Bluelab External Lockout and Alarm Box

Stop Dosing Automatically When Something Goes Wrong, Float Switch

A dosing controller cannot tell when a reservoir runs low or a nutrient tank empties, and dosing into a problem can harm plants. This add-on lets external switches, like reservoir float switches, put the Pro Controller into lockout so all dosing stops until reset. You can also connect an external alarm for an audible or visual alert.

It suits commercial systems that need fail-safe protection and integration with irrigation controllers, and home systems where a low reservoir would cause problems.

Key Features & Benefits

• External lockout — float switches or other sensors inhibit Pro Controller dosing.
• Irrigation integration — pause dosing during feed-out from an irrigation controller.
• NO and NC switches — lockout works with normally open or normally closed switches.
• External alarm output — add a horn or flashing light to the system.

Who Should Use the External Lockout and Alarm Box

Bluelab Pro Controller owners who want float-switch protection, irrigation integration or an external alarm. You wire in the switch options yourself.

Frequently Asked Questions

What does lockout mode do?

When an external switch trips, the Pro Controller enters lockout and stops all dosing until reset. This protects plants if the reservoir or a nutrient tank runs low or the system fails.

Which switches can I use?

The lockout can be activated by normally open or normally closed switches, such as float switches. You wire in the switch options yourself.

Can it pause dosing during irrigation?

Yes. You can integrate the Pro Controller with an irrigation controller so dosing pauses during feed-out.

What kind of external alarm can I add?

Bluelab lists a horn or flashing light, giving an audible or visual alert when the controller alarms.
