Tecom* Challenger10 / ChallengerSE Memory Expansion Module (S3971A)

The TS1084 Memory Expansion Module expands the user capacity of the Challenger10/ChallengerPlus panels to 65,535 users, from the standard 2,000 users, all of whom can have personal identification numbers (PINs). The module contains two copies of its database: one active copy and one backed up to a microSD card (supplied). During normal operation the TS1084 will check the database on the microSD card to confirm that the active database is not corrupt. If a problem is detected, the module will attempt to repair itself and will continue functioning without interruption. This background self-healing is invisible to uses and provides uncompromising stability
