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,
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
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.
