on a ChallengerSE panel from 100 to 2,000. If the unit is removed from the panel the users above 100 will cease to work. However the users are not removed from the panel. Once the TS1082 is re-installed a download is not required for the additional users to start functioning.If a ChallengerSE control panel needs more than 2,000 users, a TS1084 Memory Expansion Module must be used in place of the TS1082 User Expansion Licence Module.The TS1091 Enhanced Communications Licence allows a permanent connection to management software. If the unit is removed the panel will revert to timing out connections after 60 minutes.
