Fail-Safe Operation
The XPander I/O Unit can be used in fail-safe* operation where relay outputs are reset to
the non-active state on the event of internal battery pack failure or loss of radio communi-
cation.
*
Note - Requires compatible control panel software
The eighth segment is used to select normal (OFF) or fail-safe (ON) relay operation.
