Permanent LED Message Centers in Greater St. Louis
A permanent electronic message center, also called an EMC or LED message center, displays changing information at a fixed property. Businesses and churches may use one for announcements while keeping a permanent name or logo elsewhere in the sign design.

Design the message for the viewing distance
Display dimensions, pixel pitch and the distance from viewers influence how much information can be read. A small display crowded with detailed copy may be less useful than a concise message designed for the approach. Discuss the intended audience and typical content before selecting a display.
Review display rules before the final design
Local requirements may address brightness, operating hours, message changes, dwell time and animation. Rules vary by jurisdiction and site. Do not assume that video or a particular display size is allowed. Identify the property address and applicable authority before committing to a content or permit claim.
Consider the whole sign system
A message center can be part of a monument or elevated sign arrangement, subject to the specific design and approvals. The proposal should define the display, supporting sign identity, control/connectivity arrangements and complete project scope. These displays are designed for permanent property identification and announcements.
Planning a sign in the St. Louis region
Share the exact project address so the applicable jurisdiction and site requirements can be identified. Landlord or association approval and municipal sign approval are separate considerations. No approval, sign dimension or installation date is assumed before the actual project is reviewed.
Questions before you request a quote
Can a church use an electronic message center?
A permanent message center may suit announcements at a church property, where local rules permit it. The size, location and display behavior need site-specific review.
Will it replace our permanent business name?
Not necessarily. Permanent identification and changing messages have different jobs. A combined design can keep the name recognizable while announcements change.
Talk through your complete sign project
Send your address, photographs, artwork if available and any landlord or association criteria. Explain whether you are opening, relocating, rebranding or replacing a sign. S.O.I. can discuss the appropriate next information for your proposal.
