Parakey Slim is a door controller that can operate electromechanical locks, alarms, elevators, and more, as well as enhance existing access control systems. Slim also has a door button input and future support for OSDP.

Parakey Slim is fully offline and communicates with the Parakey app via Bluetooth. Since the device uses radio waves for communication, it should be installed close to the door, gate, or entrance you want to open. Read more about Slim placement for optimal range.
