MDF -300 Operation - Each MDF -300 uses two of 99 (MS -9200 or MS- 92000D) or 159 (MS -9600) available MOUNTING DIAGRAM module addresses on an SLC loop. It responds to regular for standard -sized modules polls from the control panel and reports its type and the status (open /normal /short) of its Initiating Device Circuit (IDC). A flashing LED indicates that the module is in com- munication with the control panel. The LED latches steady (rIff on alarm (subject to current limitations on the loop).
