Description
The object “Motion detector” makes it possible to include Dupline Passive Infrared Detector (PIR), eg
G8910 1127 and conventional motion detectors, which are connected to the Dupline bus via binary inputs.
The PIR detector can have an off time defined and be integrated in the intruder alarm system. Thereby it
becomes possible to avoid false alarms by setting the number of impulses which must be detected within a 10
s time window before the alarm starts.
Note:
If you want a PIR detector to generate the off time indepedently, the object “Push-button function”
should be used.
The off time of G8910 1127 can be operated through DIP-switches.
Parameters
Configuration window of Motion detector:
• Function: Includes motion detectors or similar input modules in the Dupline system.
• Application: Control of lamps and integration in the intruder alarm system
• Off time adjustable from 00 h 00 min 00 s to 99 h 59 min 59 s
• Variable number of movement impulses helps to avoid false alarms in the intruder alarm
• Select with mouse (“Motion detector”)
Parameter
Description
Off time:
The time for which the channel remains activated (00.00.00 to 99.59.59) after a
motion impulse has occured. Each additional impulse will start the off time
again.
When entering an off time of 00:00:00, the Mastergenerator generates a short
output signal indpendently of the duration of the input signal.
Number of pulses
The value entered here (1..25) determines how many impulses the motion
detector may generate within 10 s, before the alarm starts.
When an impulse is detected, the Mastergenerator checks whether the number
of impulses during the past 10 s has exceeded the set number. If this is the
case, an alarm is generated in the connected intruder alarm system.
This setting thus reduces the risk of false alarms.
Note:
Since the signal output takes place subsequently, an additional impulse is
always needed. This means that when the number of impulses is set to 3, the
alarm will go off at the fourth signal. The set off time has no influence on the
alarm.
Use in Intruder alarm
Click in the check box in order to include the channel in the intruder alarm
system.
When the Intruder alarm is armed, it will accept the information from the Motion
detector as well, and cause the alarm to acticvate.
Disable Adress
The Disable address, when set and active. disables the signal sent to the
intruderalarm. The disable address then makes it possible, to use the motion
detectors in different alarmzones.
Invert PIR input signal
If the motion detector has a “normally closed” output, then this check should be
marked, to make the function operate correctly.
