Introduction

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

The AM-3 can be powered from a 12-24 Volt AC or DC source. DC
power can be obtained from the access device or AC power from
a separate power transformer. The system supports and charges
a 12-volt backup battery for operation during power outage. Low
battery detection circuitry monitors the backup battery’s condition.
The EEPROM memory retains all entry codes and programming,
even without power.

Operation

In a typical installation, the unit’s memory would be programmed
with each resident’s name and entry code number. Ariving
visitors would use a remote keypad to enter their entry code. Also
proximity receivers, swipe card readers, and other remote devices
can be used with the system.

Block coded MegaCode® transmitters can be used to gain access
through a remote radio receiver connected to the AM-3 PBUS.
Each transmitter can be individually suspended or re-activated.

The system’s clock/calendar can control access based on specifi c
times and dates. Automatic relay activation can be scheduled.
Access can be restricted to certain times and dates. Holiday
access can be scheduled.

The system’s event log records system activity for future
reference.

Feature Overview

Relay Outputs

Four 3-amp dry contact relay outputs are provided to activate four access
devices, such as door strikes, magnetic locks, automatic doors, barrier gates,
and automatic sliding gates. The relay outputs can also be used for alarm
contact shunting, operator obstacle triggering, and alarm activation. Each of
the four relays can also be manually activated from buttons on the front of the
AM-3. LED indicators display the status of each relay.

Request-to-Exit Inputs

Each relay channel has a request-to-exit input. These inputs are supplied for
hardwire activation of the access devices. Typically a request-to-exit input is
wired to a pushbutton inside of the access controlled area. When a person
desires to exit, pressing the pushbutton will activate the output relay channel
and trigger the access device. A loop detector for automatic gate operation
can be connected to a request-to-exit input.

Sensing Inputs

The sensing inputs connect to door switches that monitor whether the
controlled door is open or closed. The sensing inputs may alternately be
programmed as “access inhibit” inputs for use with an external timer or
service switch.

Optional Modem

A modular connector is provided for telephone line connection to the unit’s
optional 33.6K baud modem. The system can be accessed remotely for
programming and control over the standard telephone system using a
personal computer with a modem. For system backup, a computer connected
through the modem can store and retrieve the AM-3’s memory data.

RS-232 Communications Port

A modular connector is provided for the bi-directional 38.4K baud RS-232
port. The AM-3’s RS-232 port connects to a personal computer’s COM port.
System programming can be performed locally with a computer connected to
the RS-232 port.

Obstacle Detection

Linear’s Model MGT safety edge transmitter is compatible with the AM-3. The
MGT detects and transmits obstacle events to the AM-3.

Programming Memory

The AM-3’s fl ash memory retains all entry codes, transmitter information, card
access, and programming, even without power.

Computer Programming

The system programming can be accessed using a computer and modem
using Linear’s AccessBase2000 custom software.

Battery Backup

The system supports a 12-volt battery backup for operation during power
outage. The system will charge the backup battery when AC power is
present.

Network Support

Multiple AM-3, AE-1000, & AE-2000 units can be networked together allowing
information sharing between the units. Networked units are interconnected
with a three-wire cable. A common event log is retained for all of the
networked units.

Linear PBUS Ports

Two 6-wire Linear PBUS input/output ports are available to connect to several
accessories (keypads, proximity readers, remote receivers).

PBUS Accessories

Several compatible accessories are available to connect to the AM-3’s two 6-wire
communications “PBUS” inputs. Up to six PBUS accessories can be used with
each AM-3 unit.

AM-RRR Remote Radio Receiver

For wireless transmitters, connect the Model AM­RRR high-gain superheterodyne UHF receiver. The
receiver is housed in a weather-resistant enclosure
and can be mounted indoors or outdoors. Gaskets
and a weather-tight wiring strain relief seal the unit

AM-RRR

from the elements.

AM-RPR Remote Proximity Receiver

The Model AM-RPR functions as a remote device
that supplies localized radio reception for the AM-3
In a typical installation, the AM-RPR would be
mounted in a plastic single-gang electrical box next
to the controlled opening. When the user requires
access, their transmitter must be activated within

AM-RPR

three inches of the AM-RPR faceplate.

AM-KP Exterior Keypad

The Model AM-KP is housed in a rugged cast
aluminum enclosure designed for exterior
installations. The die-cast keys have bright,
easy-to-read yellow graphics. The keypad can
be mounted to a pedestal or directly to a wall.
A keylock secures the keypad to the mounting

AM-KP

backplate.

AM-KPI Interior Keypad

The Model AM-KPI keypad is housed in a rugged,
plastic enclosure designed to be mounted indoors
in a standard single-gang electrical box. Tamper
resistant screws secure the keypad to its mounting
plate. The die-cast keys have bright, easy-to-read
yellow graphics and is illuminated with white
LEDs.The keypad is supplied with a satin-chrome

AM-KPI

bezel and three interchangeable colored bezels
(white, ivory, & bronze) to customize the keypad
appearance for the installation.

AM-CRI Card Reader Interface

The Model AM-CRI expands the standard two
AM-3 Wiegand inputs by supporting one or two
additional 26-bit Wiegand input devices per
AM-CRI interfaces used. Each AM-CRI connects to

AM-CRI

the AM-3’s PBUS inputs.

Wiegand Accessories

Two Linear accessories are available to connect WIEGAND format devices to the
AM-3. Most other manufacturer’s 26, 30 & 31-bit WIEGAND output devices can
also be used with the AM-3.

WOR Wiegand Output Radio Receiver

For block-coded Linear wireless transmitters,
connect the Model WOR high-gain superheterodyne
UHF receiver. The receiver is housed in a weather­resistant enclosure and can be mounted indoors or
outdoors. Gaskets and a weather-tight wiring strain

relief seal the unit from the elements.

AM-PR Proximity Reader

The Model AM-PR is a radio-based reader that
works with either proximity tags (Model AM-PT)
or proximity cards (Model AM-PC), both of which
are slotted to attach to key rings. Upon reading a
user’s tag or card, it transmits the entry data via
a Wiegand output to the AM-3. An integral LED
confi rms to the user that access is granted.
