A dosing system with no way to stop itself is a liability waiting to happen — a float switch failure or empty nutrient tank can mean overdosing before anyone notices. The Bluelab External Lockout and Alarm Box solves this by connecting external switches directly to your Bluelab Pro Controller, automatically putting it into lockout mode to stop dosing the moment a problem is detected.
Wire in an external lockout sensor, such as a float switch on a reservoir or nutrient tank, and the Pro Controller halts all dosing until the issue is resolved and the system is reset — protecting your plants from system failure or low nutrient levels. The unit supports both 'normally open' and 'normally closed' switch types, and you wire in your switch options yourself for a setup tailored to your system.
Beyond lockout, the box lets you integrate your Pro Controller with an irrigation controller to automatically pause dosing during feed-out cycles, and add an external alarm, such as a horn or flashing light, for an audible alert whenever the system needs attention.
