Technician Note
Install warning signage where it remains visible to the person operating the door. A missing warning sign should be replaced, but signage does not replace required monitored safety devices.
Before Ordering
- Confirm the label or sign style matches the original requirement.
- Review the operator manual for proper warning sign placement.
- Replace faded or unreadable signs near the control station.
- Confirm required safety devices are also installed and working.
- Do not rely on signage alone for user protection.
Professional Advisory
Commercial doors should have both proper warning signage and working entrapment protection. If a door lacks safety devices, has damaged controls, or moves unexpectedly, have it inspected before normal use.
Product Q&A
Where should this warning sign be installed?
It is typically mounted near the pushbutton or control station where the door user can see it before operating the door.
Is this sign a safety device?
No. It is a warning notice only and does not replace photo eyes, sensing edges, or other required entrapment protection.
Why does the row mention 40-35246-1 and 406000?
The product record uses 40-35246-1 as the item reference while the visible product name identifies the sign as 406000. Confirm the physical stock label if exact matching is required.
When should the sign be replaced?
Replace it when it is missing, damaged, painted over, faded, or no longer readable from the control station area.
Can this be used on any door?
Use it where the LiftMaster commercial door operator instructions call for this style of pushbutton warning notice.
