Microtel Series 250 - Manual (Page 5)

I. INTRODUCTION
A. GENERAL
INFORMATION
The purpose of this manual is to completely explain the function, installation, and
operation of the MCS Model 250/Real Voice Communication system. This automatic
dialing, synthesized speech, telephone based monitoring system represents a new
generation of computer controlled telemetry devices, with features and capabilities not
found in any other telephone oriented monitoring system. The device is designed
specifically for industrial based equipment monitoring needs, by the engineering staff
which invented the concept of synthesized speech dialers. The Real Voice System
allows the user to actually train the system to place alarm calls. The system can then
inform the called individual of the precise location and nature of the alarm condition
using a digitized sample of the user’s voice.
The System is configured to accept four channels of normally open or normally closed
fault state switches (contacts), such as float switches, pressure switches, temperature
switches and similar devices that contain an unpowered contact that changes state
whenever a preset condition changes. Fault recognition can be set to respond after 1
second or delayed for up to 99 seconds, programmable on a channel-by-channel basis.
Internally, the system monitors its own power supply and will respond to any power
outage which persist longer than the user programmable time period.
When the dialer system recognizes an alarm condition, due to the opening or closing of
an external contact, it begins to place a series of telephone calls. The dialer system is
able to dial up to eight different telephone numbers, in an attempt to make contact with
a qualified person to whom it can deliver a combination of digitally stored voice
messages, describing the location and the type of alarm condition. These messages
are originally programmed by the user at the time of system installation.
The system will continue to call the list of up to 8 telephone numbers, insisting that its
message be heard.
The dialer system can be called at any time to check or verify the monitored conditions.
The following instructions generally describe the installation, operation and maintenance
of the equipment. Microtel reserves the right to make engineering refinements that may
not be described herein.
