Security Systems Lightning Protection and Grounding Design Guide
8.1 Accessories & Tools Overview
A complete security system lightning protection installation requires a range of accessories, consumables, and test instruments in addition to the primary SPD and bonding products. These items are often overlooked in initial procurement but are essential for achieving compliant installation quality, passing acceptance tests, and maintaining the protection system over its operational lifetime. The accessories list below is organized by category and includes the minimum quantity guidance for a typical medium-scale installation.

Procurement Tip: SPD replacement cartridges and Ethernet SPD spare modules should be included in the initial procurement order and stored on site. Post-storm replacement is time-critical — having spares on site reduces mean time to recovery from days (waiting for delivery) to hours (immediate replacement). Specify a minimum 20% spare ratio for power SPD cartridges and 10% for data SPD modules.
