Glossary of Alarm Terms
intrusion protection Even the first break-in attempt is reported.
This is made possible by alarm components which do not only combine
state-of-the-art wireless technology with effective mechanical break-in
protection (mechatronic detectors), but at the same time monitor the
prying open of doors and windows with the help of a magnetic field sensor
Alarm panel The central switching station for the whole
alarm system, which processes all the information, forwards it and responds
Alarm system Burglar alarm system or danger warning
Alarm zone Each zone is monitored by a detector (for
wireless) or a detector group (for wire) and can be programmed separately.
Arming– when the burglar alarm system is triggered
(e.g. door open) it issues an alarm; "disarming" of an alarm
panel – does not issue an alarm when the burglar alarm system
is triggered; danger warning systems are programmed differently: if,
e.g. smoke is detected, an alarm should still be issued even when the
alarm panel is disabled.
Certification Test certificate from independent test institute
which certifies a high degree of quality and security for alarm systems
(Relevant in Germany: certification in accordance with accident prevention
regulations, insurance companies and VdS damage prevention).
Contact detector The detector recognises when a window,
door, window blind, garage door etc. is opened.
Danger detection system, danger warning system Alarm system which detects
break-ins and other hazards/emergencies and then issues an alarm.
Display Display on alarm panel for operating and programming
External siren Transducer for outside area, generally
configured as a combination transducer (siren + strobe light).
Glass breakage detector These detectors respond to
breaking glass. A differentiation is made between passive, active and
acoustic glass breakage detectors.
Interior protection The interior area of the building
is protected here, in particular those areas that a burglar would, in
all likelihood, have to pass through; generally motion detectors and
photoelectric barriers are used here.
Installation Mounting of panel and components including
Internal alarm The alarm is only sounded in the building,
the external sirens are not activated.
Internal siren Transducer for inside area, generally
a purely acoustic transducer (in addition external siren)
Motion detector Detector which recognises people on
account of moving heat (PIR), ultrasonics (US) or microwaves/"radar"
Perimeter protection All access to the property is
monitored here; this includes front doors, terrace doors, cellar doors,
skylights and all windows; generally used here are contact sensors,
glass breakage detectors and the wireless window lock – presence
in the building is possible at any time, even when the alarm is armed.
Perimeter surveillance Complete, large-area outdoor
protection of periphery or near field, e.g. through photoelectric barriers
and motion detectors on the site and/or surveillance cameras with intelligent
Programming Detailed settings for alarm panel to match
user requirements and wishes (e.g. specify zones/subareas).
Remote access/remote maintenance Maintenance/programming
of alarm panel using PC at home.
Silent alarm For this type of alarm the transducer
does not make any sound (in indoor and outdoor areas everything remains
quiet); a monitoring station is silently notified (burglars should not
be driven away, but rather caught, culprits should not be provoked into
Smoke detectors (Fire alarm) Optical smoke detectors
save lives because they respond to smoke particles in the air (generally
toxic gases): Thermal detectors/thermal differential detectors respond
to a maximum temperature (e.g. 65°) or signal a sudden rise in temperature.
Telephone dialler Device with which the alarm messages from
a panel are sent via telephone line. Telephone diallers can be integrated
into alarm systems already or be added as additional components.
Transducer Alarm device which issues the panel when
the corresponding command is given (siren, strobe light etc.).
Vibration detector These detectors react to vibrations
generated during a break-in.
Wire alarm system Alarm system with detectors that
are connected to the panel by wire (practical in new buildings or large
Zone Describes a closed electric circuit to which the
alarm or sabotage contacts are connected and which are connected with
the burglar alarm panel.
