It provides transient voltage surge suppression at the power input of fire alarm control panels and associated equipment. By clamping voltage spikes caused by lightning, utility switching, and other electrical disturbances, the DTK-DF120S1 helps protect sensitive fire detection and notification circuitry from damage. Installation is performed by licensed electricians or fire alarm technicians as part of a listed fire alarm system installation.\u003c\/p\u003e\n\u003cp\u003eThis surge protective device is suited for use in commercial and residential fire alarm system applications where 120-volt single-phase AC power is fed to a fire alarm control panel or annunciator. It is installed at the power entry point of the protected equipment, serving as the first line of defense against destructive transient events on the AC supply line. Fire alarm contractors and electrical contractors typically specify this device during new installations or system retrofits to meet authority having jurisdiction requirements for surge protection on life safety systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated for 120-volt, 20-amp single-phase AC circuits\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for fire alarm and life safety surge protection applications\u003c\/li\u003e\n  \u003cli\u003eSingle-unit form factor — one device per unit of measure\u003c\/li\u003e\n  \u003cli\u003eProvides transient voltage suppression at the protected equipment power input\u003c\/li\u003e\n  \u003cli\u003eSupports compliance with surge protection requirements for fire alarm installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style surge protective device for 120-volt single-phase fire alarm control panel power circuits in commercial and residential life safety applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician or certified fire alarm technician in accordance with NFPA 72, NFPA 70 (NEC), and local authority having jurisdiction requirements. De-energize the AC power circuit completely before connecting or disconnecting the device. Follow the manufacturer data sheet for terminal wiring sequence and mounting orientation.
