In a telephone of the type wherein the receiver emits both voice and ringing signals, a gravity switch is electrically connected in parallel to a resistor, and such parallel connected elements are coupled between the ringing circuitry of the telephone and the receiver. Both the receiver and the gravity switch are housed within the telephone handset. When the handset is in its normal position the gravity switch provides a conductive path for the ringing signal from the ringing circuitry to the receiver. However, when the handset is tiltably displaced from its normal position, the conductive path through the gravity switch is broken, thereby causing the ringing signal to traverse the resistor. Passage of the ringing signal through the resistor results in the attenuation of this signal. Thus, when the handset or gravity switch is in its normal position, the receiver emits an audible ringing signal at a predetermined maximum decibel level. However, when the handset is tiltably displaced from its normal orientation, the receiver admits an audible ringing signal of lower decibel level.

Telephone having circuitry for reducing the audio output of the ringing

An alarm system includes a security loop comprising a plurality of sensors, a circuit connected to the security loop and an alarm. The circuit is responsive to a change in condition within the security loop, and upon any change over a threshold value or substantially any change which is rapid, irrespective of value, the responsive circuit functions to enable the alarm. The alarm may be of audible and/or visual-type with additional capability of signalling a remote control center. The responsive circuit includes a network for self-balance thereby to compensate for changes which are responsive to ambient conditions.
