lens is now lit for approx. 1 minute (warm-up phase).
TEST MODE:
After expiration of the warm-up phase, the LED extinguishes, and the sensor switches
to test mode automatically. Any movement within the surveillance area is now indicated by a lit
LED.
AUTO MODE:
If no movement is detected within the surveillance area for one minute, the sensor
switches to auto mode automatically, i.e. the sensor is now operable and reports any occurring
movement to the central station as an alarm signal. The LED on the sensor is no longer lit to save
battery power. If the central station is switched to "armed", an alarm will be triggered, and the
ZONE 1 LED on the central station lights up.
LOW BATTERY
: If the LED lights up during movements within the surveillance area even after
expiration of the test mode, then the battery’s life span is coming to an end. In this case, you
should immediately replace the old battery with a new one.
We recommend to regularly check the battery condition of the sensors, and to replace the batteries
once per year.
Important Remarks
False Alarm and Troubleshooting
A false alarm does not only cause an unpleasant shock, but has also the effect that your neighbors
will not react in case of a real alarm, because they assume "just another" false alarm. Therefore,
please pay attention to following very important points.
A) The alarm system is equipped with a radio sabotage protection. This means that an alarm will be
triggered, if the radio channel used by the system experiences interferences for longer than 5 secs.
This may occur, when e.g. a radio phone, radio headphones, or another transmitter is operated in
close vicinity of the central station. It is recommended to keep a distance of minimum 3 m to such
devices.
B) Before replacing batteries of the sensors, you have to interrupt the entire power supply to the
central station. Disconnect the emergency battery, if installed, and unplug the power supply from
the wall plug.
It is inadequate to switch the system to OFF using the hand transmitter
,
because opening the cover for battery replacement is regarded as sabotage and always triggers
an alarm, independent of the system’s switch status. After reconnecting the central station to the
mains supply, press the OFF key once on the hand transmitter to send a code to the central
station. This action is confirmed by two "beep" tones.
C) Before leaving your house, make sure that all secured windows and doors are properly closed. A
tilted window will normally not trigger any alarm, but it may be closed and reopened by wind which
in turn will then trigger an alarm.
D) While mounting PIR sensors, pay special attention to possible interferences within the surveillance
area (mounting point 20).
If you switched magnetic contact sensors to the 24-hr. mode, you must by all means unplug
the power supply from the wall plug and disconnect one of both connections to the emergency
battery before opening doors, or windows secured in this way. When you forget these steps,
an alarm will be triggered. Therefore, choose the 24-hr. mode only for windows and doors
which are normally always closed.
After resuming operation, press the OFF key on the hand transmitter. (Points 11+12)
