Installer Menu Options
Enabled
The control unit will start an alert if EXP-PSU battery 2 is missing or has low voltage.
Disabled
The control unit will ignore the presence or absence of EXP-PSU battery 2.
Deleting Expanders
When you wish to remove an expander from the bus always use the Installer Menu option
Detectors/Devices – Wired Expander – Delete Expander or Detectors/Devices – Radio
Expander – Delete Expander.
Using these options defaults the bus device number stored within the device itself (making
the device safe to add to other i-onEX alarm systems), frees all the zone numbers
allocated to the device, and also removes the device from any partitions it was allocated
to.
Note: Eaton's Security Business recommends that you remove all power from the system
(battery and mains) before disconnecting any device from the bus.
Disabling/Enabling Expanders
If you suspect that an expander is faulty, and wish to remove it from service temporarily,
then use the Installer Menu option Detectors/Devices – Wired Expanders – Enable
Device. (There is a similar option for radio expanders and keypads.) Select the device you
wish to disable and use the  or  keys to set the enable status to "No".
To return the expander to service use the same Installer Menu option and set the enable
status to "Yes".
While the expander is disabled the control unit ignores all signals from the device, but
retains the zone numbers and other programming allocated to the device. The control unit
also activates any output with type "General Fault". The keypad shows an alert (navigation
key LEDs glow red). When a user reads the alert the display shows "Tick to continue
Disabled" followed by the device number of the disabled expander.
If a user tries to set the system the keypad display shows the same alert message again,
but will continue to set the system if the user presses . The system omits all those zones
belonging to the disabled expander.
Replacing Expanders
If you wish to replace an expander with a new expander, but leave that expander's
programming intact on the control unit, then use the Installer Menu option
Detectors/Devices – Wired Expander – Replace Expander. Radio Expanders have a
similar menu option.)
When you use the Replace Expander option the control unit disables the selected
expander and retains all the expander's zones and other programming. You can then
power down the system, disconnect the expander from the bus, and reconnect a new
expander (of the same type) to the bus.
When you power up the control unit again, the keypads will show an alert that the
expander has been disabled. Go into the Installer Menu and select Detectors/Devices –
Wired Expander – Replace Expander again. The keypad display shows an "Add" option
for the replaced expander. Select the "Add" option and then hold down the address
request button on the new expander (remember to remove the lid in order to activate the
tamper). The control unit will assign the bus device address of the expander you removed
to the new expander, along with all the zones and other programming from the old
expander. The new expander will not need any further programming.
