Abstract: A container for an alarm transmitter used in combination with components of a transmitter circuitry which includes voltage control for providing a gated voltage and controlled by a timing circuit. The components also include an audio multivibrator which is electrically coupled to the voltage control in order to receive the gated voltage, a microfork audio filter which is electrically coupled to the audio multivibrator and a modulator which is electrically coupled to the audio multivibrator. The components further include a radio frequency oscillator whose frequency is modulated by the modulator and which has an antenna electrically coupled to its output terminal. The container includes a tubular member which is adapted to be installed into a hole in a wall adjacent to a door or a window and an elongated, rectangular member adapted to be inserted into the tubular member and also adapted to have the components of the transmitter circuitry placed thereon.
