Installer Menu Options
Notes:
1. If you are working on a system with only one keypad (for example when
programming a new control unit before installation) then do not delete the keypad
you are using by holding down D and
in order to make the control unit recognise the keypad. If you try to use the Installer
Menu to delete the keypad you are using then the control unit will display the
message "Cannot delete keypad in use".
2. DO NOT hold down D and
still connected to the bus. Always delete keypads from a system first by using the
Installer Menu. If you have inadvertently erased a keypad's address by holding down

D and then:
1. Make the control unit re-scan the bus by leaving the Installer Menu.

Enabling and Disabling Wired Keypads
30 50 160
If you suspect that a keypad is faulty, and wish to remove it from service temporarily, then
use the Installer Menu option Detectors/Devices – Wired Keypads – Enable Keypad.
(There is a similar option for radio expanders.) Select the keypad you wish to disable and
use the  or  keys to set the enable status to "No".
To return the keypad to service use the same Installer Menu option and set the enable
status to "Yes".
While the keypad is disabled the control unit ignores all signals from the device, but retains
the name and other programming allocated to the device. The disabled keypad shows
flashing red navigation pad LEDs (and will not accept any user input).
All other keypads show an alert (navigation key LEDs glow red). When a user reads the
alert the display shows "Tick to continue Disabled" and the device number of the disabled
keypad.
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 .
Replacing Wired Keypads
30 50 160
If you wish to replace a damaged or malfunctioning keypad with a new keypad, but leave
the old keypad's programming intact on the control unit, then use the Installer Menu option
Detectors/Devices – Wired Keypads – Replace Keypad.
When you use the Replace Keypad option the control unit disables the selected keypad
and retains the keypad's name and other programming. You can then power down the
system, disconnect the damaged keypad from the bus, and reconnect a new keypad (of
the same type) to the bus.
When you power up the control unit again, the remaining keypads will show an alert that
the old keypad has been disabled. Go into the Installer Menu and select
Detectors/Devices – Wired Keypads – Replace Keypad again. The keypad display shows
an "Add" option for the replaced keypad. Select the "Add" option and then hold down the
address request buttons on the new keypad. The control unit will assign the bus device
address of the keypad you removed to the new keypad, along with the name and other
