A partial map of the protected area is displayed on the Central Console, centered on the
computed location, and, a yellow circle is drawn to assist the operator in guiding the response
personnel to the probable source of the transmission. Other data drawn from the Subscriber
Database is added to the Central Console display to assist in the response to the alarm. In
addition, the Central Console enunciator is activated to alert the operator to the event.

The Central Console also writes the time, location, and identity information to the hardcopy
printer and writes a complete record of all activities to the hard disks on both the primary and
backup computers.
Operator response
The operator reacts to the alarm by acknowledging the event with a keystroke or click of the
mouse, which silences the alert sound from the Central Console. This silences only the Central
Console enunciator, not the outdoor sirens or interior horns. The operator then directs
response personnel to the scene and awaits their indication that the problem was resolved.
When the response personnel advise the operator that the problem is under control, the
operator enters his password into a box on the Central Console. This step causes the Central
Console to send commands to the transponders to silence the sirens and horns and extinguish
the strobes and LED's. A reset of the system is accomplished with another key stroke or a
mouse click on the Reset button on the screen.
Multiple alarms
Receivers can handle multiple separate alarm or test events at the same time. If the receiver's
event buffer is full but contains test events, it discards the test records in favor of an incoming
alarm. Similarly, the transponder event buffer can hold multiple events and it also replaces
test events with alarm events when its buffer is full.
To assure that simultaneous alarms are detected, the multiple identical packets sent by the
transmitters are randomly spaced over approximately one second. Only one of the packets
must be detected to produce an alarm. Thus a collision between the transmissions of two or
more transmitters is virtually eliminated. In addition, unless the transmitters are in the same
location, they detect different groups of receivers. The Central Console is capable of
