Fire Alarm Control Panel 05
Fire Alarm Control Panel 05 : Multiplex Systems: Multiplex systems, a sort of transition between conventional and modern addressable systems, were often used in large buildings and complexes from the mid to late 1970s into the late 1980s. Early on, these systems were programmed to function as large conventional systems. Gradually, later installations began to feature components and features of modern addressable systems. These systems were often capable of controlling more than a building's fire alarm system (i. e. HVAC, security, electronic door locks. . ). without any type of alarm or trouble condition present. While the main panel was the brains of the system and could be used to access certain functions, fire alarm controls were usually accessed through transponders. These were smaller conventional panels programmed to 'communicate' the status of part of the system to the main panel and also could be used to access basic fire alarm control functions. The original Simplex 4100 was meant to be used this way
