2.4.5. Intruder Alarm
• Function: Intruder alarm system including Passive/Active detector contacts, Toggle switch
functions, Motion detectors, Manual and Door-lock Armouring, Code lock Armouring, Alarm
siren and Alarm signal
• Application: Wiring of intruder detector contacts to an alarm system
• Select with mouse (“Intruder alarm”) or short-cut key “I”
Description
The purpose of the Intruder Alarm is an alarm system consisting of various contacts integrated as Passive or
Active detectors.
Apart from the contacts represented by their own objects (Passive and Active dectector), it is also possible to
include toggle switch functions and motion detectors which have already been configured. This is done direct-
ly when setting the parameters for these objects.
A system which is enabled will then start an alarm when one or several alarm contacts have been activated.
The channel for the activated alarm channels (as alarm source indication) as well as the alarm output start to
flash after the set time delay. By subsequent activation of the Manual armouring, the Door-lock armouring or
Code lock armouring, the Mastergenerator switches the channel out of the system and switches the alarm out-
put off.
If an alarm is not acknowledged before elapse of the alarm signal delay, the system automatically becomes
alert again.
Note: For a minimum alarmsystem to operate correctly, according to Human behavior, the following objects
must be included:
a) means to start/stop the alarm, either “Manual armouring”, “Door-lock armouring” or “Code lock
armouring”
b) at least one alarm detector.
c) the "Silent Alarm Signal"
Either the "Door Lock armouring" or "Code Lock Armouring" may be combined with the "Manual armouring".
The Door/Code Lock has a priority over the Manual armouring. The Manual armouring allows alarm zones,
whereas the Door/Code Lock always include ALL alarm detectors.
The status of the alarm detectors can be shown in a simple way on a panel. All that is needed for this purpose
is that the output channels are coded to the addresses of the alarm contacts.
The object “Silent Alarm signal” is primarily intended for signalling an alarm-central, but equally important is,
that when this signal has been passed, the alarm-system resets the detected alarms, and the surveillance cycle
on the detectors is restarted.
The object Common Siren may be used as well.
The various Intruder alarm objects are selected under “Channel function”:
Passive detector:
This object makes it possible to control windows, doors, etc. with Passive
detector. If the contact is activated and a “1”-Signal consequently transmitted
on the Dupline bus, an alarm is started.
Active detector:
This object makes it possible to control windows, doors, etc. with Active
detector. When the contact is activated and a “0”-Signal consequently
transmitted on the Dupline bus, an alarm is started.
Manual
The Manual armouring operates like a toggleswitch, and is used to start and
armouring:
stop the Intruder alarm system.
The Manual armouring allows the alarm detectors to react upon their
respective disable addresses, whereby more alarm zones can be created.
