The Floor Level Network (FLN) Controller Board controls floor level network devices such as, Terminal Equipment Controllers (TECs), Differential Pressure Monitors (DPMs), and Unitary Controllers (UCs). The controller board mounts in an enclosure and can operate independently with associated FLN devices or as part of the building level network (BLN). Once installed, the controller board is positioned approximately 2-1/4-inches off the back wall of the enclosure on a board bracket and four standoffs. The controller board has two man-machine interface (MMI) ports the MMI and the MMI MODEM which are RS-232 ports with quick-connect RJ-11 jacks.
All circuits are supervised, except for the MMI MODEM and MMI ports.
The memory board, located beneath the memory board cover and plugged into the controller board, contains the firmware that controls the FLN Controller. The memory board s flash read-only memory (ROM) stores the microprocessor instruction code, PPCL compiler, and the operator interface.
