Security and Fire Alarm Systems Installers
Installation, Maintenance, and Repair
Work follows electrical layouts and building plans: control panels, door and window contacts, sensors, and cameras are mounted, then wired together. Cables are fed through access holes, roof spaces, or cavity walls, and holes are drilled in studs, joists, ceilings, or floors to reach the fixtures. Circuits, sensors, backup batteries, keypads, and sirens are tested against specifications; loose connections and broken insulation are tracked down and fixed. Customers get a walkthrough of how the system works and what causes false alarms. Suits people who like following codes and plans, methodical wiring, and checking that every device actually works.
