enabled when the expander is in tamper. When in commission mode the RF signal
is attenuated by -6 dB, and will reject weak signals. This means that when devices
are placed into their final locations and communications are established, you can
be sure that the signal path is secure, and robust.
After entering Commission Mode the expander will also instruct the devices to poll
in every 4 minutes, rather than the standard 15 minute poll time. The instruction
will be sent with the next available poll to the device.
Device Commission Mode
At any time, when a tamper is generated on a device it will enter commission
mode, the devices will do this regardless of the state of the receiver. Closing the
tamper circuit will activate the LED for a short period of time whilst communication
with the receiver is established.
The LED will flash, indicating the device is trying to communicate with the receiver,
once communication is successful the LED will come on solid and then go out.
If the LED does not flash but simply comes on solid when the tamper is closed,
then a valid & secure communication has taken place. If the LED flashes and then
goes out, without going solid communication has failed.
This method of commissioning devices ensures that valid and secure
communication is taking place and that signals are reaching the receiver. It is
recommended that Device Commission Mode is used in conjunction with Expander
Commission Mode. See Above.
