Central Console Response
After acknowledging the alarm
transmission from the first
transponder, the central console begins
its alarm analysis while collecting the
alarm data from all other transponders,
which had receivers that detected the
alarm. The Subscriber Database is
checked to determine the appropriate
reaction to the alarm. If the
transmitter is assigned to a valid
subscriber and it is not designated as
a security or watchman device, the
central console commands the
transponders to turn on the appropriate
alert units. Depending on the settings
selected in the Security Preferences
Screen, this enables only the strobe
portion of the alert unit, or both the
strobe and siren. If the transmitter is
unassigned, or has been disabled by
selection of that option in the
Subscriber Database, no commands will
be issued to activate the alert units.
Note:
An option in the Security
Preferences Screen allows
unauthorized transmitters (not
programmed in the database) to be
treated like authorized
transmitters. For example, strobes
and/or sirens can be activated in
the case of an alarm transmission
(if they are also set to be
activated for authorized
transmitters).
The central console computes the
location of the transmitter by
comparing the signal strengths measured
by the receivers which detected the
transmission.
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.

During Alarm
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’s 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.
