The Ditek DTK-120HWLOK is a parallel-mounted, 120VAC/20A surge protective device (SPD) built specifically for life safety branch circuits, such as fire alarm control panel power feeds. It mounts alongside the protected circuit in a NEMA 4X weatherproof enclosure and includes a lockout kit that satisfies NFPA 72 (2022) requirements preventing accidental disconnection of a circuit critical to fire alarm operation.
