Linked entrance and exit.
Clean room interlocking doors coordinate entrance and exit permissions. Confirm the door states required before the next opening is permitted.

Linked openings.
A clearly defined sequence.
A cleanroom door interlock system coordinates which linked door may open and when. Define the opening order and the door-state feedback required before the next movement.
DOOR SEQUENCING
How a cleanroom door
interlock system works.
Select a stage to follow a two-door example. The final permission rules and completion conditions are agreed for the project.

INTERLOCK INSTALLATIONS
Linked doors.
Different arrangements.
Two examples of door interlocking. Each starts with a defined group and an agreed opening order.
One defined door group.
Mark every linked opening and define the allowed order, including requests that arrive together. This photograph shows part of a three-door arrangement.
CONFIRM THE INTERLOCK CONDITIONS
Define the rule
for every request.
These four points define the interlock brief: the door group, verified states, interrupted cycles and release conditions.
Linked doors and request priority
Identify every door in the group. Agree which request takes priority when two openings are requested together.
Confirmed door states
Specify the position feedback needed to permit the next movement. Review it alongside the selected door’s passage protection.
Interrupted movement or signal loss
Define the response to missing feedback or a door that does not reach its expected state. Include operator indication and recovery checks.
Release and restart
Agree emergency release, the response to a power interruption and the reset conditions before normal operation resumes.
DISCUSS YOUR INTERLOCK
Plan your door sequence.
Send the linked door positions and the required opening order. We’ll review the interlock conditions with you.
