The Linear Model AM/II is an extremely versatile access controller for creation of new stand-alone access control systems or for field expansion of existing systems. It offers a wide range of entry options, including a built-in radio for keyless entry and panic functions. Systems can be easily tailored by size. Each AM/II controls up to four ports, but can be networked to link as many as 32. For storage of over 65,000 input devices, names, and logged events, modular memory can be upgraded in the field.

Keyless entry and panic alarm capabilities using radio transmitters are make possible by the controller's high-gain, superheterodyne UHF receiver. Importantly, the AM/H 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. AU 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. AU 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 3 1 -bit data formats.

Which memory is right for you?



Relay: four form 'C" relays, rated at 3 amps with programmable output duration; all four can be configured for open/close; A and B can be supervised for status; C and D can be configured for control; all relay contacts have RFI, ARC, and lightning suppression.

Wiegand: Wiegand compatible signals for adding RF capability to other access control systems; 26,30, and 31-bit formats are supported.

RS232: one port for connection to a local computer printer, CRT, or modem; all communications are at 9600 baud

LCD Display: integral two-line by 24-character backlit display for local programming and transaction monitoring

LED Indicators: front panel indicators for all input and output activity for on-site troubleshooting.


RF: 318 MHz superheterodyne receiver with -90 dBm sensitivity; built-in 20 dB adjustable attenuator for fine tuning radio performance

Keypad/Reader: two sets of inputs for connecting six different keypads, card reader interfaces, or receivers

Open Request: contact closure to ground activates channel A or B relays
