16.8 Assigning Repeaters to the Radio Expander
The radio repeaters act as a ‘Range Expander’ and helps a system scale from smaller commercial sites to
large campuses with several buildings. Note: Repeaters will use an input from the radio expander.
¾ Press the ‘AZ’ and scroll to the input number you wish to assign a
repeater. To assign the REPEATER to that input, power the
repeater when the input number is displayed, and one dot will flash
to confirm. To remove a repeater from that input, press ‘CLEAR’

16.10 Problem Solving
One of the most frequent problems in not being able to assign the detectors to the Radio Expander is that
the jumper on the detector PCB has not been put in place on the ‘EU’ pins. This makes sure the transmitter
transmits at the correct 868MHz frequency which the zone expander uses.
Make sure that the ‘serial’ jumper on the radio expander is in the ‘MF’ position.
If there is “33” 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.
