Available Configurations

Single Interlock

Designed for systems where fire detection activates the releasing controls, allowing water to flow into the sprinkler piping after electrical detection occurs.

Double Interlock – Electric / Electric

Requires two independent fire-related events before water enters the sprinkler piping:

– Fire detection

– Sprinkler operation

Only after both conditions are met does the valve open and water enter the system.

Combines pneumatic operation with electrical fire detection, requiring both actuation events before water enters the sprinkler piping.
