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

Important Mounting Requirements

The AM-3 Access Control System can be installed for public or private use.
The mounting requirements for remote keypads will vary depending on the
installation. Review the following information before starting the installation.

Mounting Environment

Consider the environmental factors at the desired mounting location.
Although the exterior keypads are designed for direct outdoor
installations, it is necessary to protect the AM-3 from extreme exposure
to sun, driving rain, or snow. Mounting the unit in a kiosk can provide
extra environmental protection. Use a Model CAB-3 (P/N ACP00913)
cabinet for mounting the AM-3 outdoors.

Follow Building Codes

Check all local building codes and ordinances prior to installing the
system. Proper installation of the AM-3 conforming to the local building
codes for access control equipment is a regulatory requirement. The
AM-3 and remote keypad installation is an extremely important and
integral part of the overall access control system.

Mounting Location

If the AM-3 is used to control a door or pedestrian gate, locate the remote
keypad as near as practical to the entry point. If the unit is mounted on
or in a wall adjacent to the entry point, be sure the wall is sturdy. The
repeated shock and vibration from a slamming access door or spring­loaded pedestrian gate must be isolated from the keypad. NEVER

MOUNT THE KEYPAD DIRECTLY TO A MOVING DOOR OR GATE!

Optional Network Connection

Linear’s AM-3, AE-1000, & AE-2000 Access Control Systems can
be connected together in a network. A network will allow sharing
programming and user information between the systems. Program each
unit to a different network Node Address.

Network wiring conforms to 3-wire RS-485 electrical specifi cations. Units
connected in the network can be wired using one unit as a “hub” or by
wiring from one unit to the next in “daisy-chain” fashion. See the fi gures
for wiring options.

• Use Belden 9925 or Carol C0600 shielded cable or equivalent.
Maximum wire run distance is 4000 feet.

✦ NOTE: Be sure to connect the cable’s shield to one of the GND

terminals.

Home-run Network

1. Mount and install the units for the network.

2. Choose one unit to be the Network Master. Usually this would be a
centrally located or “main” unit.

3. Route 3-conductor shielded cable from the Master unit to one of
the other units. Repeat this step to connect the Master unit to each
of the other units.

4. Connect the 3-conductor cable to each unit’s NETWORK
terminals.

Daisy-chain Network

1. Mount and install the units for the network.

2. Route 3-conductor shielded cable from one unit to the next unit
until there is cabling run to all of the units.

3. Connect the 3-conductor cable to each unit’s NETWORK
terminals.
