Description
The Transponder is a device controller for up to 64 devices -- any combination of Receivers
and Alert Units. Its primary function is to monitor the Receivers and Alert Units and report
conditions and events to the Central Console via either wire or ProxLink radios. It also
provides power output to certain devices.
Installation
The Transponder can be mounted in one of two different sized enclosures. It is always
mounted indoors. The devices are connected to the Transponder by means of eight four-wire
Multiplex Busses, two wires for power and two wires for data. Each bus is capable of
supporting up to eight devices. A Security Escort System supports up to 255 Transponders.
Configuration
Each Receiver and Alert Unit is identified to its Transponder by a Multiplex Address which is
set during system installation using a multi-position switch on the Receiver or Alert Unit circuit
board. Transponders communicate on the data bus with individual Multiplex devices by
issuing commands, which contain the Receiver or Alert Unit's Multiplex Address.
Setup and Testing
Each Transponder and the devices connected to it are set up and can be tested remotely from
the Central Console. Also, each Transponder reports any problems, such as low battery,
immediately upon detecting them.
Function During an Alarm
When a Receiver or Alert Unit detects an alarm, it goes into an "Off Normal" state. To quickly
locate any devices which might be in the "Off Normal" state, the Transponder issues global
commands (which are interpreted simultaneously by all of its devices) approximately 10 times
per second. These global commands are followed by commands to specific devices to
determine the nature of the "Off Normal" condition and, in the case of an alarm (or test), to
obtain the Transmitter Identification Number, Transmitter battery condition, and received
signal strength. This information is then sent to the Central Console, by either wire or through
ProxLink radios, where it is used to graphically display the identity of the subscriber
transmitting the alarm and to determine the subscriber's location.
