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
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.
