Keyless entry and panic alarm capabilities using radio transmitters are made possible by the controller's high-gain, superheterodyne UHF receiver. Importantly, the AM / II also supports a full range of entry technologies beyond radio. Up to six accessories can be used with each controller, including: a rugged, die-cast, weatherproof keypad; an interface for Wiegand readers; a proximity reader for ultra-short range radio reception; and a remote receiver for extending radio range.

Four dry contact output relays are provided to activate door strikes, barrier gates, automatic sliding gates, and automatic doors. These outputs can also be used for alarm contact shunting, operator obstacle triggering, and alarm activation of the access devices. Two door sense inputs allow detection of propped-open doors. In addition, there are provisions for an "OPEN" request from an external source, such as a KNOX box, postal keys, or pushbutton.

Single and multi-channel transmitters are available in handheld, keychain, and pendant styles. All are MegaCode format, factory precoded with one of over 1,000,000 different codes, virtually eliminating the possibility of duplication. There are no dip switches to set. The system "learns" the specific transmitter code or block of codes, a procedure that prevents an unauthorized person from gaining access by reprogramming a transmitter. The AM / II supports 15 levels of access validation, which can be segregated by time (time of day, day of week), door restrictions, or expiration dates. All programming is stored in non-volatile EEPROM memory, with data retention in excess of 10 years, even in a power failure.

Bi-directional RS232 allows the AM / II to be linked to a modem, printer, CRT, or personal computer for system reporting and other functions. The event log feature keeps track of how many employees are on premises, which are present, and when they clock in or out. The AM / II can be programmed locally or remotely by PC and programming software, using any standard Hayes compatible (9600 baud or higher) modem.

A Wiegand interface is included for connection to other systems. It supports industry standard 26, 30, and 31-bit data formats.
