AWID MM-6800-GR-MP Sentinel-Prox Mullion Mount Proximity Reader
The AWID MM-6800-GR-MP is a gray Sentinel-Prox mullion mount proximity reader designed for compatible access control systems. It is commonly installed at pedestrian gates, storefront entrances, office doors, equipment rooms, commercial buildings, access-control pedestals, and controlled entry points where a slim reader is needed on a door frame, window mullion, wall, cabinet, or gate post.
This reader is part of AWID's MM-6800 Sentinel-Prox reader family and is built for 125 kHz proximity credential applications. When a compatible card, key tag, hang tag, or adhesive wafer is presented to the reader, the reader sends the credential data to the connected access control panel. The panel then decides whether to unlock a door, release an electric strike, trigger a magnetic lock relay, activate a gate relay, or deny access based on the programmed credential record.
The MM-6800 is a higher read-range mullion reader compared with many compact frame-style prox readers. It is commonly listed with a 6 to 8 inch read range, depending on the credential type, mounting surface, voltage, wiring quality, and site conditions. Its metal-compensated housing helps reduce read-range loss when mounted on a metal mullion, metal door frame, access pedestal, or similar mounting surface.
The MM-6800-GR-MP version is commonly listed as a gray AWID-logo mullion reader with Wiegand and RS-232 interfaces. The "MP" version is often associated with multi-protocol or HID-format applications in supplier listings, but credential compatibility should still be verified before ordering. A reader can physically read a credential and still fail to grant access if the facility code, bit format, card number range, or access control panel programming does not match the system.
This is a reader only. It does not store users by itself, unlock a door by itself, power a lock by itself, or replace the access control panel. The reader must be connected to a compatible access controller that provides proper DC power, accepts the reader data format, and controls the lock, gate, or door relay.

Technician Note
When replacing an access control reader, match the exact reader model, credential technology, data format, power requirement, wire functions, and controller programming. A reader can power up and beep but still not grant access if the card format, facility code, bit length, or controller software setup does not match the existing system.
The MM-6800-GR-MP should be connected to a compatible access control panel, not directly to a lock or gate motor circuit. The reader sends credential data to the controller. The controller is responsible for deciding access and switching the proper relay for the door, gate, strike, maglock, or request-to-enter device.
For gate or outdoor reader installations, check the cable route, shield grounding, voltage at the reader, metal mounting surface, weather exposure, and distance from electrical noise sources. Gate operator motor wiring, strike power wiring, high-voltage conduit, fluorescent lighting, and long unshielded cable runs can reduce reader performance or cause intermittent reads.
Before Ordering, Confirm

- The reader port or power supply provides regulated 5 to 12V DC power.
- The existing cable has the required conductors for power, ground, Data-0, Data-1, and any LED, beeper, hold, or RS-232 functions being used.
- The mounting location can support the 6 inch tall mullion reader housing.
- The controller software can enroll and manage the cards that will be used with this reader.
- The reader is being connected to an access controller, not directly to high-voltage lock power or gate motor wiring.
Professional Advisory
This is a low-voltage access control reader, but it is often part of a larger system that controls gates, electric strikes, magnetic locks, request-to-exit devices, fire/life-safety release circuits, and door hardware. Installation should be handled by a qualified access control or gate technician when the controller wiring, credential format, or lock/gate relay design is not clearly understood.
Do not connect this reader directly to high-voltage wiring, lock power beyond its rating, or gate operator motor circuits. Do not use reader wiring as a substitute for proper lock power wiring, relay isolation, safety circuits, or code-required release hardware.
For gate applications, the reader may be used to request entry through the access control system, but it must not bypass required gate safety devices. Photo eyes, safety edges, loop detectors, monitored entrapment protection, and other required safety equipment must remain installed and working.
