Abstract

The present invention provides alarm apparatus (14) comprising at least one light source (16) (preferably an electric light bulb), a detection circuit (preferably a microphone) (32), and a power source (38) therefor, the light source being adapted to attract attention and to be activated when the detection circuit detects a predefined signal, wherein the detection circuit is maintained in constant ready condition and the predefined signal is emitted by a hazard warning device, such as a smoke detector (12), the apparatus serving to reduce response time before activation of the warning light by being on constant standby and being useable with existing hazard warning devices.
