AM-3: 4-Portal Access Controller (Discontinued)

The AM-3 has been replaced with the AM3Plus.

The AM-3 4-Portal Access Controller is designed for use as a primary access control device for gated communities, parking garages, 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.

The AM-3 is network ready. AM-3 units can be interconnected with Linear’s AE-1000 and AE-2000 Telephone Entry Systems through a 3-wire RS-485 network.

Two sets of Wiegand inputs are available for connection to 26, 30, or 31-bit Wiegand devices (card readers, etc.). Two sets of PBUS inputs are available for connection to Linear’s line of remote accessories.

Installation and programming are made easy by Linear’s AccessBase2000 software.
