Bluelab External Lockout With Alarm Box

This External Lockout & Alarm Box connects the Bluelab Pro Controller to external switches, like a float switch or greenhouse alarm system. Upon activation of the switches, the Bluelab Pro Controller is locked out, halting all dosing. It also features a built-in alarm which can be disabled, plus an external alarm (horn or flashing light) that can be connected. Additionally, an external lockout sensor can be connected (e.g. water flow sensor) to prevent further control and dosing. Compatible with Bluelab Pro Controller.
