The Dual Door Controller (DDC) features two (2) unsupervised alarm inputs that can be used for power fault and external (cabinet) tamper monitoring. These inputs are connected using the PFL (power fail) and EXTMP (external cabinet tamper) contact terminals located on the Dual Door Controller.The PFL and EXTMP inputs are simple N/C (normally closed) contact closure monitors.Wire the PFL and EXTMP inputs using twisted pair cable, 30 ohms maximum (No EOL resistors are required).424 — revision 6Hardware Installation GuideNote:Input status LEDs will be off when the tamper device is in the closed position or the jumper is installed.External (cabinet) tamper: Configure by connecting a tamper device across pins 3 & 4 of J27 on the DDC. If not used, a jumper must be installed across pins 3 & 4 of J27.Power fail: Configure by connecting pins 1 & 6 of J27 to power fail device. If not used, a jumper must be installed across pins 1 & 6 of J27.87.7Power and Communications
