A total of 7 detectors can be programmed using the End of Line mode on a radio expander, and 29 can be
programmed using the ID mode.
The ‘OK’ and ‘FAULT’ LEDs relate to the RS485 connection to the PCX system.
NOTE: The last input on the expander should be programmed as ‘Fault’ with the name ‘RF Low
Battery’ to indicate a detector low battery problem. If an RF Low Battery is reported then the radio
expander will show on the display the number of the detector with the low battery: e.g.
Lb…21
.
Supervision failure will be reported as ‘tamper’ on the relevant input.
