How to use this library
  1. Pick a system type.
  2. Open the closest reference design.
  3. Review the diagram, assumptions and live BOM.
  4. Use the calculators or request a project-specific quote.
Reference designs are starting points. Final device placement, quantities, code requirements and site conditions must be verified for each project.

Security system design packages built for real purchasing decisions

Instead of stopping at a product category, Safsale Pre-Engineered Solutions organize compatible components into working system concepts. Video surveillance spans compact four-camera packages through 270-camera enterprise architectures; access control ranges from standalone single-door systems to 100-door campus designs; intrusion detection covers wired, wireless, hybrid and perimeter alarm systems; fire alarm includes conventional, addressable, wireless, beam, duct and voice references; intercom covers audio, video, IP/SIP, apartment visitor entry and secure-window systems; and paging/mass notification now covers 70V, SIP/PoE, visual, industrial and enterprise communication architectures.

Each design links back to actual catalog products and is supported by storage, bandwidth, PoE, UPS, access-power, battery, voltage-drop, zone, NAC, SLC, intercom, speaker-load, SPL, gate, structured-cabling, building-automation and industrial-edge calculators. The full initial solution framework is now live across surveillance, access, intrusion, fire/life-safety, intercom, mass notification, perimeter/gates, networking/cabling, power/UPS, smart building and industrial/hazardous security.
