Perimeter protection
All points of access to the premises are monitored, in-
cluding house doors, terrace doors, cellar doors, sky-
lights and all windows. Usually magnetic contacts, glass
breakage detectors and wireless window/door locks are
used. The building's occupants can still move around
freely within the building when the alarm system is armed
internally.
Outdoor siren
Sounder for outdoor use, usually designed as a combina-
tion sounder (siren + strobe).
End of line (EOL)
End point of the line system, end point of access to tele-
phone network.
The line end point or "building distribution for telephone
lines" is the end of the distribution cable for the consumer
connection line within the telephone network.

User
Different users of the alarm system (e.g. owners, tenants)
can be assigned separate rights and user codes.
User guidance
Electronically guided help for operating the alarm panel.
Motion detectors
Detector used to identify people by thermal movement
(PIR), ultrasound (US) or microwave/radar (MW).
Bidirectional 2-way wireless (2WAY)
Unidirectional: components (e.g. remote control) and
control modules only transmit commands to the alarm
panel. Bidirectional: components can both receive the
feedback from the alarm panel and evaluate it (e.g. via
LED displays).
