Audio alarm as an intrusion deterrent
Audio system for broadcasting announcements for deterrence purposes as a support to perimeter alarm systems protecting critical
installations in large areas
Our partner EON SYSTEM, which operates in South Korea, submitted to us the request of one of its customers, who manages several
power plants including the one in Pyeongtaek that is the subject of this first project, for the development of a solution that
would allow control room staff to interact in real time with those who were trying to force the perimeter fence installed to
protect the plant.
Scheme of the system installed in Pyeongtaek (SOUTH Korea)
It should be noted that EON SYSTEM had already planned to install along the site fence a perimeter alarm system divided into
zones, each of which would be monitored by IP cameras whose images would be displayed at the control room so that staff could
monitor events in the proximity of the alarmed zone.
Ultimately, the request consisted in integrating the usual perimeter protection system with an audio system that, when the alarm
was triggered in a given area, would automatically broadcast an audio message previously stored for deterrence purposes and also
allow the operators of the control room to interact in a more targeted manner with the intruders, visualized by means of the CCTV
system, broadcasting more specific warnings by means of a microphone console.

Pyeongtaek Power Plant (South Korea)
Despite the size of the area to be covered and the considerable distances involved, the problem was easily solved by using the
SoundLAN family of IP amplified audio gateways.
The gateways were installed one for each zone into which the alarm system is splited and were connected to the control room
using the same data network infrastructure already in place for the connection of the IP cameras.
The message to be broadcast for deterrence purposes has been memorized on each gateway and is automatically reproduced on the
basis of a command generated by the relevant section of the perimeter alarm system; the control room operator can interrupt the
broadcasting of the automatic message at any time in order to switch to the broadcasting of live announcements via the IP
microphone console installed in the control room.
Dangjin Power Plant (South Korea) |
IP amplified audio gateways were also used at the Dangjin thermal power plant, also in South Korea, to solve another problem
related to the fishing ban in force for safety reasons in the waters in front of the plant. |
All in all, the gateways in the SoundLAN family are a practical and efficient solution for integrating a
public address system
with other types of security systems.
