External (Cabinet) Tamper
An external cabinet tamper is configured by connecting a tamper device
across pins 3 & 4 of J18 on the SDC. If not used, a jumper must be installed
across pins 3 & 4 of J18.
Note:
Power fail is not supported on the SDC; therefore no jumper is
required. This is labeled in the diagram as "NOT USED."
External tamper wiring
Note:
Input status LEDs will be off when the tamper device is in closed
position or the jumper is installed.
