Getting Acquainted
To the New
Operator
Working in a Central Station can be a rather imposing responsibility. To a
newcomer, the busy atmosphere, along with the electronic equipment,
computer screens, and telephone consoles may seem very imposing. Beneath
it all lies the primary purpose of the Central Station: to help protect the life
and property of its commercial and residential customers, people who have
security systems installed in their businesses or homes. Central Stations
also provide other functions for their subscribers, which will become
apparent as you get better acquainted with your responsibilities. Either
way, you can be proud that you are associated with an organization
dedicated to the safety and security of its customers. In your role as an
operator or dispatcher, you will no doubt make an important contribution to
that cause.
This manual has been written to help to acquaint you with one of the major
elements in your Central Station's operation—the
FBI CP-220A Central
Station Digital Receiver.
What Is a
Central Station
Digital
Receiver?
A
Central Station Digital Receiver
is a key piece of equipment found in
virtually all Central Stations. It is designed to receive information about the
events detected by the security system in the premises of the Central
Station's customers. Such events may have a bearing on the customer's
well-being, the security of the premises, and even the operation of the alarm
system itself.
The transmission of information to the Central Station is normally initiated
as a telephone call by the security system at the customer's premises and
carried over the regular telephone network to the Digital Receiver at the
Central Station. Once the Receiver answers the call, electronically encoded
information related to the customer's account is communicated. Once such
messages have been checked for accuracy and are determined to be
legitimate, the Receiver at Central Station sends a signal back to the
customer's alarm system informing it that its message has been received
and instructing it to "hang up" the line.
Figure 1-1 on the following page summarizes this process and illustrates
how it takes place. The circled numbers in the figure refer to the sequence of
events listed below it.
