Abstract

The alarm signal annunciator is fitted in a vessel and will produce a signal when the liquid level exceeds a threshold value. It can be used when filling a bath and will warn the user when the water has reached a given level. The alarm unit consists of a housing with a battery (6) an electrically operated signal generator (2). There is a flexible element (10) connected to a float (16). The switch is located between the signal generator and the battery. The switch will remain open as a result of a weight (17).
