Firefighters were called to a Timaru home after its occupants mistook the sound of their fridge door for their smoke alarm.

A crew from Washdyke was called to a residential address in Washdyke about 7.40am on Sunday when the occupants mistakenly thought the beeping sound of their fridge door being left open was their smoke alarm going off.

Fire Service Southern Communications shift manager Riwai Grace said it was definitely one of the stranger call outs they have had.

The occupants had left the fridge door open and when they heard the "beeping noise" they rang 111.

He said he did not think a the sound of a fridge door being left open sounded like a smoke alarm but that it was "better to be safe than sorry".
