Have I killed my comfort Alarm?

[Krobar]

Hi All,
Was trying to fix the non working smoke detector and suspect I shorted one of the smoke detector inputs. Cant seem to get any lights on the alarm or any of the KP06s at all now. Any hints on which fuses or areas to check? (The 230V input fuse looks intact)

Hmmm, turned off the power, and disconnected and reconnected the battery which brought it back to life.

You may have triggered the resettable fuses due to a short circuit and shut down the power supply
