Schlage MT11-485 Multi-Technology Mullion Card Reader

The Schlage MT11-485 is a multi-technology mullion-mount access control reader with RS-485 and OSDP communication, designed for commercial entrances and electronic access control systems. Supporting both 125 kHz proximity credentials and 13.56 MHz smart cards, it reads compatible Schlage, HID, MIFARE Classic, and MIFARE DESFire credentials. The reader operates on 5-16 VDC and features a compact 5.91 x 1.72 x 0.81-inch housing, multicolor LED indicators, and audible feedback. Its UL 294 listing and IP65 environmental rating support indoor and outdoor installations on narrow door frames and mullions.

Schlage MT11-485 Multi-Technology Mullion Access Control Reader with OSDP

The Schlage MT11-485 Multi-Technology Mullion Reader provides electronic credential identification for commercial access control systems requiring compatibility with traditional proximity cards and modern contactless smart credentials. Part of the Schlage MT Series, this reader supports both 125 kHz proximity and 13.56 MHz smart card technologies, allowing facilities to maintain supported legacy credentials while transitioning toward higher-security credential systems. Its narrow mullion-mount design accommodates aluminum storefront frames, door jambs, and other entrances with limited mounting space. The RS-485 interface supports Open Supervised Device Protocol (OSDP) communication with compatible access control controllers, providing an alternative to conventional Wiegand reader connections. The MT11-485 is suitable for office buildings, educational facilities, healthcare properties, commercial entrances, and institutional access control applications.

The MT11-485 supports ISO 14443A, ISO 14443B, and ISO 15693 contactless credential standards, accommodating compatible smart cards, proximity cards, key fobs, and mobile credentials. Supported credential families include Schlage MIFARE Classic, MIFARE DESFire EV1, EV2, and EV3, HID proximity, Schlage proximity, GE/CASI ProxLite, AWID, and LenelProx, subject to the credential format and access control system configuration. The reader also supports card serial number identification from selected third-party smart credentials and compatible Schlage NFC mobile credentials. Its multi-technology architecture enables access control administrators to accommodate different credential formats without installing separate proximity and smart card readers. The manufacturer's standard configuration provides 75-bit PIV credential output, with alternative formats available through compatible reader configuration and ordering options.

The Schlage MT11-485 operates on regulated 5-16 VDC power supplied by a compatible access control controller or approved power source. Manufacturer specifications identify an average current consumption of approximately 115 mA at 12 VDC and peak consumption of 145 mA for the RS-485 model. The reader supports RS-485 communication with OSDP-compatible controllers, allowing bidirectional exchange of reader information and control commands when properly configured. Its integrated multicolor LED provides red, green, and amber status indication, while an audible beeper supplies feedback during credential presentation and reader operation. Additional wiring provisions accommodate compatible LED control, beeper control, and tamper monitoring functions. The reader incorporates a quick-connect wiring arrangement and detachable mounting plate to simplify installation, commissioning, and service.

The MT11-485 features a compact PBT polymer enclosure measuring 5.91 inches high, 1.72 inches wide, and 0.81 inches deep, with a manufacturer-specified weight of approximately 5.7 ounces. The narrow housing is designed for surface installation on metal or nonmetal door frames and mullions, using the supplied mounting hardware and optional tamper-resistant security screw. Its IP65-rated enclosure provides protection against dust ingress and water jets, supporting indoor and outdoor installations when installed according to manufacturer instructions. The reader operates across a temperature range of -40 F to 158 F (-40 C to 70 C), accommodating exposed building entrances and other demanding environmental locations. Schlage offers the MT11 reader family in black, cool-tone gray, cream, and warm-tone brown finishes; the standard MT11-485 ordering configuration is black unless a different color suffix is specified.

The Schlage MT11-485 is designed for integration with compatible electronic access control panels and Schlage reader controller systems, including supported CTE controller configurations. Its RS-485 communication capability supports OSDP-based access control architectures, while its broad credential compatibility allows facilities to migrate from legacy proximity technology to supported smart card formats. Manufacturer documentation identifies UL 294 listing, FCC and Industry Canada certifications, CE marking, and IP65 environmental protection. Schlage also offers FIPS 201-compatible reader configurations for projects requiring approved PIV credential formats, subject to reader firmware, configuration, and controller compatibility. The reader is backed by a limited lifetime manufacturer warranty. By combining dual-frequency credential support, RS-485/OSDP communication, compact mullion mounting, and weather-resistant construction, the Schlage MT11-485 provides a versatile credential reader for new access control installations and upgrades of existing commercial security systems.
