This alarm is a smoke detector of the photo cell principle. This means that the
alarm checks the air for smoke resulting from fire. It does not detect heat, gas or
fire. If the smoke detector is properly mounted and maintained it will sound an
alarm in an early stage. In the event of a fire this can give you those extra seconds
needed to vacate your home and call the fire brigade. The alarm is designed to
detect smoke. It cannot prevent a fire. Read the instructions through carefully
before using the smoke detector.
