3. Detection Range:
The integrated HF sensor emits high-frequency electromagnetic waves
(5.8GHz) and receives their echo, any change in echo is perceived by
the sensor and will indicate the presence of a person(s) or animal(s).
A microprocessor triggers almost without any delay and will activate the
connected lights or applications. Detection is able to pass through glass,
doors and around partitions with 360 degree coverage. See Fig. D, E.
4. Safety Instructions:
1) Disconnect the power supply before any installation.
2) During the installation, the power cable must be voltage-free when
connected. Therefore we recommend you switch off the power and
check there is no voltage with a voltage tester – before you start.
3) Please note that the sensor must be protected by a 5A circuit breaker.
4) The mains cable needs to be 0.5~1.5mm².
