Can I keep my existing wired sensors when upgrading my alarm system?

Yes — many existing wired sensors can be reused after professional inspection. Door contacts, motion detectors, glass-break sensors, and some sirens stay when they are functional, electrically compatible, properly positioned, and in good condition. Damaged wiring, unreliable detectors, outdated life-safety devices, and poorly documented zones get replaced. ASPEX Secure tests the existing installation and designs an Ajax-based hybrid system around the components that still provide dependable value.
