If a reservoir runs low, a probe fouls or a pump sticks, it can keep pushing pH adjuster or nutrient concentrate into the tank, and an overdosed reservoir means burnt roots, poor nutrient uptake and stalled growth across every plant it feeds. The lockout box puts a physical check between the controller and the tank, so dosing stops when conditions are wrong rather than after the damage is done.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnect\u003c\/strong\u003e the box to your Bluelab Pro Controller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire in\u003c\/strong\u003e your float switch, irrigation controller signal or other lockout switch (normally open or normally closed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdd an alarm\u003c\/strong\u003e such as a horn or flashing light to the alarm output if you want an alert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTest\u003c\/strong\u003e by tripping the switch and confirming the Pro Controller shows lockout, then reset from the controller\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Bluelab\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e External Lockout and Alarm Box (PROEXBOX)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible with:\u003c\/strong\u003e Bluelab Pro Controller and Pro Controller Wi-Fi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e external lockout switches, normally open or normally closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e external alarm (horn or flashing light, not included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e inhibits all Pro Controller dosing until reset\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Bluelab","offers":[{"title":"Default Title","offer_id":53803794235658,"sku":"NUT-BLUE-009-01","price":57.7,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/bluelab-external-lockout-and-alarm-box-default-title-1.jpg?v=1790229359","url":"https:\/\/hydrocropshop.co.uk\/products\/bluelab-external-lockout-and-alarm-box","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
