The B5512 Control Panel integrates intrusion and residential fire, providing one simple user interface for both systems. The B5512 provides up to 48 individually identified points that can be split into 4 areas. The control panel can communicate through its built-in Ethernet port (not applicable to “E” control panels), or through compatible plug-in modules that can send events over the public switched telephone network (PSTN) or over cellular network communications.
