Select Entry Systems SG2CL Cellular Select Gate Entry System
The Select Entry Systems SG2CL is a Cellular Select Gate entry system designed for residential and light commercial gate access-control applications. It gives a property owner, manager, or authorized user several ways to control the gate without relying on a traditional landline at the gate location.
The SG2CL can be controlled by SMS text, the Select Gate Mobile Control app, keypad entry, remote touch tones, and compatible card readers connected through the built-in 26-bit Wiegand input. It is commonly used for driveway gates, private road entrances, gated properties, small commercial entries, service gates, employee entrances, and other controlled access points where a cellular gate entry system is preferred over a hardwired phone-line system.
This model is part of the Cellular Select Gate Series. It is the SG2CL version, also commonly described as the Select Gate 2 cellular entry control. It should be kept separate from standard non-cellular Select Gate models and from SG3DMCL or SG3DMRCL models, which use a different cabinet layout and may include or support different receiver options.
The SG2CL supports up to 10 phone numbers that can be dialed from the keypad, along with up to 1000 Caller ID recognizable phone numbers. It can forward calls to up to 3 rollover phone numbers in the programmed sequence, helping visitors reach the correct person if the first number does not answer.
For access credentials, the SG2CL supports 2000 mix-and-match PINs and cards depending on how the system is configured. PIN code range is listed from 0001 to 9999, card number range from 00001 to 65534, and site code range from 001 to 255. The built-in 26-bit Wiegand input allows a compatible card reader to be added when card or credential access is needed.
The SG2CL includes two Form C dry-contact relay outputs for gate or door control. These relays are used to send access commands to a compatible gate operator, door controller, or access-control input. The SG2CL does not power the gate operator and does not replace the gate operator control board. It sends the command; the gate operator still performs the actual open, close, and safety functions.
This system also supports useful gate-control commands such as latch open and hold open for 1 hour through SMS text, the mobile app, or remote touch tones. It includes a REX input, gate-position sense input, SMS signal-strength verification, LED lighting, and a blue backlit keypad for better visibility at night.
Cellular service must be planned before installation. The site needs reliable cellular signal at the exact mounting location, not just near the house, office, or driveway. The cellular device also requires an active SIM/service plan with the required voice and SMS services for normal operation. Always confirm the current carrier, SIM activation, coverage, and service-plan requirements before installation.
Important: The Cellular Select Gate is not an emergency telephone and cannot be used for 911 calls. Emergency access, fire department access, Knox-style access, manual release, monitored safety devices, loop detectors, photo eyes, and safety edges must be handled separately according to the gate system and local requirements.

Compatible With
The Select Entry Systems SG2CL can be used with many gate operators and access-control devices that accept a compatible dry-contact relay command. Final compatibility depends on the gate operator wiring diagram, relay input requirements, power source, cellular service, Wiegand reader requirements, and site layout.
- Residential swing gate operators with compatible open, radio, push-button, or access-control inputs
- Residential slide gate operators with compatible open, radio, push-button, or access-control inputs
- Light commercial swing gate operators with compatible dry-contact access-control inputs
- Light commercial slide gate operators with compatible dry-contact access-control inputs
- Select barrier gate operators where relay-based entry control is appropriate

Technician Note
The SG2CL is a cellular gate entry system, not a large multi-tenant directory system. It is a good choice when the job needs keypad access, phone-number calling, Caller ID access, SMS text control, app control, remote touch-tone control, and optional 26-bit Wiegand card-reader access in a compact Select Gate package.
Before selling this unit, confirm cellular signal at the exact gate location. Signal at the office, house, parking area, or technician phone does not always mean the mounted call box location has reliable service. Metal posts, masonry columns, long driveways, landscaping, and weak carrier coverage can affect performance.
Power wording should be reviewed carefully. Older listings may show 12-24V AC/DC or reference an AC transformer. Current product-sheet wording for SG2CL lists 12-24V DC only with a 12V 2A DC transformer included. Verify the current unit and installation manual before wiring or publishing specifications.
The SG2CL includes two Form C dry-contact relay outputs. Wire those relays only to compatible low-voltage access-control inputs on the gate operator or door controller. Do not use the relays to switch high-voltage operator power or bypass the gate operator control board.
This device cannot be used for 911 calls. It should not be sold as an emergency phone, fire department phone, elevator phone, or life-safety phone. Emergency access and fire access must be handled separately according to the property, local authority, and gate system requirements.
Before Ordering, Confirm
- The required model is SG2CL.
- The store part number is SES-SG2CL or the matching internal SKU used for this product.
- The customer needs the SG2CL Cellular Select Gate, not SG3DMCL, SG3DMRCL, SG2C, or another Select Gate model.
- The site has reliable cellular signal at the exact mounting location.
- The SIM card and cellular service plan requirements are understood before installation.
- The connected gate operator or door controller accepts a dry-contact relay input.
- The customer needs no more than 10 dialed keypad phone numbers.
- The customer needs no more than 1000 Caller ID recognizable phone numbers.
- The PIN/card capacity and numbering requirements match the site.
- Any card reader being added is compatible with the built-in 26-bit Wiegand input.
- The mounting method is selected, such as surface mount or pedestal mount.
- The power source matches the current 12-24V DC requirement.
- The customer understands the device cannot be used for 911 calls.
- The gate operator safety devices, emergency access, fire access, and manual release equipment are handled separately.
Professional Advisory
The Select Entry Systems SG2CL should be installed by a qualified gate, access-control, or low-voltage technician when relay wiring, DC power wiring, Wiegand reader wiring, cellular activation, programming, or gate operator input wiring is not clearly understood.
Do not use the SG2CL to bypass gate safety devices, monitored photo eyes, safety edges, loop detectors, stop circuits, emergency access devices, or required entrapment protection. The SG2CL provides access-control commands only. The gate operator must still be installed, wired, and tested as a safe automatic gate system.
After installation, test every access method being used. Confirm keypad dialing, rollover numbers, SMS commands, SGMC app control, touch-tone control, Caller ID access, PINs, card-reader access, relay operation, REX input, gate-position sense, cellular signal, emergency access, and all gate safety-device operation before turning the system over to the customer.
