The Ademco LynxR-2 is a self contained wireless Alarm System. The main unit contains the control panel, keypad, siren, dialer, two-way voice system, and speakerphone. The LYNXR-2 is capable of turning on and off appliances, full voice response, remote phone control, quick exit, plus much more. The convenient voice prompt programming feature will walk you through the installation steps. The voice annunciation of status and alarms reduces the amount of end-user training. This new version of the Lynx will also support the 5828 and 5828V wireless keypads.
