Crestron CSP-LSP Lightning Strike Protector Hardware Hookup The CSP-LSP can be connected locally to protect a nearby control system and Cresnet devices. The CSP-LSP can also be connected to remote Cresnet devices or another CSP-LSP to provide protection to Cresnet devices that are connected with substantially longer wire runs. Make the necessary connections as called out in the illustrations below and on the next page.
Lightning Strike Protector Remote Connections Crestron CSP-LSP Remote connections refer to connections made from the locally connected CSP-LSP to Cresnet devices connected by wire runs exceeding 500 feet or wire runs situated outdoors, including wire runs underground. Cresnet devices at these distant locations are referred to as remote Cresnet devices. A CSP-LSP can be connected at a remote location to provide additional protection to a unit or a series of remote Cresnet devices.
Crestron CSP-LSP Lightning Strike Protector Operation The CSP-LSP can be connected either locally or remotely, while up to two CSP-LSP devices may be daisy chained together in either connection configuration. Local CSP-LSP Operation Locally, one of the CONTROL SYSTEM ports must be connected to the control system.
Lightning Strike Protector Crestron CSP-LSP Daisy Chaining Up to two CSP-LSP units can be daisy chained when a C2N-HBLOCK is not a practical option. Daisy chaining two CSP-LSP units provide up to four protected CONTROL SYSTEM ports. When CSP-LSP units are being daisy-chained together, connect both of the available grounding studs to a good earth ground using the grounding straps provided with each unit. 16 • Lightning Strike Protector: CSP-LSP Operations & Installation Guide – DOC.
