N/A
The smoke alarm chirps audibly every 40 seconds, signalling a low power-pack condition.
The power pack no longer has sufficient capacity for the smoke alarm to operate correctly.
Replace the smoke alarm straight away. The low-power-pack warning will keep sounding for up to 7 days, but if you haven't replaced it by the end of that period, it may no longer have enough charge left to warn you in a genuine fire.
