SES T1HF50M, TEC1 HF 50CAP 4 LINES DISPLAY
The SES T1HF50M is a TEC1M hands-free telephone entry control system from Select Engineered Systems. It is designed for smaller properties that need basic telephone entry with 50 phone/user capacity and a 4-line LCD directory display. The TEC1M format is useful when the site wants more directory information visible on screen than the standard 2-line TEC1 display provides.
This model is commonly listed as the TEC1 HF 50 capacity 4-line display unit. In the SES TEC1 Series, the standard TEC1 models use a 2-line display, while TEC1M models use the 4-line display format. SES describes the TEC1 Series as basic telephone entry with multiple capacities to match the site requirements, including 50, 125, 250, 500, and 995.
The T1HF50M should be treated as a telephone entry control system, not as a gate opener, gate operator control board, card reader, or safety device. It provides the visitor calling, directory display, and relay-command side of the system. The gate operator, door hardware, phone service, power, pedestal, mounting hardware, communication accessories, and site wiring must still be selected and verified separately.
What This Unit Does
The SES T1HF50M allows visitors to use the front-panel directory and keypad to locate a resident, tenant, office, department, or authorized user, then place a call from the entry point. Once the call connects, the resident or authorized user can speak with the visitor and grant access using the programmed touch-tone command, depending on how the system is wired and configured.
The 4-line TEC1M display provides a larger directory view than the standard 2-line TEC1 version. This can make the entry station easier to use on smaller properties where the user count is low, but a larger display is still preferred for readability and visitor convenience. The two standard relay outputs can be used for gate or door release control when connected to compatible equipment through the correct dry-contact input or relay interface.
Compatible With
The SES T1HF50M is intended for select SES TEC1M Series telephone entry control applications where 50 phone/user capacity and a 4-line LCD display are required. Compatibility depends on communication method, relay wiring, mounting style, power requirements, programming method, access-control hardware, and any optional communication equipment used on the site.
- Select Engineered Systems TEC1M telephone entry applications
- TEC1 Series installations requiring 50 phone/user capacity
- Applications requiring the 4-line TEC1M display format

Do not assume that a T1HF50M will directly replace every older SES, TEC, CAT, DoorKing, Linear, LiftMaster, Aiphone, or other telephone entry unit without checking the wiring, mounting, communication, relay, directory, display format, and programming requirements. Match the model, capacity, display type, and options before ordering.
Not Intended For
- Gate opener motor replacement
- Swing gate actuator replacement
- Slide gate operator control board replacement
- Barrier gate operator repair
- Emergency phone or SAT emergency tower applications
- CAT Series card-access systems where CAT expansion features are required
- TEC 10 applications requiring a 10-line display

- Standard 2-line TEC1 installations where T1HF50 is the intended model
- Direct replacement of a non-SES telephone entry system without confirming wiring, mounting, relay, programming, and communication compatibility
Important Ordering Warnings
- Confirm the exact version: T1HF50M is the 4-line non-card-access TEC1M 50-capacity model. Do not confuse it with T1HF50, T1HF50CA, or T1HF50MCA.
- Confirm the display requirement: This is the 4-line TEC1M display version. If the site only needs a 2-line display, review T1HF50. If the site needs a 10-line display, review the T10HF series.
- Confirm capacity: This model is commonly listed with 50 phone/user capacity. If the property may grow, review T1HF125M, T1HF250M, T1HF500M, or T1HF995M where available.
- Card access may require a different model: The CA models are the card-access capable TEC1 versions and include modem and basic software. Do not assume the T1HF50M includes card access unless the current supplier package confirms it.
- Confirm communication method: Telephone entry systems may require a phone line, VoIP/SIP adapter, cellular interface, modem option, serial option, network option, or other communication equipment depending on the site.
- This is not the gate operator: The T1HF50M sends the access command. The gate operator or door-control device must be installed, wired, and operating correctly on its own.

Technician Note
The T1HF50M is the 4-line non-card-access version of the TEC1 50-capacity hands-free unit. It should be selected when the site needs basic telephone entry and a larger 4-line TEC1 display, but does not need card access capability. If card access is needed, compare the T1HF50CA or T1HF50MCA before ordering.
For replacement jobs, confirm the existing TEC1 model, display style, capacity, phone-line setup, programming method, relay wiring, mounting style, and any installed communication accessories. A TEC1 unit with the same capacity may still differ by display type, card access capability, modem/software options, enclosure style, or communication setup.
Before Ordering, Confirm
- Confirm the needed part number is T1HF50M.
- Confirm the site requires a TEC1M hands-free telephone entry system with a 4-line display.
- Confirm the property needs 50 phone/user capacity.
- Confirm whether the standard T1HF50, card-capable T1HF50CA, or 4-line card-capable T1HF50MCA would be a better match.
- Confirm whether card access is required. If yes, use the proper CA or MCA model instead of assuming T1HF50M includes card access.
- Confirm communication method, such as phone line, VoIP/SIP interface, cellular interface, modem, serial connection, network interface, or other approved setup.
- Confirm whether keypad programming, modem programming, remote programming, or accessory-based programming is required.
- Confirm the number of entrances or relays required and how the two standard relays will be used.
- Confirm the gate operator or door-control device has a compatible dry-contact input for access commands.
- Confirm mounting style, pedestal requirements, weather exposure, enclosure style, and site conditions.
- Confirm power requirements and whether the transformer or power supply is included with the current package.
- Confirm grounding, surge protection, communication wiring, and low-voltage wiring requirements.
- Confirm current package contents, including keys, manuals, mounting hardware, software, modem options, transformer, and accessories.
Professional Advisory
Telephone entry installation requires proper low-voltage wiring, telephone or communication wiring, relay wiring, grounding, surge protection, programming, directory setup, and gate or door hardware coordination. A qualified access-control technician should handle the installation when the site includes remote programming, VoIP/SIP conversion, cellular conversion, commercial door hardware, long outdoor cable runs, or an existing database transfer.
Do not connect telephone entry equipment in a way that bypasses gate safety devices, monitored entrapment protection, fire access requirements, emergency release requirements, or door life-safety hardware. The T1HF50M should only command a properly installed gate operator or door-control device through the correct relay or input interface.
