SES RPDISP4L , 4 LINE DISPLAY ASSY (7.5x3.5") W/HARDWARE, CAT4/TEC4s **
The SES RPDISP4L is the large-format 4-line display assembly used in compatible SES CAT4 and TEC4 telephone entry systems. This display allows visitors to view multiple directory names or prompts at one time, so readability is important for apartment, condominium, commercial, and gated-entry applications. When an older screen becomes faded, develops missing characters, or is damaged behind the Lexan window, replacing the correct display assembly can restore normal visibility without replacing the complete telephone entry unit. Because SES has several similar display families, this part must be matched by the panel model and display opening. It should not be confused with RPDISP4LT1 for TEC1M, RPDISP4L-OLDLG for older framed large-display units, or TEC1A-specific display and window parts.

Technician Note
Technician Note: match the existing Select Engineered Systems part number, panel series, line count, connector style, and physical opening before ordering. Similar SES parts can look alike but may not fit the same cabinet or display assembly.
Before Ordering
- Confirm the installed SES model family and line count.
- Compare the existing part number or old component label.
- Check display/window size, screw pattern, gasket shape, and harness connector.
- Look for water damage, corrosion, cracked cables, or modified wiring inside the panel.
- Do not substitute a similar 2-line, 4-line, 10-line, TEC1M, TEC1A, or legacy part unless the SES parts diagram confirms the match.
Professional Advisory
SES telephone entry display and window service parts should be installed with power removed from the unit. If the entry system has water damage, corrosion, damaged wiring, or intermittent display operation after parts replacement, have the unit checked by a qualified access-control technician.
Product Questions and Answers
Is RPDISP4L the same as RPDISP4LT1?
No. RPDISP4L is commonly tied to CAT4 and TEC4 style panels, while RPDISP4LT1 is a smaller 4-line display assembly for TEC1M applications.
Can this replace a 2-line or 10-line display?
No. The line count, display opening, and harness style must match the installed panel.
Does this include the Lexan window?
This row is for the display assembly with hardware. The matching Lexan window is typically a separate service part such as RPWINDOW4L.
Why is my display still blank after replacement?
A blank screen can also come from a power issue, failed controller board, damaged harness, or corrosion inside the panel.
What should I compare before ordering?
Compare the panel model, old display part number, physical display size, plug-in harness, and mounting hardware.
