There is an internal sounder that is used to indicate key press feedback, and a bi-color LED to indicate operation. The housing has been designed to mount directly on a standard single-gang electrical box, or to most flat surfaces.
The 212 Series is designed for basic access control or code control for up to four individual devices (model dependent). These keypads are the perfect choice for controlling electric or magnetic locks, security systems, elevator control, gate controls, or other types of equipment requiring on/off or momentary control inputs.
