Sprague GPR Configuration
and Waterproofing
Before You Begin
U WARNING: Before performing the following steps, determine the direction that the GPR will
face. The GPR must face away from nearby walls and toward the nearest MCC or
Concentrator. Refer to Appendix D, Sprague Changing GPR Direction for additional details.
Configuring the GPR
The GPR must be programmed with customer-specific requirements. The GPR, when installed for
the first time, will start operation in Install Mode. During Install Mode, the GPR will auto register to
the Network and then go through an auto-configuration process.
Applying Water Sealant to Circuit Board Connections
Dow Corning 4 Electrical Insulating Compound is recommended as a sealant to prevent water
intrusion into the GPR Pulse Input and Battery circuit board connections.
