The LG1093AA26 maintains stable loop continuity under elevated thermal conditions, with channel-to-channel isolation preventing interference when multiple sensors share a common panel interface.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the LG1093AA26 be replaced while the control panel is energized? A: Replacement is possible under hot-swap conditions, but the panel must be in a safe state and loop integrity maintained.\u003c\/p\u003e\n\u003cp\u003eQ: What considerations apply to cable length selection? A: Cable length options (AAx4, AAx5, AAx6) must match installation distance to avoid excess loop resistance.\u003c\/p\u003e\n\u003cp\u003eQ: Does the sensor require firmware updates? A: No. The sensor is hardware-only; compatibility depends on the receiving controller’s analog input scaling.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEngage the 3\/4 inch internal NPT threads fully to ensure mechanical stability and prevent leakage around the optical window.\u003c\/li\u003e\n\u003cli\u003eRoute the Teflon shielded cable through the one inch external conduit thread, grounding the shield at the control panel end only.\u003c\/li\u003e\n\u003cli\u003eAvoid sharp bends in the cable near high-temperature zones to preserve insulation integrity.\u003c\/li\u003e\n\u003cli\u003eKeep the optical window clear of soot or debris; periodic cleaning may be required.\u003c\/li\u003e\n\u003cli\u003eVerify gap voltage and loop continuity during commissioning to ensure proper integration.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":48696379670718,"sku":"LG1093AA26","price":560.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-07-07_16-13-19_addde300-19c7-4032-938d-434f359440c0.png?v=1784001184","url":"https:\/\/www.autooiltech.com\/ar\/products\/lg1093aa26-honeywell-lg1093-flame-sensor","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
