Hi folks. When my daughter a tenant has forgotten the stove off. And the afternoon spent with a friend. Towards evening the fire was 3 fighting vehicles in use. Very important is the individual smoke detectors via radio at the same time appeal. In my townhouse I have therefore replaced all simple smoke alarm against this wireless smoke detector. If there is a fire in the attic is in the lower living room going on the alert. At night in his sleep by a survival but safer.
