Wireless External Detector
This new dual PIR external short-range detector with sharp edge detection range of up to 5m,
virtually eliminates false alarms, thanks to its sharp, restricted short range,
which enables the detector to ignore disturbances such as trees, cars and by-passers outside the protected area.
The EXTPIR offers pet immunity of up to 10kg/22lb and is suitable for use outside the home in concealed areas,
or when installed with its dedicated protective hood (add-on),
can be used in fully external installations, offering utmost security outside the home.
Adding external pir triggering to an alarm system has a high potential of false triggering .
In the UK we readily accept visitors onto our property ( milkman, postman etc ) .
However they do work well in walled or gated properties
where visitors are controlled, quite normal in other countries .
Installers consider the consequences .
