Crestron CSP-LSP Lightning Strike Protector
Cresnet® Lighting Strike
Protector: Crestron CSP-LSP
Introduction
The CSP-LSP is an accessory designed to protect a Crestron® control
system from lightning surges and other electrical disturbances brought
through the Cresnet control line. Four-stage lightning suppression
provides superior protection against damage to the control system caused
by lightning strikes to remote Cresnet devices and wiring, especially
outdoor equipment and underground cabling. It is also effective for
protection against transients picked up by indoor networks in any facility
that is particularly prone to near lightning strikes.
Features and Functions
• Sophisticated four-stage lightning suppression
• Protects control systems from surges and transients on the
Cresnet network
• Recommended for all outdoor Cresnet cable runs
• Multiple Cresnet ports for easy termination
• Includes grounding strap and clamp
The CSP-LSP provides protection for a single control system and any
portion of its Cresnet network. It may be located near the central
equipment cabinet to protect only the control system and centralized
devices, or it may be installed at the point of entry from an outdoor
Cresnet cable to protect the entire indoor Cresnet network. For networks

that span multiple buildings, a separate CSP-LSP can be installed in each
building to protect all of the local devices within each building.
The CSP-LSP is designed for mounting to a wall or similar flat surface.
Two protected CONTROL SYSTEM ports are provided, paralleled for
easy daisy chaining to a second CSP-LSP or other Cresnet equipment.
Four paralleled DEVICE ports accommodate the connections from one
or more remote Cresnet wire runs. Two #10 ground lugs provide for
termination of the grounding cable. A three foot long braided ground
wire is included, complete with a copper saddle clamp for attachment to a
suitable utility ground, cold water pipe, or grounding rod. A bus bar is
also included for daisy chaining to a second CSP-LSP unit.
