LED Indications
LED Indication
Zones are enabled in Standard Mode
No Communication
Zones are enabled in Inertia Mode
= ON,
= SLOW FLASH,
= FAST FLASH
NOTE 1: It is not possible to connect two 4-zone RIXs that have the SAME 4 zones enabled (one RIX
MUST be zones 17 - 20, the other MUST be zones 21 - 24).
When connected, initiate scan for devices on the bus by entering .
When changing between on-board and remote expanders on an already installed system, you should remove
all the expanders, scan for devices, and then add the expander and perform another scan. This way the
Matrix panel will correctly detect the expander.
NOTE 2: During local up / down loading periods the Matrix panel will stop communications with
the remote zone expander, and LEDs 1 and 2 will flash.
