These systems were built around conventional and early addressable signaling line circuits, and individual interface boards handled communication, monitoring, and control functions on a modular chassis. Replacing a board rather than the full panel lets facilities extend the service life of an installed system that remains code compliant.\u003c\/p\u003e\n\u003cp\u003eVerify panel and device family compatibility before ordering.\u003c\/p\u003e","brand":"Simplex","offers":[{"title":"Default Title","offer_id":52004338663717,"sku":"677-202","price":59.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/7648\/4645\/files\/simplex-bases-default-title-simplex-677-202-4098-base-w-relay-31897142919392.jpg?v=1771296518","url":"https:\/\/fastalarmdistribution.com\/products\/simplex-677-202","provider":"Fast Alarm Distribution","version":"1.0","type":"link"}
