I - 1. IPDACT-UD Introduction
The IPDACT-UD is a device which, when connected to a security control
panel, carries out three basic tasks:
• To send over an IP network the alarm information sent by the panel
to which this is connected.
• To check the connectivity between the control panel and the alarms
reception center.
•
In cases where it is not possible to transmit over the IP network, the
IPDACT-UD will stop intercepting the alarms from the panel. At this
point the alarms will be sent over the telephone line.
The IPDACT-UD operates together with the Teldat VisorALARM device,
located in the alarm receiver center. This behaves as an alarm receiver which
receives the said alarms through an IP network (instead of the traditional
public switch telephone network) and sends them through a serial port to
automation software in order to be processed. Additionally, this receives
monitoring messages from multiple IPDACT-UD and generates the
corresponding alarm in cases where communication fails with one or more of
these.
I - 1.1. User Scenario
A traditional security scenario consists of a control panel (CP), located in the
client environment and an alarm receiver center (ARC) located in the security
company’s control center. The CP contains a group of sensors which trigger
a series of alarms or events which, when produced, are sent to the ARC to be
processed.
Communication between the above is traditionally carried out over the
telephone line so that both ends can initiate a call to the remote end: the CP in
order to notify events and the ARC for bi-directional tasks (activation,
teleloading and general control).
The communication protocol varies depending on the manufacturers who
usually tend to use their own solutions. The IPDACT-UD supports Contact-ID
protocol.
The CP is placed as the first connection element to the PSTN so that it can
prioritize the customer’s telephone line.
