The NFPA 72 compliance, the UL listings, and the open-protocol (conventional, addressable, intelligent) compatibility with virtually every commercial fire-alarm control panel are what twenty-plus years of relentless commercial deployment has settled on as the integrator-default. For commercial fire-alarm contractors, System Sensor SKUs ship as the standard detection-tier product line across every job.</p>","top_categories_html":"<a class=\"emv-brand-hero__chip\" href=\"/access-control/fire-life-safety/fire-alarm-panels/?brand=System+Sensor\">Fire Alarm Panels</a><a class=\"emv-brand-hero__chip\" href=\"/access-control/fire-life-safety/smoke-detectors/?brand=System+Sensor\">Smoke Detectors</a><a class=\"emv-brand-hero__chip\" href=\"/access-control/fire-life-safety/heat-detectors/?brand=System+Sensor\">Heat Detectors</a><a class=\"emv-brand-hero__chip\" href=\"/access-control/fire-life-safety/co-detectors/?brand=System+Sensor\">CO Detectors</a><a class=\"emv-brand-hero__chip\" href=\"/access-control/fire-life-safety/duct-detectors/?brand=System+Sensor\">Duct Detectors</a><a class=\"emv-brand-hero__chip\" href=\"/access-control/fire-life-safety/detector-bases-accessories/?brand=System+Sensor\">Detector Bases & Accessories</a>","narrative_blocks_html":"<article class=\"emv-brand-narrative__block\"><div class=\"emv-brand-narrative__image\"><img src=\"/product_images/uploaded_images/brand_narrative/system-sensor-smoke.jpg\" alt=\"Photoelectric and ionization smoke detectors\" loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"400\"></div><div class=\"emv-brand-narrative__copy\"><h3 class=\"emv-brand-narrative__heading\">Photoelectric and ionization smoke detectors</h3><div class=\"emv-brand-narrative__body\"><p>The 2W-B / 4W-B / 2151 photoelectric and 1451 ionization smoke detector lines cover the conventional, addressable, and intelligent panel-protocol options that commercial fire-alarm panels require.
