The resistor sits at the last device on the loop and draws a defined standby current that the monitor circuit watches continuously — any deviation outside the supervision window triggers a trouble condition at the panel. The 47k ohm value is specified by Fire-Lite for the input side of MMF-300-series addressable monitor modules and several other supervised inputs; the panel or module datasheet should be consulted to confirm the correct EOL value for each circuit.\u003c\/p\u003e\n\u003cp\u003eVerify panel\/device family compatibility before ordering.\u003c\/p\u003e","brand":"Fire-Lite","offers":[{"title":"Default Title","offer_id":52004366352677,"sku":"REL-47K","price":26.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/7648\/4645\/files\/fire-lite-fire-alarms-default-title-fire-lite-rel-47k-31896815730912.jpg?v=1771296154","url":"https:\/\/fastalarmdistribution.com\/products\/fire-lite-rel-47k","provider":"Fast Alarm Distribution","version":"1.0","type":"link"}
