An
All Partitions
option is available to assign or de-assign the expander to or from all
partitions.
Wired Zone Type
You can change the zone wiring method for each wired expander individually. The
available options can depend on the expander type.
Please refer to page 14 for details of the wiring types.
Loudspeaker Volume
You can use this option to change the volume of notification tones from loudspeakers
attached to expanders. Press
to lower the volume or
to raise the volume. The display
shows the current volume setting by a row of stars (for example “****”). You can also press
one of the number
keys to specify the volume in a range 0 to 9 (for example, pressing “8”
gives you eight stars on the display).
This volume control does NOT change the volume of alarm tones, the control unit will still
give these at full volume.
Note:
When you first add an expander to the bus, the control unit defaults the loudspeaker
volume to zero.
Battery 2
This option is available when editing an EXP-PSU. You can use the option to enable or
disable alert reporting on a second backup battery that may be fitted within the EXP-PSU.
If you select Enabled, the control unit will start an alert if battery 2 is missing or has low
voltage. If you select Disabled, the control unit will ignore the presence or absence of
battery 2.
Delete Expander
Always use

when you wish to remove a wired expander from the bus.
Using this option defaults the bus device number stored within the device (making the
device safe to add to other systems) and deletes zones and outputs associated with the
device. Exit the Installer menu to save the change.
Note:
Remove all power from the system (battery and mains) before disconnecting any
device from the bus.
Enable Expander
Set this option to No if you suspect that the device is faulty, and wish to remove it from
service temporarily.
The effects of disabling any expander or keypad are as follows:
The control unit ignores all signals from the device, but retains the zone numbers
and other configuration allocated to the device.
The control unit activates any output of type General Fault.
A disabled keypad shows flashing red navigation LEDs (and will not accept any
user input).
Keypads (those that are enabled) show 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 device. If a user tries to set the system, the
