1.1 System Components
1.1.1 System Overview
The Security Escort System consists of
five basic components: transmitters,
receivers, alert units, transponders,
and the central console.
The transmitter is a miniature, radio
transmitter, used to transmit either a
distress or a test signal. The
receivers are located throughout a
protected area and detect the radio
transmissions from transmitters. Alert
units are siren/strobe units activated
in the event of an alarm. Transponders
are devices that control groups of
receivers and alert units, connected to
them by wire. Each transponder relays
alarm and test signals from its
receivers to the central console. In
addition, the transponder tests for
device and wiring faults, and transmits
problem conditions to the central
console. The central console consists
of a computer (the master computer), an
optional backup computer (the slave
computer). Up to eight optional
workstation computers can be used to
receive alarm and trouble signals from
the transponders, analyze the signals,
activate strobes and sirens on the
alert units, and produce a display for
the security dispatcher. Each of these
system elements is described more fully
below.
1.1.2 Transmitter
There are several types of transmitters
for personal use; those normally
assigned to system subscribers, one for
security personnel, and one for
maintenance personnel. Each transmitter
type serves a different purpose. All
versions of transmitters for personal
use produce alarm and test
transmissions.
Subscriber Transmitter
Each transmitter contains a unique
code, which is associated with the
subscriber at the time the transmitter
is assigned. In the event of an
emergency, press and hold the alarm
button(s) for 1 sec. to produce an
alarm (see your transmitter user
manual). Optionally, within
approximately 2 sec., the sounders in a

Each transmitter contains a unique
code, which is associated with the
subscriber at the time the transmitter
is assigned. In the event of an
emergency, press and hold the alarm
button(s) for 1 sec. to produce an
alarm (see your transmitter user
manual). Optionally, within
approximately 2 sec., the sounders in a
nearby receiver activate, as well as
the strobes and sirens on nearby alert
units.
The transmitters have a second feature,
the test mode. When the user is
indoors, in sight of an interior
receiver or outdoors, in sight of an
alert unit, pressing the test sequence
performs a test (see your transmitter
User’s Manual). If the test is
successful, a small green light flashes
on the interior receiver, or the strobe
on an alert unit flashes briefly. There
is no response at all if the test
fails. If the test fails, the user
should try again. If there is still no
response, the user should contact the
security office as soon as possible.
Every successful test is recorded in
the Subscriber Database in the central
console software and optionally printed
on the hardcopy printer. The Subscriber
Database contains all of the
information relating to each
subscriber, including the date and time
of the most recent test transmission.
It is possible to search the Subscriber
Database for individuals who have not
performed tests for a specified period
of time.
Security Transmitter
The Security Transmitter are unique in
the way that both tests and alarms are
processed. Outwardly, Security
Transmitters perform in the same manner
as normal transmitters during testing.
That is, strobes flash on alert units
and green lights flash on receivers to
confirm a successful test. However,
when a Security Transmitter is tested
within close proximity of a receiver,
the central console records not only
the user identity, and the date and
time (as with a normal user test) but
also the location of the officer at the
time of the test. These tests are
designated by the term security test on
the printout at the central console and
provide a convenient means of recording
security patrols. (To protect user
privacy, location information is not
printed out for regular subscribers
during tests.)
The Security Transmitters also differ
in the way that alarms are managed.
Unlike regular transmitters, no sound
is emitted from the transmitter itself,
no horns are activated on receivers,
and no strobes or sirens are activated.
