SES TEC1A Premium Telephone Entry System Details
The SES T1A4L250PRM is a Select Engineered Systems TEC1A Premium telephone entry system with a 4-line LCD directory display and 250 phone capacity. It is designed for controlled entry applications where visitors call residents, tenants, employees, or authorized users from the entry panel, and access can be released through the system when properly connected to a compatible gate operator, door strike, magnetic lock, or access-control device.
This Premium configuration includes the expanded feature package commonly listed with a 2-door reader board, NIC, modem, clock/calendar, serial interface, and MUI multi-user interface. That separates it from the Basic and Deluxe versions. The Basic model does not include the same communication package, and the Deluxe model does not provide the same Premium reader/NIC feature set.
The T1A4L250PRM is a practical fit for access-control locations that need a 4-line TEC1A telephone entry panel with mid-range directory capacity and Premium communication and reader-control capability. It is commonly used for gated communities, apartment properties, condominium entries, commercial buildings, tenant entry points, parking areas, office entrances, and secured pedestrian or vehicle access points where telephone entry, reader control, and communication flexibility are needed.

Not Intended For
- Sites that require the 2-line TEC1A display version unless the correct T1A2L model is ordered.
- Sites that require 50, 125, 500, or 1000 phone capacity unless the correct TEC1A capacity model is ordered.

- Sites that require the Deluxe package without the Premium reader/NIC configuration unless the correct DLX model is preferred.
- Sites requiring a cellular-equipped Premium model unless the correct PRMCL model is ordered.
- Direct replacement of older SES TEC1, TEC1C, TEC1CA, TEC2, CAT, or other SES systems without confirming wiring, mounting, programming, options, and required features.
- Applications requiring a monitored UL325 safety device. This is an access-control / telephone entry system, not a monitored gate safety sensor.
Important Ordering Warnings
- Confirm the exact SES part number before ordering. T1A4L250PRM identifies a TEC1A, 4-line LCD, 250-capacity, Premium model.
- Do not confuse this model with T1A4L250BSK, T1A4L250DLX, T1A4L250PRMCL, T1A2L250PRM, or other similar TEC1A part numbers.
- Verify whether the site needs Basic, Deluxe, Premium, or Premium Cellular features. Premium models include the expanded reader/NIC feature package, while Premium Cellular models are a separate configuration.
- Confirm reader wiring, door control wiring, relay use, network/NIC requirements, modem requirements, serial connection, MUI requirements, and programming method before installation.
- Confirm the required mounting method. Weather hoods, semi-flush rings, sleeves, pedestals, adapters, and mounting plates may be separate accessories depending on the installation.

Technician Note
Match this unit by the full SES model number and Premium feature package. T1A4L250PRM identifies the TEC1A series, 4-line LCD display, 250 phone capacity, 1000 card capacity, and Premium package with 2-door reader board, NIC, modem, clock/calendar, serial, and MUI. Similar TEC1A units may look alike from the front, but can differ by display type, capacity, reader board support, NIC/Ethernet capability, modem support, serial support, MUI support, cellular configuration, and included option boards.
Do not treat Basic, Deluxe, Premium, and Premium Cellular versions as interchangeable without checking the job requirements. A site that requires reader board control or NIC/network capability may need a Premium model. A site requiring built-in cellular configuration may need the PRMCL version instead of this PRM model.

Professional Advisory
Telephone entry systems connect to access-control wiring, reader wiring, relay circuits, power, phone lines, network interfaces, communication ports, and sometimes software programming equipment. Improper wiring or incorrect configuration can damage the entry system, gate operator, lock hardware, reader equipment, or related access-control components. If the existing wiring, voltage, relay circuit, phone line, reader wiring, NIC/network setup, modem setup, serial wiring, MUI wiring, or programming requirements are uncertain, installation and replacement should be handled by a qualified gate or access-control technician.
This product is an access-control telephone entry system. It does not replace required monitored gate safety devices, photo eyes, edge sensors, entrapment protection, or other safety equipment required for an automatic gate system.
