8 Anti Vandal Function
The PIR is equipped with a sophisticated protection against vandalism . These detectors can sense certain
changes of their alignment from the original position as set during the installation. A change of the detector’s
alignment generates a permanent alarm
until the detector’s alignment is back in its original position or until
the position has purposely been reset .
When using the alarm management with RS 485 communication a vandal alarm will be identified separately.
After the turn-on time of typ. 60 seconds from power on, the detector determines and stores its alignment position
(only with detector cover closed).
After opening and closing the cover with the unit powered on, the detector determines its alignment position and
stores the position value after 5 minutes again without having the detector in permanent alarm state.
The anti vandal sensor can be reset remotely with the setup program (takes app. 10 seconds) or with a power off-
on (60 seconds).
Hardware Mode:
When operating the detector in the HW mode, the anti vandal function is activated by setting DIP – Switch 6 to „on“.
Software Mode:
Operating the detector in the SW mode, the anti vandal function is activated by means of setting of the
corresponding parameter in the settings of the setup program to „on“.
9 LED
The electronic board is fitted with a dual LED having a red and green colour side. This can be monitored during
installation while the cover is open.
ƒ
The red LED indicates whether the detector is in alarm state or not
ƒ
The green LED flashing at 2 Hz frequency indicates the detector ready state.
During the turn-on time the red LED is on.
10 Alarm Management
The PIR features an alarm management function over RS 485 communication. All the detectors connected to the
same data bus provide all the information relevant to an alarm in a defined protocol frame. For further information
please contact the manufacturer.
11 Alarm Time
Alarm time per event is determined by the duration of the detected event and depends on the shape and amplitude
of the alarm signal. Individual alarm pulses have a minimum time of app. 2.5 s.
12 Internal Temperature Compensation
The PIR is detecting radiation differences of a target against its background. In the course of the day and year the
contrast of a person will vary considerably and affect the signal strength. To compensate for this contrast variation,
the PIR has internal temperature compensation with maximum sensitivity at app. 30°C (where the contrast of a
human target is weakest) and gradual reduction at higher and lower temperatures.
•
When installing a unit the internal temperature may take up to 30 minutes or more to stabilise to the actual
external temperature. Sufficient time should be given to the PIR to reach the correct internal temperature and
sensitivity before performing walk tests.
During the initial period of operation it is strongly recommended that walk tests are repeated and signals monitored
under various weather conditions such as high and low temperatures, wind fog, snow, rain etc. to obtain
comparative data and information on the effects of environmental conditions on detection and nuisance alarm
probabilities for this particular site. Fine-tuning of the detector based on this data by changing the sensitivity
settings may optimise the performance.
13 Internal Heater (H version only)
A regulated heater connected to the electronic board and powered by the supply voltage of the PIR-100H prevents
the optical surfaces from fogging or frosting and maintains the internal temperature at optimal levels.
