SES OPTDF2 Designer Frame for TEC / CAT2 and CAT4 HF Telephone Entry Units
The SES OPTDF2 Designer Frame is a finish trim accessory used with select Select Engineered Systems telephone entry panels. It is mainly a cosmetic and mounting-finish part, not an electronic repair board or functional upgrade. On the right application, it gives the TEC or CAT entry station a cleaner architectural border and can help cover the transition between the telephone entry panel and the wall, column, pedestal, or enclosure opening.
This part is commonly searched for by facilities maintaining older SES CAT2 HF, CAT4 HF, TEC2, or TEC4 style entry systems. Because SES used different cabinet and faceplate styles across the TEC, CAT, and hands-free families, the frame should be matched to the exact telephone entry model and opening before ordering. It should not be used to guess-fit a different size telephone entry panel.

Technician Note
For older SES telephone entry panels, the most common ordering mistake is confusing a trim frame with a door, faceplate, or internal option card. Match the frame by the SES option number and cabinet style.
Before Ordering Checklist
- Confirm the entry system is a compatible SES TEC/CAT2 or CAT4 HF style unit.
- Verify the existing enclosure and mounting style.
- Compare the required designer frame part number to OPTDF2.
- Do not order this part to repair electronics or keypad operation.
- Check whether mounting screws or other hardware are included by your supplier.
Professional Advisory
Installation should not require high-voltage electrical work, but the telephone entry enclosure should be secured properly and weather sealing should not be compromised.
Important Ordering Warnings
If the existing panel has been modified, painted, replaced, or mounted in a custom column, verify the opening dimensions before ordering a trim frame.
Product Questions and Answers
Is OPTDF2 an electronic repair part?
No. OPTDF2 is a designer frame or trim accessory. It does not repair the keypad, display, board, phone line, relay output, or card-reader function.
Will this frame fit every SES telephone entry unit?
No. It is commonly associated with select TEC/CAT2 and CAT4 HF applications. Match the original model and enclosure before ordering.
Can OPTDF2 replace OPTDF1?
Do not assume that. OPTDF1 and OPTDF2 are related designer-frame references for different SES applications and should be matched by the original parts list.
Does this include the telephone entry unit?
No. This listing is for the frame accessory only unless the supplier package specifically states otherwise.
What should I check before ordering?
Check the SES model number, faceplate style, mounting style, and opening size. A similar-looking SES frame may not fit the same enclosure.
