Abstract

In a space (10) an emitter-receiver device is provided for monitoring of a disturbance in this space by objects projecting into the space, including objects that are not movi0ng and hence cannot be detected by a movement alarm. The device consists of a plurality of component groups each comprising a receiver (E) having a plurality of emitters (S). If the emitters, preferably designed as infrared diodes, are dispersed they can form a three-dimensional triangular configuration (I, II, III, IV) together with the associated receiver, so that using a plurality of emitter and receiver groups will provide complete covering of the space (10). Mutual interference between the different component groups or between the different emitters of one receiver can be prevented by using a signal sequence which checks the relevant emitted signal in the receiver for correlation with the correct emitter. <IMAGE>
