IEI 212i Indoor Flush-Mount Keypad

The IEI 212i is a standalone indoor access control keypad designed for single-door, flush-mounted installations. Supporting up to 120 user codes, four independently programmable outputs, and four timers, it provides PIN-based access control without requiring a separate controller. The keypad operates on 12-24 VAC/VDC and features a 5A Form C relay, three 50 mA auxiliary outputs, and three status LEDs. Its compact design fits standard single-gang electrical boxes in offices, commercial buildings, and controlled-access rooms.

IEI 212i Door-Gard Indoor Flush-Mount Access Control Keypad, 120 Users

The IEI 212i Door-Gard is a standalone electronic access control keypad manufactured under the Linear product family for indoor, single-door security applications. It stores up to 120 programmable user codes containing 1-6 digits, allowing authorized users to unlock connected doors through PIN entry. The keypad includes four independent outputs and four programmable timers for controlling compatible electric locks, auxiliary devices, and access control functions. Programming is performed directly from the keypad without a separate computer or programming device. Its flush-mounted, single-gang design supports installation at office entrances, interior doors, equipment rooms, and other low-traffic access points.

The 212i features one Form C (SPDT) relay rated at 5A at 24 VDC, with a 10A surge rating, for controlling compatible electric strikes, electromagnetic locks, and other access control hardware. Three additional 50 mA negative-voltage outputs support auxiliary functions, while the optional IEI 293 relay expansion board converts those outputs into independent Form C relay contacts. The keypad also provides a remote request-to-exit input for connection to compatible exit buttons or triggering devices. User codes can be assigned to specific outputs, with programmable activation times supporting momentary or maintained operation. Three integrated LEDs display operating status and provide visual confirmation during PIN entry and programming.

The IEI 212i operates on 12-24 VAC or VDC power with automatic voltage selection and no manual voltage jumper adjustment. Typical current consumption is 8 mA at 12 VDC or 16 mA at 24 VDC, increasing to 35 mA and 45 mA respectively when the main relay is energized. The manufacturer recommends a filtered, regulated power supply for stable operation. Internal nonvolatile memory retains programmed access codes during power interruptions, while front-panel programming allows administrators to add or remove users, modify access codes, and configure output functions. The keypad includes a remote triggering connection and supports integration with compatible door release equipment without requiring a network connection.

The 212i indoor keypad measures 2.75 inches wide x 4.50 inches high x 1.30 inches deep and mounts to most standard single-gang electrical back boxes. Its operating temperature range is -20 F to 130 F (-28 C to 54 C), with installation restricted to indoor environments. The package includes wiring harnesses, standard and security mounting screws, and a transient voltage suppressor for protecting the keypad when connected to inductive locking devices. The optional 293 relay module increases installation depth to approximately 1.68 inches. Manufacturer documentation specifies a 24-month limited warranty. Designed for standalone PIN-based entry, the IEI 212i provides programmable access control for compatible electrically operated doors without requiring a separate access control panel.
