These inputs are connected using the PFL (power fail) and EXTMP (cabinet tamper) contact terminals on the Input Control Module board.The PFL and EXTMP inputs are simple N/C (normally closed) contact closure monitors. Connect the power fail monitoring device to J20 pins 1 & 3 and to External Tamper (cabinet tamper) pins 4 & 6. If not used, a jumper must be installed across pins 1 & 3 and 4 & 6.Note:Input Status LEDs will be off when the tamper device is in the closed position or the jumper is installed.Wire the PFL and EXTMP inputs using twisted pair cable, 30 ohms maximum. (No EOL resistors are required.)revision 6 — 281LNL-1100-U Input Control Module
