INTRODUCTION

The AM-RRR remote radio receiver is designed for use with Linear’s Model
AM/II access control system. The AM-RRR functions as a remote device that
extends the radio range or supplies localized radio reception for the AM/II.

Three antenna types can be used with this receiver. The cabinet mounted
type “F” connector is for connection to the antenna. The local whip antenna
(supplied) screws directly on to the receiver’s connector. The directional
(EXA-2000) and omni-directional (EXA-1000) remote antennas wire to the
receiver’s antenna connector with type RG-59 cable.

An on-board RADIO RANGE knob allows adjustment of the receiver’s gain.
It can be set to limit the maximum radio range that the receiver can achieve.
Two indicators display the receivers performance and operation. The two color
red/green STATUS indicator lights red when the receiver is getting DC power
and turns green when access is granted to a transmitter. The RADIO indicator
lights when the receiver detects a radio signal. It can be used for trouble
shooting and verifying system performance. Receiver test points are provided
for listening to the incoming signals.

The AM-RRR remote radio receiver connects to the AM/II control unit through
a six-wire cable. A rotary switch in the AM-RRR selects the device address
for the receiver. Each remote device connected to the AM/II must be set to a
different device address. Power is supplied to the receiver from the AM/II.

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 from the elements.

IMPORTANT !!!

Linear radio controls provide a reliable communications link and fill an important need
in portable wireless signalling. However, there are some limitations which must be
observed.

✶

For U.S. installations only: The r adios are required to comply with FCC Rules and Regulations as Pa rt 15
devices. As such, they have limited transmitter power and therefore limited range.

✶

A receiver cannot respond to more than one transmitted signal at a time and may be blocked by radio signals
that occur on or near their operating frequencies, regardless of code settings.

✶

Changes or modifications to the device may void FCC compliance.

✶

Infrequently used radio links should be tested regularly to protect against undetected interference or fault.

✶

A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale distributor or
dealer, and these facts should be communicated to the ultimate users.
