Problem Solving
One of the most frequent problems is not being able to assign the detectors to the Radio Expander. This is often
because the jumper on the detector PCB has not positioned on the ‘EU’ pins. This makes sure the transmitter
transmits at the correct 868MHz frequency which the input expander uses.
Make sure that the ‘serial’ jumper on the radio expander is in the ‘MF’ position.
If “33” is displayed on the screen and can’t be cleared, it is because the expander has been selected for “A0” not
“E0”. You will need to power down the expander and address it again.
