The Field Interface Module FIM is the main interface for field wiring on MZX detection panels and contains plug-in field wiring terminals, inter board connectors, EMC protectors and filters and general I/O electronics. The FIM801 provides 1 x MZX DIGITAL loop and the FIM802 provides 2 x MZX DIGITAL loops. Each MZX DIGITAL loop can support several kilometres of loop wiring using a mixed topology using multiple loops and spurs.
The FIM provides up to 495mA of loop power to each loop to drive loop powered sounders and other loop power devices. An optional plug-in additional loop cards (XLM800-MX) provide up to 8 x MZX Digital loops.
