Introduction
IP
Internet Protocol, a network protocol widely used in
computer networks.
Jamming
Interference that makes normal reception of wireless
emissions of electromagnetic waves difficult or impossible.
The source of interference sends out energy in the form of
electromagnetic waves, just like the instruments affected by
the interference, which overlap the original waves either
partially or completely.
Combination signalling device
Combined sounder, e.g. siren (acoustic signal) + strobe
(visual signal).
Communication options
Used to transmit alarm notifications using additional
routes, e.g. wirelessly (GSM module) for voice/text
messages or digital protocols.
Devices
See system components
Receiving centre
See ARC
Line
Another term for zone, mainly used in wired areas.
Local alarm
(Alarm type)
If this alarm is triggered the sounders indoors and
outdoors sound (outdoors the acoustic alarm (siren) must
stop after 3 minutes if in Germany, but the visual alarm

The MAC address (Media Access Control, Ethernet ID)
is the hardware address of every single network adaptor,
used to uniquely identify the device in the network.

ARC
Receiving centre; in an alarm receiving centre, messages
collected in connected subscriber zones, e.g. from
danger alarm systems or building technical equipment,
are transmitted, received, documented and processed,
and intervention is provided, via the power supply of the
network operator (leased lines), the public telephone
network, Datex-P/X.25/X.31, IP, GSM, ISDN, or in
Switzerland, via TUS (Alarmnet). Receiving centre from
private security service providers also control call for
intervention services (police/fire brigade).
Magnetic contact
A detector that identifies when a window, door, shutter,
garage door, etc. is opened.
Perimeter surveillance
Continuous monitoring of large areas of open land
around the periphery or the areas used for approaching
the property, e.g. using light barriers and motion
detectors on the premises and/or surveillance cameras
with intelligent motion detection.
Port
Part of a network address.
Configuration
Detailed settings for the alarm panel according to the user's
requirements (e.g. zones/sub-areas can be defined).
PSTN
Public Switched Telephone Network, analogue, a/b
