Please Note: The Uplink 2540 universal full-data cellular alarm communicator has been discontinued and replaced by the LTE30EX model number.
The Uplink 2550 is a universal full-data cellular 2G GSM alarm communicator that works with most existing alarm systems. The Uplink 2550 cellular alarm communicator delivers full-event reporting and complete end-to-end alarm signal verfication for primary wireless communications or as a backup to landline connections. The 2550 is universal, so it is virtually compatible with most existing security systems to send GSM alarm signals to GeoArm's nationwide central alarm monitoring station.
