Usingthis option defaults the bus device number stored within the device (making the devicesafe to add to other systems). Exit the Installer menu to save the change.Note: Remove all power from the system (battery and mains) before disconnecting anykeypad from the bus.Holding down D and at a keypad while its tamper switch is open clears the address fromthe keypad. Normally, you should clear the address only by using Delete Keypad. If youhave used D and at a keypad that is known to the system and still connected to the bus,you can either power the control unit down and up again for it to recognise the keypad(you will be prompted to press the A and keys), or go to another keypad and use DeleteKeypad to delete the keypad.Enable KeypadUse this option and set the enable status to “No” if you suspect that the device is faulty,and wish to remove it from service temporarily.While the keypad is disabled, the control unit ignores all signals or input from the device,but retains the name and other settings allocated to the device.If a user tries to set the system, the keypad displays “Tick to continue Disabled”, togetherwith the address of the disabled keypad, but will continue to set the system if the userpresses .Replace KeypadUse this option if you wish to replace a wired keypad with a new keypad, but leave thekeypad's configuration intact in the control unit.When you use Replace Keypad, the control unit disables the selected keypad, but retainsthe keypad's configuration. You can then power down the system, disconnect the keypadfrom the bus, and reconnect a new keypad to the bus.When you power up the control unit again, the remaining keypads will show an alert thatthe old keypad has been disabled. Select Replace Keypad again, select the Add optionand then hold down the A and keys on the new keypad. The control unit will assign thebus device address of the keypad you removed to the new keypad, along with all theconfiguration from the old keypad. The new keypad will not need any further configuration.A keypad can be replaced by any other wired keypad of the same or different type (as i-on10 does not support the connection of zones to KEY-KPZ01 or KEY-FKPZ keypads).Note: If you are replacing a keypad on a single-keypad system, you will have to re-program the new keypad with all the functions of the old keypad, including any non-defaultABCD key functions.
