It provides transient voltage surge suppression on AC power lines running to fire alarm control panels and associated equipment. The parallel configuration allows the unit to clamp and divert surge energy without interrupting the protected circuit under normal operating conditions. The lockout feature disables the protected circuit when the suppressor reaches end-of-life, preventing unprotected equipment from remaining in service. Licensed fire alarm technicians and low-voltage electricians are the primary installers of this device.\u003c\/p\u003e\n\u003cp\u003eThis surge protector is intended for use on 120-volt AC power circuits feeding fire alarm control panels, annunciators, and related life-safety equipment in commercial and residential installations. It is suited for applications where code compliance and system integrity require verified surge protection with a clear indication of suppressor status. The lockout output provides a supervisory signal or circuit interruption to alert monitoring personnel when the unit requires replacement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParallel-wired configuration preserves circuit continuity during normal operation\u003c\/li\u003e\n  \u003cli\u003eLockout function disables the circuit at suppressor end-of-life to prevent unprotected operation\u003c\/li\u003e\n  \u003cli\u003eRated for 120-volt AC power line applications\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for fire alarm and life-safety system power circuits\u003c\/li\u003e\n  \u003cli\u003eSingle-unit form factor for straightforward panel or enclosure mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style surge protection solution for 120-volt AC power inputs on fire alarm control panels and life-safety system equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician or fire alarm technician in accordance with NFPA 72, NEC Article 285, and applicable local codes. De-energize the circuit at the breaker and verify absence of voltage before wiring. Follow the manufacturer data sheet for connection terminal assignments and ensure the lockout output is wired to a supervised circuit or indicator where required by the system design. Do not bypass or jumper the lockout contacts to defeat the end-of-life signal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e: 120 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProtection Mode\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLockout Feature\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication Category\u003c\/strong\u003e: Fire Surge Protection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DITEK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DTK-120HWLOK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DITEK","offers":[{"title":"Default Title","offer_id":51686883459378,"sku":"DTK-120HWLOK","price":156.27,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/ditek-dtk-120hwlok-120v-parallel-surge-protector-lockout","provider":"Voomi Supply","version":"1.0","type":"link"}
