Abstract
1,256,641. Burglar alarm; utilizing energy of radiation. GENERAL ALARM CORP. 21 March, 1969 [27 March, 1968], No. 14924/69. Headings G4N and G6P. A burglar alarm comprises at least one pair of substantially transparent, conductive strips attached to a window pane and an alarm circuit responsive to short- or open-circuiting of said pair of strips. As described, the conductive strips 24a, 24b are preferably formed of tin oxide applied by chemical deposition to a photoresist layer and are protected by a transparent film of silicon monoxide or a transparent polymer. Each pair of strips 24a, 24b is connected to a bias source 30 arranged to reversebias a transistor 44. If one of the strips 24a, 24b becomes interrupted due to fracture of the window pane, transistor 44 is turned on by current in resistor 48. Short circuiting of the pair of strips 24a, 24b will result in sufficient voltage to be developed across diode 42 to turn on transistor 44. Further pairs of strips 24a, 24b may be connected to the alarm circuit 36 via respective transistors 44. Conduction of any one of transistors 44 results in the transistors 70, 72 of the complementary bi-stable circuit, becoming conductive, energizing the alarm relay 64. Key-operated switches 52, 82 are provided to inhibit parts of or the whole circuit. Conductors 28a, 28b may be in the form of a flexible cord connecting the sash with the window frame, the cord being of such length as to permit opening of the window for ventilation but to prevent access by an intruder. A fracture of the cord 28a, 28b will initiate the alarm. Bias sources.-Fig. 5 shows a nuclear battery for replacing source 30 and comprises an isotope of americium encapsulated in a plastic binder 94 and arranged to irradiate a zinc sulphide phosphor coating 92 on a light sensitive strip 90, with light so that the required bias voltage appears on conductors 24a, 24b. Alternatively, a photo-voltaic coating which may form part of the electrically conductive strips may be irradiated by natural or artificial light.
