{"product_id":"protectowire-jd-1","title":"Protectowire JD-1 Junction Box Accessory","description":"\u003cp\u003eThe JD-1 is a junction box accessory used in Protectowire linear heat detection (LHD) installations. It provides a clean transition and connection point where the continuous Protectowire heat-sensing cable terminates, splices, or routes into conduit, end-of-line hardware, or control wiring. Using a dedicated junction box keeps field connections accessible for inspection and maintenance while protecting them from mechanical damage and environmental exposure along the detector run.\u003c\/p\u003e\u003ch3\u003eCompliance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFor use within UL 521 listed Protectowire linear heat detection systems\u003c\/li\u003e\n\u003cli\u003eSupports installations designed to FM 3210 approval requirements\u003c\/li\u003e\n\u003cli\u003eIntended for application under NFPA 72 design and inspection practices\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eProvides an accessible enclosure for cable terminations and transitions\u003c\/li\u003e\n\u003cli\u003eProtects field connections from dust, moisture, and mechanical impact\u003c\/li\u003e\n\u003cli\u003eMaintains continuity of the heat-sensing cable circuit at junction points\u003c\/li\u003e\n\u003cli\u003eSupports conduit entry and end-of-line device mounting\u003c\/li\u003e\n\u003cli\u003eKeeps connections serviceable for periodic testing and re-inspection\u003c\/li\u003e\n\u003cli\u003eSuited to industrial environments where the LHD cable changes direction or transitions\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eProtectowire linear heat detection systems run a continuous sensor cable across long or distributed hazards such as tunnels, conveyor belts, storage racks, and cable trays, where spot detectors cannot provide unbroken coverage.
