Tamper Switch Wiring
The tamper switch connects to a general purpose input point. To be
operational, the tamper switch must be wired to one of the unused input
points on any RDR2S-A in the enclosure, and programmed in the
controller. Use the PANEL/TAMP connector for this function.
General Input Wiring
The inputs can be used as either 2-state or 4-state inputs. You should
calibrate the inputs depending on the needs of your site.
