Line Voltage Information
If the facility is located in an area where power lines are subject to frequent lightning
strikes, verify with the electric company that the building transformer is equipped
with surge protectors. These, as well as a “crowbar” type of protection, can be
installed at the main service entrance if the building transformer is not equipped
with lightning protection.
While lightning is one cause of power line transients, others can
b
e internal or
external to the building environment. The general application of transient surge
suppression is low-cost insurance to ensure long life of the equipment being
installed.
Wiring Input/Output Devices
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 in the
enclosure, and programmed in the controller.
