IDS X-Series Training v2.7 | Hardware
7. Onboard Expander Connection
The number of zones on the X64 and X16 alarm panels can be expanded via zone expanders. Zones 9 to
16 are added by plugging the onboard expander (or plug-in expander) onto the PCB via this connector.
Not available on the X8s.
8 pin connect Standoff mounting hole
8. Keypad Bus
All devices connected to the bus should be connected in a daisy chain formation (one after each other) for
the best results, though the X-Series Panel does not need to be in the beginning or end of the daisy chain.
Note: All X-Series keypad bus devices must be powered from the X-Series panel unless an IDS RS485 Bus
Isolator is used, as described in point 8.6.
