If a switch is triggered — for example, a float switch detecting low nutrient levels or a reservoir fault — the Pro Controller immediately enters lockout mode and halts all dosing until the condition is resolved and the system is reset. An external alarm output allows you to add a horn or flashing light for audible\/visual notification.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible With\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBluelab Pro Controller\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIdeal For\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHydroponics and aquaponics systems using the Bluelab Pro Controller\u003c\/li\u003e\n\u003cli\u003eGrowers integrating float switches or level sensors for reservoir safety\u003c\/li\u003e\n\u003cli\u003eCommercial and hobby grows requiring automated overdose protection\u003c\/li\u003e\n\u003cli\u003eSystems with irrigation controllers requiring dosing pause during feed-out\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBluelab External Lockout \u0026amp; Alarm Box\u003c\/li\u003e\n\u003cli\u003eUser Manual\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bluelab","offers":[{"title":"Default Title","offer_id":44174114259031,"sku":"PROEXBOX","price":79.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1555\/0581\/files\/PROEXBOX_image_web.webp?v=1786979700","url":"https:\/\/getultimatenow.com\/products\/bluelab-external-lockout-and-alarm-box","provider":"Get Ultimate Now ","version":"1.0","type":"link"}
