Use the External Lockout and Alarm Box to connect external audible or visual alarms to signal whenever your Bluelab Pro Controller enters an alarm state.

You can connect a variety of external switches to put the Bluelab Pro Controller into lockout mode to inhibiting dosing. External switches could be float switches on reservoirs or nutrient stock tanks to stop dosing when a low nutrient level is reached.
