Abstract

1445705 Intruder alarms; alarm systems M GOTANDA 14 Aug 1973 [31 Aug 1972] 38438/73 Headings G4N and G4H [Also in Division H1] A theft prevention device for a room or a building comprises a first switch SW1 located in a recess in a door frame and arranged to be closed upon locking of a door, further switches SW2 actuatable by the opening or closing of a door, a window &c., and a breakable conductor BC disposed adjacent switches SW2, wherein an alarm B2, e.g. a buzzer, is energized from a power source 5 when any of the switches SW2 is opened or the conductor BC is broken. A thyristor SCR is normally biased off and is rendered conducting by a transistor Q when any of the switches SW2 is opened or a conductor BC is broken. In the alternative embodiment of Fig. 2 (not shown), the buzzer is energized by the de-energization of a relay. Figs. 3-12 (not shown) relate to arrangements for locating the switches SW1, SW2 on doors. The door lock switch SW1 may be a magnetically operated reed contact unit. The arrangement of Fig. 14 (not shown) settable by the closing of a single lock switch SW1 includes a plurality of alarm devices A<SP>1</SP> 1 ... A<SP>1</SP> n , each connected to a separate door or window switch SW2 and to a separate neon indicator N 1 ... N n in a check lamp board CL in a controller's room.
