Enter and exit the Installer menu. Select options and change settings in the Installer menu. Reset the control unit.Note: This chapter assumes that all wiring is complete, as described in the i-on10Installation Instructions.Initial Power-up ProcedureWARNING: During initial power-up, sounders and the siren may give an alarm tone. If youare working at the top of a ladder, make sure that the sudden noise does not startle youand cause a fall.Note: The following assumes that the control unit has not been previously configured andthat all keypads have a "null" address (no address previously allocated). If required, pleaserefer to page 23 for details of how to reset an existing system.To configure the system for the first time:1. Connect the control unit's battery.2. Close the lid of the control unit if there is no need to keep it open.3. Switch on the mains supply.Note: Ordinarily, the control unit starts only after the mains supply is switched on,even if a battery is connected. If you want to operate the control unit temporarilyusing only the battery (or a 12VDC supply), start it by briefly shorting the kick-startlink on the PCB.4. Wait until you see:This message indicates that the keypad has a "null" address.5. Go to the keypad you want to use for initial configuration. Obtain an address for thiskeypad by pressing and holding A and keys simultaneously for at least threeseconds until you hear a sound. The display shows the address allocated by thecontrol unit, such as “b1-d01”(bus 1, device 01).The address is now stored in the keypad.
