Cleanroom Doors, Windows and Interlock Systems
Three-Door Cleanroom Interlock System
A three-channel airlock control package for vestibules with one common entrance and two controlled exits, or other cleanroom routes requiring defined three-door sequencing.
- Three Independent Door Channels
- Branching Airlock Logic
- Configurable Door Groups
- Individual Status Indication
Product Introduction
The three-door interlock system extends standard airlock logic to a branching layout. Each door has its own closed-position input, release output and request/status station, while the controller defines which combinations must remain mutually exclusive. This supports a common entry serving two process rooms, a personnel-and-material branch, or a three-sided transfer vestibule. Channel-specific indication helps occupants identify which route is available rather than treating every locked condition as the same fault.
Key Features
Programmable grouping permits all-door mutual exclusion or selected route combinations.
Individual status outputs identify the requested door and the channel currently blocking release.
Separate held-open timers reveal which of the three doors has exceeded its permitted opening time.
Customer Product Concerns
Three-door layouts require unambiguous route logic because a simple pairwise interlock can create unintended releases or lock every exit unnecessarily.
A common entrance serves two clean rooms with different access paths.Three discrete channels apply the release rule to the selected branch instead of wiring separate controllers independently.
Users cannot tell which of two destination doors is available.Door-specific request and status indication shows each branch state locally.
Independent two-door relays create conflicting logic around the shared door.One controller evaluates all three door contacts before issuing any lock release.
Typical Applications
Branching personnel airlocksThree-sided material vestibulesShared gowning-room exitsLaboratory corridor transfer nodes
