The MR-Series accepts either AC or DC coil voltage from the panel or NAC, and provides multiple isolated dry-contact outputs for downstream control wiring. The clear-cover variant allows the installer to verify relay state visually during commissioning and troubleshooting without removing the enclosure.\u003c\/p\u003e\n\u003cp\u003eVerify panel\/device family compatibility before ordering.\u003c\/p\u003e","brand":"Fire-Lite","offers":[{"title":"Default Title","offer_id":52004368711973,"sku":"MR-104\/CR","price":136.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/7648\/4645\/files\/fire-lite-relays-default-title-fire-lite-mr-104-cr-relay-31896815337696.jpg?v=1771296122","url":"https:\/\/fastalarmdistribution.com\/products\/fire-lite-mr-104-cr","provider":"Fast Alarm Distribution","version":"1.0","type":"link"}
