Introduction

IP
Internet Protocol, a network protocol widely used in com-
puter networks.
IP mobile
Synonym for 4G (LTE) and 2G (GPRS) IP-based trans-
mission
Jamming
Interference that makes normal reception of wireless
emissions of electromagnetic waves difficult or impossi-
ble. 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 sounder
Combined sounder, e.g. siren (acoustic signal) + strobe
(visual signal).
Communication options
Used to transmit alarm notifications using additional
paths, e.g. wirelessly (wireless mobile module) for
voice/text messages or digital protocols.

Line
Another term for zone, mainly used in wired areas.
Local alarm
(Alarm type)
If this alarm is triggered the sounders indoors and out-
doors sound (outdoors the acoustic alarm (siren) must
stop after 3 minutes if in Germany, but the visual alarm
(strobe) can remain on).
LTE
Long Term Evolution ( LTE for short, also 3.9G ) is the
name given to the third generation wireless mobile
standard. An extension is called
LTE-Advanced, or
4G, it is backwards compatible with LTE in the Next
Generation Mobile Networks (NGMN) project. For mar-
keting reasons, LTE is already advertised as 4G and
LTE-Advanced as 4G+, which, technically speaking, is
not correct.
With up to 300 megabits per second, depending on the
reception status, significantly higher download speeds
are possible than with older standards.
For this, LTE wireless mobile providers exclusively use
the UHF frequency band (also known as the decimetre
waveband) for their frequency range. Within this, sev-
eral frequencies are used, varying regionally in the
central to upper UFH range from approx. 700 to 2600
Megahertz.
The basic schema of the Universal Mobile Telecom-
munications Systems (UMTS, 3G) is retained for LTE
(3.9G). This allows for quick, cost-efficient retrofitting
of the UMTS technology infrastructures, e.g. to LTE-
Advanced (4G).
MAC
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.
Medical emergency
Personal medical emergency, for which help can be ar-
ranged using an alarm.
Mobile
Synonym for the following transmissions in the wireless
mobile network:

Voice calls with a telephone number, e.g. +49
173 1234567

ARC reporting classic DTMF or FSK based, such
as FF, CID, SIA, Scancom, Scanfast, Tunstall

SMS transmission
NC
Normally Closed; contact or switch that opens when actu-
ated
NO
Normally Open; contact or switch that closes when actu-
ated
Alarm and relay command centre
See ARC
ARC
Receiving centre; in an alarm receiving centre, messages
collected in connected subscriber zones, e.g. from dan-
ger alarm systems or building technical equipment, are
transmitted, received, documented and processed, and
intervention is provided, via the power supply of the net-
work operator (leased lines), the public telephone net-
work, Datex-P/X.25/X.31, IP, GSM, ISDN, or in Switzer-
land, via TUS (Alarmnet). Receiving centre from private
