Alarm.com Mullion Reader
The ADC-AC-ET10 is a single-gang smart card reader designed for access-control systems under Alarm.com or compatible security ecosystems. It supports multiple credential types, including legacy 125 kHz Proximity cards/fobs and 13.56 MHz MIFARE DESFire credentials. The reader accepts an input power range of 5–16 V DC, making it compatible with most standard access control power supplies. Its design supports communication protocols such as Wiegand or OSDP (if supported by the controller), enabling flexibility in integration. The unit is built for indoor or protected-environment installation and provides a cost-effective access entry option for residential, office, or light-commercial applications.

The ADC-AC-ET10 is a suitable choice when you want a simple and economical access-control solution — particularly for single doors, small offices, or residential properties. Because it supports both older proximity cards and more secure MIFARE DESFire credentials, it offers flexibility if you plan to upgrade later. Its compatibility with standard power supplies and common communication protocols makes installation straightforward without specialized wiring or hardware. While it may not include advanced features found in higher-end readers (such as BLE/mobile credential support or tamper detection), its simplicity and reliability make it adequate for basic access-control needs. Use-cases like gated entries, small offices, or controlled-access rooms are where the ET10 performs well.
