The AM-3 4-portal Access Controller is designed for use as a primary access control device for gated communities, parking garages, Storage Unit Facilities, office buildings, apartments, dormitories, hotels/motels, commercial buildings and recreational facilities.


Housed in a lockable, plastic enclosure, the AM-3 features a 2-digit LED display, nine status indicators, four relay indicators with four relay activation pushbuttons. Three programming buttons, a reset button, and a power indicator are present. The enclosure is monitored with a magnetic tamper switch.


The system controls its four output relays by responding to various input devices that react to proximity cards, transmitters, and entry codes. The four relay output channels can be programmed to control electric door strikes, magnetic locks, door & gate operators, or barrier gates.


Access is granted or denied depending on the current user’s authorization to gain access and system settings that control groups of users or all users. Complete access control event logging, access time restriction, access location restriction, and administration functions are also available to manage the installation.
