Fuses
230 V mains fuse for mains terminals
The battery connect 'kickstart' button is used to power-up the control panel when there is no mains
supply present. For example: if you wish to program a panel that is being fitted in a new-build
premises before the mains supply has been fully installed. To use it – Hold for 5 seconds and then
release.
► For more information, see "The Printed Circuit Board" on page 17
Ensure that the battery jumper is in the correct position for the capacity of battery that you
have connected – otherwise the panel may under-charge a large battery or over-charge and
damage a smaller battery.
