1. A detector comprising:
- a parameter detector portion operable to detect a parameter;
an acoustic signal detector portion operable to detect a first acoustic signal; and
an alarm portion operable to sound a second acoustic signal upon either one of detection of the parameter by said parameter detector portion and detection of the first acoustic signal by said acoustic signal detector portion.
