RMAS-120-81 and -91 UHF Radio Extensions

Introduction

The RMAS-120-81 and -91 adds a UHF

Radio Link to the RMAS-120 Remote

Monitor and Alarm System. The UHF Radio

Link provides an alternative transmission

channel for the RF Repeater Alarm data that

is otherwise carried by added modulation to

the repeated microwave carriers.

The -81 UHF Radio operates in the 902 ~

928 MHz band while the -91 UHF Radio

operates in the 2400 MHz band. Both use

frequency hopping spread spectrum coding.

These are license free bands under US-FCC

Part 15.247 rules and Canadian ISC

document RSS-210. The duplex radios are

GE MDS NETioB-900 and NETioB-2400

with Expansion Modules.

The RMAS-120-01 Alarm Transmitter unit’s

local alarm points are routed to the MDS

radio link equipment. Eight (8) alarm points

are transported in this RMAS-120-81

configuration. Other configurations can

transport 14 or 20 alarm points. Contact

PESi for availability.

Additionally, the battery temperature voltage

is transported on an analog voltage to

instrumentation current loop channel.

Alarms are sent from the RF Repeater site

to the RMAS-120-81, -91 UHF Telemetry

Receiver located at the associated

microwave radio terminal end.

The duplex radio link is configured with one

control channel from the Telemetry Receiver

to the RF Repeater site. This control

channel provides a closure at the repeater

site and can be used as required. Examples

are: GenSet start and equipment shutdown.

The radio link equipment is normally

configured at the PESi factory for the

particular field application. See the factory

test data sheet for more details.
